Kotao vs SumUp.

SumUp started in Berlin in 2012 with a simple promise: a €39 card reader, sign up in minutes, take cards by lunchtime. More than a decade later, it's still the European go-to for solo merchants, food trucks, market stalls, hair salons, freelancers, and pop-ups. The hardware lineup — Air, Solo, 3G — is dirt cheap, globally available, and works the moment you unbox it.

SumUp is honest about what it is. It's a starter tool for the smallest end of the market, and it integrates cleanly with European accounting tools like Lexware and sevDesk. They don't oversell themselves as a platform competitor — they sell card acceptance, a till app, and a basic online store, and they sell those things very well to people who need to take a payment tomorrow morning.

One platform, not just POS plus payments. SumUp ships a card reader, a till app, and a basic online store. That's the scope. Kotao puts POS, PMS, CRM, ERP, payments, and storefront behind one customer record. The moment you outgrow a single till — when you add staff, a second location, a hotel arm, or real online ordering — SumUp leaves you stitching together third-party tools.

Built for groups, not single merchants. SumUp is single-merchant-shaped at its core: one operator, one terminal, one bank account. Kotao is built for multi-location and multi-property operators from day one — a hotel with a restaurant, a café group across cities, a retail chain with shared inventory and one customer record across every surface.

First-class storefront, not a bolt-on. SumUp Online Store covers the basics for a market-stall operator who wants a few products online. It does not compete with Shopify-class commerce. Kotao ships a real storefront with shared inventory, shared customers, and unified pricing across in-store, online, and hospitality channels.

Unified customer record across every surface. SumUp tracks transactions per channel; data lives in silos. Kotao surfaces the same customer in the POS, the online store, the hotel reservation, and the restaurant table — one record, one history, every interaction visible to the operator.

Lowest barrier to entry on the market. SumUp is unbeatable for solo operators who need to take a single card payment tomorrow. €39 reader, sign up in minutes, no monthly fee on the till app. No platform we know of makes the first-payment journey shorter or cheaper.

Dirt-cheap, globally available hardware. The SumUp Air, Solo, and 3G readers are inexpensive, well-stocked, and shipped across most of Europe and beyond. Kotao's hardware kit is broader and more opinionated, tuned for hospitality and retail at scale rather than the cheapest possible reader.

Honest scope and clean accounting integrations. SumUp doesn't oversell itself as a platform — it integrates well with Lexware, sevDesk, and other European accounting tools, and operators know exactly what they're getting. For a freelancer or pop-up that wants payments and accounting and nothing more, that focus is a real strength.

Brand recognition with sole proprietors. Across European markets, food truck and pop-up operators recognize the SumUp Air on sight. That trust and ubiquity matter when a customer is deciding whether to tap their card at a market stall.

Comparable entry-level card economics. SumUp's in-person card pricing is competitive for very small merchants. On payments-only reasons, this is not the strongest reason to switch; the real gap is the operating platform around the payment.

Pick SumUp if: you're a solo merchant, food truck, market stall, hairdresser, freelancer, or pop-up operator; you need the absolute lowest barrier to entry; you want a €39 reader and a card payment tomorrow morning; or your business genuinely fits inside POS plus payments plus a basic online store with European accounting integrations on the side.

Pick Kotao if: you've outgrown SumUp's tooling — multiple staff, multiple locations, a hotel-and-restaurant combination, a real CRM, or unified inventory across in-store and online; you want one customer record across every surface; or you operate at a scale where SumUp's single-merchant shape starts to limit you.
