What is a POS system? Restaurant point of sale explained

The system where transactions are completed, combining hardware and software for order processing and payment.

A POS (Point of Sale) system is the hardware and software combination restaurants use to process orders, manage payments, and track sales. For restaurants, the POS is the central nervous system that handles everything from taking orders to generating reports. A modern POS processes hundreds of transactions daily while capturing data that drives business decisions.

The quick definition

POS stands for Point of Sale. It refers to the complete system where restaurant transactions happen, including both the physical hardware (terminals, tablets, card readers) and the software that manages orders, payments, and data.

Order entry	Servers input food and drink orders
Kitchen communication	Orders sent to kitchen displays or printers
Payment processing	Cash, credit, debit, mobile payments
Check management	Split checks, transfers, modifications
Reporting	Sales, labor, and inventory analytics

Why POS matters

Operational efficiency

A good POS streamlines every transaction:

Orders flow directly to kitchen
Payments process in seconds
Checks split with one click
Modifiers and allergies tracked automatically

Data and insights

POS data reveals business patterns:

Data Type	Business Value
Sales by hour	Staffing optimization
Item popularity	Menu engineering
Server performance	Training needs
Payment mix	Cash handling requirements

Financial control

POS systems provide accountability:

Track every transaction
Monitor voids and comps
Calculate cash drawer variances
Generate accurate tax reporting

Types of restaurant POS systems

Traditional (legacy) POS

Installed locally on dedicated hardware:

Characteristic	Detail
Upfront cost	$3,000-15,000
Ownership	Restaurant owns hardware
Data storage	On-site server
Updates	Manual, often paid
Support	On-site IT often needed

Examples: Aloha, MICROS

Cloud-based POS

Software runs in the cloud, accessed via tablets or terminals:

Characteristic	Detail
Upfront cost	$500-2,000 (hardware only)
Monthly cost	$50-300
Data storage	Cloud servers
Updates	Automatic, included
Support	Remote, 24/7 available

Examples: Toast, Square, TouchBistro, Lightspeed

Hybrid systems

Combine cloud benefits with local redundancy:

Data syncs to cloud for access anywhere
Works offline if internet drops
Local backup prevents data loss
Best of both approaches

Key POS components

Hardware

Terminal or tablet	Main interface for order entry
Card reader	Process credit and debit payments
Cash drawer	Secure cash storage
Receipt printer	Guest receipts
Kitchen printer or KDS	Orders to kitchen
Barcode scanner	Inventory and retail items

How to calculate POS costs

Monthly cost breakdown

Cost Category	Range
Software subscription	$50-300/month
Payment processing	2.0-3.0% + $0.10-0.30 per transaction
Hardware (amortized)	$50-150/month
Support add-ons	$0-100/month

Processing fee example

On $50,000 monthly card sales at 2.5% + $0.10:

Percentage fee: $1,250
Per-transaction fee (1,000 transactions): $100
Total monthly processing: $1,350

Total cost of ownership

Calculate your true costs:

First Year	Cloud-Based	Traditional
Hardware	$1,500	$5,000
Software	$2,400	$1,000
Installation	$0	$500
Total Year 1	$3,900	$6,500

Cloud-based often costs less long-term due to lower upfront investment.

POS and reservation system integration

Why integration matters

When POS and reservation systems communicate:

Benefit	Description
Guest history	Reservation data appears in POS
Spending data	Purchase history flows to reservation profiles
VIP recognition	Status visible to servers
Marketing	Visit details enable targeted outreach

Common integrations

Most reservation systems integrate with major POS platforms:

Toast
Square
Lightspeed
TouchBistro
Clover
Revel

Check integration capabilities when choosing both systems.

How to choose a restaurant POS

Key considerations

Factor	Questions to Ask
Ease of use	How quickly can staff learn it?
Reliability	What is the uptime guarantee?
Cost structure	What are all the fees?
Features	Does it include what you need?
Integrations	Does it connect with your other systems?
Support	What happens when something breaks?

Questions for vendors

What is the total monthly cost including processing fees?
Do you integrate with my reservation system?
What happens if internet goes down?
What is your uptime history?
How long does staff training take?
What is the contract term?
How do you handle menu changes?

Common POS mistakes

Choosing on price alone

The cheapest POS may lack features you need or have higher processing fees.

Ignoring integration needs

A POS that does not connect with your other systems creates data silos.

Underestimating training

New POS systems require staff training. Plan for the transition period.

Not reviewing reports

POS data is valuable only if you use it. Schedule regular report reviews.

Skipping security

PCI compliance and data security matter. Verify your POS meets standards.
