Should small businesses accept card payments on invoices despite the fees

Offering clients a way to pay your invoices online with a credit or debit card can feel like a modern necessity. It's fast, convenient, and what many customers have come to expect. However, that convenience comes at a cost – processing fees that can eat into your profit margins on every single transaction. For UK small businesses, freelancers, and consultancies, this creates a classic dilemma: is the benefit of getting paid faster worth giving up a percentage of your hard-earned revenue?

This article breaks down the pros and cons of accepting card payments on your invoices. We'll explore the real costs involved, weigh them against the impact on your cash flow, examine the alternatives, and provide a practical framework to help you decide on the right payment strategy for your business.

The Core Dilemma: Faster Cash Flow vs. Processing Costs

At its heart, the decision to accept card payments is a trade-off. On one hand, you have the powerful lure of improved cash flow. A "Pay Now" button on an invoice, powered by a service like Stripe or PayPal, removes friction. Your client can settle their bill in under a minute with a card they have in their wallet, rather than scheduling a Bacs payment or, heaven forbid, posting a cheque. This speed can be critical for small businesses where a healthy cash balance is the lifeblood of the operation.

On the other hand, every card payment incurs a fee. Typically, this is a combination of a small fixed amount (e.g., 20p) plus a percentage of the total invoice value (e.g., 1.5% - 2.9%). While this might seem small on an individual invoice, it adds up. A 1.5% fee on £50,000 of annual turnover is £750 straight off your bottom line. That's money that could be spent on marketing, software, or your own salary. The central question is whether the benefits of speed and convenience outweigh this direct financial cost.

The Case for Accepting Card Payments

For many businesses, the advantages of offering card payments are compelling and go beyond just getting paid a few days earlier.

Unquestionably Faster Payments and Improved Cash Flow

This is the number one reason businesses adopt card payments. When a client has to manually log into their online banking, set you up as a new payee, and transfer the funds, it creates multiple points of delay. They might put it off until later, forget, or make a mistake with the payment reference.

A card payment is an impulse action. The client opens the invoice, clicks the button, and enters their details. The payment is confirmed instantly. This can slash your average debtor days – the time it takes to get paid – from 30, 60, or even 90 days down to just a few. This predictability makes forecasting and managing your business finances significantly easier.

A Better, More Professional Customer Experience

In 2024, convenience is king. Your clients are consumers in their daily lives, accustomed to one-click checkouts and seamless digital payments. Forcing them into a cumbersome Bacs payment process can feel outdated and create a poor final impression of your service.

Offering a simple card payment option shows that you are professional, modern, and easy to do business with. This small touch can enhance your brand perception and may even be a deciding factor for a client choosing between you and a competitor. It removes a potential point of friction and ends the project on a positive, efficient note.

Reduced Administrative Burden

Chasing down missing payment references from Bacs transfers is a common headache for any accounts department or sole trader. When a payment appears in your bank account with a vague reference like "INVOICE" or the client's company name, you have to play detective to match it to the correct bill.

Card payments, when integrated with your accounting software, solve this problem. The payment is automatically logged against the specific invoice it relates to. This drastically reduces the time spent on manual reconciliation, freeing you or your team to focus on more valuable work.

Enhanced Security and Trust

Using an established, reputable payment gateway like Stripe, PayPal, or Worldpay provides a layer of security and trust for both you and your client. These platforms are PCI DSS compliant, meaning they adhere to strict security standards for handling card data. Your client can be confident their details are secure, and you avoid the significant risk and liability of handling or storing sensitive card information yourself.

The Downsides and Costs of Card Payments

While the benefits are clear, the drawbacks are very real and need to be carefully considered. It's not just about the headline fee.

The Obvious Cost: Transaction Fees

This is the most significant barrier. Payment processing fees directly reduce your revenue. A typical fee structure in the UK looks something like this:

• For UK consumer debit/credit cards: 1.5% + 20p
• For European cards: 2.5% + 20p
• For all other international cards: 3.25% + 20p

Let's put that into perspective. If you issue a £1,000 invoice to a UK client, you would pay a fee of (£1,000 * 0.015) + £0.20 = £15.20. If your profit margin on that project was 10% (£100), that fee has just consumed over 15% of your profit. You need to be sure that your pricing can absorb this cost without making the work unprofitable.

The Risk of Chargebacks

A chargeback (or "dispute") occurs when a customer disputes a transaction with their card issuer. They might claim the service wasn't delivered, the product was faulty, or the charge was fraudulent. If the card issuer sides with the customer, the funds are forcibly returned from your account.

Not only do you lose the entire invoice amount, but you will also be charged a non-refundable dispute fee by your payment processor, often around £15-£20, even if you successfully challenge the dispute. While rare in B2B transactions, chargebacks are a real risk, particularly when dealing with new or unknown clients.

Delayed Payouts (Settlement Times)

While the client's payment is "instant," the money doesn't appear in your bank account instantly. Payment processors have settlement periods, which is the time they take to bundle up your transactions and transfer them to you.

This can range from 2 business days to 7 business days or more. It's still almost always faster than waiting for a 30-day invoice to be paid by Bacs, but it's a crucial detail to be aware of. You are not getting the cash on the same day the client pays.

You Can't Legally Pass on the Fee (Surcharging is Banned)

A common question is, "Can't I just add the card fee to the customer's invoice?" In the UK, the answer is a firm no for most transactions. The Consumer Rights (Payment Surcharges) Regulations 2012 banned surcharging for consumer credit and debit card payments.

While the ban doesn't technically apply to purely commercial B2B cards, adding a "card processing fee" at checkout is seen as extremely poor practice. It creates a negative customer experience and complicates your invoicing. The correct approach is to treat processing fees as a standard cost of doing business and factor them into your overall pricing structure, just as you would with rent, software, or insurance.

A Breakdown of Common UK Payment Options

The market for payment processing is competitive. Here’s a simplified comparison of some popular options for UK small businesses. Note that fees are indicative and you should always check the provider’s latest pricing.

Payment Method	Typical Fee Structure (UK Cards)	Payout Time	Best For
Stripe	1.5% + 20p	2-3 business days	Businesses needing a flexible, powerful API and easy integration with accounting software. Great for one-off and recurring payments.
PayPal	1.2% + 30p (Commercial rate)	2-3 business days	Businesses wanting a widely recognised and trusted name. Good for freelancers and international clients, but fees can be higher for some transactions.
GoCardless	1% + 20p (capped at £4)	3-5 business days	Recurring revenue and B2B invoices. Pulls funds via Direct Debit rather than card. Not "instant" but gives you control over payment dates.
Open Banking	~0.5% or fixed fee (e.g., 20p-50p)	Instant / Same-day	Forward-thinking businesses wanting the lowest fees. It's a bank-to-bank transfer authorised by the client, with no card details shared.
Bank Transfer	Free	Instant (via Faster Payments)	Businesses wanting to avoid all fees, where clients are disciplined about paying on time and using correct references.

So, Should Your Business Accept Cards? A Decision Framework

There is no single right answer. The best choice depends entirely on your business model, client base, and cash flow needs. Use these questions as a framework to make an informed decision.

1. What Are Your Typical Invoice Values?

The impact of a percentage-based fee is very different on a £50 invoice versus a £15,000 invoice.

• Low-value, high-volume invoices: For businesses like subscription services or those selling many small products, the convenience and automation of card payments often outweigh the small fee on each transaction.
• High-value, low-volume invoices: For consultants, agencies, or builders issuing invoices for thousands of pounds, a 1.5% fee can be substantial (£150 on a £10,000 invoice). In these cases, a free bank transfer is often the preferred and expected method. Offering cards might be a "nice-to-have" for desperate situations, but not the default.

2. Who Are Your Clients?

Understanding your customer's payment habits is key.

• Consumers or Sole Traders (B2C/Micro B2B): These clients are more likely to appreciate and use a card payment option. They are used to paying for things this way and may find a manual bank transfer to be a hassle.
• Large Corporates or Public Sector: These organisations typically have rigid accounts payable departments with their own processes. They will almost always pay via Bacs transfer on 30 or 60-day terms, regardless of whether you offer a card option. A "Pay Now" button on their invoice will likely be ignored.

3. What Are Your Current Debtor Days and Chasing Process?

This is the most critical question. How long does it currently take you to get paid?

If your invoices are consistently paid within 7-14 days via bank transfer, the benefit of adding costly card payments is minimal. Your cash flow is already healthy.

However, if you are constantly fighting to get paid at 45, 60, or 90+ days, card payments could be a game-changer. But it's also a sign that your credit control process might be broken. Before you absorb a 2% fee to get paid, ensure you have a robust system for chasing overdue invoices. Sometimes, the problem isn't the payment method, but a lack of consistent follow-up. Using a tool like InvoiceReminder to automate your chasing emails can often solve a large part of the late payment problem without costing you a percentage of your revenue. A systematic, automated reminder sequence ensures your invoices stay top-of-mind for clients who intend to pay by Bacs.

4. Can Your Profit Margins Absorb the Cost?

Finally, do the maths. Calculate what the total processing fees would have been on your last year's turnover. Can your business comfortably absorb that cost? If your margins are already thin, you may need to slightly increase your prices across the board to accommodate this new cost of doing business. Remember, it's better to build this cost into your pricing from the start than to be surprised by it later.

The Final Verdict: A Hybrid Approach is Often Best

For most UK small businesses, the optimal strategy is not an "all or nothing" approach. It's about offering choice.

The best practice is to offer multiple payment options on your invoices:

1. Bank Transfer: Clearly display your bank details for clients who prefer this free, traditional method. This should be your default for large corporate clients.
2. Card Payment: Include a "Pay Now" button for clients who prioritise convenience and speed, especially for smaller invoice amounts.
3. Open Banking / Direct Debit: Consider these modern alternatives for even lower fees or for managing recurring payments.

By providing choice, you cater to all your clients' preferences, removing any payment friction while still encouraging the use of the most cost-effective methods. The goal is to get paid promptly, and a flexible approach is the surest way to achieve that.

Frequently asked questions

Can I legally charge my UK customers the card processing fee?

No. For payments from consumers using standard credit or debit cards, the practice of surcharging was banned in the UK in 2012. While the rule doesn't explicitly cover B2B commercial card payments, it is considered very poor practice and will likely annoy your clients. You should treat processing fees as a business overhead and factor them into your overall pricing.

Are card payments more secure than bank transfers?

They have different security models. Card payments via gateways like Stripe mean you don't have to handle sensitive card data, which is a major security benefit (PCI compliance). Bank transfers using the UK's Faster Payments system are also extremely secure between the banks. The main risk with bank transfers is human error, such as the client sending money to the wrong account details.

What's the difference between a payment gateway and a payment processor?

A payment gateway is the customer-facing technology that securely captures payment details (e.g., the "Pay Now" form). A payment processor is the service that communicates with the banks to actually move the money. In modern all-in-one solutions like Stripe or PayPal, the company acts as both the gateway and the processor.

How quickly will I receive the money from a card payment?

The payment from your client is authorised instantly, but the money won't be in your bank account instantly. This is known as the "settlement time." For most UK providers, this typically takes between 2 to 7 business days, depending on the provider, your account history, and the type of transaction.

Do I still need to chase invoices if I offer card payments?

Yes, absolutely. Offering a convenient payment method reduces one point of friction, but it doesn't solve the problem of clients who forget to pay, dispute an invoice, or have their own cash flow issues. A systematic credit control process to remind clients about upcoming and overdue invoices remains essential, regardless of the payment methods you offer.

Automate Your Invoice Chasing

Making it easy for clients to pay is one part of the puzzle; reminding them to do so is the other. If late payments are a persistent issue, automating your credit control can save countless hours of manual work and dramatically improve your cash flow. InvoiceReminder connects to your Xero, QuickBooks, Sage, or FreeAgent account and sends scheduled, escalating reminder emails for your unpaid invoices. It helps ensure you get paid faster, without the admin headache. You can configure friendly reminders, firmer follow-ups, and final notices, letting the system handle the difficult job of chasing. The core email reminder service is currently available at no cost. InvoiceReminder is built by the team behind WeCovr, a UK company authorised and regulated by the Financial Conduct Authority for its insurance activities.
