Square vs Epos Now: When Free Becomes Expensive

Last updated: 23 April 2026

A free EPOS system sounds like the obvious choice until your card reader dies mid-service on a Saturday night and your team has no backup. Most pub operators compare Square vs Epos Now by looking at monthly fees alone — but that’s exactly where the real cost lives invisible. You’re choosing between a system that charges nothing upfront but makes money through payment processing, and one that locks you into a 24-month contract with transparent but substantial monthly fees. The difference isn’t just price; it’s reliability, staff training time, and what actually happens when three staff are processing payments simultaneously during last orders. This guide breaks down both systems the way I’d explain them to a fellow licensee — based on real-world pub trading, not a spreadsheet comparison. You’ll understand the hidden costs both systems carry, which one actually works for wet-led venues like ours, and why choosing wrong can cost you thousands in lost sales and staff frustration.

The Free Trap: How Square Makes Money When You Don’t

Square’s free tier sounds perfect: no monthly fee, no contract, no setup cost. In reality, free EPOS systems don’t exist — they just shift the cost to where you’ll pay it without realising. Square makes its money from payment processing: 2.5% of every card transaction plus 20p per transaction, or 3.5% plus 20p for online payments.

Let me put numbers on this. At Teal Farm, a typical Saturday during rugby season does around £3,000 in bar takings. If 85% goes on card (which is now standard for UK pubs), that’s £2,550 in card payments. Square’s fee on that: 2.5% of £2,550 = £63.75, plus 20p per transaction. On 50 transactions, that’s an additional £10. Single Saturday: £73.75. Across a year, if we assume that’s typical for 40 trading weeks, you’re paying Square roughly £3,000 just in processing fees — and you’ve paid nothing for the till itself.

That doesn’t sound terrible until you compare it to what you’d actually spend on Epos Now, and realise you’re comparing apples to oranges. The hidden cost isn’t just the payment processing; it’s the fact that you’re locked into Square’s payment processor, and you have no leverage to negotiate rates. If Square decides to increase rates (they have done this before), you either accept it or spend two weeks retraining staff on a new system.

There’s also the reliability question. Square is built for retail — simple single-terminal shops that process one transaction at a time. Pubs run multiple payment terminals, kitchen tickets, bar tabs, and split bills simultaneously. During a match day at our pub with 180 covers, you need rock-solid uptime and multi-terminal reliability. Square’s track record for pubs under pressure shows it can struggle with concurrent transactions. You don’t notice this in a quiet Tuesday afternoon demo — you notice it when four staff are hitting the same payment system during the last 30 minutes of service.

Epos Now’s Real Cost: Payment Processing and Contract Lock

Epos Now charges between £99 and £179 per month, depending on the package and number of terminals. That’s visible, predictable, and you know exactly what you’re paying. But that’s not the full story.

On top of the monthly software fee, you still pay payment processing charges. Epos Now partners with various payment processors (Worldpay, Sageblue, others) and the rates typically sit at 1.5%–2.4% per transaction plus 20p, depending on your merchant category and volumes. This is actually better than Square’s 2.5%, but the difference only matters if you’re processing high volumes. For most wet-led pubs, you’ll save £20–£40 per month on processing, which is roughly £240–£480 annually. That’s meaningful.

The real objection to Epos Now isn’t the cost — it’s the 24-month contract. You’re committed, and if the system doesn’t work for your pub or your pubco doesn’t approve the payment processor, you’re stuck paying until the contract ends or you breach and face penalties. This is why verification before signing is absolutely critical.

I know licensees who signed an Epos Now contract without checking with their pubco first and discovered their tied-house agreement only allows specific payment processors. Three months in, they had to switch systems anyway and pay early termination fees. That cost them roughly £600 just to get out of a bad decision. Before comparing Square vs Epos Now, call your pubco and ask which payment processors are approved in your tenancy. This single call saves thousands in mistakes.

That said, if your pubco approves Epos Now’s payment partner, the system is rock-solid for pub operations. We’ve tested it during peak service and it handles multi-terminal, concurrent payment processing without the lag you see on some free systems.

Peak Trading Reality: Where Systems Actually Fail

Both Square and Epos Now look excellent in a quiet demo. The real test is Saturday night at 10:45 PM with a full house, card-only payments, kitchen tickets backing up, and bar tabs running across three terminals simultaneously.

This is where I tested both systems at Teal Farm before making our decision. Here’s what I learned: most EPOS systems that look good in a demo struggle when three staff are hitting the same terminal during last orders, especially if you’re running split bills or tabs.

Square’s free platform showed noticeable lag during high-volume service — 2–4 second delays between tapping a card and the transaction processing. That doesn’t sound like much until you multiply it by 40 transactions in the final 30 minutes. You’re looking at 3–4 minutes of cumulative lost time per night, which directly impacts your ability to serve customers before closing time. Staff frustration follows, then mistakes (over-ringing, lost payments, customer refunds).

Epos Now handled the same scenario with minimal lag — under 1 second per transaction. The difference becomes obvious during a busy Tuesday quiz night when you’ve got walk-ins at the bar, quiz score updates on kitchen tickets, and regular customers paying tabs. You can feel the difference in staff speed and accuracy.

This is the unpublished cost of choosing the wrong system: lost trading time, staff stress, and customer perception. A customer waiting 30 seconds for their card to process remembers that experience. Over a month, these small delays compound into measurable lost takings.

Integration and Pubco Compatibility: The Approval Nightmare

Here’s what no generic comparison site tells you: your pubco’s payment processor requirements override your EPOS choice. Many tied houses and managed pubs have exclusive agreements with specific payment processors. If you install an incompatible system, you’re technically breaching your tenancy agreement.

This applies more to Epos Now than Square, because Epos Now requires you to use their approved payment partners. Square is more flexible — it works with most payment processors — but it’s still worth verification.

I had to call Marston’s (our pubco) before evaluating any system and confirm which payment processors I was allowed to use. The answer: Worldpay, Sageblue, and PayPal Here. It narrowed my options significantly. If I’d signed an Epos Now contract with a non-approved payment partner and discovered this later, I’d have been liable for early termination costs.

Check this before you demo anything. Call your pubco licensing team or consult your tenancy agreement directly. Most will list approved payment processors in the tender section or the POS appendix. It takes 10 minutes and saves weeks of frustration.

Beyond payment processing, integration with existing systems matters. Stock management and cellar integration are critical for tied tenants managing linked inventory. Epos Now integrates directly with most major cellar systems. Square’s free plan does not. If you’re running inventory through a third-party system (many managed pubs do), Square might create duplicate data entry.

Staff Training and Changeover Costs

Here’s the cost nobody puts in the calculator: 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.

When you switch from your current till (or from another EPOS) to either Square or Epos Now, your staff speed drops by roughly 40–60% for the first 10 working days. They know the old system; they’re learning the new one. Transactions that took 45 seconds now take 75 seconds. During a quiet Tuesday, this is fine. During a Friday night with a queue at the bar, this directly reduces throughput and customer satisfaction.

I’ve run the numbers. At Teal Farm, our peak trading periods (Friday/Saturday) account for roughly 35% of weekly takings across 40% of trading hours. A 40% drop in staff speed during the changeover period costs roughly £150–£200 in lost takings per night, or £750–£1,000 across the first two weeks of implementation. That cost applies whether you choose Square or Epos Now.

Both systems offer training — Epos Now provides onsite training as part of their package, while Square relies more on video tutorials and support documentation. Epos Now’s approach is better for pubs with higher staff turnover, because the formal training session means new hires can be trained by your existing team rather than you teaching everyone individually.

To minimise this cost, implement changeover during a quieter trading period (Monday–Thursday, or early January when pubs traditionally run quieter). Never switch systems during peak season. The £500 savings you’d get by delaying changeover until January is worth far more than the £150 lost takings you save by implementing in November.

Which System Wins for Your Pub Type

This is where the decision becomes clear, because wet-led pubs have completely different EPOS requirements to food-led pubs — and most comparison sites miss this entirely.

For Wet-Led Pubs (Bar-Focused, Limited Food)

Epos Now wins, assuming your pubco approves their payment processor. Here’s why: wet-led venues need multi-terminal reliability under peak load, minimal payment processing lag, and straightforward bar tab management. Epos Now handles all of this without the stress. The monthly fee (£99–£149) is worth the peace of mind during match days and busy quiz nights.

Square works for a very quiet wet-led pub with low staff numbers and predictable payment volumes. But most wet-led venues have Saturday nights that exceed Square’s comfortable operating threshold. The false economy of free kills you during peak service.

For Food-Led Pubs (Kitchen-Heavy Operations)

The choice depends on your kitchen volume and table-service complexity. Square actually performs better for food-led venues than wet-led pubs, because food service is less payment-intensive and more forgiving of slight processing delays. If you’re doing 60% food and 40% wet, Square becomes more viable. You’re generating takings through covers and check average rather than volume of transactions, which suits Square’s strength.

Epos Now is still the safer choice, but Square’s cost advantage (£0 monthly vs £99+) becomes more attractive for food-led venues with lower transaction volumes.

The Hybrid Venue (Wet and Food)

Teal Farm fits this category — we do wet sales, quiz nights, and match day food service simultaneously. For this scenario, evaluate systems based on their real-world multi-terminal performance, not their feature list. Square sounds great in the demo. In practice, during a busy Saturday with food orders backing up and 80 covers at the bar, the lag becomes noticeable and frustrating for staff.

Use your current year’s profit data to calculate true EPOS cost. Take your annual card processing revenue, multiply by 2.5% (Square’s rate), and compare to Epos Now’s monthly fee times 12, plus their payment processing rate times the same revenue. Use a pub profit margin calculator to factor in the staff training downtime and lost takings during changeover. That gives you the real financial comparison, not just the headline numbers.

Payment Processing: The Hidden Monthly Cost

Neither system is truly free once you include payment processing. Here’s the breakdown for a typical wet-led pub doing £2,500–£3,500 per week in card takings:

Square: £0 software + 2.5% processing + 20p per transaction. Weekly cost: £62–£87 in processing alone. Annual: £3,200–£4,500.

Epos Now: £99–£149 monthly software + 1.5%–2.4% processing + 20p per transaction. Weekly cost: £45–£75 in combined fees. Annual: £2,800–£3,900.

The numbers are closer than they appear at first glance. Epos Now’s contract commitment is the real differentiator, not the cost. You’re paying slightly less for Epos Now, but you’re locked in for 24 months. Square costs slightly more, but you can walk away monthly. That optionality has value if your trading circumstances change or if the system underperforms.
