Why this matters more than most people think.
Taking payment online is not just about convenience. It is about trust signals, speed, and cash flow. When someone can pay you at 10pm on a Tuesday, from their phone, you get the money before they have a chance to think twice. When they have to remember your sort code and reference number, you are relying on their admin skills — which, honestly, are not always great.
I have seen tradespeople in Deal and Sandwich lose weeks of cash flow simply because they sent a PDF invoice by email and then waited. The fix is not chasing harder; it is making payment frictionless. That starts with choosing the right tool.
The three options most small businesses are actually choosing between.
Ignore the noise about dozens of payment platforms. For a Kent service business — a plumber, a bookkeeper, a photographer, a cleaning company — the real choice is between Stripe, SumUp, and PayPal. They are not interchangeable, and picking the wrong one has real costs.
Stripe is the one I recommend most often for businesses that have, or plan to have, a proper website. The fees are 1.5% plus 20p per transaction for UK cards (European cards run a little higher), and there is no monthly charge unless you move to a paid plan. It integrates with almost everything — WooCommerce, Squarespace, Notion, custom-built sites — and the payouts hit your UK bank account within two business days. HMRC-wise, the transaction records are clear and exportable, which your accountant will thank you for.
SumUp is better if you take payment face-to-face as well as online. Their card reader costs around £39 one-off, the transaction rate is 1.69% flat, and the online payment links work cleanly without needing a website at all. I have set it up for a Canterbury-based music teacher who does lessons at people's homes — she sends a payment link over WhatsApp before each session. Simple, professional, done.
PayPal is the one people default to because they already have an account, not because it is the best choice. Fees for UK businesses receiving payments run to around 2.9% plus 30p — noticeably higher than Stripe — and the checkout experience on mobile is clunkier than it used to be. It is not terrible, but if you are starting fresh, I would not choose it as your primary payment tool in 2026. The one exception is if your customers specifically ask for it, which does still happen with older demographics.
What to check before you sign up for anything.
A few things trip people up that are worth sorting before you create an account. First, know whether you are operating as a sole trader or a limited company — both can use any of the tools above, but the name on the account and the bank account it pays into should match. If you are a sole trader trading under a business name, that is fine, but the underlying account will be in your personal name with HMRC and Companies House records behind it if anyone checks.
Second, have a UK business bank account ready. Stripe will not pay out to a personal current account in all setups, and mixing business and personal money makes your self-assessment a misery. If you do not have a business account yet, Starling and Monzo Business are both free to open and work well with all three platforms. Tide is another option that a few of my clients in Folkestone use without complaints.
Third, check your trading name. If your website, your invoices, and your payment screen all say different things, customers lose confidence. The name on the payment page should match the name they Googled. It sounds obvious, but I have seen it go wrong more than once.
Payment links versus a full checkout.
Not every business needs a full e-commerce checkout. A lot of the service businesses I work with just need to send a payment request and get paid. Every platform above supports payment links — a URL you send by email or WhatsApp that takes the customer straight to a payment screen, no website required.
Stripe's payment links are clean and brandable. SumUp's are fine. Both arrive in the customer's browser looking professional, which matters more than people expect — a clunky-looking payment screen does create hesitation, especially for higher-value transactions.
If you do want a proper checkout embedded in a website — say you sell a fixed-price service package and want people to be able to buy without talking to you first — that is a slightly different build. Stripe handles it well via their hosted checkout, and if your site is on WordPress or WooCommerce I can wire it up so the payment, the confirmation email, and the booking notification all happen automatically. That is the point where you start saving real time.
Recurring payments and deposits.
If you take retainers, run a subscription service, or regularly ask for a deposit before work starts, this is where Stripe genuinely earns its keep. Their recurring billing (via something called Stripe Billing or through a tool like GoCardless for direct debit) handles the whole cycle without you having to chase. GoCardless in particular is worth knowing about for UK businesses taking regular direct debits — the fees are around 1% capped at £4 per transaction, and it plugs into Xero and QuickBooks cleanly.
For deposits specifically, I have seen a lot of service businesses in Kent lose out when a client cancels last-minute and there is nothing in writing and no deposit held. Taking a 25% or 50% deposit via a payment link at the point of booking changes that dynamic immediately. It also filters out the tyre-kickers, which is a side benefit most people underestimate.
What HMRC actually needs to see.
This is the bit people worry about unnecessarily. All three platforms produce transaction records you can download — Stripe's are particularly clean in CSV format. For self-assessment as a sole trader, you need to be able to show total income received and, where relevant, platform fees paid. Both figure into your accounts. Your accountant, or even just a decent spreadsheet, can handle this without a problem.
If you are VAT-registered — threshold is currently £90,000 turnover in a 12-month rolling period — you will need to be a bit more careful about how the payment records map to your VAT returns. Stripe's dashboard makes this manageable, but it is worth discussing with an accountant before you cross that threshold rather than after.
The five-minute setup most people skip.
Whichever platform you choose, do these things before you send your first payment link. Add your logo to the payment screen — it takes about two minutes in Stripe's dashboard and immediately makes the experience look intentional. Set up an automated receipt email with your trading name and a contact number, so customers have something to refer back to. And test the whole flow yourself — on your phone, on a desktop, on a different browser — before you send it to a real customer. The number of times I have seen a payment link go out that redirects to an error page because nobody tested it is genuinely embarrassing.
If you are on Stripe, also turn on Stripe Radar's basic fraud protection while you are in there. It costs nothing on the standard plan and quietly catches a meaningful number of dodgy transactions before they hit your account.
