The cause:

One or more Pleo expenses has a category that does not exist in Fortnox (i.e, the respective "konto" is not active). It could be that it did exist, but was deactivated.

There are two alternative solutions:

  • In Pleo, change the category of the affected expense.


  • In Fortnox, re-activate the category/account:

    1. Click on "Register".

    2. Click "chart of accounts" (Kontoplan).

    3. Click on “inactive” (Inaktiva) to get a list of archived accounts:

    4. Find the affected account (Konto).

    5. Under "active" (Aktikt), switch from "no" to "yes":

    6. Click "save" (spara).
