Siwapp is an free opensource invoicing tool. Most online invoicing tools are not free, so I started my search for a free web application.

Siwapp needs to be installed on a webserver, so if you don’t have the knowledge to do this, you probably know someone who can. For example your webmaster, a friend, colleague or family.

Once installed, you can make as many invoices as you want. It has a customisable invoicing layout, you can make deals, recurring invoices, keep track of payments, VAT statistics,…

It doens’t have many features but for a small company or an independent freelancer it fits perfectly.

If you need some help installing this software or you need some webspace, don’t hesitate to contact me!
