Linux.com covers Kraft, an administration software package for small and medium businesses (SMB), covering activities such as customer management, document workflow, material management, calculations for positions and templates for most of these. Linux.com concludes
"Kraft takes some of the drudgery out of tracking work offers and invoicing. If you are a KDE user, being able to use a single contact manager for issuing your invoices will cut down on your mail merging worries. But Kraft's handling of VAT/GST could be improved." We will have to add to that, that you do not need to be a "KDE user" already to use Kraft. As with all KDE applications, it runs just fine on other Free desktops too. The KDE e.V. uses craft for membership management, and gets first-hand support by Kraft's main developer, our very own Klaas Freitag.
