Is Square POS really free?

Square's POS software is free, but you pay 2.6% + $0.10 per card transaction. This is how Square makes money. For a business processing $50,000/month, that is roughly $1,350/month in processing fees. Odoo charges for the ERP but lets you choose payment processors with potentially lower rates.

Can I use my own payment processor with Square?

No. Square requires exclusive use of Square payment processing. Odoo POS integrates with multiple payment providers (Adyen, Stripe, Worldline, Six) so you can negotiate rates or use your preferred processor.

Which POS is better for restaurants?

Square for Restaurants ($60/location/month) and Odoo POS Restaurant (included in ERP price) both offer table management, floor plans, and kitchen display. Odoo's restaurant features are included in the base price, while Square charges separately.

Does Odoo POS work offline?

Yes. Odoo POS is a Progressive Web App (PWA) that can operate offline. Orders sync when connectivity is restored. Square POS also offers offline mode with transaction queuing.

Payment Processing

This is a critical differentiator. Square requires you to use Square's payment processing at 2.6% + $0.10 per transaction. There is no option to use a different processor. Odoo POS integrates with any payment terminal (Adyen, Stripe, Worldline, Six) and lets you negotiate your own processing rates — potentially saving thousands per year for high-volume businesses.

# Payment Processing Cost (Monthly Sales: $50,000):
# Provider        | Rate            | Monthly Cost
# Square          | 2.6% + $0.10    | ~$1,350
# Adyen (Odoo)    | 1.5-2.0%        | ~$750-1,000
# Stripe (Odoo)   | 2.7% + $0.05    | ~$1,375
# Negotiated rate | 1.2-1.8%        | ~$600-900

Ease of Setup

Square wins hands-down for setup speed. Download the app, plug in the reader, and start selling. Odoo POS requires configuring the POS within the ERP context — products, payment methods, accounting journals, and inventory locations. The trade-off is operational integration vs. immediate usability.

Inventory Management

Square tracks stock quantities and sends low-stock alerts. Odoo POS connects to the full Inventory module with multi-warehouse, real-time stock levels, automated reordering, lot tracking, and barcode scanning. For businesses with serious inventory needs, Odoo is significantly more capable.

Restaurant Features

Both offer restaurant-specific features. Square for Restaurants ($60/location/month) provides table management, coursing, and kitchen display. Odoo POS Restaurant (included in ERP price) provides floor plan designer, table management, split bills, kitchen screen, and tip management.
