Choosing restaurant POS software in 2026 is less about counting features on a demo slide and more about whether your floor, kitchen, and back office share one ticket stream. This guide helps operators compare Toast, Square, legacy terminals, and operations-first platforms like OS Kitchen.
1. Start with service model, not vendor logos
Counter-only cafés need fast checkout and simple modifiers. Full-service restaurants need table states, coursing, and split checks. Meal prep and ghost kitchens need production boards and route planning more than floor plans. Write down your top three daily workflows before you watch demos.
2. Model five-year total cost of ownership
Include terminals, swaps, chargebacks, add-on KDS apps, and implementation time. A lower monthly software fee can lose to hardware leases and per-location app fees.
3. Require a live kitchen test
Run a Friday-night simulation: 30 concurrent tickets, modifier changes, voids, and a storefront order landing in the same KDS. Latency above 200ms on order list queries is a red flag for busy service.
