Business credit card or debit card: how to choose

Most businesses use both credit cards and debit cards as part of their day-to-day operations. The tricky bit is deciding which one to reach for when you’re actually making a payment.

The short version: a business debit card spends money you already have, drawn straight from your business current account the moment you tap. A business credit card spends borrowed money against a limit, and you settle up later, with an interest-free window if you clear the balance in full. That timing gap is the whole difference, and everything else follows from it.

Use the debit card for day-to-day costs you can comfortably cover today. Use the credit card for spending where the gap between paying out and getting paid in actually costs you something, and where earning cashback on money you were going to spend anyway is worth having.

Below, what each card does, the five differences that change decisions in practice, and where credit cards catch people out.

How each card works

Business debit cards

A business debit card is attached to your business current account. Spend on it and the money leaves immediately. If the balance isn't there, the payment fails, unless you have an arranged overdraft.

You get one when you open the account, with no separate application, no credit assessment and usually no fee beyond whatever your bank charges for the account itself. Cash withdrawals work normally. Most providers will issue additional cards for staff, though what you can control on them varies a lot.

The appeal is simplicity and hard limits. You cannot spend money you don't have, which for some businesses is the entire point.

Business credit cards

A business credit card gives you a limit to spend against, separate from your bank balance. You get a statement, and you either clear it in full or carry a balance and pay interest on it.

Most business credit cards give you an interest-free grace period between making a purchase and the payment being due, which effectively buys you time. The Funding Circle Cashback business credit card offers up to 42 days interest-free credit on that basis.

Applying is a separate process from your banking, with eligibility criteria and a credit assessment. Cards are usually issued to a limited company rather than an individual, and most UK providers ask a director for a personal guarantee.

Five differences that matter in practice

When the money leaves

• Debit: immediately. 

• Credit: up to several weeks later, depending on where in your billing cycle the purchase falls.

For a business paid on 30 or 60 day terms, that window is genuinely useful. You buy the stock, sell it, get paid, then settle the card. Do the same on debit and your working capital is tied up the whole time. You can learn about this in more depth in our guide to how business credit cards can help manage cash flow.

Rewards

Business debit cards very rarely pay anything. Business credit cards often do, most commonly cashback or points.

For an example, take your annual card spend and apply the cashback rate. If your business puts a meaningful volume through a card each year, the difference between 0% and 1% is not trivial. If your card spend is small, it barely registers, and you should weigh the other factors instead.

Whether it builds a credit profile

Debit card activity doesn't build anything, because there's no credit involved.

A business credit card used well can help establish a build commercial credit history, which matters if you expect to borrow later. Lenders and credit reference agencies look at how a business handles credit it already has. Used badly, the same mechanism works against you, since late payments and persistent balances are also visible.

What protection you get

Chargeback, which is a card scheme rule rather than a law, exists for both credit and debit card purchases. It's the route for non-delivery, faulty goods and fraud on either card type, and it's what most business disputes will actually run through. 

Legal protections vary by product, by provider and by circumstance. This is a general summary rather than legal advice, and for anything material it's worth taking advice from a qualified professional.

Controlling across a team

Both card types can be issued to staff. What differs is what you can do with them.

Business credit cards from card-focused providers tend to offer per-card spend limits, real-time visibility and free additional cards. Bank-issued debit cards vary widely, and controls are often thinner or come with a fee. If you have people spending in the field, this difference is worth more attention than the headline features. Our guide to business expense cards for employees goes through the options.

The comparison

What to put on which card

Debit suits small everyday costs, anything you'd rather see leave the account immediately, spend by people you'd prefer not to give a credit limit to, and cash withdrawals.

Credit suits recurring supplier payments, stock and inventory, equipment, subscriptions, travel and fuel, and anything large enough that the timing gap and the cashback both matter. If you spend abroad, a card with no foreign exchange fees usually belongs here too.

The practical version for most businesses is: put as much predictable spend as possible on the credit card, clear it in full every month by direct debit, and keep the debit card for the rest.

What are the risks of a credit card?

Interest can wipe out rewards 

Cashback on a business credit card runs at a percent or two. Interest on a carried balance runs at many times that. The rewards are only real if you clear the balance. If you're carrying one regularly, that's a cash flow issue to address rather than a card feature to optimise. Our guide to cash flow is a better starting point than a new card.

Personal credit risks 

Most UK business credit cards require a director to guarantee the debt personally. It's normally only enforced if the business defaults, but it's a binding commitment and worth taking independent legal advice on before signing.

Fees vary more than headline rates suggest

Annual fees, cash withdrawal charges, foreign exchange fees, late payment fees and charges for additional cards all differ between providers and change over time. Compare the full cost against how your business actually spends, and check current terms directly with the provider. Our guide to business credit card rates, fees and charges covers what to look for.

How card spending, cashback and rewards are treated in your accounts depends on how your business is structured. Speak to your accountant or a qualified tax adviser about your own position.

What to do if a business credit card isn't available to you

Not every business will qualify, and it's better to know where you stand than to collect declined applications.

Most UK business credit card providers ask for an incorporated business, and many set a minimum trading period, a minimum turnover, or both. Sole traders have fewer options, though some providers do accept them. Businesses in their first months of trading will find most doors closed.

If that's your position, the business debit card that came with your account is doing a real job. Build a trading history, keep your accounts clean, and revisit the question when you meet the criteria. Whether your company is ready for a business credit card can give you more information.

Frequently asked questions

Can my business have both a credit card and a debit card?

Yes, and most do. The debit card comes with your business current account and the business credit card is a separate application. Running both lets you match the card to the purchase rather than the other way round.

Does a business debit card build my business credit score?

No. There's no borrowing involved, so there's nothing to report. A business credit card used responsibly can help build a commercial credit history, which may matter when you come to borrow.

Which card is safer if my details get stolen?

Both carry fraud protection, and chargeback applies to both. The practical difference is whose money is missing while it's sorted out. On a debit card the funds have already left your account. On a credit card the disputed amount sits against your limit instead.
