Comparison · Updated September 18, 2026
A pay-as-you-go card reader and POS provider with flat published rates, no monthly fee and no contract. Strong for small and mobile sellers; the recurring complaint is account freezes and held funds with slow resolution.

myPOS is a London-headquartered payments company founded in 2012 by Christo Georgiev and owned since February 2024 by the private-equity firm Advent International in a deal reported at around €500 million, after which the founder exited and Mario Shiliashki, formerly of Mastercard and PayPal, became chief executive. It sells card machines outright — the myPOS Go 2 at £39, Flex at £59, Go Combo at £169 and Ultra at £179, all excluding VAT — with no monthly fee, and settles every card payment instantly into a free myPOS e-money business account with a Mastercard business card, a model it says it pioneered in 2014. The UK rate card is published for businesses under £10,000 a month: 1.10% + 7p on domestic consumer cards, 2.20% + 7p on EEA consumer cards, 2.45% + 7p on American Express and 2.85% + 7p on everything else in person, and 1.30% + 15p domestic, 2.50% + 15p Amex and 2.90% + 15p other cards online; larger businesses get a custom quote. UK, Gibraltar and Swiss services are provided by myPOS Payments Ltd, an electronic money institution authorised by the Financial Conduct Authority (reference 900826), and the group says it serves more than 400,000 merchants in over 30 countries with 15 physical stores, up from the 170,000 small businesses Reuters reported when the sale was agreed. Its Trustpilot profile is 4.2 from nearly 22,000 reviews, 70% five-star and 13% one-star, and the one-star reviews are about unexplained application rejections, slow deliveries and support that is hard to reach.
SumUp and myPOS are the two pay-as-you-go card machines a UK sole trader or small shop is most likely to weigh, and both are London-based, FCA-authorised e-money institutions with no contract and no monthly fee. They price in opposite ways. SumUp (a B+ on Payment Review) charges a flat 1.69% on every in-person card — domestic, EEA, Amex, business cards alike — and 2.5% online, and pays out free to any UK bank account in one to two business days, or by 7am the next day into its own Business Account. myPOS (a B) charges 1.10% + 7p on domestic consumer cards in person and 1.30% + 15p online, but 2.20% + 7p on EEA cards, 2.45% + 7p on Amex and 2.85% + 7p on business and non-EEA cards, settles every payment into its e-money account within seconds, and charges £1.50 to move money to your bank. On a domestic consumer card the two cost the same at a ticket of about £12: below that SumUp's flat rate is cheaper, above it myPOS is. Which cards your customers carry matters as much as the ticket — a business taking many corporate or Amex cards pays far more on myPOS.
SumUp suits cafés, market traders and anyone with small average tickets or a card mix heavy in Amex and corporate cards, and businesses that want takings paid free into the bank account they already run.
myPOS suits trades, services and shops with larger tickets paid on ordinary UK consumer cards, and owners who want every payment available to spend within seconds and will treat the myPOS account as their working account.
Two numbers decide it: your average ticket and the share of cards that are not ordinary UK consumer cards. On a domestic consumer card myPOS's 1.10% + 7p beats SumUp's 1.69% on any sale above about £12, and its 1.30% + 15p beats SumUp's 2.5% online above about £12.50 — a tradesperson taking £300 jobs pays £3.37 on myPOS and £5.07 on SumUp. But myPOS charges 2.20% to 2.85% plus 7p on EEA, Amex and business cards, where SumUp's flat 1.69% does not move, so a shop in a tourist area or a B2B supplier can end up paying more on myPOS despite the lower headline. Then the money: myPOS makes every payment spendable within seconds but keeps it in its own e-money account and charges £1.50 each time you move it to your bank; SumUp pays out free to any UK bank in one to two business days, or by 7am the next day into its own account. Both are contract-free with no monthly fee, and both score 4.2 on Trustpilot. Payment Review grades SumUp a B+ and myPOS a B; the site's own edge to SumUp reflects the wider product and the free route to your own bank rather than the transaction price.
| Feature | SumUp | myPOS |
|---|---|---|
| In person — domestic consumer card | 1.69% | 1.10% + 7p Winner |
| On a £10 sale SumUp costs 16.9p and myPOS 18p; on £50, 84.5p against 62p. The two are equal at a ticket of about £11.86, so myPOS is cheaper on almost any sale above £12. | ||
| In person — American Express | 1.69% Winner | 2.45% + 7p |
| In person — EEA consumer card | 1.69% Winner | 2.20% + 7p |
| In person — business, commercial and non-EEA cards | 1.69% Winner | 2.85% + 7p |
| This is the row that catches B2B traders and tourist-area shops: a £100 corporate card costs £1.69 on SumUp and £2.92 on myPOS. | ||
| Online and payment links — domestic consumer card | 2.5% | 1.30% + 15p Winner |
| Crossover at £12.50. myPOS charges 2.50% + 15p for Amex online and 2.90% + 15p for other cards; MOTO is the online rate plus 0.5%. SumUp's 2.5% covers all cards online. | ||
| Optional monthly plan | Payments Plus £19 a month: 0.99% on domestic debit and credit cards in person, 1.69% on premium and Amex, 2.5% online | None — pay-as-you-go only |
| Payments Plus costs £189 a year paid annually, has a 7-day trial and can be cancelled any time. Whether it beats myPOS on domestic consumer cards depends on how many sales you take, since the £19 is recovered from 0.11% of turnover plus 7p a sale: roughly 210 sales of £20 a month (about £4,200 of card turnover) is the break-even. | ||
| Custom pricing threshold | £10,000+ a month | £10,000+ a month |
Recommendations based on your business type
Below about £12 SumUp's 1.69% flat rate is cheaper than myPOS's 1.10% + 7p on every sale, the Solo Lite is the cheapest reader of the pair, and takings arrive by 7am next day into the Business Account or free into your own bank.

On a £150 job myPOS costs £1.72 and SumUp £2.54, the money is spendable from the myPOS card within seconds of the customer tapping, and a Go 2 or Flex is a self-contained 4G device that needs no phone.
myPOS charges 2.20% + 7p on EEA cards, 2.45% + 7p on Amex and 2.85% + 7p on business and non-EEA cards; SumUp charges 1.69% on all of them, and the difference on a card mix like this outweighs myPOS's advantage on domestic consumer cards.
SumUp pays out to any UK bank account at no charge. myPOS settles only into its own e-money account and charges £1.50 for each transfer out, which adds up for a business that sweeps daily.

myPOS's 1.30% + 15p online rate is well under SumUp's 2.5% at that order size — 54p against 75p on £30, and the gap widens with the ticket.
SumUp sells a £249 dual-screen Register and a £39-a-month POS Plus tier; myPOS's range tops out at the Ultra handheld and has no countertop equivalent.
