You can connect your Wise Business account to Fortnox to automatically sync your transaction data. This saves you time on manual data entry and helps keep your multi-currency bookkeeping up to date.
You need to create a separate bank account in Fortnox for each currency you choose to connect, allocated within the Swedish BAS bank account range (1920–1999).
You must have your Wise currencies opened and connected to Fortnox for your statements to sync automatically.
We will sync your transactions as 'Vouchers' (Verifikationer). To find them go to Menu -> Accounting -> Vouchers
The connection is securely facilitated by our partner Chift, which acts as an intermediary to ensure reliable, automated data transfer.
Which countries is the Fortnox integration available in?
Fortnox is the leading cloud-based accounting software in Sweden and one of the largest in the Nordics. The integration is aimed at businesses based in Sweden that use Fortnox, where the company base currency is SEK.
What do I need in Fortnox to use the integration?
You'll need two Fortnox licenses:
| License | Requirement |
|---|---|
| Accounting (Bokföring) | Included in every Fortnox package. |
| Integration (~17 EUR/month) | Included for free in Mellan, Stor, Mini+, Mellan+, and Stor+. On the Mini and Liten packages it's a paid add-on (~17 EUR/month). |
There's no strict minimum package required — even the Mini package can add the Integration license as a standalone add-on. If you're on Mellan or above, the Integration license is already bundled in at no extra cost. For the latest pricing, see the Fortnox pricelist.
