Brex Business Card

Nobody searches for a business card because they want a business card. They search because company money and personal money have become tangled, and they want a clean separation with as little administrative overhead as possible.

That underlying motivation is worth naming, because it predicts which features actually matter. Separation of funds is the entry requirement. After that, the differentiators are how many people can spend, how much of the bookkeeping happens automatically, and who carries the obligation if things go badly. Those three questions map onto three different product categories, and the phrase "business card" covers all of them without distinguishing between any.

This page maps the intent onto the categories. For the credit-specific end of the space, Brex Business Credit Card is the detailed treatment; for company-liable programs with centralised administration, Brex Corporate Card covers the mechanics. This site is an independent reference, not a provider: no rates, fees, rewards, limits or eligibility rules appear here, and there is nothing to apply for.

Business card

Any card intended for company purchases rather than personal ones. A statement of purpose rather than a defined product structure.

Separation of funds

Keeping company transactions out of personal accounts, which is the baseline reason the category exists.

Sole trader account

An arrangement where the business and the individual are not legally distinct, which changes what "business" means on the card.

Program

The point at which a card stops being one credential and becomes an administered set of them with rules and owners.

Four distinct structures compete for the same search term. They differ in who is liable, how the balance settles, and how many people can realistically be given access.

The jump between the third and fourth rows is much larger than it appears. Supplementary cards on a business card account are usually a convenience feature: extra credentials on someone else’s account. A corporate program treats issuance as a first-class function, with role templates, budget linkage, delegated administration and scheduled access review. Companies frequently outgrow supplementary cards without noticing, and then spend a year making a convenience feature do a program’s job.

The fastest way to narrow the field is to answer three questions honestly. Most people can do it in under a minute, and the answers eliminate at least two of the four structures.

1. How many people will need to spend in a year?

   One or two points to a business card. Five or more, especially across different teams, points to a program with real issuance capability. Answer for twelve months from now, not for today.

2. Does the balance need to be carried?

   If the full amount can clear every cycle, charge settlement removes financing cost. If working capital is genuinely seasonal, a revolving facility has a purpose. See Brex Credit Card.

3. Is a personal guarantee acceptable?

   If not, the field narrows quickly to company-liable arrangements. If it is, establish in writing what triggers the guarantee and how it is released.

A fourth question is worth adding for anyone whose spending is heavily software-based: does the structure support virtual issuance? For a company running thirty subscriptions, a single credential entered into thirty billing pages is a reconciliation liability and a security one. Virtual cards explains why one card per vendor changes both problems at once.

Company spending has a distinctive shape, and understanding the shape is what makes it manageable regardless of which structure you chose. It clusters into a handful of recurring categories with very different characteristics.

Notice that each category implies a different instrument and a different control. That is the whole argument for structures that can issue more than one card: not that a company needs many cards, but that spending patterns are heterogeneous and a single credential forces every pattern through the same rules. Business expenses works through the categories from the accounting side.

Control capability varies enormously across the four structures, and it is the dimension least visible when comparing them. A card either evaluates your policy at the moment of payment or it does not, and no amount of reporting afterwards substitutes for that.

The honest position is that a small company with two cardholders may need none of the right-hand column, and buying administrative machinery it will not use is its own kind of waste. The signal to move is not size in itself but the moment somebody starts maintaining a spreadsheet to keep track of who spent what. Spending controls and card limits cover the design once you get there.

Giving employees the ability to spend is the point at which every business card decision compounds. Before it, a card is a payment method. After it, the card is a delegation mechanism, and delegation needs boundaries that do not depend on anyone remembering them.

• Every instrument has one named owner, so no transaction is orphaned at posting
• Limits are set from a role template rather than negotiated individually
• A single documented receipt threshold applies to everyone, without exceptions by seniority
• There is a fast escalation route for legitimate purchases above a ceiling
• Cancellation sits in the offboarding checklist alongside system deprovisioning

The alternative model — employees pay personally and claim reimbursement — looks cheaper because it requires no card infrastructure. In practice it moves the cost onto individuals, delays evidence until claim time, and quietly disadvantages anyone without spare personal capacity. Employee cards sets out what a properly scoped alternative looks like, and employee spending covers the policy side.

Whatever structure you choose, every transaction eventually has to become an accounting entry with a category, a purpose and evidence attached. The structure decides how much of that work is done by rules and how much lands on a person during close week.

• Capture — the transaction posts with amount, merchant descriptor and category code
• Attribute — the instrument identifies the owner, and ideally the vendor and purpose too
• Document — a receipt is attached, forwarded on the day or matched automatically
• Code — cost centre, project and tax treatment are applied, by rule where possible
• Reconcile — the item is matched to the ledger and the period closes on schedule

The attribute step is where structural choices pay off most visibly. On a shared card, attribution is a memory exercise; on a vendor-locked virtual credential it is automatic. That single difference accounts for a large share of the perceived difference in administrative burden between a basic business card and a proper program. See expense management and expense automation.

There is no headcount threshold that applies universally, but there are reliable symptoms. When two or three of these are true, the business card structure has stopped fitting.

If those symptoms are familiar, the comparison to read next is corporate card vs business card, which sets the two structures against explicit criteria. If the question is more about settlement than administration, corporate card vs credit card is the better fit. And for company-stage context, growing businesses and small business cover the transition from opposite ends.
