If you're researching card readers and point-of-sale, SumUp shows up on every shortlist. This guide covers what SumUp actually is, who it's built for, how it stacks up against the alternatives, and the questions worth asking before you commit.
The short version: SumUp is a card-reader and POS platform built for small merchants — no monthly fee, per-transaction pricing instead. It fits market traders, cafés, tradespeople and small shops that don't want a fixed monthly bill just to accept cards. Worth cross-checking against Zettle by PayPal, Square and myPOS before you decide.
What SumUp actually is
01What's under the hood
- Card readers from £39 with tap/insert/swipe. This is central to what SumUp offers, and the entry point most people start from.
- No monthly fee, per-transaction 1.69–2.5%. A differentiator against typical card readers and point-of-sale competitors that charge a fixed monthly platform fee.
- Free e-commerce and invoicing tools. Worth understanding — it extends SumUp past the physical counter.
- Next-day payouts standard. Worth understanding — it affects day-to-day cash flow for a small business.
- Integrated POS Lite terminal for shops. Worth understanding — it's the step up from a standalone reader once you need a till-style setup.
Who SumUp fits
Best fit
Small merchants who value card readers from £39 with tap/insert/swipe; market traders and cafés who want no monthly fee, per-transaction 1.69–2.5% pricing instead; people switching from Zettle by PayPal who want free e-commerce and invoicing tools bundled in.
Not ideal
Users needing very-niche vertical features SumUp doesn't cover; enterprise buyers who need a formal SLA and procurement flow; budget shoppers below the entry tier who won't use anything past the free elements.
How it compares
The three names that come up most against SumUp are Zettle by PayPal, Square and myPOS — each with a different trade-off.
| Product | Where it wins | Where it loses |
|---|---|---|
| SumUp | Price-to-capability balance, no monthly fee | Not the most feature-rich at the top end |
| Zettle by PayPal | Most feature-rich, deepest ecosystem | Most expensive; often over-featured for smaller users |
| Square | Feature parity close to SumUp at a similar price | Differences are mostly workflow-specific, not decisive |
| myPOS | A viable option with its own design philosophy | Less of a natural fit once you're comparing SumUp and Zettle by PayPal |
For most small merchants, SumUp hits the sweet spot on price plus capability — current tier options are worth checking before you commit.
