Openfellas has developed its own digital learning and information platform as a single module Wiki that can be used for trainings, employee communicationFil, process descriptions, and work instructions for employees. Texts, files as well as video file formats may be attached. All self-created training documents or videos regarding the odoo system can, in turn, be linked directly to the system where they are pre-sorted and displayed in the module the user is currently working with. Thus, the user receives essential information for his potential questions listed in the current module.

The Odoo software has its own Accounting Module. Many German companies, however, leave accounting and tax matters to their tax consultants. Since most of these consultants have been trained and educated on DATEV, it is their software of choice.
