App di elaborazione delle fatture per una struttura di archiviazione

This is a compiled version of the app. The source code is available at https://github.com/Twinsen81/Invoiceman

The app is designed to be used in the following workflow:

1. An employee at the office receives an invoice from a supplier;

2. The employee enters data from the invoice into the backend's DB using a GUI app or a web frontend;

3. The supplier ships products listed in the invoice to the company's warehouse;

4. An employee at the warehouse finds the corresponding invoice in the app and accepts it for processing;

5. He or she scans or enters manually serial numbers (possibly, some other info) of the products using the app, then submits the collected data to the backend;

6. An employee at the office reviews the data and confirms the successful receipt of the products;

7. The data is kept on the backend for future reference (e.g. warranty service requests).
