Accepting card payments in person has become essential for UK small businesses, market traders, hairdressers, and event sellers. Cash is no longer king, and customers expect contactless, chip, and mobile payments. If you’re running a market stall, hairdressing salon, or trading at events around the UK, choosing the right card payment provider can boost sales, improve cash flow, and reduce hassle. But with several popular options like SumUp, Zettle, and Square all promising easy-to-use hardware and competitive fees, it’s tricky to know which one suits your business best. In this guide, we’ll break down the key differences on hardware costs, transaction fees, payout speeds, and features — all from a specifically UK perspective.
Understanding Your Business Needs
Before diving into the specifics of SumUp, Zettle, and Square, it’s crucial to understand the nature of your business and how you take payments. Are you a market stall operator selling crafts or food? A hairdresser accepting appointments at a salon? Or an event trader popping up at festivals or fairs across the UK? Each scenario comes with different payment volumes, average transaction sizes, and customer expectations.
For instance, market stalls often have many small transactions daily, so low per-transaction fees and fast payouts matter. Hairdressers may have fewer, higher-value transactions, and might need integrated appointment booking or invoicing features. Event traders tend to require lightweight, portable hardware with reliable offline payment capability.

SumUp: Best for Low Upfront Cost and Simplicity
SumUp is popular across the UK for small traders and sole traders who want a low-cost, no-frills card reader. Its hardware is simple, compact, and highly portable — perfect for market stalls and event traders. The SumUp Air card reader connects to your smartphone or tablet via Bluetooth and accepts chip & PIN, contactless, and Apple/Google Pay.
The key attraction of SumUp is the hardware cost. The card reader is currently priced around £29, with no monthly fees. You just pay a fixed 1.69% fee per transaction, which is competitive for low-volume sellers.
Payouts typically land in your UK bank account within 1-2 business days, which is fairly standard. SumUp’s app is straightforward but doesn’t offer as many advanced features as its competitors, though it does support basic invoicing and product catalogues.
- Hardware cost: £29 (SumUp Air card reader)
- Transaction fee: 1.69% per transaction
- Payout speed: 1-2 business days
- No monthly fees or contracts
- Supports contactless, chip & PIN, mobile wallets
If you process £1,000 in card payments monthly, you’ll pay £16.90 in transaction fees with SumUp. The affordable reader cost and flat-rate fee make it ideal for casual or seasonal sellers.
Zettle by PayPal: Versatile Hardware and UK Market Integration
Zettle, formerly known as iZettle, is owned by PayPal and is a strong contender for UK small businesses wanting more versatile hardware and additional business tools. Their card readers start at £29 for the basic Zettle Reader and go up to £79 for the Zettle Pro, which includes an integrated receipt printer — useful for hairdressers or event traders needing printed receipts.
Zettle charges 1.75% per card transaction in the UK, slightly higher than SumUp, but offers more comprehensive software features. These include product and inventory management, sales reporting, employee management, and integration with PayPal accounts.
Payouts to your UK bank account usually arrive within 1-2 business days, with a PayPal balance option for faster access to funds. Zettle’s app is user-friendly and well-suited for businesses that want to scale or require more detailed sales analytics.
- Hardware cost: £29 (basic reader) to £79 (Pro with printer)
- Transaction fee: 1.75% per transaction
- Payout speed: 1-2 business days, instant to PayPal wallet
- No monthly fees, no contract
- Supports PayPal integration, invoicing, and inventory
If you already use PayPal for online payments, Zettle can unify your payment processing in one dashboard — simplifying bookkeeping and cash flow management.
Square: Best for Integrated Software and Faster Payouts
Square has become a household name for UK SMEs and side hustlers thanks to its powerful combination of hardware and software. The Square Reader for contactless and chip costs £20, the Square Stand (ideal for salons or fixed retail) is £169, and the Square Terminal (all-in-one device with printer) is £219. While the initial hardware cost can be higher than SumUp or Zettle, Square provides a fully integrated system with POS software, inventory, staff management, and invoicing.
Square charges a 1.75% per transaction fee in the UK, matching Zettle, but its standout feature is the payout speed. Square typically deposits funds to your UK bank the next business day, which can be a crucial advantage for cashflow-sensitive businesses like hairdressers or market traders.
Square also supports contactless, chip & PIN, and mobile wallet payments, plus integrates with popular accounting tools such as Xero. Its intuitive dashboard and detailed reporting tools help you track sales trends and manage your business efficiently.
- Hardware cost: £20 (Reader), £169 (Stand), £219 (Terminal)
- Transaction fee: 1.75% per transaction
- Payout speed: Next business day
- Monthly fees: None, no contract
- Powerful POS software, inventory, and invoicing
If you need quicker access to your funds, Square’s next-day payout system can improve cash flow management, especially for businesses with tight margins.
Comparing Fees and Hardware Costs for UK Small Businesses
To summarise the cost differences, here’s a practical comparison for a UK hairdresser or market trader processing around £2,000 in card payments per month.
- SumUp: £29 hardware + £33.80 fees (1.69%) = £62.80 first month
- Zettle: £29-£79 hardware + £35 fees (1.75%) = £64-£114 first month
- Square: £20-£219 hardware + £35 fees (1.75%) = £55-£254 first month
SumUp offers the lowest upfront hardware cost and slightly lower fees, making it ideal for low-volume sellers or those just starting out. Zettle provides a balance between hardware options and features, especially if you already use PayPal. Square’s higher hardware cost might be justified by its advanced software and faster payouts, particularly for established businesses needing detailed sales management.
Payout Speed and Cash Flow Considerations
Cash flow is the lifeblood of any small business or side hustle. Waiting several days for payments to clear can cause headaches, especially if you rely on that income to restock or pay suppliers. Here’s how the providers compare for UK users:
- Square: Funds typically paid into your bank account the next business day, improving cash flow.
- SumUp: Standard payout times are 1-2 business days; delays can occur over weekends or holidays.
- Zettle: Similar timing to SumUp, with 1-2 business days, but instant transfers possible if using PayPal wallet.
For market stall holders working weekends or event traders at weekend festivals, this payout timing is important. Square’s quicker payout can help smooth cash flow, but SumUp and Zettle are adequate for many businesses that manage their finances weekly or monthly.
Real UK Business Examples
Jenny runs a hairdressing salon in Bristol and processes about £3,000 monthly in card payments. She chose Square because the software integrates with her appointment booking system and she values the next-day payout. The upfront £169 on the Square Stand paid off in time saved on admin and faster access to funds.
Tom, a market trader in Manchester selling handmade jewellery, opted for SumUp because of the low hardware cost and flat 1.69% fee. His average transaction is £15, and he appreciates how lightweight and simple the reader is for daily set-up.
Sophie, who runs a food stall at various UK festivals, uses Zettle. She likes the option to print receipts on the Pro reader and the PayPal integration for online sales during off-season. The slightly higher fee is offset by convenience and multi-channel sales management.
"“Choosing the right card payment system was a game changer for my salon. Square’s integrated software saved me hours of admin every week, and the faster payouts helped me keep the business running smoothly.” – Jenny, Bristol hairdresser"
How to Get Started with Your Chosen Provider
Once you’ve decided which provider fits your business needs, the next steps are straightforward:
- Visit the provider’s UK website (SumUp, Zettle, Square) and order your card reader hardware.
- Download the provider’s app on your smartphone or tablet (check compatibility with your device).
- Complete the registration and identity verification process, including providing your UK bank details for payouts.
- Set up your product catalogue or services within the app if you wish to track sales and inventory.
- Test the card reader with a small transaction to ensure everything works smoothly.
- Start accepting card payments in person at your market stall, salon, or event.
HMRC requires accurate business details for tax and compliance purposes. Make sure the business name and bank account you register with your card payment provider match your official records to avoid payout delays.
Final Thoughts: Which Card Payment Solution is Best for You?
SumUp is best suited for new or low-volume sellers who want low hardware costs and simple fees. Zettle appeals to those wanting PayPal integration and more versatile hardware options, such as receipt printers. Square is ideal for businesses needing robust POS software, detailed reporting, and faster access to funds, despite a higher upfront hardware investment.
Ultimately, the best choice depends on your transaction volume, business type, and which features help you run your business more efficiently. Consider hardware portability, fees, payout speed, and software tools before committing.
Whichever provider you choose, accepting card payments in person will help you meet customers’ expectations, increase your sales, and keep your business competitive in the UK’s evolving retail and service landscape.
