POS Systems for Your Business 2026

Whether you’re running a market stall, a boutique, or a busy café, a good POS (point of sale, not the other thing) system does more than just take payments. It should speed up your queue, keep your stock in check, and ideally, make your bookkeeping easier rather than harder. (And if it doesn’t it’s time for a new one.)

To help you out, we’ve compared the most popular POS systems available to UK small businesses in 2026, looking at pricing, transaction fees, features, and who each one actually suits. Because it isn’t all one-size-fits-all.

Here’s everything you need to pick the right one.

What is a POS system?

A POS (point of sale) system is the combination of hardware and software you use to take payments and process sales. This could include a card reader on its own, or a full till setup with stock and staff management software built in.

Most modern POS systems also track your sales data, manage inventory, and can connect to your accounting software so those transactions show up in your records automatically. Sounds exhausting.

Square: best all-round POS system

Square’s free plan makes it a solid starting point for most small businesses, with a 1.75% in-person transaction fee and no contract to worry about. It’s widely rated as one of the easiest systems to learn, which matters if you’ve got staff to train up during a busy shift.

SumUp: best for keeping costs low

SumUp keeps things simple, with a free plan, competitive in-person fees, and affordable card readers starting from around £25.

If you upgrade to the Payments Plus plan (£19/month), your transaction fee can drop as low as 0.99%, which could be worth doing if you’re processing more than a couple of thousand pounds a month in card sales.

PayPal Point of Sale (formerly Zettle): best for PayPal users

If you already invoice or sell online through PayPal, PayPal Point of Sale (still widely known as Zettle) pulls your in-person and online payments into one dashboard. It’s a straightforward, contract-free option with a 1.75% transaction fee and a genuinely quick setup.

Shopify POS: best for combining in-store and online sales

Shopify POS is built for businesses that sell both online and in person, syncing stock and sales across both so you’re not double-selling the same item in-store and on your website. It’s a pricier option, since you’re essentially paying for a full ecommerce platform with POS built in, starting from £25/month – or £19/month if billed annually.

Clover: best for growing retail businesses

Clover offers well-designed hardware and detailed sales reporting, including hour-by-hour revenue breakdowns that can help with staff scheduling. Pricing is largely quote-based, and contracts are common, so it suits businesses that are confident about committing for the longer term.

Lightspeed Retail: best for multi-location businesses

Lightspeed is built for retailers managing complex or high-SKU stock across more than one site, with strong inventory tools and add-on modules for loyalty and analytics. It’s the most expensive option here, starting from £75/month for a single location and register.

How to choose the right POS system for your business

Here are some top tips to choosing the right POS system that won’t wrestle with your business.

Work out your actual card turnover

Flat-rate providers like Square and PayPal Point of Sale are usually cheapest at lower volumes. Once you’re regularly processing a few thousand pounds a month in card sales, a plan with a monthly fee and lower percentage rate (like SumUp’s Payments Plus) can work out cheaper overall.

Good financial reporting will help you identify each income stream! We’re not being subtle with the big blue banner below.

Check the contract length

Square, SumUp, and PayPal POS are contract-free. Others, such as Clover, often ask for a minimum term, so factor that in if you’re not sure the system’s right for you long-term.

Match the features to your business

A market stall needs very little beyond a card reader. A shop with hundreds of product lines needs proper stock management. Don’t pay for complexity you won’t use. It’s like bulk buying car air fresheners when you don’t drive.

Think about scalability

If you’re planning to open a second site, look for built-in multi-location support rather than a workaround.

Check how it connects to your bookkeeping

This is the bit that gets overlooked, and it’s the one that saves you the most admin time. A bit like bank feeds, connecting your transaction records to your bookkeeping will dramatically reduce the amount of time you spend on data-entry or wrestling with data uploads.

Getting your POS transactions into your bookkeeping

However good your till is, those sales still need to end up in your accounts. Most POS providers pay your daily takings into your bank account as a lump sum, which means the individual sale isn’t automatically recorded in your bank account, just the total. It means that a bank feed might show the total amount you make each day, but not the individual transactions.

Using different types of payment feeds

The easiest way to deal with this in your bookkeeping software is to treat your card payouts the same way you’d treat any other bank feed; connect your account so the payout feeds into your records automatically, then categorise it.

If your provider doesn’t offer a direct integration, entering the summary total as a manual transaction works just as well; our guide to recording ecommerce and marketplace sales walks through exactly this process, and the same approach applies to POS payouts from providers like Square or SumUp.

Taking invoiced payments alongside till sales

If you’re taking invoiced payments alongside your till sales, say, for larger orders or trade customers – Pandle Pay lets customers pay by card directly from an invoice. The payment is matched to the right invoice automatically once it comes in, rather than you having to do it manually.

You can read more about how that payment allocation works or browse our full collection of guides on customer invoices and payments.

Whichever route you take, the goal is the same: your bank balance in your bookkeeping should always match what’s actually sitting in your account. If it doesn’t, our guide to bank reconciliation is a good place to start untangling where things went wrong.

Getting your till and your books talking to each other is a lot less painful with the right tool for the job. Pandle handles bank feeds, invoicing, and cash flow tracking in one place.
