Important to know

For the integration to work you need to order the integration (API) module from Fiken. This can be done from you application website in Fiken.

Moment = master. This means that the invoice number, customer number and project number will be transferred into Fiken. Do not change the numbers in Fiken.


  • Projects require a start date before these will be transferred to Fiken.

  • Project names must be unique in Fiken, Moment will check when creating projects that the name is unique.


  • Invoices will be registered as entries in the journal. This requires that financial accounts in Moment and Fiken are the same, and that the VAT code is defined for these in Moment. 7740 (Øreavrunding) does not need this defined.
