What is a POS system in a restaurant, and how does it work?

The definition

A restaurant POS (point of sale) is the system that records what a guest ordered, sends it to the people who make it, and takes the payment. A modern one does more: it holds the floor plan, the menu, the reservations, the staff permissions and the stock, so the till is only one part of it.

The useful way to think about it is a ticket's journey. Everything a POS does is in service of moving one ticket cleanly from the table to the pass to the bill.

How a ticket moves through service

• Seat — the host assigns the party to a table on the floor plan and records covers
• Order — the server adds items, modifiers and allergy notes against that table's open ticket
• Fire — the ticket is sent to the kitchen display, routed to the right station and course
• Cook and serve — the kitchen moves the ticket from queued to in progress to served, with elapsed time visible
• Bill — the ticket is closed, split if needed, and paid; the table returns to needs-bussing
• Reconcile — sales, voids, comps and stock movements land in the night's reporting

The parts of a restaurant POS

• Floor plan and table management — who is sitting where, and what state each table is in
• Menu and modifiers — items, prices, options and availability per location
• Kitchen display system (KDS) — screens on the line that replace paper chits
• Payments — card, cash, splits by seat or item, tips and refunds
• Reservations and guest records — bookings, no-show history, loyalty
• Inventory — ingredient lots, waste and counts tied to what was sold
• Roles and audit — who can comp, void or refund, and a record of every time they did

Legacy till vs modern POS

A legacy till prints a chit and totals a bill. A modern cloud POS keeps the whole service state — table status, ticket timing, stock movement, staff actions — in one auditable record you can query later. The practical differences show up on a busy Saturday: no lost chits, no duplicate charges when a tablet drops its connection, and an end-of-night report that reconciles instead of being reconstructed.

What to look for when you evaluate one

• Does the kitchen display come included, and can it route by station and course?
• Are duplicate submissions impossible, or does a double tap create two tickets?
• Can a manager-only action like a comp be enforced, and is it logged?
• Does it handle more than one location without a separate account per site?
• Can you export your own data, and what does leaving cost?

Try it on your own menu

TenantVolt's restaurant engine includes the floor plan, KDS, tickets, reservations and ingredient inventory in every plan, starting at $49 per month per location. The fastest way to judge any POS is to build your own menu into it and run one mock service.
