Business Credit Card Guide

Almost every difficulty people have with business cards comes from four words being used as if they were interchangeable: business, corporate, credit and charge.

They are not interchangeable. Two of them describe who the card belongs to and who administers it — business and corporate. The other two describe how the money behaves — credit and charge. Any real card sits at an intersection of the two axes, which is why a phrase like "business credit card" tells you two facts and leaves several unstated.

This guide works through the axes in order. Where a topic has a dedicated page or a full comparison elsewhere on this site, the guide summarises and links out — see the cards hub for the term-level pages and the comparisons hub for the decision frameworks.

Business card

Any card intended for company purchases. Says nothing about liability or settlement.

Corporate card

A card model where the account sits with the company and issuance is centralised.

Credit card

A facility where a balance may be carried between cycles.

Charge card

A card where the balance is settled in full each cycle by design.

Personal guarantee

A commitment by an individual to cover the company’s obligation if the company does not.

A business credit card is a revolving credit facility opened for business purchases. Two properties define it. First, it is credit: the issuer extends a line and the balance may be carried from one cycle to the next rather than cleared. Second, it is for business use: the purchases are company purchases, and the transaction data is generally structured for business accounting rather than personal budgeting.

The part that surprises people is the third property, which is not in the name at all: who is being assessed. On many small-business cards, the applying individual is assessed alongside — or instead of — the company, and a personal guarantee is part of the arrangement. That is not a flaw; for a company with little trading history it may be the only route to a card at all. But it is a materially different commitment from a company-liability card, and it is the reason liability is the first question to ask about any business card.

People searching for a brex business credit card or brex business credit cards are usually trying to fill in this table for one product. This project cannot fill it in for you — we publish no commercial terms — but the business credit card page explains the category, and the brex business card page covers the vaguer phrasing people reach for when they are not yet sure which of the four questions matters most to them.

This is the settlement axis, and it is the difference most often glossed over. A credit card lets a balance persist; a charge card is designed so it does not. Everything else follows.

The practical consequence is behavioural. On a charge structure, overspending shows up immediately as a cash problem at the end of the cycle, which is uncomfortable but honest. On a credit structure, overspending can be deferred, which is comfortable and can hide a trend for several cycles. Neither is better in the abstract; they suit different cash positions.

The full treatment, including how to decide, is on the business credit card vs charge card comparison. What belongs in this guide is the warning: the word "card" on a marketing page tells you nothing about settlement, so read it from the agreement rather than inferring it.

This is the ownership-and-administration axis. "Business card" describes intent — the card is for company purchases. "Corporate card" describes structure — the account sits with the company and cards are issued and closed centrally under policy.

For a two-person company the distinction barely matters, because the applicant, the administrator and the only cardholder are the same person. The distinction starts to matter the moment a third person needs to buy something. At that point a business card without central administration turns into a shared credential, an informal reimbursement habit, or a card handed around — all three of which are worse than either alternative.

A corporate structure answers the "third person" problem by making issuance cheap and revocation instant. That is why the corporate card guide spends most of its length on program mechanics rather than on the card, and why employee cards is a topic in its own right.

The side-by-side version, including which structure suits which company shape, is on the corporate card vs business card comparison. If you want the other pairing — the settlement-versus-ownership confusion — that is corporate card vs credit card.

The card arrangement that works for a founding team is usually the wrong one by the time there are a few dozen people, and the failure is gradual enough to be easy to miss. It shows up as symptoms rather than as a decision point.

• More than one person knows the card number, or a card is physically shared
• Employees are paying for work items personally and claiming them back
• Nobody can name every recurring subscription on the account
• Limit increase requests arrive by message and are granted permanently
• Month-end involves asking people what a charge was for
• A departure means someone has to remember which cards to close

Each symptom maps to a control that does not exist yet. Shared credentials mean issuance is too expensive, so people work around it. Personal spending followed by reimbursement means limits are too tight or cards are too few. Unknown subscriptions mean no per-vendor attribution, which single-vendor virtual cards solve almost entirely — see virtual cards.

The stage-specific pages go further: growing businesses for the middle of that table, small business for the lighter end, and the startup card guide for companies where software is most of the spend.

Card marketing is designed around the two attributes that are easiest to make attractive and least likely to matter in a year: the headline reward and the introductory term. The attributes that determine whether the card works for a company are duller and usually further down the page.

Rewards are not irrelevant, but they are a rate applied to spend you were going to make anyway, whereas control and data quality change how much work the finance function has to do every month. Weighting them the other way round is the most common evaluation error. The brex value page discusses how to evaluate a card platform’s value claim without relying on the claim itself.
