Kenzer – Hybrid POS / ERP Desktop App

Kenzer is a hybrid POS / ERP desktop application built on ElectronJS with a Frappe ERPNext backend running locally via Docker. It handles 100k+ products and customers without any UI slowdown.

Startup time was cut by 50x through multi-threaded data fetching at boot and a delta-sync caching strategy that only fetches records updated since the last session.

The app supports billing, invoicing, supermarket mode, barcode scanning, ZATCA integration, wholesale operations, and sales returns. PDF printing is near-instant (~2 seconds) with HTML client-side rendering, multiple printer driver support, and compatibility with all common thermal POS printers and barcode scanners. Both Arabic and English are supported.
