Free EPOS for UK Pubs: Square vs SumUp vs Goodtill

Last updated: 23 April 2026

Most EPOS comparisons tell you what software costs, not what it costs you when the system fails at 9pm on a Saturday with a queue at the bar. The real question isn’t whether Square, SumUp, or Goodtill are free — it’s whether they work when you need them most.

I’ve run 180 covers through Teal Farm Pub for 15 years and spent the last three months testing these three systems during genuine peak trading: card-only payments, kitchen tickets flying, bar tabs stacking, and multiple staff hitting the same terminal. Most systems that look good in a demo struggle when there’s actual pressure on the till.

The most important discovery: “free” EPOS systems often have hidden costs that exceed the monthly fees of premium alternatives. This guide is built on real-world testing, not marketing claims.

You’ll learn exactly what each system delivers, where they fail, and whether your pub actually needs the one everyone talks about.

Why Free EPOS Systems Look Good But Cost Money

When I first heard about free EPOS systems, my instinct was the same as yours: if it costs nothing, where’s the catch? The catch isn’t hidden — it’s just not obvious until you actually try to run a pub on one.

The real cost of an EPOS system is not the monthly fee but the staff training time and the lost sales during the first two weeks of use. A free system that takes three hours to train your team on costs you more than a system with a £50 monthly fee that your staff learns in 45 minutes.

I tested this. On the first Saturday night we switched systems at Teal Farm, our transaction time per card payment went up by an average of 18 seconds. On a busy night with 200+ transactions, that’s 60 minutes of lost service speed. You can’t see that cost on an invoice, but you feel it in the queue at the bar.

Here’s what actually happens with free EPOS systems for pubs:

• You pay in payment processor rates. Free systems make money by charging you higher card processing fees — typically 1.75% vs 1.49% on premium systems.
• You pay in features you can’t remove. The system bundles features you don’t need, taking screen space away from what you do.
• You pay in support time. When something breaks on a Wednesday night, you’re waiting for an online help ticket, not a phone call to a dedicated account team.
• You pay in migration costs if you outgrow it. Switching from free to paid mid-way through growth means re-training, new integrations, and lost history.

That’s not to say free systems are bad. For a very specific type of pub, they’re exactly right. But they’re right for fewer pubs than the marketing suggests.

Square POS: The Popular Choice (And Its Real Limits)

Square is the system everyone knows. It’s popular because it’s genuinely easy to set up — literally five minutes from deciding to buy to taking your first payment. For a coffee shop, a small retail business, or a one-person operation, it’s probably the right choice.

For a pub doing 180 covers on a Saturday with three staff, card-only takings, kitchen integration, and bar tabs, it’s a different story.

Square works until you need two things at once: simultaneous payments on different terminals and accurate split bills. I tested this explicitly. On a Friday night at Teal Farm with two staff on tills and a queue backing up to the door, I processed a payment on one terminal while another staff member tried to ring in a split bill on the second Square terminal. The payment delayed by 8 seconds while the till caught up with itself. In normal circumstances that’s barely noticeable. When you’ve got 15 people waiting and it happens on every other transaction, your customers feel it.

Here’s what Square actually gives you:

• Genuinely free base system — no monthly subscription
• 1.75% card processing rate (standard for free systems)
• Works on iPad or Android tablet
• Basic split bills and bar tabs
• Integrates with some kitchen display systems (KDS)

What it doesn’t give you (unless you pay extra):

• Reliable multi-terminal concurrency during peak trading
• Employee reporting that shows labour as a percentage of takings
• Integration with cellar management systems (crucial for tied tenants)
• Customisable loyalty programs or printed receipts at card terminal
• Advanced void/refund controls (important for audit compliance)

Most licensing premises have 5-star EHO requirements around void and refund tracking. Square’s basic system logs them, but doesn’t give your manager oversight without digging into transaction lists. That’s a compliance issue, not a feature.

SumUp and Goodtill: The Underdog Play

SumUp and Goodtill are the same company — SumUp owns Goodtill and offers it as the purpose-built EPOS platform, while SumUp is the payment processor behind it. This matters because it removes one of the biggest hidden costs: you’re not paying two separate companies to make their systems talk to each other.

I tested Goodtill for two months at Teal Farm. Here’s what I found.

Goodtill costs £49 per month, but this includes features that Square charges extra for — and it includes a better payment processor rate (1.49% instead of 1.75%). On £20,000 monthly takings (typical for a 180-cover community pub), that difference is £52 per month. Goodtill costs £49. The maths work.

On the concurrent transactions test (two tills running simultaneously during peak), Goodtill handled it cleanly. No delays. Both staff processed payments without the system catching up to itself. That’s the difference between cloud architecture designed for hospitality and a POS system designed for coffee shops that happens to have a hospitality add-on.

Where Goodtill showed real strength:

• Built for pubs specifically — the menu design, button layout, and logic are pub-first
• Concurrent transactions handled smoothly even with three terminals
• Integrates with Vianet and other cellar management systems (crucial for tied pubs)
• Kitchen display system integration is robust
• Employee shift reports show exactly how long each staff member was logged in
• Better void/refund controls — useful for audit and compliance

Where Goodtill asked more of us:

• Initial setup took longer — about 3 hours to get menu structure, staff accounts, and till settings right
• Support is email-based, not phone-first (though responses are usually same-day)
• The upfront learning curve is steeper, but it flattens after two weeks
• Hardware is sold separately — you need to budget for iPad, card terminals, and receipt printer

One detail that mattered to me: Goodtill has a full review specific to the £49 per month offer and it’s genuinely what you get. No hidden tiers. That transparency matters when you’re running a tight operation.

Head-to-Head: What Actually Matters for Pubs

Here’s the comparison that matters. Not features, not price lists, but what happens when you’re under real pressure:

Payment Processing Speed Under Load

I ran a deliberate stress test: one staff member processing card payments while another completed split bills. 30 transactions across both tills, peak-time conditions.

• Square: Average 4.2 seconds per card transaction, with spikes to 8 seconds on concurrent transactions
• Goodtill: Consistent 2.1 seconds, no spikes
• SumUp (standalone): Decent hardware, but the EPOS logic (when used with other POS software) adds latency — 5.3 seconds average

On a 200-transaction Saturday night, that difference is real. Square costs you 10 minutes of bar service speed. Goodtill doesn’t.

Reporting and Compliance

At Teal Farm, I pass a 5-star EHO inspection and a Marston’s NSF audit (passed March 2026). Both require detail on staff accounts, voids, refunds, and reconciliation. My labour costs average 15% against the UK benchmark of 25-30% — not because I’m harsh, but because I track it precisely.

Square requires manual reporting to see staff labour as a percentage of takings. Goodtill shows it in real-time. That’s not a feature difference — that’s a business intelligence difference.

Integration with Pub Systems

If you’re a tied tenant (Marston’s, Heineken, Enterprise, etc.), your pubco specifies which payment processor you can use. Some pubcos won’t approve Square because they have their own payment agreement with a specific processor.

This is the hidden cost nobody mentions: if you install Square and your pubco won’t approve the payment processor, you’ve spent three weeks training staff on a system you now have to rip out. I know three licensees this happened to.

Goodtill’s SumUp processor is approved by most major pubcos. Even for Heineken’s Star Pubs tenants, SumUp is typically acceptable. Square often isn’t.

The Hidden Costs Beyond Monthly Fees

Here’s where most “free EPOS” articles fall short: they compare the headline price and miss the total cost of ownership.

Training and Lost Productivity

When I switched Teal Farm from our old system to testing new ones, I measured actual impact.

First week: staff confidence was 60%. They were slower. They made mistakes. I had to have a manager on the till more than usual. Estimated cost: 6% of normal takings.

Second week: confidence was 85%. Still slower than the old system, but workable. Estimated cost: 2% of normal takings.

Third week and beyond: performance matched the old system, then gradually exceeded it.

The true cost of switching EPOS systems is not £0 or £49 — it’s 8% of your takings for two weeks, plus staff frustration. This is true regardless of which system you pick. Build it into your decision.

Payment Processing Rates

Free systems use higher processor rates to offset the lack of subscription revenue:

• Square: 1.75% on card transactions
• Goodtill (£49/month): 1.49% on card transactions
• SumUp standalone: 1.99% (higher than both)

On £20,000 monthly takings with 85% card payments (typical for wet-led pubs), here’s the annual cost:

• Square: £4,335 in processing fees + £0 subscription = £4,335 annually
• Goodtill: £3,036 in processing fees + £588 subscription = £3,624 annually

Goodtill saves you £711 per year. That’s not marginal. That’s rent money.

Hardware and Setup

Honest comparison:

• Square: You probably already own an iPad. If not: iPad £329 + card reader £29 + receipt printer £200 = £558 upfront
• Goodtill: iPad £329 + SumUp card terminal £89 + receipt printer £150 = £568 upfront

Hardware cost is roughly equivalent. The difference is in what you can do with it.

Which System Should Your Pub Use?

After three months of real testing, here’s my clear recommendation:

Use Square if:

• You do fewer than 50 card transactions per day
• Your takings are under £3,000 per week
• You have one till and don’t need kitchen integration
• You’re not a tied tenant or your pubco approves Square explicitly
• You want absolute simplicity over optimisation

Square is genuinely good for micro-pubs and very small operations. But most pubs doing 180 covers — the premise of this guide — don’t fall into this category.

Use Goodtill (£49/month) if:

• You do more than 100 card transactions per day
• You need two or more tills running simultaneously
• You have kitchen integration requirements
• You’re a tied tenant and need processor flexibility
• You want real labour cost tracking for audit and compliance
• You want to avoid being locked into a payment processor

This is 80% of UK pubs doing real volume. Goodtill earns its £49 monthly fee inside the first three weeks through better processor rates and faster staff efficiency.

When to Consider Premium Systems Instead

If you’re multi-site, doing £100k+ monthly turnover, need cellar management integration, or operate as part of a group, look beyond free systems entirely. Our best pub EPOS systems guide covers ICRTouch, Epos Now, Tevalis, and others where free is actually a disadvantage because you’re paying for simplicity you don’t need.

One final reality: I use Pub Command Centre in addition to my EPOS system. The EPOS tells me what sold. Pub Command Centre tells me whether I made money — real-time labour %, VAT liability, cash position. That costs £97 once. The EPOS + proper backend analytics stack is what actually matters.

Before you commit to any system — free or paid — verify it works with your pubco’s approved payment processor. That single verification will save you weeks of grief.
