Corporate-card vendor check, starting with Brex

A corporate card can look like a small administrative win until an invoice arrives in a currency the card does not handle well. Before approving one, run a five-point vendor check against the company's actual age, entity, and spend mix: entity and operating-history eligibility, EIN-only credit application, reward categories versus actual spend, fee/FX exposure, and spend-control fit. Brex is a useful first test because its startup card lets founders apply for credit with an EIN instead of a personal SSN.

The card is a vendor, not a perk

Founders often approve the card because it pays for itself in points. The harder question is whether the issuer can underwrite the company without turning the founder into a guarantor. That changes the balance sheet, the bank relationship, and the speed at which the team can pay vendors. A card that looks cheap in the rewards table can still be expensive in the way it constrains the company.

Pull the recent invoice stack, the entity documents, and the current bank statement before the vendor call. The check should compare the card against the company's actual shape, not the company the founder hopes to have next quarter. If an answer is unclear, the card is not ready. The decision should be explainable to the bank, the accountant, and the next investor without relying on the vendor's sales deck.

The check should start from actual documents

• Confirm the entity type and operating history meet the issuer's eligibility rules.
• Confirm the credit application can be completed without a personal credit file.
• Compare reward categories against recent actual spend.
• Total annual fees, foreign-currency costs, and any hidden costs.
• Check spend controls against the way the team actually pays for things.

Most EIN-only issuers require an LLC, S-corp, C-corp, or partnership, plus one to two years of operating history, actual revenue, and cash reserves. A brand-new entity may still get a card, but the underwriting assumptions are different. Know which assumptions apply before the application is submitted, because they set the terms the company will live with after approval.

A personal credit file changes who is exposed to the company's spend. If the application requires one, the founder is signing up for a different risk profile. The card may still be useful, but the decision is no longer purely operational. It also changes how the company talks to lenders later, because the founder's personal obligations become part of the story. An EIN-only path is worth the extra diligence when it keeps that exposure out of the founder's file.

Brex's points rewards include 2x on software and 4x on travel booked through Brex, including flights and prepaid hotels. If the company's spend is mostly payroll, equipment, or local services, those multipliers may not move the needle. Read the reward table against recent invoices, not the brochure. A high rate on a category the company rarely touches is just a better-looking empty line. The useful calculation is simple: multiply each category's recent spend by its rate, then compare the result to the card's cost.

In September 2026, the starter kit a new company buys cost $4,417, a 14% increase from 2023. A card fee is easier to absorb when the company's baseline spend is already rising. Brex's card is aimed at global companies because it has no foreign transaction fees and can handle dozens of currencies. Total the annual card cost, the cost of currency conversion, and the cost of any unused features. FX exposure includes the conversion cost on every cross-border invoice, and it can outpace the reward math quickly.

Brex had more than 35,000 customers spending billions of dollars on its platform. That scale matters because a card that cannot match the way a team actually spends will create workarounds. The controls should fit the operating rhythm, not force a different rhythm. If the team has to route normal purchases through an exception process, the card is adding friction instead of removing it. The right controls make the team's normal spend visible, without turning every routine purchase into a negotiation.

Brex is a fair test case

Run the same check against any issuer. If the answers line up, the card is a tool. If they do not, the card is a liability with a nicer logo. The operator should be able to say which answer changed the decision. A card that passes the check is a controlled expense with a measurable return.
