A point-of-sale system does far more than process credit cards. Modern POS platforms manage inventory, track employee hours, generate sales reports, handle customer loyalty programs, and sync with your accounting software. The wrong choice means clunky hardware, hidden fees, and locked-in contracts that cost more to escape than to endure. We evaluated five POS systems that serve small businesses across retail, food service, and service industries - focusing on the total cost of ownership, not just the sticker price.

1. Square
Square Best Free Option
Square eliminated the biggest barrier to accepting card payments: cost. The basic POS software is free, the card reader is free, and you pay only a flat processing rate per transaction. No monthly fees, no long-term contracts, no hidden charges. Square has expanded well beyond simple card processing into a full business platform with inventory management, employee scheduling, payroll, online ordering, and customer relationship tools. For small businesses that want to start accepting payments immediately without upfront investment, Square is the obvious first choice.
- Key strength: Free POS software and card reader - pay only per-transaction processing fees
- Processing: 2.6% + $0.10 for in-person; 2.9% + $0.30 for online; 3.5% + $0.15 for manually keyed
- Ecosystem: Square Payroll, Square Loans, Square Online, Square Appointments, and Square Marketing
- Hardware: Free magstripe reader; Square Reader for contactless at $49; Square Terminal at $299; Square Register at $799
2. Toast
Toast Best for Restaurants
Toast was built from the ground up for restaurants, and it shows. The kitchen display system, tableside ordering, menu management, and tip handling are all designed for food service operations. Toast hardware runs on a custom Android-based operating system that handles the grease, heat, and chaos of a real kitchen. The platform includes online ordering, delivery management, payroll, and team scheduling. If you run a restaurant, cafe, bar, or food truck, Toast understands your workflow in a way that general-purpose POS systems simply do not.
- Key strength: Purpose-built for restaurants - kitchen displays, tableside ordering, and menu management
- Hardware: Spill-proof, restaurant-grade terminals designed for kitchen environments
- Features: Online ordering, delivery dispatch, tip management, and employee scheduling included
- Pricing: Starter Kit at $0/mo (higher processing fees); Essentials at $69/mo per terminal; custom Enterprise pricing
3. Lightspeed
Lightspeed Best for Retail
Lightspeed provides the deepest inventory management of any POS system on the market. If you sell products with variants - sizes, colors, materials - Lightspeed tracks every combination across multiple locations without breaking a sweat. The built-in purchase ordering system automates restock based on sales velocity and minimum quantity thresholds. Lightspeed also includes a full e-commerce platform, so your online and in-store inventory stays synchronized automatically. For retailers managing complex product catalogs, Lightspeed removes the spreadsheet-based inventory tracking that other systems force you into.
- Key strength: Advanced inventory management with multi-location tracking, variants, and automated purchasing
- Reporting: Built-in analytics covering sell-through rates, margin analysis, and employee performance
- E-commerce: Integrated online store with unified inventory - sell online and in-store from one system
- Pricing: Basic at $89/mo; Core at $149/mo; Plus at $239/mo (annual billing)
4. Clover
Clover Best Hardware
Clover makes the best-looking POS hardware in the industry. The countertop Station Duo features a customer-facing display that shows order totals and accepts contactless payments, while the merchant display runs the full POS software. Beyond aesthetics, Clover hardware is fast and reliable. The Clover App Market lets you add functionality - loyalty programs, table management, appointment booking - without switching platforms. Clover is sold through payment processing partners, which means pricing and contract terms vary by reseller. Always compare offers from multiple Clover resellers before signing.
- Key strength: Premium hardware design with customer-facing displays and fast, reliable performance
- App Market: Hundreds of apps for loyalty, marketing, accounting integration, and industry-specific features
- Flexibility: Available for retail, restaurants, services, and mobile businesses with tailored software for each
- Hardware: Clover Go at $49; Clover Flex at $599; Clover Mini at $799; Clover Station Duo at $1,799
5. Shopify POS
Shopify POS Best Omnichannel
Shopify POS bridges the gap between online and in-person selling better than any other system. If you already sell through Shopify online, the POS extension turns your phone or tablet into a point-of-sale terminal that shares the same product catalog, customer database, and inventory counts. Customers can buy online and pick up in store, return in-store purchases by mail, or browse in-store and have items shipped to their home. The unified customer profile tracks every interaction across channels. For businesses that sell both online and in person, Shopify POS eliminates the data silos that plague multi-channel operations.
- Key strength: Seamless omnichannel - unified inventory, customers, and orders across online and in-store
- Features: Buy online pick up in store, in-store returns for online orders, and unified customer profiles
- Integration: Connects to the full Shopify ecosystem of 8,000+ apps and all online sales channels
- Pricing: POS Lite included free with Shopify plans; POS Pro at $89/mo per location (adds staff management and advanced inventory)

How to Choose
New businesses on a budget should start with Square. Zero monthly fees, no contracts, and free hardware mean you can start accepting payments today with no financial risk. You can upgrade hardware and add features as you grow.
Restaurants, cafes, and food trucks should go with Toast. The restaurant-specific features - kitchen displays, tableside ordering, tip management - save hours of workarounds that general POS systems require. The starter kit at $0/mo removes the upfront barrier.
Retail businesses with complex inventory need Lightspeed. If you manage hundreds of SKUs with variants, multiple suppliers, and reorder points, Lightspeed's inventory system pays for itself in time saved and stockouts avoided.
Businesses that want premium hardware should look at Clover. The customer-facing displays and build quality make a professional impression. Just compare offers from multiple resellers before committing.
Omnichannel sellers already using Shopify should add Shopify POS. The unified inventory and customer data across online and physical stores creates a seamless experience that separate systems cannot match.
Final Verdict
Square is the best starting point for most small businesses. Free software, transparent pricing, and no contracts let you focus on selling rather than managing your POS vendor. Toast is the clear winner for any food service operation. Lightspeed earns its higher price through inventory management that serious retailers need. Clover delivers the best hardware experience if you are willing to shop around for processing rates. And Shopify POS is unbeatable for businesses that sell online and in person through a single unified system.
