EPOS Systems Explained: What Every Business Owner Needs to Know

If you're still using a basic cash register — or worse, scribbling orders on a notepad — a modern EPOS system could transform how your business operates. But with so many options and price points, it's hard to know what you actually need. This guide cuts through the noise.

What is EPOS?

EPOS stands for Electronic Point of Sale. It's a smart till system that does far more than just process payments. A modern EPOS system combines:

• Sales processing — ring up sales, apply discounts, split bills
• Card payments — take contactless, chip & PIN, Apple Pay, Google Pay
• Stock management — track inventory in real time, set low-stock alerts
• Staff management — clock in/out, track individual sales, set permissions
• Reporting — see your best sellers, busiest hours, daily/weekly/monthly revenue
• Customer management — store customer details, purchase history, loyalty points

Do I need one?

If your business sells products or services in person and you answer yes to any of these, an EPOS system will pay for itself:

• You spend time manually counting stock or doing end-of-day reconciliation
• You don't know which products sell best or which hours are busiest
• You can't easily track what your staff are selling
• You're using a separate card machine that doesn't talk to your till
• You're losing track of what's in stock and over-ordering (or running out)

How much does it cost?

EPOS costs break down into hardware (the physical till) and software (the system that runs on it):

Option 1: Buy outright

Pay for the hardware upfront and own it. Typical costs: £199–£799 for the hardware plus £25–£50/month for the software. You own the equipment and can switch software providers if you want. This usually works out cheaper over 2+ years.

Option 2: Rent monthly

Pay nothing upfront and rent the hardware as part of your monthly fee. Typical costs: £30–£60/month all-in. The catch: you're locked into a longer contract (often 36 months) and the hardware goes back at the end. Over 3 years, you'll pay more total, but there's no upfront cost.

Option 3: Free software + BYO hardware

Some providers like Loyverse offer free EPOS software that runs on your own tablet. You buy an iPad or Android tablet (£200–£500) and any peripherals you need (receipt printer, cash drawer, barcode scanner). No monthly software fee, but features are basic and card machine integration is limited.

Retail vs hospitality: different needs

Not all EPOS systems are equal. The features that matter depend on your industry:

Card machine compatibility — this matters more than you think

Some EPOS systems only work with their own branded card machine. This means you can't shop around for the best card processing rates — you're locked into whatever rate the EPOS provider charges.

Systems like Epos Now integrate with most major card machine providers, which means you can negotiate your transaction rate independently. Over a year, the difference between a competitive rate (0.5%) and an inflated one (1.7%) on £50,000 of card turnover is £600. That adds up fast.

Questions to ask before you buy

• Do I own the hardware at the end of the contract, or does it go back?
• Can I use any card machine provider, or am I locked into yours?
• What happens if I want to leave early — are there exit fees?
• Is the software cloud-based (can I access reports from anywhere)?
• Does it integrate with my accounting software (Xero, QuickBooks)?
• What support is included — and what hours is it available?
