Choosing a restaurant POS in 2026 is not only about payments. You are buying front-of-house speed, kitchen routing, reporting, and — increasingly — how honestly a vendor describes what is actually included vs add-on. This comparison covers Toast, Square, and OS Kitchen for US/CA operators evaluating their next stack.
How we compared these platforms
We scored each system on criteria operators report as decision drivers:
- Day-of-service POS (counter, handheld, tabs)
- Kitchen display and ticket routing
- Table management and QR ordering
- Back-of-house production and costing depth
- Total cost including hardware and contracts
- Trial and migration friction
Toast — best when you want established US restaurant hardware
Toast is strong for full-service restaurants that want proprietary terminals, deep US restaurant integrations, and a large partner ecosystem. Hardware bundles and processing relationships are common — read the full contract, not only the monthly software line item.
Strengths: Mature dining room workflows, widespread US support, extensive add-on marketplace.
Tradeoffs: Hardware cost, multi-year agreements on some deals, less flexibility if you want web-only POS on existing tablets.
Square — best for simple counter-first operations
Square is ubiquitous for quick service, retail crossover, and teams that want polished hardware out of the box. Restaurant depth exists but kitchen operations and multi-brand management are thinner than specialized platforms.
Strengths: Fast setup, familiar hardware, strong payments brand.
Tradeoffs: QR and advanced kitchen workflows may require add-ons; production planning for meal prep or ghost kitchens is not the core story.
OS Kitchen — best when POS and kitchen ops must be one web workspace
OS Kitchen targets operators who want browser-based POS, kitchen display, table management, and production tools without mandatory terminal purchases. Strong fit for meal prep, ghost kitchens, and restaurants modernizing without a hardware lease.
Strengths: No proprietary hardware requirement, production board, multi-brand command center, honest integration maturity labels, 14-day trial without credit card.
Tradeoffs: Not a drop-in replacement for every Toast hardware deployment; marketplace integrations require partner access like any platform.

Pricing: compare total cost of ownership
Toast and Square often advertise $0 or low software with hardware and processing bundles. OS Kitchen publishes software from $29/mo with a 14-day trial — you supply tablets. Model five-year TCO including terminals, swaps, and chargeback support before you decide.
Which should you choose?
