Point of sale (POS)
A point of sale (POS) is the system you use to ring up orders and take payment, and it is the hub where your sales, menu, and guest data are recorded.
The point of sale is the register, but calling it a register undersells it. Modern restaurant POS systems (Toast, Square for Restaurants, Lightspeed Restaurant, TouchBistro, and others) are the operational hub of the business: they take the order, route it to the kitchen, process the payment, and in doing so capture a precise record of what sold, when, at what price, and increasingly to whom. That data exhaust is the single most valuable asset most restaurants own and underuse.
It matters because almost every other system worth having reads from the POS. Demand forecasting needs its sales history. Menu engineering needs its item-level margins. Loyalty, First-party data, and a real Customer data platform (CDP) need its transaction records. Inventory and food-cost tools reconcile against it. Choosing and wiring your POS well is upstream of nearly everything else you can do with technology, which is part of why the category is so large: Toast alone served 156,000 locations / $2.0B ARR as of Q3 2025.
A note for indie operators: MISE is deliberately POS-agnostic. There is no single best POS, only the one that fits your service model, your margins, and the tools you want to connect. What matters more than the brand is that you actually use the data it collects. A POS whose reports you never open is an expensive cash drawer.
