All activity in the Oxalis Community is funded by its members, by fees determined by the Oxalis Community. An overarching principle is to keep administration to a minimum, to ensure that funds are spent on improvements, bug fixing and development of the software – to benefit all implementers.

By joining the Oxalis Community, you are making an active contribution to the continued implementation and use of Peppol, reducing barriers to interoperability and promoting digitalization.  As Gold member, you can influence the direction and further development of the software by representation and voting rights.
