A: No. Freight (Frakt) and the administration fee on a Fortnox order, offer or invoice are not synced to Upsales. The Upsales order only gets the rows from the Fortnox document, so these amounts are not included in the order value.
Upsales does not send freight or an administration fee to Fortnox either. Set them in Fortnox.
With Fortnox Premium, you can turn on Aktivera Total på faktura in the app settings. The invoice total from Fortnox is then saved in the order field Total in Upsales.
