GPOS Van - Offline first POS tablet application

Overview

The GPOS Van Tablet App is a tablet-based van sales solution built on ERPNext, designed for wholesale and retail businesses that supply goods to customers through van sales operations.

Using iPad or Android tablets, sales teams can easily create invoices, and update customer accounts directly from the field.

Many distribution activities happen in remote areas with unstable or no internet connection. To solve this, the app supports offline billing, allowing users to continue sales without interruption. All data is securely stored and automatically synced with ERPNext whenever an internet connection becomes available.

Additionally, the app generates ZATCA-compliant invoices with QR codes, ensuring full compliance with Saudi Arabia’s e-invoicing regulations.

Overall, the GPOS Van App acts as a complete bridge between field sales operations and ERPNext, enabling businesses to run efficient, accurate, and uninterrupted van sales workflows.
