Best Card Machine for Freelancers & Consultants UK
Updated July 2026
Exclusive Rates From as Low as 0.26%
Freelancers and independent consultants face a payment challenge most high-street businesses do not: clients expect a professional invoice or card payment option, yet you may only take a handful of payments each month. Paying a fixed monthly terminal rental for 18 months makes no sense when you bill six clients a quarter. You need something low-cost, portable, and ready to take a card in a client's office, a coffee shop, or at your desk.
Key Takeaways
- ✓ Pay-as-you-go card readers from SumUp and Square charge no monthly fee, so a quiet month costs you nothing beyond the transaction rate.
- ✓ SumUp charges 1.69% per transaction with no monthly fee, making it one of the cheapest flat-rate options for low-volume freelancers in 2026.
- ✓ Square's free plan starts at 1.75% per in-person transaction and includes invoicing software, which removes the need for a separate billing tool.
- ✓ Zettle by PayPal charges 1.75% per transaction with no monthly contract and settles funds to your bank account by the next working day.
- ✓ Stripe Terminal suits freelancers who already invoice online and want a single platform for both card-present and card-not-present payments.
Who Is This Page For?
This page is written for UK-based freelancers, independent consultants, contractors, and sole traders who take card payments in person, at a client site, or occasionally at an event. It is equally relevant if you mix in-person payments with online invoicing. If you process more than £30,000 a month, a merchant account through a traditional acquirer may offer lower rates and you should read our guide to Worldpay for businesses instead.
Key Facts: What to Expect from a Freelancer Card Reader

| Contract length | No contract or rolling monthly |
| Monthly fee | £0 to £19 depending on plan |
| Transaction fee | 1.69% to 1.75% for most flat-rate providers |
| Settlement speed | Next working day in most cases |
| FCA regulation | All providers listed here are FCA-authorised |
What Does a Freelancer Need from a Card Machine?
Battery life and portability matter above almost everything else. If you visit clients at their premises, a card reader that dies after 20 transactions is a problem. SumUp's Air reader claims up to 500 transactions per charge. Zettle's card reader 2 is similarly rated and weighs just 59 grams, which means it fits in a jacket pocket without bulk.
Low or zero fixed costs are equally important. A freelance graphic designer billing four clients a month cannot justify a £25-per-month terminal rental that eats into margins before a single transaction is processed. Pay-as-you-go pricing, where you only pay a percentage on actual sales, is almost always the better structure until you exceed around £5,000 in monthly card turnover. Above that volume, a provider with a small monthly fee but a lower transaction rate can start to save money.
Fee Comparison: Best Card Machines for Freelancers
| Provider | Transaction Fee | Monthly Cost | Verdict |
|---|---|---|---|
| SumUp | 1.69% per in-person transaction | £0 (no monthly fee) | Cheapest flat rate for low-volume freelancers |
| Square | 1.75% per in-person transaction | £0 (free plan) or £19/month for Plus | Best if you also need free invoicing software |
| Zettle by PayPal | 1.75% per in-person transaction | £0 (no monthly fee) | Good choice if you already use PayPal for invoices |
| Stripe Terminal | 1.5% + 0p for UK cards (card-present) | £0 (no monthly fee) | Best for tech-confident freelancers who bill online too |
Our Top Pick for Freelancers: SumUp
SumUp is the strongest all-round choice for most UK freelancers in 2026. The transaction rate of 1.69% per in-person card payment is the lowest flat rate among the major pay-as-you-go providers. On £3,000 of monthly card turnover, that is £50.70 in fees, compared to £52.50 with Square or Zettle at 1.75%. The Air card reader costs a one-off £39 plus VAT. There is no monthly fee, no contract, and no minimum turnover requirement.
SumUp also offers a free business account with a UK sort code and account number, so client payments settle directly into that account by the next business morning without needing a separate bank. The companion app handles basic sales reporting and works on both iOS and Android. One honest weakness: SumUp's invoicing feature is more limited than Square's, and if professional-looking client invoices are central to your workflow, that gap matters.

Runner-Up Options
Square: Best for Freelancers Who Need Free Invoicing
Square's transaction rate of 1.75% is 0.06 percentage points higher than SumUp, but the platform includes a fully featured invoicing tool at no extra cost. You can send professional invoices by email, let clients pay by card online, and reconcile everything in one place. For a freelance consultant who sends ten invoices a month, removing a separate invoicing subscription that might cost £10 to £15 a month easily offsets the marginally higher transaction fee. The Square Reader costs £19 plus VAT. Settlement is typically the next business day. One limitation: Square's customer phone support is not available 24 hours a day, which can be frustrating if a payment fails before an important client meeting.

Zettle by PayPal: Best for Freelancers Already Using PayPal
Zettle charges 1.75% per in-person transaction and has no monthly fee or contract. Its main advantage for freelancers is the tight integration with PayPal. If you already invoice international clients through PayPal, having in-person card payments feed into the same account reduces admin. The Zettle Reader 2 is compact and handles contactless, chip and PIN, and Apple Pay or Google Pay. One notable drawback is that accessing funds in a PayPal balance is not the same as a standard UK bank account, and transfers out can occasionally take one to three business days depending on your account status.

Frequently Asked Questions
What is the cheapest card machine for a freelancer in the UK?
SumUp is the cheapest option for most UK freelancers in 2026. The Air reader costs £39 plus VAT as a one-off purchase, there is no monthly fee, and the transaction rate is 1.69% per in-person card payment. On £1,000 of monthly card sales, total fees would be around £16.90 with no other charges.
Do I need a card machine if I only take occasional payments?
No, you do not need a physical card machine for occasional payments. Providers like Square and SumUp also let you send a payment link by email or text, which the client pays online using their card. There is no hardware needed and the fee is typically around 2.5% per link transaction, which is higher than in-person rates but reasonable for one-off or rare payments.
Can a freelancer get a card machine without a business bank account?
Yes, most pay-as-you-go providers do not require a dedicated business bank account to sign up. SumUp, Square, and Zettle will all accept a personal UK bank account for settlement. SumUp goes further by offering a free built-in business account with its own sort code and account number, so you can keep freelance income fully separate from day one.
How quickly will I receive the money after a client pays by card?
For most freelancers using SumUp, Square, or Zettle, funds arrive in your bank account the next working day. If a client pays on a Friday, you typically see the money on Monday morning. Some providers offer same-day or instant payouts for an extra fee, usually around 1% of the transfer amount.
Is a card machine better than invoicing for freelancers?
A card machine works better when you meet clients in person and want payment on the spot. Invoicing works better for remote or project-based work where payment follows at an agreed date. Many freelancers use both: Square and SumUp both include invoice-sending tools alongside their card readers, so you do not have to choose one or the other.
