EPOS system vs cash register: which does a small food business need? (2026 guide)
A cash register adds up and opens a drawer. An EPOS system runs the order from the counter to the kitchen, the card machine and the accounts. Here is where the gap costs you money, where it does not, and what moving across actually involves.
- What a cash register genuinely cannot do
- The honest break-even for a single site
- Complete EPOS systems from £499 + VAT

Short answer
A cash register is the right tool for a business that sells a short list of fixed-price items, takes cash or a standalone card reader, and does not need to know afterwards what it sold. For anything that cooks to order, an EPOS pays for itself quickly: the order prints in the kitchen instead of being shouted, extras are priced instead of scribbled, the card machine takes the exact total, and the end-of-day report shows what actually sold. UK till hardware typically costs £300–£1,500 one-off with software at £25–£70 a month, against £100–£300 for a register. If an EPOS saves a counter doing 120 orders a day one wrong order per shift, it is ahead within a quarter. Posso systems start at £499 + VAT with the kitchen printer included.
Key takeaways
- A cash register records a sale; an EPOS system runs the order through the kitchen, card machine and reports.
- The register wins on price and simplicity, and it never needs an update or an internet connection.
- For a site cooking to order, kitchen printing and priced modifiers alone usually justify the switch.
- Switching takes a menu build, a float count and a first Z report, not a rebuild of the business.
Takeaway: If your orders have options, go to a kitchen or arrive by phone or app, a cash register is already costing you more than an EPOS would.
Why the question matters more than it used to
Ten years ago the gap between a register and an EPOS was mostly reporting. The register gave you a total; the EPOS gave you a breakdown. Plenty of owners decided, reasonably, that they knew what they sold.
The gap is different now. Orders arrive from a counter, a phone, a website and three delivery apps. Card is the majority of payments. Menus have options on most items. A register was never designed for any of that, so the work moves to the people: someone re-keys the Just Eat order onto a ticket, someone shouts the kebab with no salad, someone types £14.80 into a card reader and someone balances a drawer against five sources at midnight.
The mistake people make in both directions is the same: comparing the two on purchase price. A register at £150 and an EPOS at £499 looks like a £349 question. It is actually a question about how many minutes a day staff spend doing what the till should do, and how many orders a week go wrong because the till could not carry the detail. For the wider comparison of till types, start at compare EPOS systems.
What a cash register cannot do, and what it still does well
Each principle below is the thing that actually changes when you move from a register to an EPOS. Judge your own counter against them honestly.
Print the order where it is cooked, not where it is paid
A register takes money at the counter; the kitchen learns about the order by voice or a handwritten ticket. At 6:45pm on a Friday with twelve orders in the queue, that is where a chicken shawarma becomes a lamb one. An EPOS sends the order to a kitchen printer or kitchen display screen the moment it is placed, with the time, the order number and every option, so the kitchen cooks from the record the customer paid against. One remade £9 order a shift is £63 a week in food, plus the customer who does not come back.
Price the extra, do not note it
Registers hold fixed prices on fixed keys. Extra cheese, large chips, no onions, double meat: either you add a key for every combination or staff type a price by hand and write the detail on the ticket. In practice they stop charging for the small ones. Extra sauce at 50p across 80 orders a day is £40 a day, over £14,000 a year, that a register lets slip. An EPOS prices the modifier on the item, prints it on the kitchen ticket and counts it in the report, which is the only way to learn what your extras are worth.
Let the card machine take the total, not a typed number
With a register and a standalone reader, someone reads £23.40 off the till and types it into the terminal. Type £32.40 once a week and the drawer never balances; type £2.34 and you have lost £21. An integrated EPOS pushes the exact total to the card machine, records the tender type and ties the card settlement to the Z report. If you are weighing up which machine, card machine fees explained covers what the percentages mean on a £12 ticket.
Report what sold, not just what was taken
A register tells you Tuesday took £1,140. An EPOS tells you Tuesday sold 61 portions of chips, that cod outsold haddock three to one, that 70% of sales landed between 5pm and 8pm, and that the new wrap sold four. That is the difference between buying stock on habit and buying it on numbers. It also shows voids, no-sales and discounts by staff member, the fastest way to find out why the drawer is £30 short on the same shift every week.
Take the online and phone orders into the same queue
A register has no way to receive an order. Website, app, Just Eat, Uber Eats and Deliveroo orders arrive on tablets or by phone and someone re-keys them. At 40 delivery orders a night, that is roughly forty minutes of typing and a steady trickle of mistakes. An EPOS with delivery integrations brings every channel into one order screen and one kitchen printer, so the Friday rush is managed in one place instead of across a tablet wall.
Respect what the register does well
A register is cheap, usually £100–£300. It boots in seconds, never asks for an update, works with the internet down because it never had internet, and needs no training beyond which key is which. For a market stall selling six drinks at fixed prices or a club bar taking cash, that is exactly right and an EPOS is solving problems it does not have. If none of the five points above apply to your counter, keep the register and spend the money on a better coffee machine.
Cash register vs EPOS system: side by side
Typical UK figures for a single-site food business. The register column assumes a standalone card reader alongside it.
| Cash register | EPOS system (UK typical) | Posso | |
|---|---|---|---|
| Upfront cost | £100–£300 | £300–£1,500 hardware | £499 + VAT, printers and drawer included |
| Ongoing cost | None | £25–£70 a month software | From £25 + VAT a month |
| Speed at the counter | Fast on fixed items, slow on options | Fast with a well-built menu | Touchscreen with modifiers one tap deep |
| Reporting | Daily total, department totals | Item, hour, staff, tender, void reports | Full sales, product and staff reporting, Xero sync |
| Kitchen | Shouted or handwritten | Kitchen printer or display screen | Kitchen printer included; display from £399 + VAT |
| Card payments | Standalone reader, total typed in | Integrated terminal takes the exact total | Posso Pay from 1% + 10p, quoted on card turnover; Teya and Dojo supported |
| Online orders | Not possible | Via integration, often £0–£60 a month per platform | Just Eat, Uber Eats, Deliveroo for £45 a month, unlimited orders |
| Offline | Always works | Varies: some cloud tills stop | Offline-first local database, keeps trading |
| Multi-site | Separate machines, separate totals | Usually a higher software tier | One back office across sites |

What to ask a provider before you sign
What happens if the internet goes down?
Your register never cared. Some cloud tills do: no connection, no orders, no card. Ask whether the till keeps a local copy of the menu and the day's sales and syncs when the line returns, and whether the card machine can still authorise. A supplier who answers "it rarely happens" has answered. Pull the router out during the demo and see. What happens when an EPOS goes offline sets out what good looks like.
Who builds the menu, and what does it cost to change it?
Coming from a register, the menu build is the switch: every item, every size, every modifier with its price, VAT treatment for eat in and takeaway, the kitchen printer each category routes to. Ask who does it, whether it is included, and whether you can change a price yourself on a Tuesday night without a support ticket or a fee. A build you cannot edit is a build you will stop trusting within three months.
What does the end of day actually involve?
On a register you count the drawer against the X total and hit Z. On an EPOS you should get the same and more: cash by drawer, card by terminal, delivery platforms by channel, on one sheet, so a £17.40 difference is traceable to a tender rather than a mystery. Ask to see a real Z report from a live site. If it cannot show card totals alongside the till, you will be reconciling two systems by hand every night, which is what you were leaving behind.
The Posso approach to replacing a cash register
Posso is a hospitality-only EPOS built and supported from Leicester, running on 500+ UK sites. The £499 + VAT system is a complete replacement for a register and the reader beside it: touchscreen terminal running Windows 11 Pro, kitchen printer, receipt printer and cash drawer, with the menu build and staff training included. Software is from £25 + VAT a month and you own the hardware outright.
The pieces a register cannot do are the standard build. Modifiers carry their own price and print on the kitchen ticket. Card payments run through Posso Pay, Posso's own merchant service, from 1% + 10p quoted on your card turnover, with the exact total pushed to the terminal and the settlement on the Z report; Teya and Dojo terminals are also supported. Just Eat, Uber Eats and Deliveroo orders arrive in the same order screen and kitchen queue for £45 a month with unlimited orders.
The database is local and offline-first, so a dropped line does not stop the counter, which matters to anyone whose register never once failed. Support is UK-based, Monday to Friday, 9am–9:30pm, with an urgent out-of-hours line for till-down problems, and the hardware carries a two-year warranty. If cash flow is why the register has lasted this long, finance is available from £24.92 a week.
Setup (menu build + configuration) is free; on-site installation for larger sites is priced on application. Systems are preconfigured and shipped plug-and-play.
Where to look elsewhere
If your counter sells a fixed, short list at fixed prices, takes mostly cash and has no kitchen, a cash register or a card reader with a simple app is the correct answer and we would say so on the phone. The same goes for a club bar that opens two nights a week: the monthly software on any EPOS is money for a problem you do not have.
And if the business is really a shop, with barcodes, suppliers and hundreds of stock lines, you need a retail platform with proper purchasing and stock control. Posso is built for food and drink; a retail-first system will serve a shop better.

EPOS vs cash register: frequently asked questions
What is the difference between a cash register and an EPOS system?
A cash register totals a sale, prints a receipt and opens the drawer; it holds fixed prices on fixed keys and its reporting stops at a daily total. An EPOS system runs the whole order: it prices options on each item, prints to the kitchen, pushes the exact total to the card machine, receives online and delivery orders, and reports what sold by item, hour and staff member. The register is cheaper and simpler; the EPOS removes the manual work that grows around a register in any kitchen cooking to order.
How much does it cost to switch from a cash register to an EPOS?
UK till hardware typically runs £300–£1,500 one-off with cloud software at £25–£70 a month, and some suppliers charge £0–£300 for installation. A complete Posso system is £499 + VAT including the touchscreen terminal, kitchen printer, receipt printer, cash drawer, menu build and training, with software from £25 + VAT a month. The real comparison is what the register costs you in re-keying, uncharged extras and wrong orders each week.
Is a cash register still good enough for a small takeaway?
Only if the menu has few options, the kitchen can hear the counter, and you take no phone, web or delivery-app orders. The moment orders carry modifiers, go to a kitchen out of earshot or arrive from a tablet, the register hands that work to staff. For a takeaway doing 100 orders a night across counter, phone and two platforms, re-keying alone is typically over half an hour a shift, before the wrong orders are counted.
What is the break-even on an EPOS for a small site?
Work it on three lines. Uncharged extras: 50p on 60 orders a day is £30 a day. Re-keying: 30 delivery orders a night at a minute each is half an hour of staff time. Remakes: one £9 wrong order a shift. Any one of those covers £25 + VAT a month of software several times over, and together they usually repay a £499 + VAT system inside a quarter. If none apply, the break-even is never and the register is right.
What does switching from a cash register to an EPOS actually involve?
Three things. A menu build: every item, size and modifier with its price and VAT treatment, and which printer each category goes to. A clean handover day: count the float, Z the register for the last time, start the EPOS with the same float so the first report reconciles. Then two weeks of reading the Z report every night and fixing what it reveals: a modifier at the wrong price, a category on the wrong printer. Your customer list can be loaded in; historic sales from the register cannot.
Do I lose the ability to trade if the internet goes down?
On a register, no. On an EPOS, it depends on the design. Pure cloud tills can stop taking orders and payments when the line drops; offline-first systems keep a local copy of the menu and the day's sales on the terminal and sync when the connection returns. Ask any supplier to show you the till trading with the router unplugged. Posso uses a local database for this reason.
