Best POS System for Small Business UK: Comparison Guide 2026

There’s no single best POS system for small business, because the right choice depends on the kind of business you’re running, a market stall, a busy café, a multi-till retail shop, or a group of pubs. What we can do is compare the main UK-available systems side by side on the things that actually affect your monthly bill: software cost, transaction fees, contract length, hardware outlay, and how well each one copes when the internet drops.

This guide compares six of the most widely used point of sale systems for small business in the UK, based on published pricing and independent reviews checked in mid-2026. You’ll find a comparison table, honest breakdowns of each provider, and three or four use-case recommendations rather than one forced winner.

How We Compared These Systems (Methodology and Disclosure)

Before the table, a word on how this comparison was built and what it isn’t.

What we checked: monthly software cost, per-transaction card fees for in-person payments, typical contract length, starting hardware outlay, and whether each system keeps working during an internet outage. Figures come from each provider’s own UK pricing pages plus independent UK review sites, checked in June and July 2026. Pricing changes often in this market, sometimes within weeks, so treat every figure here as a starting point and confirm the current rate directly with the provider before signing anything.

What we didn’t do: we didn’t accept payment from any provider to appear here or to be ranked more favourably, and this page doesn’t declare a single “winner.” Some outbound links on Driftfolio may be affiliate links, meaning we could earn a small commission if you sign up through them, at no extra cost to you. That relationship never changes what appears in the comparison table or how a provider is described.

A note on transaction fees: several providers, including Lightspeed and TISSL, don’t publish a flat UK transaction rate and instead quote based on your business type and volume. Where that’s the case, we’ve said so rather than guessing a number.

Best POS Systems for Small Business UK: Comparison Table

Best Rated POS Systems: Individual Breakdowns

Square

Square runs on a genuinely free plan: no monthly software fee, no contract, and you only pay when you take a payment. In-person UK card transactions cost 1.75%, and online payments with UK cards cost 1.4% plus 25p. Hardware starts at £19 for a basic reader, with paid plans (Plus and Premium) offering lower transaction rates and extra features like advanced retail reporting and team management for businesses that outgrow the free tier.

Square suits small, in-person businesses that want to start trading quickly without signing anything, and it scales reasonably well if you later need restaurant or retail-specific tools. It’s less convincing for businesses that process high volumes and could get a better rate elsewhere, or for anyone who needs strong offline resilience during frequent connectivity drops.

SumUp

SumUp keeps things simple with pay-as-you-go pricing: 1.69% per in-person transaction, no monthly fee, and hardware bought outright rather than rented. The Solo reader (£79 + VAT) includes a 4G SIM, so it can keep working without Wi-Fi or a paired phone, a genuine advantage for market traders and mobile services. Businesses processing higher volumes can switch to Payments Plus at £19 a month, which drops the rate to 0.99%, or step up to POS Pro from £49 a month for fuller till software with stock and staff tools.

SumUp works well for anyone who wants predictable, contract-free costs and doesn’t need deep retail-specific features out of the box. It’s a weaker fit for busy restaurants that need table management or kitchen printing, since those features sit outside SumUp’s usual strengths.

PayPal POS (formerly Zettle)

PayPal POS charges a flat 1.75% per in-person transaction with no monthly fee and no contract, making it directly comparable to Square on price. A first card reader costs £29 plus VAT, with a dedicated terminal available at £149 plus VAT for businesses that want a more complete counter setup. The built-in inventory and sales tools cover the basics well, though several UK reviews note the feature set is lighter than Square’s once you go beyond simple sales tracking.

This one suits sole traders, salons and small independent shops already comfortable in the PayPal ecosystem, particularly if you value simplicity over a long feature list. Businesses wanting deeper retail reporting or restaurant-specific workflows will likely outgrow it.

Epos Now

Epos Now sells a more traditional full counter setup: a touchscreen terminal, cash drawer and receipt printer bundled from around £199 to £249, alongside software subscriptions typically running £25 to £39 a month. In-person card payments through Epos Now Payments run at roughly 1.5%, which beats Square and PayPal POS’s flat 1.75% once you’re processing meaningful volume.

The catch, and it’s a real one, is contract length. Multiple independent UK reviews report standard terms of 24 to 36 months, with some buyers describing longer commitments and costly early exit terms. If you go this route, get the exact contract length, renewal terms and cancellation fees confirmed in writing before you sign anything, since Epos Now’s own pricing page redirects to a quote form rather than listing every fee up front. It’s a solid option for established retail or hospitality businesses that want a proper counter setup with UK-based support, less so for a new business still testing whether the model works.

Lightspeed Retail

Lightspeed positions itself for retail and hospitality businesses that have outgrown a basic card reader and need real inventory depth. UK Retail plans start at £75 a month for a single register (Basic), rising to £149 (Core) and £189 (Plus) as you add features like advanced reporting and multi-location stock control. Restaurant plans start separately at £79 a month. Transaction fees aren’t published for UK merchants and are quoted individually based on volume and business type.

Billing is monthly with the option to cancel at month end, or annual with a discount if you’re confident in the commitment. Offline mode is included, letting you keep selling and queue card payments during a connectivity drop, with everything syncing once you’re back online. Lightspeed makes sense for growing retailers managing multiple locations or complex stock ranges. It’s overkill, and needlessly expensive, for a single-till shop that just needs to take payments and track basic stock.

TISSL

TISSL is a UK hospitality specialist built around a licence-based pricing model rather than charging per device. Plans start from £60 a month for a bundle of five user licences, rising to higher tiers for more advanced features, and you can add as many terminals as you like within a licence bundle without extra device fees. That structure suits busy multi-terminal venues, pubs and restaurant groups managing several sites from one back office.

Transaction fees through TISSLPay aren’t published and require a direct quote. Independent reviews flag a lower Trustpilot score than some rivals and note that contract terms should be requested and confirmed in writing before committing. TISSL fits multi-site hospitality operators who want centralised control across venues. A single small café or shop is unlikely to need, or want to pay for, this level of complexity.

Best EPOS Systems by Business Type

Rather than naming one winner, here’s how the same six systems stack up once you factor in what you actually sell and how you sell it.

Market Traders and Mobile Businesses

SumUp and PayPal POS both suit pay-as-you-go trading well, since neither charges a monthly fee and both work from a phone or lightweight reader. SumUp’s Solo reader has the edge here thanks to its built-in 4G, useful anywhere Wi-Fi isn’t reliable, such as outdoor markets or festivals.

Cafés and Small Independent Retail

Square is a strong starting point for a single till taking mostly card payments, given the free software and 1.75% flat rate. If stock tracking matters more than a low headline fee, SumUp’s POS Pro or Epos Now’s bundled hardware are both worth comparing once you’ve priced up the monthly cost against your expected sales volume.

Growing Retail with Multiple Locations or Complex Stock

Lightspeed Retail is built for this scenario specifically, with multi-location inventory, purchase orders and supplier catalogues that the free-tier systems simply don’t offer. The higher monthly cost is easier to justify once you’re managing stock across more than one site.

Multi-Site Hospitality: Pubs, Bars and Restaurant Groups

TISSL’s per-user licensing and centralised multi-venue reporting suit pub and restaurant groups managing several sites under one back office. For a single independent restaurant or pub, Square for Restaurants or Epos Now are usually more proportionate, since they cover table management and kitchen workflows without TISSL’s multi-site pricing structure.

POS Systems UK: Contract Length and Offline Capability Explained

Two details separate a good fit from a bad one more reliably than the headline monthly price: how long you’re locked in, and what happens when your internet drops mid-service.

Contract length varies enormously across this market. Square, SumUp and PayPal POS all operate on a genuine pay-as-you-go basis, so you can stop using them at any point without a cancellation fee. Epos Now, by contrast, commonly runs 24 to 36 month contracts, and some buyers report longer terms with early exit fees running into the thousands. Lightspeed sits in between, offering month-to-month billing you can cancel at any point, or an annual plan with a discount if you’re comfortable committing. Always ask for the exact minimum term, renewal terms and cancellation fees in writing before signing, since sales pages and verbal assurances aren’t the same as the actual contract clause.

Offline capability matters more than most first-time buyers expect, particularly for businesses in areas with patchy broadband or mobile signal. SumUp’s 4G-enabled readers and Lightspeed’s built-in offline mode both let you keep taking payments during an outage, queuing transactions to process once connectivity returns. Epos Now offers reduced offline functionality, meaning core sales can continue but cloud reporting and some integrated app features pause until you’re back online. Square and PayPal POS offer more limited offline support by comparison, so if a stable connection genuinely can’t be guaranteed at your premises, this is worth testing before you commit rather than after.

According to the Payment Systems Regulator’s 2022 remedies, card payment terminal lease and rental contracts from directed acquirers must now carry an initial minimum term of no more than 18 months, rolling on to no more than 31 days afterwards, with cost-based and clearly explained exit fees. That rule applies to card machine rentals specifically rather than every POS software contract, so it’s worth checking whether your quote is covered by it or sits outside that protection.

Best Point of Sale System: How to Choose

With six credible options on the table, the decision usually comes down to four questions worth answering honestly before you request a quote.

• How many transactions do you process a month, and at what average value? High volume makes a lower percentage fee (like Epos Now’s roughly 1.5%) worth more than it looks on paper, while low, sporadic volume usually favours a free, no-monthly-fee plan like Square or PayPal POS.
• Do you need real stock control, or just payment processing? If you’re tracking hundreds of SKUs across more than one site, Lightspeed or Epos Now will save you time that a basic card reader system can’t.
• How reliable is your internet connection? If outages happen more than occasionally, prioritise a system with genuine offline resilience over one with a slightly lower headline fee.
• Can you commit to a contract, or do you need to walk away at short notice? New and untested businesses generally do better on pay-as-you-go systems until sales patterns are established, saving longer commitments for once the numbers are proven.

FAQs

What is the best POS system for a small business in the UK? 

There isn’t one single best system, since the right choice depends on your sales volume, sector and whether you need stock control across multiple sites. Square and SumUp suit low-cost, contract-free starts, while Lightspeed and TISSL suit growing retail and multi-site hospitality respectively.

What is the cheapest POS system for a small business? 

Square, SumUp and PayPal POS all offer free software with no monthly fee, charging only a per-transaction fee (1.69% to 1.75% for in-person UK card payments). For a very small or seasonal business, this pay-as-you-go structure is usually the lowest-cost option overall.

Do I need a contract for a POS system? 

No, not necessarily. Square, SumUp and PayPal POS all operate without a fixed contract, while providers like Epos Now typically require 24 to 36 month agreements. Always confirm the exact contract term and any exit fees in writing before signing.

What’s the difference between POS and EPOS? 

In the UK, “POS” and “EPOS” (Electronic Point of Sale) are largely used interchangeably today to describe modern, software-driven till systems. Some guides still use “POS” for basic, offline tills and “EPOS” for connected systems with stock and reporting built in.

Can a POS system work if the internet goes down? 

Most modern systems include some offline mode, letting you continue processing sales and queuing card payments until the connection returns. The depth of that offline support varies significantly between providers, so it’s worth testing before committing if reliable connectivity is a concern.

How much does a POS system cost for a small UK business? 

Costs range from free (with a per-transaction fee of around 1.5% to 1.75%) up to roughly £75 to £190 a month for fuller-featured retail or hospitality systems, plus separate hardware and card processing costs either way. Prices change often, so always check a provider’s current UK pricing page before deciding.

Which POS system is best for a market trader or mobile business? 

SumUp and PayPal POS both suit mobile trading well, since neither charges a monthly fee and both work from lightweight, portable hardware. SumUp’s 4G-enabled Solo reader has an edge for locations without reliable Wi-Fi.

Which POS system is best for a multi-site restaurant or pub group? 

TISSL’s user-based licensing and centralised multi-venue reporting are built specifically for managing several hospitality sites from one back office. For a single independent venue, Epos Now or Square for Restaurants are usually a more proportionate fit.
