## Key takeaways

- Card processing is now the third-largest restaurant operating expense behind food and labor, and 66% of US operators saw processing fees rise over the past two years, by an average of 9.4% (National Restaurant Association).
- The Durbin Amendment caps debit-card interchange at 21 cents plus 0.05% of the sale, but only for banks holding over $10 billion in assets, and it has never applied to credit-card interchange at all (Federal Reserve).
- UK and EU law caps the interchange fee itself at 0.2% on debit and 0.3% on credit, yet the scheme and processing fees layered on top of that cap rose at least 25% since 2017, adding upwards of £170 million a year in cost across UK businesses (Payment Systems Regulator).
- Toast's own Capterra page shows a 4.1-out-of-5 average across 553 verified reviews, and processing fees plus unexpectedly costly integrations are the complaint themes that repeat most (Capterra).
- On $10,000 of monthly card sales, cutting your effective processing rate from 1.8% to 1.0% is worth $960 a year. Put your own numbers into the calculator below and see what your contract is actually costing you.

Compare POS vendors on the monthly software fee alone and you will pick the wrong system almost every time, because the software fee is the smallest of the three costs that matter. **Card processing is now the third-largest operating expense for a US restaurant, behind only food and labor, and 66% of operators say their processing fees rose over the past two years by an average of 9.4%**, according to the National Restaurant Association's own swipe-fee research. The two costs that decide whether a POS system is actually cheap, the processing rate and the contract you sign to get it, rarely show up on the pricing page you compare before buying.

This guide breaks the total cost of a POS system into the three layers an independent cafe, bar, or restaurant needs to price before signing anything: the published subscription and hardware fees, the card-processing stack that sits underneath every sale, and the contract terms that decide what it costs you to leave. Super44 does not sell or resell POS hardware, so none of this is a pitch for one system over another; it is the arithmetic a sales call skips.

## The subscription fee is the layer you can already compare

**Software subscriptions for independent-venue POS systems in the US and UK run from free to around $400 a month, and the gap between vendors is smaller than the marketing suggests.** Square's entry tier is free, with paid Plus and Premium plans at $49 and $149 a month buying lower processing rates and more back-office features. Lightspeed's Restaurant line runs Starter at $69, Essential at $189, and Premium at $399 a month, with a kitchen display screen adding $30 a month per screen on top. SumUp's UK pricing starts at £0 with pay-as-you-go processing, or £19 a month on its Payments Plus plan, which lowers the card rate instead of adding features.

**Published software subscription tiers, independent-venue POS systems (monthly, before hardware or processing)**

| Vendor | Entry tier | Mid tier | Top tier |
| --- | --- | --- | --- |
| Square (US) | $0 | $49 | $149 |
| Lightspeed Restaurant (US) | $69 | $189 | $399 |
| SumUp (UK) | £0 | £19 | - |

*Source: vendor pricing pages, checked July 2026 (Square, Lightspeed, SumUp - see sources). Excludes hardware purchase or lease and payment processing rates, which are compared separately below.*

None of this tells you what a single card transaction costs, which is where the real gap between vendors opens up.

## The card-fee stack most buyers never unpack

**Every card payment you take moves through three separate fees, and only one of them is capped by law.** The interchange fee goes to the customer's card-issuing bank, the scheme fee goes to Visa or Mastercard for running the network, and the acquirer or processor fee goes to whoever handles your payments, often the POS vendor itself. Buyers who compare "our rate is 1.6%" between two vendors are usually comparing different splits of the same three-part stack, not a genuinely different cost structure.

In the US, only the first of those three fees has a legal ceiling, and even that ceiling has a large exception. The Durbin Amendment, enacted as part of Regulation II, caps debit-card interchange at 21 cents plus 0.05% of the transaction value for banks holding over $10 billion in assets. Two things about that cap matter more to an independent operator than the exact number: it exempts every bank and credit union below the $10 billion threshold, so a debit card issued by a smaller regional bank can legally carry a higher interchange fee, and it applies to debit cards only. Credit-card interchange in the US carries no federal cap at all, which is the main reason credit transactions typically cost a venue more per pound or dollar of sale than debit. The cap itself is also currently being contested in court, and while a 2025 ruling ordered it vacated, that ruling is stayed pending appeal, so the 21-cent-plus-0.05% ceiling remains the law you actually operate under today.

## The UK and EU cap that doesn't cap what you pay

**UK and EU law caps interchange at 0.2% on debit cards and 0.3% on credit cards, but the fees layered on top of that cap have grown faster than the cap has controlled anything.** The Interchange Fee Regulation, in force since December 2015 and retained in UK law after Brexit, sets those percentages as a ceiling on the fee paid to the card issuer. It says nothing about the scheme fee or the acquirer's own margin, and the UK's Payment Systems Regulator found that Visa and Mastercard's own scheme and processing fees to acquirers rose by at least 25% since 2017, adding more than £170 million a year in extra cost across UK businesses. The regulator's own market review is direct about the scale of it: the fee increases are "costing businesses at least £170million extra per year," a cost the interchange cap does nothing to touch because it only governs the fee paid to the card issuer, not the scheme or acquirer layers on top.

There is a second gap worth knowing about if you take card-not-present payments (online or phone orders) from EU-issued cards: the interchange cap only applies when the merchant, the card issuer, and the payment processor are all inside the UK. UK-EEA card-not-present transactions fall outside that cap, and the Payment Systems Regulator's own review found Visa and Mastercard raised those specific rates roughly fivefold after Brexit, debit from 0.2% to 1.15% and credit from 0.3% to 1.5%, adding an estimated £150-200 million a year in extra cost to UK businesses.

**Interchange fee cap vs. cross-border rate on EU-issued cards, UK merchants**

|  | Value |
| --- | --- |
| Domestic UK debit (capped) | 0.2% |
| Domestic UK credit (capped) | 0.3% |
| Cross-border EU debit (card-not-present) | 1.15% |
| Cross-border EU credit (card-not-present) | 1.5% |

*Source: UK Payment Systems Regulator, market review into cross-border interchange fees. The card-not-present cross-border rates are not capped because the IFR only applies when merchant, issuer, and acquirer are all within the UK.*

None of this means the caps are meaningless. It means a quoted "0.3%" rate almost never describes what actually lands on your statement, in the UK, the EU, or the US, because interchange is one line of a three-line bill.

## What operators say once they've already signed

**Toast's own Capterra page, the review platform Toast links from its marketing site, shows a 4.1-out-of-5 average across 553 verified reviews, and processing fees plus unexpectedly costly integrations are the complaint themes that repeat most often.** A star rating this public is a useful cross-check against a sales demo precisely because it comes from people already using the system day to day, not from a pitch.

The clearest public example of a POS vendor misjudging what operators would tolerate came in 2023, when Toast added a 99-cent fee to customer-facing online orders over $10. The backlash was strong and immediate enough that Toast reversed the fee within about a month. On the company's Q2 2023 earnings call, CEO Chris Comparato called it a "mistake." The episode is three years old now, but it is a clean illustration of a pattern that hasn't gone away: fees introduced quietly, discovered by operators in production, and only reversed once the discovery became a public cost to the vendor rather than a private one to the venue. A smaller competitor, GoTab, has run a transparent 25-cent-plus-1% fee on QR-code ordering since 2019 specifically to keep the card-not-present cost premium visible rather than absorbed and later added back.

## The contract clauses that turn switching into a project

**The mechanism that makes POS switching expensive almost never appears on the pricing page: minimum contract terms with automatic renewal clauses, which convert a monthly software fee into a multi-year commitment the moment you sign.** Independent comparisons of POS vendor contracts consistently describe the same pattern across the industry: an initial term of two to three years, an automatic renewal into a further term unless you give notice inside a specific window, and hardware that is financed or leased rather than owned outright, which means it can still be a live liability even after you stop using the system. None of that is illegal or even unusual; it is standard subscription-contract architecture. The problem is that almost nobody reads it before the sales call ends, because the conversation is framed around the monthly number, not the exit terms.

Before signing anything, get four answers in writing, not verbally from a sales rep:

1. **The minimum term, in months**, not "annual" or "standard", the actual number.
2. **Whether the contract auto-renews**, and exactly how much written notice you must give to stop it, and by when.
3. **Who owns the hardware** if you paid it off, financed it, or are renting it monthly, and what happens to the balance if you cancel early.
4. **What format your sales, menu, and customer data export in**, and whether that export still works after you've closed your account, not just while it's active.

Toast's own developer documentation confirms what a working system can export while your account is active: order, payment, labor, and menu configuration data, generated on a same-day cadence. What it does not address, in the documentation available publicly, is whether that same export access survives account cancellation, a genuine gap rather than an assumption, and exactly the kind of question that belongs in your contract review, not your onboarding call.

## What would switching actually cost you?

Two numbers decide most of the answer: how much your processing rate would actually change, and how many months are left on your current contract's minimum term. Put your own figures in.

**What a lower processing rate is actually worth you** *(interactive calculator in the web version)*

Example (Monthly card sales: 15,000 $, Current effective processing rate: 2 %, Rate you have been offered elsewhere: 1 %, Remaining contract cost + hardware you would forfeit: 800 $):

- Saved per month on processing: 120 $
- Saved per year on processing: 1,440 $
- Months to recover your exit cost: 7  months

*Straight arithmetic on the numbers you enter. It does not include migration time, staff retraining, or revenue disruption during a changeover, all of which are real costs worth pricing separately before you decide.*

The number this calculator cannot give you is the time and disruption cost, staff retraining hours, a week of slower service while everyone relearns the till, orders keyed wrong during the changeover. Those costs are real and specific to your venue, and no comparison site prices them for you, which is exactly why they get left out of the decision.

## Buying without locking yourself in again

The venues that avoid getting stuck are not the ones that pick the cheapest system; they are the ones that price the exit before they price the entry. That means asking for the minimum term and cancellation notice in writing before you sign, checking whether the hardware is yours or the vendor's, and getting a straight answer on what your own sales history looks like the day after you leave, in a format you can actually load into whatever you switch to next.

The same discipline applies to what you do with the data once it's flowing. One large riverside restaurant now runs its entire week off a single Monday-morning report: revenue, top and flop products, table turns, and fresh reviews. The point of a POS system was never the till, it was always the data underneath it, and a good decision protects your ability to use that data regardless of which badge is on the screen. For labour costs and the calculations that sit next to your processing bill on the same P&L, see our [restaurant labour cost benchmarks](/blog/restaurant-labour-cost-percentage); if tips flow through the same terminal, our [tronc scheme guide](/blog/uk-tronc-scheme-guide) covers the UK-specific payroll side of that stack.

## FAQ

### What does it actually cost to switch POS systems?

There is no single published figure, and most of the numbers circulating online come from vendor marketing rather than independent research. The real total sits across four categories worth pricing individually before you decide anything - any early termination fee left on your current contract, what you lose if your current hardware does not work with the new system, the cost of exporting and re-entering menu and customer data, and the hours it takes to reconnect accounting, payroll, or delivery integrations.

### Does the Durbin Amendment cap credit card processing fees?

No. The Durbin Amendment (Regulation II) only caps debit-card interchange, at 21 cents plus 0.05% of the transaction for banks with over $10 billion in assets, and even that cap does not apply to smaller community banks and credit unions. Credit-card interchange in the US has no federal cap at all, which is why credit processing typically costs a venue more than debit.

### If the EU and UK cap interchange fees, why do card fees keep rising?

The 0.2%/0.3% cap under the Interchange Fee Regulation only covers the fee paid to the cardholder's bank. Card schemes and payment processors charge separate fees on top of that, and the UK's Payment Systems Regulator found those scheme and processing fees rose at least 25% since 2017, adding more than £170 million a year in cost to UK businesses. The cap controls one layer of a three-layer fee stack.

### What should I check before signing a POS contract to avoid getting locked in?

Ask for the minimum term in months, whether the contract auto-renews and how much notice you must give to stop it, whether you own the hardware outright or are financing/leasing it, and exactly what data format the vendor will export your sales and customer history in if you leave. Get all four answers in writing before you sign, not after.

### Is it cheaper to buy hardware outright or rent it monthly?

It depends on how long you expect to keep the system. Monthly hardware rental (commonly £20 to £40 per terminal in the UK, once you include add-ons like printers and card readers) avoids a large upfront bill but keeps you paying indefinitely and rarely lets you walk away with equipment you can resell or reuse. Buying outright costs more on day one but the equipment is yours if you switch software providers later, provided the new system supports it.

### Are review sites like Capterra a reliable way to judge a POS vendor?

They are a useful, verifiable data point, not the whole picture. Toast's Capterra page, for example, shows a 4.1 out of 5 average across 553 verified reviews, with processing fees and integration costs the most repeated complaints. Star ratings are shaped by who bothers to leave one, so treat them as a prompt to ask pointed questions in a demo, not as a final verdict.
