Business credit card guide: how they work and what to check

What is a business credit card?

A business credit card is a line of credit for business spending. The provider agrees a credit limit, you pay for things with the card, and you get a statement showing what you owe. You then pay some or all of that balance back. If you don't clear it in full by the due date, the provider usually charges interest on what's left, as set out in your agreement.

It's different from a loan. With a loan you get a lump sum and repay it on a fixed schedule. With a business credit card you borrow only what you spend, and the amount you owe goes up and down from month to month.

Common reasons small companies use one:

• paying for stock, software subscriptions or travel before a customer pays you
• keeping business spending separate from personal cards
• giving team members their own cards with spending limits
• collecting receipts and transactions in one feed for your bookkeeping
• earning points or cashback on spending you'd make anyway

Business credit card vs debit card vs charge card

Most business bank accounts come with a debit card. That card spends money you already have. A business credit card spends the provider's money, which you repay later. A charge card sits in between: you usually have to pay the whole balance each month.

Many businesses use both: the debit card for day-to-day costs and a business credit card for larger or irregular purchases. Some suppliers can still add a surcharge when you pay with a commercial card, capped at their cost of taking the payment, according to government guidance on payment surcharges. So check the price before you pay.

How a month on a business credit card works

1. 1

   You spend

   Each purchase reduces your available credit. Some providers let you set separate limits for each team card.

2. 2

   The statement arrives

   It shows everything spent in the period, the balance, the minimum payment and the date it's due.

3. 3

   You choose how much to repay

   Paying the full balance by the due date usually means no interest on purchases. Paying only part leaves a balance that the provider charges interest on.

4. 4

   Your limit frees up

   Whatever you repay becomes available to spend again. That's why a business credit card can feel like a rolling buffer.

The terms that matter most are the ones in your own agreement: the interest you'd pay on a balance, how cash withdrawals are treated, any late payment fee, and how the minimum payment is worked out. Read them before you accept, and ask the provider if anything isn't clear. We don't quote rates here because they vary by applicant and change over time.

A simple habit helps: set up an automatic payment from your business account for the full statement balance. Your business credit card then works like a 30-day delay on paying, rather than a loan.

Personal guarantees: who is really responsible?

A limited company is a separate legal person, so its debts are normally its own. A personal guarantee changes that for the debt it covers. If you sign one, you agree to pay the debt yourself if the company can't.

Many providers ask for one on a business credit card for a small company. Capital on Tap, for example, says in its help centre that the main account holder gives a personal guarantee and that "if the business is unable to pay its debts, you will be required to pay them". It also says you stay responsible even if the business closes or you stop being a director.

Before you sign, think about:

• the worst case: how much you could owe personally if the limit were fully used
• whether your fellow directors are giving guarantees too
• what happens if you leave the company or sell your shares
• whether applying affects your personal credit file (some providers run a soft search on you and a hard search on the business)

If you're not sure what a guarantee means for you, ask a solicitor or accountant. Our guide to sole trader or limited company explains how limited liability works more generally.

Rewards and fees on a business credit card

Rewards are the part providers advertise most. They tend to come as points you can swap for vouchers or travel, or as cashback on spending. A welcome bonus may be paid after your first purchase or after you reach a spending target.

Rewards are only worth having if you'd make the spending anyway and clear the balance. Interest on a balance you carry over can quickly outweigh points earned.

When we checked Capital on Tap's own site, its free plan listed no annual fee, no foreign exchange fees and unlimited free employee cards, with credit limits of up to £250,000. Your own limit depends on the provider's checks.

Who can get a business credit card?

Each provider sets its own rules. They usually look at your business type, how long it's been trading, its turnover, and the credit history of the business and its directors.

Some cards are only for companies. Capital on Tap's eligibility page, for example, says the business must be a private limited company or LLP based in the UK, with turnover of at least £24,000 a year, and that you must be an active director or own at least 25% of it. It also asks for no unsatisfied CCJs against you or the business in the last 12 months.

If you're a sole trader, fewer options may be open to you, and you're personally responsible for business debts anyway. Some sole traders use a separate personal credit card only for business spending. That can work, but check the card's terms allow it and keep the receipts.

Using a card alongside your business bank account

A business credit card doesn't replace a business current account. You still need an account to get paid, pay bills and repay the card each month. In practice the two work as a pair:

• Repay from the account: set up a payment for the full statement balance from your business account.
• Feed both into your books: link both to your accounting software so every purchase is matched with a receipt. Our bookkeeping guide covers the record-keeping rules.
• Keep a buffer: don't rely on the card for money you'll need to repay at once.

If you haven't chosen an account yet, you can compare business bank accounts side by side. Some account providers, such as Tide, also offer access to business loans from a panel of lenders, subject to status; our Tide review covers what's included. A business credit card is one of several ways to borrow; our small business funding guide looks at the others.
