Retailers and restaurants in Guadalajara are moving to Posnic, a complete POS (punto de venta) software that costs nothing and hides nothing. It is open source, runs fully offline on your own computer, and handles sales, inventory and reports without a monthly fee.
Prices, receipts and reports display in pesos with local number formatting, configured once per store.
Scan-and-sell with barcode scanners, or tap through sales on touch screens and tablets. Both are first-class.
Live stock with every sale, low-stock alerts, purchase receiving and a full movement history behind each number.
Table ordering, kitchen tickets and hybrid retail-plus-dining in the same software, at no extra cost.
Run one shop or a chain across Mexico: each store keeps its own settings, consolidated in cloud dashboards when you subscribe.
The complete application is public on GitHub under AGPL-3.0. No trial, no feature locks, no telemetry.
Posnic for your business: Grocery · Restaurants · Cafes · Fashion · Pharmacy · Electronics · Hardware
Yes. Posnic Community Edition is free forever, everywhere including Guadalajara. It is open source under AGPL-3.0 with all features included. Posnic Cloud, the optional sync and backup service, is the only paid product.
Yes, completely. The software runs on your own computer and needs no internet connection to sell, print receipts or manage stock. Cloud sync, if you use it, catches up automatically when the connection returns.
Posnic uses configurable tax groups, so VAT (IVA) rates are set once and applied automatically, with inclusive or exclusive pricing and tax-wise report summaries.
