client’s goals

We’ve provided many functionalities to Chimpy, among these, there are two tasks we would like to point out.

The first was the development of a logistic web-app that would track locations of power banks, purchases of new power banks and also identify those delivered to the storehouses. This app was also intended for accounting purposes – employees needed to assign QR (inventory) codes to every power bank and add them to the database.

The second task was to add several new functionalities to the admin panel used by Chimpy employees, so that they could generate invoices from their database.
