Restaurant POS System Comparison: Toast vs Square vs Lightspeed for Full-Service

The Quick Answer

For a full-service restaurant with table service, split checks, tip pooling, and inventory needs, Toast is the strongest overall choice — it's built specifically for restaurants, has the best table management and kitchen display system (KDS) integration, and has the largest network of restaurant-specific integrations. Square for Restaurants is the best value for small full-service restaurants under 40 seats that want low monthly fees and simple setup. Lightspeed Restaurant is the best option for restaurants with complex inventory needs or multi-location operations. All three charge 2.49–3.09% + $0.15 per transaction for card processing.

Toast POS: The Full-Service Restaurant Standard

Toast (pos.toasttab.com) is the most widely adopted POS among full-service restaurants in the US. It was built from the ground up for restaurant operations and shows it: table management (visual floor map, table status, timer for each table's occupancy), kitchen display system (KDS) integration that routes tickets to the right station, course-by-course firing, split check splitting by item or evenly, and tip calculation and pooling that integrates directly with payroll systems.

Toast hardware runs on proprietary Android-based terminals and handhelds — you're locked into their hardware ecosystem, which costs $799–$1,299 per terminal plus $649 for handheld devices. Software plans: Point of Sale (basic, $69/month), Point of Sale + Online Ordering ($110/month), and Build Your Own plan for larger operators. Payment processing: 2.49% + $0.15 per card-present transaction (non-negotiable with Toast — you cannot bring your own payment processor). Total first-year cost for a 2-terminal setup with handhelds: $8,000–$15,000 in hardware plus $828–$1,320 in software. Toast integrates natively with Restaurant365, MarketMan, 7shifts, QuickBooks, and most major restaurant platforms.

Square for Restaurants: Best Value for Smaller Concepts

Square for Restaurants (squareup.com/us/en/point-of-sale/restaurants) has matured significantly and is now a credible option for full-service restaurants, particularly smaller operations (30–50 seats) looking for low upfront costs and simple setup. Square's free tier handles basic table management, menu management, and payment processing at 2.6% + $0.10 per card-present transaction. The Plus plan at $60/month adds multi-location management, advanced reporting, and payroll integration.

Square's advantages: you can use your own iPad (reducing hardware cost to $0 for existing hardware), there's no long-term contract, the setup is extremely fast (1–2 hours versus 2–4 days for Toast), and Square's reporting is clean and accessible. Disadvantages for full-service: Square's KDS integration is less developed than Toast's, table management is functional but less visual, and the restaurant-specific integrations are fewer. For a 40-seat brunch concept or a wine bar with limited food service, Square is an excellent fit. For a 80-seat dinner-focused full-service restaurant with serious kitchen complexity, the limitations become apparent within the first month.

Lightspeed Restaurant: Best for Complex Inventory

Lightspeed Restaurant (lightspeedhq.com/restaurant) is the strongest POS option for restaurants with complex inventory management needs or multiple locations. Lightspeed's inventory module tracks ingredient-level stock depletion as orders are placed — when a server rings in a dish, the system automatically depletes the ingredient quantities from your inventory database. For a restaurant with 60+ menu items and multiple shared ingredients, this real-time depletion visibility is powerful for reducing waste and preventing 86s (running out of a menu item mid-service).

Lightspeed pricing: Restaurant Starter plan at $69/month, Essential at $189/month (includes advanced inventory), and Pro at $399/month (includes loyalty program and advanced analytics). Hardware is iPad-based (you supply your own), which reduces initial hardware costs significantly. Lightspeed integrates with Xero and QuickBooks for accounting, Planday for scheduling, and has an open API for custom integrations. The tradeoff: Lightspeed's interface is more complex than Toast or Square, requiring more staff training, and its US restaurant support is less robust than Toast's dedicated restaurant team.

Kitchen Display Systems and Table Management

A kitchen display system (KDS) replaces printed ticket printers with screen-based order displays at each kitchen station. The benefits: faster ticket communication, no lost or water-damaged paper tickets, the ability to track ticket times and identify bottlenecks, and full integration with your POS for order modification and void communication. A KDS setup costs $400–$800 per display (hardware + software); a typical kitchen might need 2–4 displays (one at each station: grill, sauté, expo, and optionally dessert/garde manger).

Table management — the visual floor map in your POS that shows table status, covers, ticket time, and server assignment — is a standard feature in Toast and Lightspeed and a functional but less visual feature in Square. For a restaurant with 15+ tables, a strong table management interface meaningfully reduces the cognitive load on hosts and managers. Look for: color-coded table status (available, occupied, check presented, table cleaning), timer display (how long each table has been seated), quick-access to any table's open check, and easy table reassignment when guests move. These features sound minor until the Friday night dinner rush when you're managing 20+ simultaneous tables and need to see the entire room at a glance.

Tip Reporting and Payroll Integration: Critical for Compliance

Tip reporting is where POS selection becomes a payroll and tax compliance issue. Your POS must accurately track: tips charged to credit cards per server per shift, tip pool contributions and distributions if applicable, server sales totals (used to calculate tipped minimum wage compliance), and hourly tip rate (for IRS 8027 reporting if you have 10+ employees). Toast handles all of this natively and integrates directly with Gusto, ADP, and Paychex for payroll processing. Lightspeed integrates with Xero and QuickBooks. Square integrates with Square Payroll ($35/month + $6/employee) and via API with QuickBooks.

For restaurants using a tip pool, your POS tip reporting needs to produce a clear audit trail showing gross tips collected, pool contributions per server, and pool distributions per BOH employee. Toast's tip pooling reports are the most detailed and restaurant-tested of the three platforms. Whatever system you choose, export and archive tip reports daily — they're required for IRS Form 8027 at year-end and for any wage and hour audit. A restaurant that can't produce accurate tip records from their POS faces serious compliance exposure in a Department of Labor investigation.
