Cheapest POS systems in the UK for 2026 (with total monthly cost examples)

The cheapest POS companies in the UK for 2026, are POSApt, Clover UK, SumUp, Square and Zettle (PayPal Point of Sale). These providers publish transparent in-person transaction rates, which allows a meaningful total cost comparison.

If you define “cheapest” as the lowest total cost to operate — including software, hardware and merchant fees — then the most important factor is:

How much you process in card payments each month.

In UK hospitality, card payments typically account for the majority of revenue. That means merchant fees often outweigh subscription costs very quickly. A system that looks cheap because it has free software can become expensive if the transaction rate is high. On the other hand, a POS with a modest monthly fee can be significantly cheaper overall if the processing rate is low.

This article compares only providers where publicly stated UK in-person transaction rates are clear:

• POSApt: below 0.99% (card-present)
  
• Clover UK: up to 1.49%
  
• SumUp: 1.69% (in-person)
  
• Square: 1.75% (card-present)
  
• Zettle: 1.75% (card-present)

No speculative rates are included. Only clearly stated headline card-present pricing is used.

Published Base Pricing Overview (UK 2026)

Provider	POS Software (from)	Card-Present Rate	Contract Model
POSApt	£29 / month	Below 0.99%	Monthly
Clover UK	£9.99 / month	Up to 1.49%	Plan-based
SumUp	£0	1.69%	Pay-as-you-go
Square	£0	1.75%	Pay-as-you-go
Zettle	£0	1.75%	Pay-as-you-go

This table shows only clearly stated entry structures.

What “cheapest POS” really means in the UK

The real cost of a POS system includes three parts:

1) Software subscription

This may be £0, low monthly, or tiered depending on features.

2) Hardware

Tablet, terminal, printer, cash drawer, handheld devices.

3) Card processing fees

For most hospitality businesses, this becomes the largest cost line once sales grow.

In practical terms, once your card volume increases, the transaction rate matters more than the subscription fee.

How this comparison works

To avoid repeating multiple price tables throughout the article, the cost difference for each sales tier is explained once clearly in each scenario.

Assumptions used

• 85% of total revenue is card
  
• In-person card payments (chip & PIN/contactless)
  
• No refunds, chargebacks or Amex weighting included
  
• POSApt software assumed at £29/month
  
• Clover software assumed from £9.99/month
  
• SumUp, Square and Zettle assumed a £0/month base software for simplicity

These are realistic comparison assumptions for hospitality venues.

Scenario 1: Low Volume Venue

£8,000 monthly sales
Card volume at 85% = £6,800

Estimated monthly card cost

• POSApt (0.99%) → £67.32
  
• Clover (1.49%) → £101.32
  
• SumUp (1.69%) → £114.92
  
• Square (1.75%) → £119.00
  
• Zettle (1.75%) → £119.00

Adding base software (where applicable)

• POSApt total ≈ £96.32
  
• Clover total ≈ £111.31
  
• SumUp ≈ £114.92
  
• Square ≈ £119.00
  
• Zettle ≈ £119.00

What this means

At very low turnover, the gap between providers is smaller than many expect. Subscription-free models remain competitive. However, even here, the sub-1% rate still puts POSApt slightly ahead overall.

If your card volume stays below roughly £4,000–£5,000 per month, the savings difference narrows. Above that, the lower rate begins to pull ahead more clearly.

Provider	Card Fees	Software	Estimated Total Cost
POSApt	£67.32	£29.00	£96.32
Clover	£101.32	£9.99	£111.31
SumUp	£114.92	£0	£114.92
Square	£119.00	£0	£119.00
Zettle	£119.00	£0	£119.00

✅ Lowest total cost: POSApt

Scenario 2: Growing Venue

£25,000 monthly sales
Card volume at 85% = £21,250

Estimated monthly card cost

• POSApt (0.99%) → £210.38
  
• Clover (1.49%) → £316.63
  
• SumUp (1.69%) → £359.13
  
• Square (1.75%) → £371.88
  
• Zettle (1.75%) → £371.88

Including base software

• POSApt total ≈ £239.38
  
• Clover total ≈ £326.62
  
• SumUp ≈ £359.13
  
• Square ≈ £371.88
  
• Zettle ≈ £371.88

What this means

This is where merchant rate becomes decisive.

The difference between 0.99% and 1.75% is 0.76%.

On £21,250 card volume, that equals £161.50 per month in processing difference alone.

At this level, a lower rate dominates subscription differences. Even if a competitor has free software, the higher processing rate outweighs it.

For most independent cafés, takeaways and casual dining venues, this turnover range is common. At this level, the lowest transaction rate is usually the cheapest overall solution.

Provider	Card Fees	Software	Estimated Total Cost
POSApt	£210.38	£29.00	£239.38
Clover	£316.63	£9.99	£326.62
SumUp	£359.13	£0	£359.13
Square	£371.88	£0	£371.88
Zettle	£371.88	£0	£371.88

✅ Lowest total cost: POSApt

Scenario 3: Busy Hospitality Site

£60,000 monthly sales
Card volume at 85% = £51,000

Estimated monthly card cost

• POSApt (0.99%) → £504.90
  
• Clover (1.49%) → £759.90
  
• SumUp (1.69%) → £861.90
  
• Square (1.75%) → £892.50
  
• Zettle (1.75%) → £892.50

Including base software

• POSApt total ≈ £533.90
  
• Clover total ≈ £769.89
  
• SumUp ≈ £861.90
  
• Square ≈ £892.50
  
• Zettle ≈ £892.50

What this means

At higher turnover, the processing rate gap becomes significant.

The 0.76% difference between 0.99% and 1.75% equals:

£51,000 × 0.0076 = £387.60 per month

That is over £4,600 per year.

At this stage, even small percentage differences create large annual savings. For busy venues, merchant rate is almost always the biggest controllable cost inside a POS decision.

Provider	Card Fees	Software	Estimated Total Cost
POSApt	£504.90	£29.00	£533.90
Clover	£759.90	£9.99	£769.89
SumUp	£861.90	£0	£861.90
Square	£892.50	£0	£892.50
Zettle	£892.50	£0	£892.50

✅ Lowest total cost: POSApt

Ranking by Total Cost Logic (Based Only on Clear Public Rates)

1) POSApt

The combination of a modest monthly plan and sub-1% card rate means it consistently produces the lowest total cost in all three turnover scenarios above, assuming the rate applies as advertised.

Who it suits

• Card-dominant hospitality businesses
  
• Operators focused on reducing long-term processing cost
  
• Growing venues expecting turnover increases

Where to verify

• Confirm exact rate eligibility
  
• Confirm online vs in-person rate differences
  
• Confirm no additional mandatory charges

If the sub-0.99% rate applies cleanly, it is mathematically the cheapest across low, mid and high turnover once card payments are meaningful.

2) Clover UK

At up to 1.49%, Clover sits between sub-1% and the 1.69–1.75% range. It performs noticeably better than SumUp, Square and Zettle at higher volumes.

Who it suits

• Smaller restaurants
  
• Operators wanting a payment-led bundle
  
• Businesses comfortable with structured plans

At mid-to-high turnover, 1.49% still leaves a significant gap compared to 0.99%, but it improves considerably over 1.69%+ providers.

3) SumUp

Simple 1.69% rate. No complicated tiers. Strong for small operators.

At mid-level and higher turnover, the 1.69% rate results in hundreds of pounds per month more than sub-1% options.

4) Square

Easy onboarding and strong ecosystem. However, 1.75% card-present rate makes it less competitive as turnover rises.

Best suited for

• Startups
  
• Low-volume counter service
  
• Businesses prioritising simplicity over long-term rate optimisation

5) Zettle (PayPal Point of Sale)

Why it ranks alongside Square
Clear 1.75% card rate. Similar total cost structure to Square in practical terms.

Best suited for

• Small independent operators
  
• Businesses already using PayPal tools

When the Cheapest Option Changes

There are situations where the lowest advertised rate may not automatically equal cheapest overall:

Very low turnover

If card sales are minimal, subscription costs can outweigh rate savings.

Heavy online payment mix

Online rates may differ from in-person rates. Always compare correctly.

Short-term or temporary trading

Market stalls or pop-ups may prioritise flexibility over marginal rate savings.

Negotiated custom rates

Some providers adjust rates for higher turnover businesses.

Be Aware of Extra Costs Beyond the Base Price

When comparing the cheapest POS systems in the UK for 2026, the headline card rate and monthly subscription are not always the full cost. Some providers separate advanced tools and support tiers into paid add-ons, while others include core functionality within the base subscription.

Understanding what is included helps you avoid unexpected monthly increases.

POSApt

POSApt presents its POS subscription as including core features and standard ongoing support.

Included in the base plan:

• Core POS functionality
  
• Sales and reporting tools
  
• Product and menu management
  
• Standard hospitality workflows
  
• Ongoing software updates
  
• Standard support

There is no publicly advertised separate charge for essential features or standard support. Hardware and optional third-party integrations are separate, but core POS functionality appears included within the subscription.

This makes pricing more predictable, especially for hospitality businesses that want full functionality without stacking paid modules.

Clover UK

Clover includes basic support with an active subscription, but operates an app marketplace model.

Included:

• Core POS functions
  
• Basic support

Potential additional costs:

• Paid apps for advanced reporting
  
• Loyalty systems
  
• Payroll or workforce tools
  
• Additional feature modules

Clover can remain affordable at base level, but total cost may increase if advanced apps are added.

SumUp

SumUp includes standard support and core POS functionality.

Included:

• Basic POS tools
  
• Standard support

Possible extra costs:

• Priority or business-level support upgrades
  
• Feature upgrades beyond the core POS

The structure is simple, but advanced tools may require paid upgrades.

Square

Square includes basic POS functionality and standard support.

Included:

• Entry-level POS features
  
• Standard support

Potential additional costs:

• Paid hospitality-specific tiers
  
• Advanced team management tools
  
• Loyalty programs
  
• Premium reporting
  
• Priority support options

Square’s ecosystem is flexible, but advanced features are typically unlocked through paid plans.

Zettle (PayPal Point of Sale)

Zettle includes basic POS tools and standard support.

Included:

• Core sales functionality
  
• Basic reporting
  
• Standard support

Potential additional costs:

• Advanced integrations
  
• Expanded reporting
  
• Optional service upgrades

Costs may vary depending on configuration and partner arrangements.

What This Means for Total Cost

All providers include basic support. The main difference is how advanced functionality is structured.

• POSApt appears to include core features within the subscription.
  
• Clover and Square commonly separate advanced tools into paid add-ons or higher tiers.
  
• SumUp and Zettle offer simple base functionality with optional upgrades.

When calculating the cheapest POS system in the UK for 2026, always confirm:

• What features are included in the base plan
  
• Whether advanced reporting or loyalty is extra
  
• Whether premium support carries a fee
  
• What hardware costs apply

This ensures your total monthly cost reflects reality rather than just the headline processing rate.

Support & Feature Costs (UK 2026) — Updated

Provider	Basic Support Included	Paid Priority Support	Advanced Features/Add-Ons
POSApt	Yes	No known separate fee	Core features included
Clover UK	Yes	Possible	Advanced features often paid
SumUp	Yes	Yes	Optional feature upgrades
Square	Yes	Yes	Paid advanced tiers & add-ons
Zettle	Yes	Possible	Optional upgrades/integrations

Final Verdict

Based strictly on clearly published UK in-person transaction rates and reasonable software assumptions:

POSApt ranks as the cheapest overall in most hospitality scenarios if the sub-0.99% rate applies without hidden add-ons. The software includes full POS features and no separate cost for support.

Clover follows as a mid-range processing alternative.

SumUp, Square and Zettle remain competitive for low-volume or startup operators but become more expensive as turnover increases.

The cheapest POS system in the UK in 2026 is not the one with free software. It is the one with the lowest effective merchant cost relative to your actual card volume.
