Best POS systems (2026): 7 tools compared

A POS system runs checkout, inventory, staff permissions, and usually payments, so it touches every sale and is painful to replace. Restaurants need handhelds and kitchen displays, specialty retailers need deep variants and purchase orders, and franchise groups need central menu control. Hardware financing, multi-year contracts, and required payment processing often matter more than the software itself. We compared seven systems across those business types.

Seven vendors below with disclosed affiliate or partner programs. Each block: fit, strengths, blocker, pricing.

We compared industry-specific features, hardware options, offline mode, inventory depth, reporting, payment processing rates, and contract terms. We also looked at multi-location management for groups that run more than one store or restaurant.

Square POS · POS systems

Ideal use: Cafes, retail shops, salons, and pop-ups that want free POS software with flat-rate payments and affordable hardware.

What works: Square POS software is free to start, and dedicated modes for retail, restaurants, and appointments fit different businesses. Hardware from a card reader to a full register is simple to set up.

What breaks the deal: Flat-rate processing becomes expensive at high volume, and advanced restaurant or inventory features need paid plans.

Pricing: Entry: $0/mo. Hidden cost: Free software; processing 2.6% + 10¢ in-person. Verify: squareup.com/us/en/point-of-sale/pricing.

Ops note: Run a week of sales on the free plan with a card reader and track your effective processing rate. Test offline mode by disconnecting Wi-Fi mid-sale.

Shopify POS · POS systems

Ideal use: Shopify merchants that sell in stores, markets, or pop-ups and want one inventory and customer database across online and in-person.

What works: Shopify POS shares products, inventory, and customer profiles with your online store, so buy-online-pickup-in-store and returns work across channels. POS Pro adds staff roles and store analytics.

What breaks the deal: Payments outside Shopify Payments incur extra fees, and POS Pro costs per location.

Pricing: Entry: $39/mo. Hidden cost: Basic plan includes POS Lite; Pro POS hardware separate. Verify: shopify.com/pricing.

Ops note: Sell a product in person, then process a return for an online order at the counter. Check inventory updates across both channels.

Toast · POS systems

Ideal use: Full-service and quick-service restaurants that want POS, online ordering, kitchen display, payroll, and handhelds built for restaurants.

What works: Toast is designed specifically for restaurants, with handheld ordering, kitchen display systems, and online ordering without third-party commissions. Payroll, scheduling, and loyalty are built in.

What breaks the deal: Contracts, hardware costs, and processing rates can lock you in, and it runs only on Toast's Android hardware.

Pricing: Entry: Quote. Hidden cost: Restaurant POS software plus payment processing; hardware lease. Verify: pos.toasttab.com/pricing.

Ops note: Run a demo service with handheld ordering, kitchen display, and online orders. Read the contract term and early termination fees carefully.

Lightspeed Retail · POS systems

Ideal use: Specialty retailers such as bike, apparel, and sporting goods stores with deep inventory, variants, and multiple locations.

What works: Lightspeed Retail handles complex variants, serial numbers, purchase orders, and multi-location stock transfers well. Reporting by category, supplier, and staff member suits specialty retailers that manage margins closely.

What breaks the deal: Pricing is higher than Square and payments add-on requirements have tightened.

Pricing: Entry: $89/mo. Hidden cost: Lean per location; payment processing and hardware lease. Verify: lightspeedhq.com/pricing/retail.

Ops note: Import a product line with variants, create a purchase order from a supplier catalog, and transfer stock between locations. Check payments requirements.

Clover · POS systems

Ideal use: Small and mid-size businesses that want sleek POS hardware through their bank or payment provider, with an app market for extras.

What works: Clover's hardware lineup ranges from handheld Flex to full Station registers, and its app market adds loyalty, scheduling, and inventory. It is sold through Fiserv and many banks.

What breaks the deal: Pricing and contract terms vary by reseller, and some reseller agreements include long terms and fees.

Pricing: Entry: $14.95/mo. Hidden cost: Software plus hardware lease; processing rates via Fiserv. Verify: clover.com/pricing.

Ops note: Get quotes from Clover directly and from your bank and compare contract terms. Test the apps you would need.

Vend (Lightspeed) · POS systems

Ideal use: Existing Vend retailers deciding how to handle the move to Lightspeed. Vend has become Lightspeed Retail X-Series.

What works: Vend was known for a clean browser-based POS that ran on iPads, Macs, and PCs with strong offline mode. As Lightspeed X-Series it keeps that interface while adding Lightspeed's payments and supplier tools.

What breaks the deal: The Vend brand is retired, and Lightspeed is steering customers toward its own payments, which changes long-term pricing.

Pricing: Entry: N/A. Hidden cost: Lightspeed Retail acquired Vend; new sales via Lightspeed. Verify: lightspeedhq.com/vend.

Ops note: Check what your plan becomes under X-Series and whether Lightspeed Payments is required. Test offline mode on your existing hardware after the migration.

Revel Systems · POS systems

Ideal use: Multi-location restaurant groups and franchises that want an iPad POS with enterprise reporting, menu control, and open APIs.

What works: Revel runs on iPads with centralized menu management, so a franchise can push price changes to every location at once. Its open API and integrations support loyalty, delivery, and accounting systems.

What breaks the deal: Contracts and setup fees are significant, and the product is heavy for a single small cafe.

Pricing: Entry: Quote. Hidden cost: iPad POS per terminal; payment processing bundled quote. Verify: revelsystems.com/pricing.

Ops note: Push a menu change from headquarters to two test locations and check how fast it appears on each POS. Review contract length and hardware financing terms.

Summary table

Quick verdict

Square POS is the best starting point for small shops, cafes, and salons that want free software and flat-rate pricing. Toast is the strongest choice for full-service and quick-service restaurants that need handhelds, kitchen displays, and commission-free online ordering. Specialty retailers with complex catalogs should look at Lightspeed Retail.

Read the contract length, hardware ownership terms, and early termination fees before you sign, since those decide how easily you can leave. Run a demo shift with offline mode tested, because Wi-Fi drops during a rush are when a POS proves itself.
