How to Use a POS System in a Restaurant

‍

In today’s fast-paced dining industry, knowing how to use a POS system in a restaurant can make the difference between a streamlined operation and a chaotic kitchen. A POS (Point-of-Sale) system is more than just a cash register—it’s the central hub for managing orders, inventory, payments, and even customer relationships.

This guide breaks down the basics and best practices for using a restaurant POS system, whether you're setting it up for the first time or training new staff.

What is a Restaurant POS System?

A POS system for restaurants is a digital platform that allows staff to take orders, send them to the kitchen, accept payments, and track business data in real time. Most modern POS systems are cloud-based and accessible from tablets or terminals across the restaurant.

Key Functions of a Restaurant POS System:

• Order taking and table management
• Kitchen display integration
• Payment processing (card, mobile, cash, etc.)
• Inventory and ingredient tracking
• Staff scheduling and time clock
• Reporting and sales analytics

Step-by-Step: How to Use a POS System in a Restaurant

1. Login and Set Up User Profiles

Each employee should have a unique login for tracking orders and sales. Most systems allow permissions to be customized (e.g., servers vs. managers).

2. Set Up Tables and Floor Plan

Use the POS interface to create a digital layout of your restaurant, including table numbers and zones. This helps servers assign and manage orders more easily.

3. Input Menu Items

Upload your full menu into the POS, including:

• Item names and descriptions
• Prices and taxes
• Modifiers (e.g., “no onions,” “extra cheese”)
• Combos or set meals

4. Take and Send Orders

When customers place an order:

• The server taps the items on their device
• The order is automatically sent to the kitchen printer or kitchen display system (KDS)
• Tickets are printed in relevant stations (e.g., bar, grill, prep)

5. Process Payments

POS systems typically support:

• Credit/debit card payments
• Mobile wallets (Apple Pay, Google Pay)
• Cash
• Split bills or multiple payments
  Receipts can be printed or sent via email/text.

How to Train Staff to Use a POS System

• Create practice accounts to let new hires run through mock orders
• Use video or on-screen tutorials that match your POS vendor’s layout
• Simulate common scenarios like voiding an item, splitting a check, or applying a discount
• Have a manager on-site during peak hours to assist with troubleshooting
