Siwapp is an open source web application meant to help manage & create invoices in a simple, straightforward way.

Siwapp is not meant to solve every single need of your business, neither it intends to end up as a full business manager application. The goal is to get just one thing right: Invoices. A basic need for every business.

This web application will also be able to work as a module -interconnected through its API- to many other business management applications which takes care -the easy way- only of the billing of the company.
