SumUp Reviews: Pros, Cons and What the Fees Really Cost
SumUp reviews are mostly positive: aggregators report Trustpilot approval between 80% and 90%, with the rest focused on disputes, refunds and account freezes. The weak point is not reliability but the single blended rate of 1.95%, opaque on the real per-transaction cost. This guide collects pros, cons and numbers so you can decide.
SumUp blended rate versus RoxPay IC++ pricing (estimated monthly cost)
| Offer | €2,000/month | €5,000/month | €20,000/month |

What SumUp reviews actually say
The aggregated picture is fairly consistent across sources. On the Italian market, aggregators like Alverde (2024) report over 80% of Trustpilot customers rating SumUp exceptional or very good, with around 13% reporting problems; Selectra cites positive shares above 90%, with negatives around 6%. In the UK, Trustpilot stays majority positive, but negative threads are louder and more detailed.
The criticism concentrates on three areas: chargeback and refund handling with long resolution times, temporary holds on funds during anti-fraud checks, and support that is hard to reach by phone. Evidence comes from a 2025 Reddit thread on r/smallbusiness with over thirty comments and a share of App Store reviews. For the cost side of these discussions, [the SumUp fees comparison](/en/resources/sumup-fees-roxpay-comparison) puts the numbers side by side.
Pros: where SumUp performs well
The strengths repeated across positive reviews are concrete. No monthly fee: no subscription and no contractual lock-in, valued by businesses with low card volume. Fast sign-up: online onboarding within a day, no bank-style application process. Cheap hardware: readers from tens of pounds, bought outright instead of rented. Simplicity: app and terminal designed for non-technical users; the startups.co.uk review (2026) reports a battery rated for over a thousand transactions per charge.
These are real advantages for a specific profile: low-volume activities, new shops and market traders who want to start selling on the same day without fixed costs.
Cons: the limits reviewers keep hitting
The first limit does not show up in star ratings but in the contract: the blended rate of 1.95% mixes interchange, scheme fees and provider margin into one opaque percentage, so you cannot see what each card type really costs. A business taking many premium credit cards pays the same rate as one taking only debit cards, despite very different network costs.
The second limit is disputes: negative reviews on Trustpilot, Reddit and the App Store converge on slow refunds, temporary fund freezes during checks and slow support channels, especially by phone. The third limit is structural: with a single flat rate there is nothing to negotiate, while an independent gateway lets you attack the largest cost component, the markup. The [SumUp fees comparison](/en/resources/sumup-fees-roxpay-comparison) documents the gap item by item.
What it really costs: blended versus IC++
The comparison is about transparency, not only the headline percentage. With a blended rate of 1.95%, a business taking 10,000 pounds per month pays 195 pounds without knowing how much of that is interchange, scheme fee or margin. With RoxPay IC++ pricing you pay €0.15 + 0.35% to 0.85% (IC++), with interchange and scheme fees shown at real cost on the statement.
Since Brexit the EU interchange caps no longer apply to UK acquiring, so blended rates can hide wider markups on premium cards. For a typical mix dominated by debit, the annual difference between the two models is measured in hundreds of pounds and grows with volume.

Who SumUp suits and who should look elsewhere
SumUp makes sense where volume is occasional and simplicity outweighs cost: markets, sporadic sales, early-stage shops testing demand. In those cases the flat rate is the price of convenience, and positive reviews confirm it.
For businesses with regular takings the maths changes: at constant volume the blended component weighs every month, and the ability to negotiate or reduce the markup is worth more than instant activation. Professionals with mid-size tickets and off-site payments have hardware-free alternatives too, as the phone POS guide explains. The right choice starts from one number: your real card mix, month by month, at the effective cost of every transaction.
Frequently Asked Questions
Is SumUp good and reliable?
Yes on the regulatory side: SumUp operates as an authorised payment institution and aggregators report Trustpilot approval ratings between 80% and 90%.

No monthly fee: SumUp charges no subscription but applies a blended rate of 1.95% per card transaction plus paid hardware starting from tens of pounds. With RoxPay IC++ pricing you pay €0.15 + 0.35% to 0.85% (IC++), with every component shown at real cost.
What problems do reviewers report with SumUp?
Negative reviews converge on three themes: slow chargeback and refund handling, temporary holds on funds during security checks, and hard-to-reach phone support. A 2025 Reddit thread on r/smallbusiness with 30+ comments collects dozens of similar reports from UK small businesses.
