Brex Business Account: Checking, Treasury, Vault & Business Banking Features

The Brex Business Account is a digital business-banking and cash-management setup built for incorporated startups and scaled companies. It combines a commercial checking account with Treasury and Vault cash-management services, allowing a company to separate operating cash, invested excess cash, and cash placed across program banks for expanded FDIC eligibility inside one Brex platform.

Brex itself is a financial technology company, not a bank. The current Brex Business Account structure consists of Checking provided by Column N.A., Member FDIC, plus Treasury and Vault services provided by Brex Treasury LLC, a FINRA/SIPC member and Capital One company. That distinction is important because the legal structure and protections are different depending on where a company keeps its funds.

For a finance team, the product is broader than a basic business checking account. Brex combines banking-related services with free same-day ACH, domestic and international wires without Brex transaction fees, invoicing, Bill Pay, payment approvals, multiple checking sub-accounts, corporate-card integration, accounting workflows and global payments.

The strongest fit is typically a digital-first incorporated company that already uses, or expects to use, Brex for cards, accounts payable, expenses or cash management. Businesses that rely on cash deposits, ATM withdrawals or physical branches will usually need another banking relationship alongside or instead of Brex.

Important banking clarification: Brex is not a bank. Checking is provided by Column N.A., Member FDIC. Treasury is an investment in a money market fund and is not FDIC-insured. Vault sweeps eligible cash to program banks where FDIC insurance can apply subject to program terms, ownership categories and the customer's deposits at those banks.

Brex Business Account Structure

The easiest way to understand the Brex Business Account is to separate it into three components. Checking is for day-to-day payments and collections. Treasury is for money a company chooses to invest in a government money market fund to seek yield. Vault is for cash a company wants swept across program banks for expanded FDIC insurance eligibility.

Brex Checking

Brex Checking is a commercial checking account provided by Column N.A., Member FDIC. It is the operational center of the Brex Business Account. Companies use Checking to send and receive ACH payments and wires, pay vendors, receive invoice payments, deposit eligible checks through the mobile app, and connect recurring business payments.

Brex currently allows a company to create up to 512 checking sub-accounts. Each can have a distinct account number, statement and ledgered balance, but the sub-accounts are legally part of one demand deposit account owned by the company at Column N.A. The combined Brex checking balances are eligible for up to $250,000 of FDIC insurance, subject to normal FDIC rules.

Brex Treasury

Treasury is not another checking account. Funds allocated to Treasury are invested in the BNY Dreyfus Government Cash Management Fund, DGVXX, through Brex Treasury LLC. The fund invests primarily in cash and securities backed by the U.S. government and seeks to maintain a stable $1.00 net asset value, but it is still an investment and can lose money.

Brex advertises same-hour liquidity during supported market hours, which makes Treasury useful for excess operating cash that the company may need to move back to Checking relatively quickly. Treasury returns are variable and should not be treated as a guaranteed savings-account APY.

Brex Vault

Vault is a cash-management service designed to expand the amount of company cash that can be eligible for FDIC insurance by sweeping funds across Brex program banks. Brex currently advertises up to $6 million in FDIC coverage through 24 partner banks, subject to program conditions and the company's other deposits at those banks.

Vault is useful for businesses holding more cash than the standard $250,000 FDIC limit at one insured bank, but finance teams should not assume every dollar automatically receives coverage. Pass-through insurance depends on legal ownership, account records, funds reaching the program banks and the customer's aggregate deposits at each participating bank.

How the Three Account Types Work Together

A practical setup might place payroll, taxes and near-term vendor payments in Checking, allocate a portion of excess liquidity to Treasury for variable yield, and place another portion in Vault for expanded deposit-insurance eligibility. Brex lets account admins move money among these components, subject to processing rules.

For companies using Brex cards with daily repayment, the aggregate balance across primary Checking, Treasury and Vault can also affect available card capacity. This makes cash-management decisions directly relevant to the card program.

Brex Checking Account

Column N.A. Banking Relationship

The checking portion of the Brex Business Account is provided by Column N.A., Member FDIC. Brex provides the software experience and payment workflows, while Column is the regulated bank providing the commercial deposit account.

Account and Routing Numbers

Each checking account has account details that can be used for inbound ACH, wires and recurring bills. Brex provides account-verification letters for third parties that require banking confirmation; it does not rely on a conventional voided-check workflow.

Operating Cash

Checking is the appropriate Brex component for money needed for near-term operations because outbound vendor payments and external receipts are initiated from Checking. Treasury and Vault funds generally need to move through Checking before certain external payments are sent.

ACH Payments

Brex supports inbound and outbound ACH. Its current product page promotes unlimited same-day ACH payments at no extra cost, subject to processing cutoffs and risk controls. Incoming ACH timing depends on how the transfer is initiated and can range from same-day to several business days.

Domestic Wire Transfers

Domestic wires can be sent from Checking and are generally processed the same business day when initiated before applicable cutoffs. Brex does not charge a Brex transaction fee for domestic wires, although intermediary or recipient financial institutions can impose their own fees.

International Payments

Brex supports international wires and local-currency payments in supported markets. USD and foreign-currency international wires can have different delivery times, and non-USD transfers use a Brex-selected foreign exchange rate.

Recurring Payments

Outgoing transfers can be scheduled for future dates or on recurring weekly, monthly or custom schedules. This is useful for predictable vendor or intercompany obligations.

Payroll and Vendor Payments

A company can use Brex checking account details for payroll funding and vendor payments. Brex also integrates the account with Bill Pay and accounting workflows, giving finance teams a more controlled way to manage AP than manually initiating each transfer at a separate bank portal.

Brex Treasury

Treasury Cash Management

Treasury is designed for cash that a company does not need to leave idle in Checking but may still need to access on relatively short notice. It invests through a money market fund rather than a bank savings account.

Money Market Fund Structure

Current Brex disclosures identify DGVXX, the BNY Dreyfus Government Cash Management Fund, as the Treasury investment. The fund is designed to preserve capital and maintain liquidity and holds government-backed instruments, but neither Brex nor the fund guarantees a $1 share value.

Current Treasury Return

On October 7, 2026, Brex's live product page advertised total Treasury returns ranging from 3.56% to 3.91%, with the highest tier available to customers with the largest total Brex balances. The displayed total return combines the money market fund yield with an additional Brex-provided return and assumes reinvestment. Because both the fund yield and Brex tier schedule can change, any published rate should be date-stamped.

Variable Yield Explained

The Treasury number is not a fixed bank APY. Fund yields change with market conditions, and Brex can change its balance-tier additional return. Realized returns can therefore be lower or higher than a displayed annualized estimate.

Same-Hour Liquidity

Brex states that Treasury funds can move to or from Checking as quickly as one hour during supported business-day market windows. This is useful for treasury management, but it is not identical to an always-instant checking balance.

Investment Risk

Treasury is an investment product. The fund seeks stability but may lose value. A company should not place funds in Treasury merely because the quoted return is higher than checking without considering liquidity needs and investment risk.

SIPC vs FDIC Protection

Treasury funds are not FDIC-insured. Brex Treasury LLC is a FINRA/SIPC member, but SIPC protection addresses the failure of a brokerage and missing customer securities or cash within applicable limits; it does not insure investment performance or protect against losses because a money market fund declines in value.

Brex Vault

Vault Account Structure

Vault is offered through Brex Treasury LLC as a cash sweep service. Instead of investing the money in a money market fund, Brex directs eligible cash to a network of program banks.

Program Bank Sweep

The sweep network distributes funds across multiple participating banks. The purpose is to reduce concentration at a single insured bank and increase the amount that can potentially qualify for FDIC deposit insurance.

Expanded FDIC Coverage

Brex currently advertises up to $6 million in FDIC coverage through 24 program banks. This is materially higher than the standard $250,000 limit at one insured bank, but the exact insured amount depends on program conditions and the customer's existing deposits.

How the $6 Million Coverage Works

FDIC coverage is applied per depositor, per insured bank, per ownership category. If the company already has deposits directly or indirectly at a program bank, those deposits can reduce available pass-through coverage for Brex Vault funds at that same bank.

Program Bank Limits

Funds are not FDIC-insured by virtue of simply appearing in the Brex interface. Brex states that Vault funds become eligible for FDIC insurance after they arrive at participating program banks and if the relevant pass-through requirements are satisfied.

Vault vs Treasury

Vault prioritizes deposit-insurance distribution; Treasury prioritizes variable investment return. A finance team deciding between them is making a risk, liquidity and yield allocation decision - not merely choosing between two savings buckets.

Brex FDIC Insurance Explained

Checking FDIC Coverage

Brex checking sub-accounts are held through Column N.A. and collectively are eligible for up to $250,000 of FDIC insurance under the applicable ownership category, subject to standard FDIC requirements.

Vault FDIC Coverage

Vault can provide substantially more potential coverage by distributing cash across multiple program banks. Brex currently markets up to $6 million of FDIC eligibility.

Treasury Is Not FDIC-Insured

Money in Treasury is invested in securities and is not a bank deposit. It is therefore not protected by FDIC deposit insurance.

Deposit Ownership Categories

FDIC insurance is calculated by depositor, insured bank and ownership category. A company should not simply multiply the number of accounts it has by $250,000. Multiple Brex checking sub-accounts remain part of the same underlying deposit relationship.

Existing Deposits at Program Banks

If the company already holds money at one of Vault's program banks, that balance can count toward the same insurance limit. Treasury teams holding substantial cash should review the program-bank list and their existing bank relationships.

FDIC Coverage Limitations

FDIC insurance protects eligible deposits if an insured bank fails. It does not protect against fraud losses in every circumstance, investment losses, or operational losses unrelated to a bank failure. Conditions for pass-through insurance also matter.

Brex Business Account Fees

Monthly Account Fees

Brex advertises business banking with no hidden fees, while its broader software plans start at $0 per user per month. Premium is currently priced at $12 per user per month, and Enterprise uses custom pricing. The account itself should therefore be separated from optional software-plan costs.

Minimum Balance Requirements

Brex advertises no minimum for Treasury and no minimums on the Business Account product page. Eligibility for the overall Brex relationship can still depend on company size, funding, revenue and other criteria.

ACH Fees

Brex currently does not charge transaction fees for ACH payments from the Brex Business Account and advertises free same-day ACH. Processing eligibility and timing still depend on cutoffs and risk controls.

Domestic Wire Fees

Brex does not charge a Brex-issued domestic-wire fee. Other banks involved in the transfer may charge the sender, intermediary or recipient.

International Wire Costs

Brex does not charge a per-wire Brex transaction fee for international wires, but correspondent and recipient banks may charge fees. Non-USD wires also involve foreign-exchange pricing selected by Brex.

Foreign Currency Costs

International wires in a currency other than USD use a Brex-selected exchange rate. The absence of a per-wire fee therefore does not mean the currency conversion has no economic cost.

Brex Software Plan Costs

Advanced controls, custom roles, multi-entity tools and other features may require Premium or Enterprise. Finance teams should evaluate total software cost rather than assuming all account functionality is included in the free tier.

Other Potential Costs

Money market funds have their own expenses, and third-party banks can impose transfer fees. Contract-specific services or overages can also create costs depending on the company's Brex plan.

Sending and Receiving Money

ACH Transfers

Brex supports inbound and outbound ACH from Checking. Incoming Brex-initiated ACH debits can take roughly 0-3 business days, while externally initiated ACH credits commonly take 1-2 business days. Timing varies by direction, cutoffs and risk review.

Same-Day ACH

Brex markets free same-day ACH when funded from the Brex Business Account. Same-day treatment remains subject to banking cutoffs, holidays, amount/risk constraints and processing conditions.

Domestic Wires

Outgoing domestic wires are generally completed the same business day when submitted before the applicable cutoff. Incoming domestic wires are usually available within one or two business days.

International Wires

Outbound international wires usually leave Brex within one business day, while final delivery can take longer because several institutions may be involved. Incoming international wires can take several business days.

Incoming Payments

Businesses can receive ACH, domestic and international wires, eligible mobile check deposits and customer invoice payments into Brex Checking.

Scheduled and Recurring Transfers

Payments can be sent immediately or scheduled for later. Brex supports recurring weekly, monthly and custom schedules for predictable outgoing transfers.

Transfer Limits and Processing Times

Actual limits and processing speeds can depend on company risk settings, transaction type, account history, destination and cutoffs. Treasury and Vault balances may need to move to Checking before an external wire is sent.

International Business Payments

Supported Currencies

Brex's current Business Account page advertises payments in more than 30 local currencies. Exact country and currency support changes, so finance teams should check the current Brex supported-country list before designing a global payment workflow.

International Vendor Payments

Businesses can use international wires and, in supported configurations, local transfer rails to pay overseas vendors. Brex Bill Pay can also handle foreign-currency invoices in supported countries.

USD International Wires

A company can send an international wire denominated in U.S. dollars. The receiving institution may convert the funds into local currency at its own rate.

Local-Currency Payments

When Brex sends a supported local-currency wire, the company funds the payment in USD from the Brex Business Account and Brex applies its selected foreign-exchange rate.

Currency Conversion Costs

No per-wire Brex fee does not equal zero FX cost. Exchange-rate spreads and bank charges should be included when comparing international-payment economics.

International Payment Information Requirements

Cross-border payments can require beneficiary bank details, legal entity data, address information and purpose-of-payment details. Some countries and regions are restricted or unsupported, and the list can change.

Brex Bill Pay

Vendor Bill Management

Brex Bill Pay converts invoices into payable items inside the same platform used for banking and expense management. Bills can be uploaded or automatically forwarded to Brex.

Bill Approval Workflows

Companies can configure approval chains so higher-value or unusual bills receive the correct review before payment. AP clerks can draft payments while admins or users with payment authority approve and release them.

ACH and Wire Payments

Approved bills can be paid using supported rails such as ACH, wire or certain card-based methods. Funding can come from the Brex Business Account or other supported sources depending on configuration.

Recurring Vendor Payments

Regular bills and vendor obligations can be scheduled, reducing repetitive manual work while preserving approval and accounting controls.

Accounting Integration

Brex can sync bills with accounting systems such as QuickBooks Online, NetSuite, Sage Intacct and Xero, depending on integration and plan.

Accounts Payable Automation

The value of Bill Pay is not only payment execution. A finance team can move from invoice intake to approval, payment and accounting sync inside one workflow, reducing manual handoffs.

Brex Invoicing

Creating Business Invoices

Authorized users can create branded invoices with customer information, line items, due dates, tax, discounts, PO numbers and attachments.

Sending Invoices

Invoices are emailed to customers and can include payment instructions or a Brex-hosted payment link. Companies can also schedule repeating weekly or monthly invoices and send automated reminders.

Receiving Customer Payments

Invoice proceeds can be deposited directly into a selected Brex Checking account by ACH, domestic wire or international wire. Brex invoices are denominated in USD.

ACH Invoice Payments

Eligible customers can pay through ACH direct debit by connecting a U.S. bank account. Brex marks the invoice paid after the funds are received, which can take several business days.

Invoice Tracking

The Brex dashboard tracks invoice status and payment progress, helping finance teams monitor receivables without maintaining a separate manual spreadsheet.

Accounting Sync

Brex supports an early-access QuickBooks Online invoice sync that can export invoice information and map items to general-ledger accounts.

Business Account and Brex Corporate Cards

Daily-Pay Card Integration

For Brex cards on daily repayment, the company's available card capacity is tied closely to its Brex Business Account balances.

Business Account Balance and Card Capacity

Brex states that aggregate balances across primary Checking, Treasury and Vault can contribute to daily-pay limits. As card spending occurs, available capacity can decline with the account balance.

Automatic Card Repayment

Daily card payments are automatically funded from the primary Checking balance first, with Treasury and Vault used in the order Brex specifies if additional funds are needed.

Employee Spending

The Business Account does not replace card-level controls. Employees can receive their own cards and spend limits while the company maintains centralized cash and account-level control.

Corporate Card Controls

Combining the Business Account with the Brex card means finance can manage cash, payment capacity, employee spend, AP and expense reporting inside one platform. The trade-off is greater operational dependence on Brex.

Managing Business Cash in Brex

Operating Cash in Checking

Keep near-term obligations in Checking when the company needs direct access for payroll, ACH, wires and vendor payments.

Excess Cash in Treasury

Treasury can be considered for cash that is not required immediately and where the business accepts investment risk in exchange for variable return.

Protected Cash in Vault

Vault can be useful for businesses prioritizing expanded FDIC eligibility over money-market yield.

Automatic Transfers

Brex can automate Treasury top-ups and supports internal transfers between account components, helping finance teams maintain target liquidity levels.

Liquidity Planning

Treasury and Vault are not identical to Checking. Finance should keep enough operational cash immediately available to avoid unnecessary transfer timing risk around payroll, taxes, card repayment and critical vendors.

Cash Concentration Risk

Using one platform for banking, cards and AP simplifies operations but increases concentration. Companies holding substantial balances may still choose to maintain a secondary external bank for resilience, lending relationships or emergency access.

Brex Business Account Eligibility

Eligible U.S. Business Structures

Brex focuses on incorporated startups and scaled businesses. Sole proprietorships and other unincorporated structures are not the core eligible profile.

EIN Requirements

Applicants need a U.S. EIN issued by the IRS.

U.S. Incorporation

Brex requires valid U.S. incorporation for applicants to its U.S. account program.

Physical U.S. Address

Applicants must have a verifiable physical U.S. address. P.O. boxes and private mailbox services do not satisfy the requirement. A beneficial owner or control officer may need a verifiable U.S. residential address when a business uses a virtual address.

Business Activity Requirements

Brex evaluates the business model, source of funds, spending patterns and industry. Restricted industries or risk profiles can be declined even when baseline requirements are met.

Sole Proprietor Restrictions

A sole proprietor looking for traditional small-business checking should generally consider another provider. Brex is built around incorporated entities.

Business Verification

Brex can request formation data, ownership/control-person information, address documents, bank statements and other records needed for KYC and risk review.

Opening a Brex Business Account

Application Process

New companies apply to Brex and provide company, ownership and business information. Existing Brex card customers can apply for the Business Account from Company settings when eligible.

Business Information Required

Expect to provide legal company name, EIN, formation information, physical address, business activity and other company details.

Beneficial Owner Verification

Brex must identify and verify beneficial owners and control officers under financial-services compliance requirements. Personal identifying information may therefore be required even though Brex is evaluating the company rather than offering a consumer account.

Financial Documentation

Depending on the business profile, Brex may request bank statements, financial statements, proof of funding or other evidence of financial activity.

Application Review

Meeting the published requirements does not guarantee approval. Brex considers risk and whether the company fits the customer profile it is designed to serve.

Account Approval

After approval, account admins can configure Banking, link external accounts, set permissions and establish payment workflows.

First Deposit and Account Activation

The Business Account can be funded by ACH, wire, eligible mobile check deposit or other supported sources. Companies cannot deposit physical cash.

Multiple Brex Business Accounts

Multiple Checking Accounts

Brex currently allows up to 512 checking sub-accounts under one approved Brex Business Account. These can be used to separate payroll, taxes, AP, revenue collections or specific operational budgets.

Separate Operating Accounts

Each sub-account can have a distinct account number, statement and ledgered balance, making internal cash organization cleaner than using one undifferentiated checking balance.

Entity-Level Accounts

The Brex Business Account is legally tied to the primary contracted entity. Adding a subsidiary entity in the Brex software does not automatically create a separate bank account for that subsidiary.

A different legal entity that needs its own Brex Business Account generally must submit a separate application. Brex can still support multi-entity spend management within eligible plans.

Transfers Between Company Accounts

Internal transfers between Brex checking sub-accounts can be instant. Separate legal Brex accounts can be set up as counterparties/vendors when intercompany transfers are needed.

User Roles and Account Permissions

Account Admin

The Account Admin has the highest banking access. This role can view balances, connect external banks, manage users and integrations, initiate payments and configure account settings.

Finance and Accounting Users

Companies can give finance personnel access appropriate to their responsibilities rather than sharing one admin login.

Bookkeeper Access

Bookkeepers can receive accounting and read-only banking access without automatically gaining full payment authority.

Payment Permissions

Brex separates the ability to draft a payment from the ability to approve or release funds. This supports segregation of duties.

Custom Roles

Premium and Enterprise customers can create custom roles that grant selected banking, accounting, bill-pay, reporting and other capabilities.

Approval Controls

When multiple admins or AP users are involved, Brex can require approval of outbound money movement and notify approvers by dashboard task, email or mobile push.

Brex Business Account Security

Payment Approval Rules

Approval rules reduce the risk that one employee can unilaterally initiate and complete a large payment. Finance teams should configure these rules according to transaction amount and role.

Vendor Safe Lists

Brex supports controls over external ACH debits, including allow/block approaches. Companies can use separate checking accounts for externally initiated debits to reduce exposure of the primary operating account.

Account Access Controls

Banking visibility and payment authority can be restricted by role. Card Admins, for example, do not automatically receive the same banking access as Account Admins.

Multi-Factor Authentication

Brex account security uses MFA and device verification. Banking users should protect admin credentials especially carefully because those roles can move company funds.

Fraud Monitoring

No software control eliminates fraud risk. Companies should combine Brex alerts and controls with internal vendor-verification procedures, dual approvals and callback verification for changed payment instructions.

Business Account Verification Documents

Brex provides downloadable account verification letters. Vendors requesting bank verification should receive approved documentation rather than screenshots of sensitive account settings.

Accounting and Financial Integrations

QuickBooks

Brex supports QuickBooks Online workflows for accounting, Bill Pay and invoice syncing. The exact feature set depends on product and rollout status.

Xero

Xero is supported for Brex accounting and bill-sync workflows.

ERP Integrations

Brex also integrates with larger accounting systems such as NetSuite and Sage Intacct. Premium and Enterprise plans offer more customization.

Payroll Platforms

A Brex Checking account can be used as a business funding account for payroll, and Brex advertises connections across payroll, ERP and HRIS systems.

Ecommerce Platforms

Companies can receive transfers from supported external platforms into Brex. The Business Account should be treated as the bank destination, while ecommerce processors maintain their own payout rules.

Stripe, PayPal and Shopify

Payment processors can generally pay out to Brex Checking using the company's account and routing details, subject to processor rules and account-name verification.

Transaction Export and Reconciliation

Brex provides statements and transaction exports and can sync approved transaction data into accounting software, reducing manual reconciliation.

Cash Deposit, Check and ATM Limitations

Cash Deposits

Brex does not support physical cash deposits. Restaurants, retail stores and other cash-heavy businesses will need another bank or cash-handling service.

Check Deposits

Brex does support mobile deposit of eligible physical checks through the Brex app for authorized users. Brex says checks typically clear in roughly 2-5 banking days. It does not accept mailed check deposits.

Cash Withdrawals

Brex does not provide cash withdrawal functionality from the Business Account.

ATM Access

There is no Brex ATM-access model for withdrawing company funds from the Business Account.

Physical Branch Access

Brex is digital-first and does not offer a branch network. Companies requiring frequent in-person banking will need a traditional banking relationship.

Check Capabilities

Brex can send outbound checks to recipients and accept supported mobile check deposits, but it does not function like a traditional branch bank with teller services or standard paper-check handling for every use case.

Businesses That Still Need a Traditional Bank

A company may keep Brex for cards, AP, wires and Treasury while retaining a conventional bank for cash deposits, branch services, loans, safe-deposit services or a second operational backup.

Brex Business Account Advantages and Limitations

AdvantagesLimitations
Checking, Treasury and Vault in one finance platformNo cash deposits or ATM withdrawals
No Brex transaction fees for ACH, domestic wires and international wiresSelective company eligibility
Free same-day ACH promoted on current product pageTreasury is an investment, not an FDIC-insured deposit
Up to $6M Vault FDIC eligibility through program banksFDIC coverage depends on conditions and existing deposits
Variable Treasury return with relatively fast liquidityTreasury return is variable and principal can be at risk
Integrated Bill Pay and invoicingNo physical branches
Up to 512 checking sub-accountsAdvanced software features can add per-user cost
Strong corporate-card integrationConcentrating banking, cards and AP in one platform increases vendor dependence

Banking Partner Dependence

Because Brex is not a bank, core deposit services depend on partner institutions. This is common among fintech platforms but creates a different legal and operational structure from opening directly with one bank.

Treasury Investment Risk

A money market fund can seek a stable value without guaranteeing it. Treasury should not be described as insured savings.

Digital-Only Banking Trade-Offs

Digital payments and finance automation are strong; cash handling and branch service are weak. The best fit depends on how the company actually moves money.

Best-Fit Businesses for Brex Business Account

Venture-Backed Startups

Funded startups often hold significant cash, use corporate cards heavily and need fast digital payments. Brex combines those workflows effectively.

Technology Companies

Software and internet businesses are typically well suited to digital-only banking because they rarely need branch cash services and often value automated AP and accounting integration.

Mid-Market Businesses

Larger finance teams can benefit from multiple checking accounts, approvals, custom roles, ERP integration and centralized reporting.

Companies Holding Significant Cash

Vault and Treasury make Brex more relevant to companies holding balances well above normal day-to-day checking needs.

Businesses Using Brex Cards

The Business Account integrates directly with Brex card payment and daily-limit mechanics, creating operational simplicity for existing Brex card customers.

Finance Teams Managing AP and Spend

Companies wanting banking, Bill Pay, cards and expense management in one platform are closer to Brex's intended use case than businesses simply looking for a free checking account.

Businesses That May Need Another Account

Sole Proprietors

Unincorporated businesses should generally look at mainstream small-business checking providers.

Cash-Heavy Businesses

Businesses that regularly receive physical cash need a bank or service that accepts cash deposits.

Businesses Needing Branch Banking

Companies relying on teller services, notarization, branch cash management or in-person banking will find Brex incomplete as a sole banking relationship.

Companies Needing Regular ATM Access

Brex does not offer ATM cash withdrawals from the Business Account.

Very Small Businesses

A small owner-operated company may not benefit enough from Treasury, AP controls, corporate cards and multi-user workflows to justify the platform complexity.

Companies Wanting Simple Traditional Checking

If the only requirement is basic checking, a direct bank relationship may be easier to understand and maintain.

Brex is strongest where a company values software-driven financial operations. A traditional bank is stronger where physical banking, lending relationships, cash handling or a direct depository-institution relationship matters more.

Brex Business Account vs Mercury

Brex and Mercury are often compared because both target technology startups and both are fintech platforms rather than FDIC-insured banks. In 2026, however, their product structures differ in important ways.

Corporate spend managementMajor part of Brex platformAvailable, but banking remains a central Mercury identity
Best fitCompanies wanting cards + banking + AP + spend management togetherStartups wanting banking-first workflow with cards and finance tools

Banking Structure

Both platforms rely on partner banks for deposit accounts. Brex uses Column for Checking and separately offers Treasury/Vault through Brex Treasury LLC. Mercury currently uses Choice Financial Group and Column for its business deposit accounts.

FDIC Coverage

Brex Vault markets up to $6 million of eligible FDIC coverage, while Mercury markets up to $5 million through its partner-bank sweep structure. In both cases, actual coverage depends on program terms and existing deposits.

Treasury and Yield

Both offer investment-based treasury products rather than FDIC-insured savings. Brex Treasury and Mercury Treasury use different fund/advisory structures and fee/return models, so headline yields should not be compared without reading the disclosures.

ACH and Wire Transfers

Both support strong digital money movement. Brex specifically states it does not charge transaction fees for ACH, domestic wires or international wires from its Business Account.

Corporate Cards and Spend Management

Brex's identity is more deeply tied to corporate cards, employee spend controls and expense management. Mercury can be a cleaner banking-first choice for some startups.

Best-Fit Business

Brex is more compelling when finance wants one environment for cards, AP, banking and spend governance. Mercury can be more compelling when the primary need is startup banking with a simpler banking-centric experience.

Brex Business Account Alternatives

Mercury

A close digital-first startup-banking competitor with checking/savings, Treasury, cards, payments and finance tools.

Traditional Business Banks

Chase, Bank of America, Capital One and other traditional institutions can be stronger for branch access, lending relationships, cash deposits and conventional banking needs.

Online Business Banks and Fintechs

Bluevine, Relay, Rho and other online platforms may fit companies seeking higher-yield checking, cash-flow segmentation or different eligibility requirements.

Choosing an Alternative by Business Need

Do not choose an alternative solely from a feature checklist. Start with the missing capability: cash deposits, loans, fixed credit, higher yield, simpler eligibility, global payments, accounting workflow or branch access.

Brex Business Account After the Capital One Acquisition

Capital One Ownership

Capital One completed its acquisition of Brex on April 7, 2026. Current Brex disclosures identify Brex LLC as a wholly owned subsidiary of Capital One, N.A.

Column Banking Relationship

Despite Capital One ownership, current Brex disclosures still state that Checking is provided by Column N.A., Member FDIC. Users should rely on current account agreements rather than assuming Capital One is the deposit bank.

Brex Treasury Structure

Treasury and Vault remain offered through Brex Treasury LLC, which Brex describes as a Capital One company and FINRA/SIPC member.

Current Product Continuity

Brex continues to operate its own Business Account product, dashboard, pricing, support and account structure after the acquisition.

Areas Businesses Should Continue to Monitor

Ownership changes can eventually affect partner banks, pricing, investment products, eligibility or software strategy. Finance teams should recheck legal disclosures, rates and program-bank terms periodically.

Brex Business Account Assessment for 2026

Strongest Banking Use Cases

Brex is strongest for incorporated digital-first companies that want to centralize operating cash, excess-cash management, cards, AP and finance controls without relying on branches or cash deposits.

Main Operational Weaknesses

No ATM cash access, no physical cash deposits, selective eligibility and investment complexity around Treasury are the biggest structural limitations. Companies should also understand the partner-bank and broker-dealer model before treating Brex like a traditional bank.

Overall Business Fit

The Brex Business Account is best viewed as a finance operating platform with banking components. For the right company, that integration can be more valuable than a conventional checking account. For a cash-heavy or very small business, it can be the wrong tool.

Frequently Asked Questions About the Brex Business Account

What is the Brex Business Account?

It is Brex's business-banking and cash-management product combining Checking through Column N.A. with Treasury and Vault services through Brex Treasury LLC.

Is Brex a bank?

Is Brex Business Account a checking account?

Which bank provides Brex Checking?

Current Brex disclosures identify Column N.A., Member FDIC, as the provider of the commercial checking account.

Is Brex FDIC insured?

How much FDIC insurance does Brex provide?

Brex Checking is eligible for up to $250,000 at Column under applicable FDIC rules. Vault currently advertises up to $6 million of FDIC eligibility through program banks, subject to conditions.

How does Brex Treasury work?

The company allocates money to a Treasury brokerage account where it is invested in the DGVXX government money market fund. Returns are variable, and funds can be moved back to Checking subject to processing windows.

Does Brex Business Account earn interest?

Checking itself should not be treated as an interest-bearing savings product. Treasury can generate a variable investment return on funds allocated to the money market fund.

What is the current Brex Treasury yield?

Brex's live product page showed up to a 3.91% total Treasury return on October 7, 2026. The number is variable, tiered and can change, so verify the current rate before publishing or making a cash-management decision.

Does Brex have a monthly account fee?

Brex's broader plans start at $0 per user per month, while Premium is currently $12 per user per month and Enterprise is custom. Some advanced software capabilities therefore carry cost even when core banking transaction fees are $0.

Does Brex require a minimum balance?

The current product page advertises no Treasury minimum. Overall Brex eligibility can still depend on company funding, revenue, business type and other factors.

Are Brex ACH transfers free?

Brex currently says it does not charge transaction fees for ACH transfers from the Business Account and markets free same-day ACH, subject to processing rules.

Does Brex support same-day ACH?

Yes. Brex currently advertises unlimited free same-day ACH from its business checking product, subject to cutoff and processing conditions.

Does Brex support wire transfers?

Yes. Brex supports domestic and international wires from Checking.

Can Brex send international wires?

Yes, to supported countries and currencies. Brex does not charge a per-wire transaction fee, but FX pricing and third-party bank fees can apply.

Can Brex receive international payments?

Yes. Businesses can receive supported international wires into Checking. Invoicing can also accept international wire payments, with invoice proceeds ultimately received in USD.

Can I deposit cash into Brex?

No. Brex does not support physical cash deposits.

Can I deposit checks into Brex?

Yes. Authorized users can deposit supported checks through the Brex mobile app. Brex does not accept mailed check deposits.

Does Brex have ATMs?

No. The Business Account does not provide ATM cash withdrawal access.

Does Brex have physical branches?

Can an LLC open a Brex Business Account?

A qualifying U.S. incorporated LLC can apply if it meets Brex's broader business, address and risk requirements.

Can a sole proprietor open a Brex account?

Brex is focused on incorporated businesses and does not position the Business Account as a sole-proprietor checking product.

How many Brex checking accounts can a company create?

Current Brex support documentation says up to 512 checking sub-accounts can be created within one Brex Business Account.

Is Brex better than Mercury?

Not universally. Brex is especially strong for companies combining banking with corporate cards, AP and spend management. Mercury may be a better banking-first choice for some startups. Compare eligibility, Treasury structure, FDIC coverage, cards, software workflows and support rather than only headline yield.

Editorial Bottom Line

The Brex Business Account is not simply a startup checking account. Its real value comes from combining operating cash, short-term cash management, payment infrastructure, corporate cards, Bill Pay, invoicing and finance permissions inside one environment.

Checking through Column N.A. handles day-to-day business money movement. Treasury gives companies a way to invest excess cash in a government money market fund and seek variable return. Vault provides a separate path for distributing cash across program banks for expanded FDIC eligibility. Those three components solve different problems and should not be treated as interchangeable balances.

For a venture-backed startup or scaled digital company, the integration can be compelling. A finance team can segment cash into hundreds of checking sub-accounts, send ACH and wires without Brex transaction fees, automate AP, collect customer payments, control employee card spending and manage accounting from the same platform.

The trade-offs are just as important. Brex is not a bank. Treasury is not FDIC-insured. The platform does not accept physical cash deposits or provide ATM cash withdrawals, and advanced software capabilities can create subscription cost. Companies that depend on branch banking, cash handling or revolving bank credit will often need another financial institution alongside Brex.

The strongest 2026 use case is therefore not 'a business that needs a free checking account.' It is an incorporated company with meaningful digital financial activity that wants banking, treasury management and spend operations to work together. For that profile, Brex can be a strong finance platform. For businesses with traditional banking needs, a direct bank or another fintech may be a better fit.
