The integration between Nitesoft and Fortnox can only fetch payments. Which means that every transaction linked to an invoice in fortnox needs to be registred as a payment in order for the systems to sync properly.
This applies for example to commissions, card fees, exchange rate diffrences and rounding.
1. In fortnox add the account as a payment method (see 'Inställningar>Fakturering>Betalsätt').
2. When you register for example a comission on an invoice, do it as a manual payment in fortnox.
open the invoice and go to 'Inbetalningar' and register amount and select for example comission payment method.
