A modern POS system does far more than ring up sales. It tracks inventory in real time, manages employee schedules and permissions, builds customer profiles for loyalty programs, and generates the sales analytics you need to make purchasing decisions. The best systems in 2026 also connect your in-store and online sales into a single view. Your POS feeds directly into your accounting software and syncs with your e-commerce platform for unified commerce.

We evaluated seven POS systems across three dimensions: total cost of ownership (software, hardware, and processing fees combined), how well the system handles day-to-day operations beyond payment processing, and whether it scales from one location to multiple without a platform migration.
1. Square POS
Square Best Free Start
Square's free POS software and $49 card reader make it the lowest-barrier entry point for any small business. The app runs on any iPad or Android tablet, and the core features - payment processing, basic inventory, digital receipts, and sales reports - cost nothing beyond the per-transaction fee. Square's ecosystem extends into online sales (Square Online), invoicing, payroll, and banking, so you can grow without switching platforms. The 2026 update adds AI-powered sales forecasting and automated inventory reordering.
- Pricing: Free (basic POS); Plus $29/mo/location (retail); Premium $79/mo; Processing 2.6% + $0.10
- Pros: Free core POS, $49 hardware start, full ecosystem, next-day deposits, no long-term contracts, AI forecasting
- Cons: Processing fees not negotiable on free plan, account stability issues reported, limited offline mode
- Best for: New businesses, pop-up shops, and solopreneurs that want to start selling with minimal investment
2. Shopify POS
Shopify POS Best Omnichannel
Shopify POS unifies online and in-store sales under one inventory and customer database. Buy online, pick up in store (BOPIS), ship from store, and return anywhere all work natively. The product catalog, pricing, and stock levels stay synchronized across your Shopify website, retail locations, and social commerce channels without manual reconciliation. For businesses that sell both online and offline, this eliminates the inventory split that causes overselling.
- Pricing: POS Lite included with Shopify ($39/mo); POS Pro $89/mo/location; Processing 2.4%-2.7%
- Pros: True omnichannel, unified inventory, BOPIS, ship-from-store, Shopify ecosystem, staff management
- Cons: Requires Shopify subscription, POS Pro expensive per location, hardware costs add up
- Best for: Retailers that sell both online and in-store and need a single unified inventory and customer view
3. Toast
Toast Best Restaurant
Toast is purpose-built for restaurants and food service. The kitchen display system replaces paper tickets, online ordering feeds directly into the POS, and tableside ordering with handheld devices increases table turnover by 10-15%. Menu management handles modifiers, courses, and dietary labels natively. The 2026 AI update analyzes sales patterns to recommend menu pricing, predict busy periods for staffing, and identify underperforming menu items.
- Pricing: Starter free (pay-as-you-go, higher processing); Essentials $69/mo; Growth $165/mo; Processing 2.49%-3.09% + $0.15
- Pros: Restaurant-specific, kitchen display, online ordering, tableside handhelds, AI menu analytics, payroll integration
- Cons: Restaurant-only, 2-year hardware contracts, higher processing on free plan, hardware proprietary
- Best for: Full-service and quick-service restaurants that need an all-in-one restaurant management platform
Tip: Calculate total cost, not just software fees
A "free" POS with 2.9% processing costs more than a $79/month POS with 2.4% processing once you exceed roughly $15,000 in monthly card sales. Calculate your total cost: (monthly volume x processing rate) + software fee + hardware amortization. Track your payment data in your BI platform to optimize processing costs over time.
4. Clover
Clover Best Hardware
Clover's proprietary hardware is the most polished in the POS market. The countertop station, handheld Flex, and compact Mini all run Clover's Android-based OS with a responsive touch interface. The app marketplace adds functionality for specific industries - appointments for salons, table management for restaurants, age verification for liquor stores. Clover's processing rates are negotiable through Fiserv (its parent company), which can significantly reduce costs for high-volume businesses.
- Pricing: Starter $14.95/mo; Standard $49.95/mo; Advanced $69.90/mo; Hardware $49-$1,799; Processing 2.3%-2.6% + $0.10
- Pros: Best hardware design, app marketplace, negotiable rates, multiple form factors, offline mode, multi-location
- Cons: Hardware locked to Clover, reseller pricing varies wildly, some resellers add hidden fees, app quality uneven
- Best for: Retail and service businesses that value premium hardware and want customization through an app marketplace
5. Lightspeed Retail
Lightspeed Best Inventory
Lightspeed has the deepest inventory management of any POS system. Matrix inventory handles products with multiple variants (size, color, material) without creating separate SKUs. Built-in purchase ordering with vendor catalogs lets you reorder stock directly from the POS. The analytics module tracks inventory turnover, sell-through rates, and gross margin by product, category, and vendor. For retailers with complex product catalogs, Lightspeed eliminates the need for a separate inventory system.
- Pricing: Basic $89/mo; Core $149/mo; Plus $289/mo; Processing 2.6% + $0.10
- Pros: Deep inventory (matrix, variants, bundles), built-in purchase orders, vendor catalogs, advanced analytics, e-commerce
- Cons: Higher starting price, complex for simple retail, requires annual contract for best rates, learning curve
- Best for: Specialty retailers with large or complex product catalogs that need advanced inventory and analytics
6. PayPal Zettle
PayPal Zettle Best Mobile
PayPal Zettle (formerly iZettle) offers the simplest mobile POS for businesses that sell on the go. The $29 card reader connects to any smartphone via Bluetooth, and the app handles sales, basic inventory, and reporting. PayPal integration means funds can go directly to your PayPal balance for instant access. For market vendors, food trucks, and service providers that sell face-to-face without a permanent location, Zettle's portability and price point are unbeatable.
- Pricing: Free software; Card reader $29 (first one free with promo); Processing 2.29% + $0.09
- Pros: Lowest processing rate, $29 reader, PayPal integration, instant access to funds, no monthly fees, simple setup
- Cons: Basic inventory, limited reporting, no kitchen display, no advanced features, phone-dependent
- Best for: Mobile sellers, market vendors, and service providers that need portable card acceptance
7. Revel Systems
Revel Best Multi-Location
Revel is built for businesses scaling beyond one or two locations. The multi-location management console provides a single view of sales, inventory, and labor across all stores. Role-based permissions control what each employee can access at each location. The open API and integration marketplace connect Revel to enterprise tools like Oracle, SAP, and custom applications. For franchise operations, Revel's centralized control with per-location customization is a key differentiator.
- Pricing: Starting $99/mo/terminal (3-year contract); Processing negotiable; Implementation fee applies
- Pros: True multi-location, open API, franchise management, iPad-based, robust offline mode, enterprise integrations
- Cons: 3-year contract required, implementation fees, higher total cost, iPad hardware required, complex setup
- Best for: Multi-location retailers and franchise operators that need centralized control with local flexibility

Frequently Asked Questions
What is the cheapest POS system for small business?
Square POS is the cheapest to start with - the software is free and the card reader costs $49. You pay only processing fees of 2.6% + $0.10 per transaction. For businesses processing over $10,000 monthly, Toast (restaurants) or Clover offer competitive processing rates that can offset their monthly software fees.
Do I need a POS system or can I use a payment terminal?
A payment terminal only processes transactions. A POS system adds inventory tracking, sales reporting, customer management, employee permissions, and integrations with accounting and e-commerce. If you sell more than a handful of products or want any business analytics, a POS system pays for itself through better inventory control and operational insights.
What are the total costs of a POS system?
Total POS costs include hardware ($49-$1,500), monthly software ($0-$165/month), and payment processing fees (2.4%-2.9% + $0.10-$0.30 per transaction). A typical small retailer spends $50-$150 per month total. The processing fee is usually the largest cost - on $20,000 monthly sales, processing at 2.6% costs $520/month regardless of hardware or software fees.
