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

We like it free, simple, open source.

That's why we started developing siwapp. Siwapp is not meant to solve every single need of your business, neither it intends to end up as a full business manager application.

Our 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.

Siwapp is built on Symfony, a PHP web development environment, which heavily rests on MVC ideas (model, view, controller). This environment allows us to develop "Extreme Programming" techniques, as well as guarantee a proper application evolution in the future.

Siwapp's development is maintained by MARKHAUS, an Internet company with more than 10 years of expertise in the online world, but everybody is welcome to get involved!
