Detailed Overview

Designed for real-world retail, MiniPOS Offline stores transactions, products, and settings in a local data store so cashiers can keep selling when Wi-Fi drops. The app later syncs sales and inventory with your back-office (through configurable REST endpoints). Role-based access controls protect sensitive operations (refunds, price overrides), while printable Z-reports make reconciliation fast at shift end.

The license system is purpose-built for distributed teams: activate devices by code or URL, bind licenses to a device fingerprint, enable trial periods, and apply grace windows when offline. Everything is kept lightweight for reliability and easy maintenance.
