Brex is more selective than many mainstream small-business credit cards.
All applicants must first satisfy baseline business requirements. Additional financial thresholds depend on whether the company is applying for daily or monthly payments.
Eligible Business Structures
Brex accepts formally registered U.S. companies such as C corporations, S corporations, LLCs and LLPs.
Individual consumers, sole proprietors and unincorporated partnerships are not currently eligible to open a Brex account.
This is an important distinction from traditional business credit cards, many of which allow a sole proprietor to apply using an SSN and business income.
Brex is designed around a legally separate company entity.
U.S. Incorporation and EIN
Every applicant currently needs a valid U.S. incorporation, an EIN issued by the IRS, U.S. business operations and a physical U.S. address.
Meeting those requirements only allows the company to be considered. It does not guarantee approval. Brex also reviews business model, source of funds, spending patterns and other risk factors.
Physical U.S. Business Presence
Brex requires a verifiable physical U.S. address.
A standard P.O. box or private mailbox does not satisfy the physical-address requirement. When a company uses a virtual business address, Brex may need to verify a physical residential address associated with a beneficial owner or control officer.
Applicants may be asked for supporting documents such as utility bills, leases or recent bank statements.
The purpose is company and identity verification, not simply credit underwriting.
Revenue and Cash Requirements
Brex does not publish one universal minimum revenue or cash requirement for all applicants.
The threshold depends on business type and repayment structure.
For daily payments, Brex currently says companies may qualify by meeting at least one of several criteria, including having received equity investment, generating more than $500,000 in annual revenue, or being an eligible technology startup referred through a Brex customer or partner path.
For monthly payments, underwriting becomes more specific.
Funded Startup Eligibility
Funded startups are one of Brex's core customer groups.
For venture-funded or accelerator-backed startups seeking monthly payments, Brex currently publishes a general minimum cash requirement of $50,000, although certain partner referrals can result in lower thresholds.
This does not mean depositing $50,000 automatically produces approval.
Brex still reviews factors including business model, funding source, cash position, financial health and spending behavior.
Commercial and Mid-Market Businesses
Brex also serves businesses outside the venture-backed startup market.
Current published monthly-payment guidelines state that a commercial business generally needs more than $500,000 in annual revenue.
A mid-market or enterprise company generally needs more than $400,000 per month in revenue, equivalent to roughly $4.8 million annually.
These thresholds are important because some third-party Brex reviews quote older or different figures. For current eligibility, Brex's official documentation should take priority.
Sole Proprietor Restrictions
A sole proprietor cannot currently use the standard Brex application structure available to incorporated companies.
This makes Brex fundamentally different from many mainstream small-business cards.
A freelancer, consultant or one-person business operating without a separate incorporated entity will normally need to look at another issuer.
