KDS (Kitchen Display System)
What a KDS is
A Kitchen Display System (KDS) is a screen mounted in the kitchen that receives orders from the point-of-sale terminal and displays them for kitchen staff to prepare. It replaces the paper ticket (KOT) and the verbal relay from front-of-house to back-of-house.
Modern KDS systems:
- Colour-code orders by ticket age (green = new, yellow = in progress, red = running late)
- Route items to the correct station (grill, saute, cold prep, expo)
- Course-manage items (fire desserts only when mains are nearly complete)
- Track prep time per ticket, enabling kitchen performance reporting
KDS in the POS market
Not every POS includes a KDS. Square includes a basic KDS in Square for Restaurants (free and paid tiers). Toast’s KDS is the benchmark in the sub-enterprise category — it handles complex routing, expo-station views, and pay-at-table integration in a way Square’s does not.
Practical comparison at a 150-cover restaurant:
- Toast KDS with expo station view: routes 8-course menus to 4 stations, alerts expo when courses are ready to fire, integrates with Toast Go handheld for instant order capture. Cost: included in Toast’s restaurant plans.
- Square KDS: handles basic item display per station, simpler course management. Functional for QSR and fast-casual, thin for full-service fine dining.
When a KDS matters enough to affect your POS choice
If your kitchen handles more than 80 covers/service or has more than 2 prep stations, the KDS quality will materially affect your throughput and ticket times. At this scale, Toast’s KDS advantage is real and worth the contract premium — for operators who can commit to the 2-year term.
Below 80 covers/service, Square’s KDS is adequate and the processing-rate saving (1.75% vs 2.49%) more than offsets the workflow limitation.
