POS Systems Comparison: Types, Features, and How to Choose the Right One

A comprehensive comparison of POS system types, features, and pricing to help you choose the right point of sale for your business.

Types of POS Systems

Point of sale systems come in several categories, each designed for different business types and operational needs. Choosing the right type is the most important decision — features, pricing, and capabilities vary significantly.

Cloud-Based POS Systems

Cloud POS systems store data online and run on standard hardware (tablets, smartphones, computers). They are the most popular POS type for small to medium businesses.

Pros: Low upfront cost, automatic updates, access data from anywhere, easy setup Cons: Requires internet connection, recurring subscription fees (with some providers) Best for: Retail, cafes, quick-service restaurants, service businesses Examples: Clover POS, Square POS, Toast POS, Lightspeed

Traditional/Legacy POS Systems

On-premise systems with proprietary hardware and software. Data is stored locally on the terminal.

Pros: Works without internet, high reliability, established support Cons: Expensive hardware, manual updates, limited remote access Best for: Large restaurants, hotels, enterprise retail Examples: Aloha POS, Micros/Oracle, NCR

Mobile POS (mPOS)

Smartphone or tablet-based systems with portable card readers. Process payments anywhere.

Pros: Portable, low cost, great for mobile businesses Cons: Limited features compared to full POS, smaller screen Best for: Food trucks, pop-ups, farmers markets, field service Examples: Clover Go, Square Reader, PayPal Zettle

Self-Service Kiosks

Customer-facing terminals where customers place orders and pay without staff interaction.

Pros: Reduce labor costs, increase order accuracy, higher average tickets Cons: Higher hardware cost, not suited for all business types Best for: Fast food, cafeterias, movie theaters, parking Examples: Custom kiosk solutions, Clover Kiosk

POS Systems by Business Type

Restaurant POS Systems

Restaurants need POS systems with table management, kitchen display integration, tip handling, and menu modifier support. The right restaurant POS depends on service type:

Retail POS Systems

Retail POS systems prioritize inventory management, barcode scanning, and customer management. Key features include:

  • Product catalog with variants (size, color)
  • Barcode/SKU scanning
  • Inventory tracking and low-stock alerts
  • Customer profiles and purchase history
  • Returns and exchanges
  • Gift card management

Top retail POS options: Clover Station, Korona POS, Lightspeed Retail

Service Business POS

Service businesses (salons, auto repair, contractors) need appointment integration, customer management, and mobile processing.

Options: Clover Flex for mobile, Clover Station for counter service

Major POS System Providers Compared

Key insight: POS systems through Unison Payment Solutions use interchange-plus pricing with zero monthly fees. This typically saves 20-30% compared to flat-rate POS providers like Square and Toast, especially for businesses with significant debit card volume.

How to Choose the Right POS System

1. Identify your business type — restaurant, retail, service, or multi-function. This narrows options immediately. 2. List must-have features — inventory? Table management? Online ordering? Loyalty? Make a requirements list. 3. Consider processing costs — interchange-plus pricing saves significantly over flat-rate. Calculate your actual savings with a rate comparison. 4. Evaluate hardware needs — how many terminals? Mobile? Countertop? Kitchen display? Factor hardware costs. 5. Check contract terms — avoid long-term contracts and early termination fees. Unison offers month-to-month with no contracts. 6. Request a democontact us to see POS options configured for your business type.

Getting the Best POS Deal

Most POS providers bundle hardware and processing together at flat rates that overcharge on processing to subsidize "free" hardware. The total cost of ownership over 2-3 years is almost always higher than buying hardware outright and using interchange-plus processing.

Unison Payment Solutions provides POS hardware with interchange-plus processing — no monthly fees, no contracts. Contact us for a total cost comparison against your current POS or any competitor you're evaluating.

Frequently Asked Questions

What are the main types of POS systems?
The main types are cloud-based POS (Clover, Square, Toast), traditional/legacy POS (Aloha, Micros), mobile POS (Clover Go, Square Reader), and self-service kiosks. Cloud-based systems are the most popular for small to medium businesses due to lower cost and easier setup.
What is the best POS system for a small business?
For most small businesses, cloud-based POS systems offer the best value. Clover POS through Unison provides interchange-plus pricing (saving 20-30% vs flat-rate), zero monthly fees, and hardware options from $49 to $1,799 depending on needs. The right model depends on your specific business type.
How much does a POS system cost?
Hardware ranges from $49 (mobile reader) to $1,799+ (full POS station). Processing costs vary by provider: flat-rate processors charge 2.6-2.9% on every transaction, while interchange-plus through Unison saves 20-30% with no monthly fees. Total cost of ownership over 2-3 years matters more than upfront hardware price.
What is the difference between cloud POS and traditional POS?
Cloud POS stores data online, runs on standard hardware, updates automatically, and can be accessed from anywhere. Traditional POS uses proprietary hardware, stores data locally, and requires manual updates. Cloud POS is generally better for small/medium businesses; traditional POS suits large operations with established infrastructure.
Which POS system has the lowest processing fees?
POS systems using interchange-plus pricing (like Clover and PAX through Unison) have the lowest processing fees. Flat-rate systems (Square at 2.6%+10¢, Toast at 2.49%+15¢) charge the same rate regardless of card type, overcharging significantly on debit card transactions. Interchange-plus passes the actual wholesale rate through to you.
