CantinaPOS transforms Google Sheets™ into a fully functional point-of-sale (POS) system for small businesses, combining simplicity with powerful sales and inventory management features. Through an intuitive sidebar interface, users can manage products, add items to a cart, and process orders in real time — all within Google Sheets™.

The app automatically calculates subtotals, applies customizable tax rates, and computes accurate totals for billing. Orders are saved to an “Orders” sheet, and stock levels are updated in the “Items” sheet for seamless inventory tracking. The “Settings” sheet lets you configure tax rates, currency, payment methods, and now, language preferences — with support for English, Spanish, French, and Bahasa Indonesia.

CantinaPOS is designed for small cafés, retail stores, and pop-up stalls looking for a lightweight, affordable POS system with no contracts, offline usability, and direct Google Sheets™ integration.

Paid users enjoy quick in-app chat support, while all users can reach out via email for assistance. Whether you’re tracking daily sales, managing taxes, or customizing your POS interface, CantinaPOS keeps your business data organized, accessible, and efficient — all within the Google Workspace ecosystem.
