Searching for POS (punto de venta) software in Monterrey? Posnic gives Mexico businesses the full package: fast checkout, inventory, VAT (IVA) handling and reports, free forever and open source, with billing that keeps working when the internet does not.
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.
Everything lives in a local database you control, exportable to CSV any day, with a documented sync protocol.
Thermal receipt printers, barcode scanners, label printing, weighing scales and cash drawers are all supported.
Checkout in Monterrey never waits on the internet. Posnic runs on the shop computer, keeps billing through any outage, and syncs later if you use Posnic Cloud.
Posnic for your business: Grocery · Restaurants · Cafes · Fashion · Pharmacy · Electronics · Hardware
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.
Any Windows computer. Standard USB barcode scanners, thermal receipt printers, cash drawers, weighing scales and touch screens all work. Existing hardware from a previous system usually carries over.
