Fortnox settings before starting integration

This article describes the most common configuration steps that should be completed in Fortnox before starting an integration.

1. Create a Fortnox user with the correct permissions

1a. Administer users

Create or select the user that will be used for the integration.

1b. Add licenses for integration and:

  • Orders

  • Invoices

  • Accounting

  • Integration

1c. Assign licenses to the user and enable all required permissions

Ensure the integration user has continuous access to all modules needed by the integration.

Important: Do not modify or delete this user after integration setup. Changing permissions, licenses, or the user itself will cause the integration to stop working.


2. Add all currencies and enable automatic currency rate updates

You must add all currencies you will transact in and enable automatic exchange rate updates to ensure accurate accounting and invoicing.

3. Set up all VAT rates

Review and configure all VAT rates required for your sales markets.

4. Set up Sales accounts and VAT mapping for EU OSS

To comply with EU One-Stop-Shop (OSS) requirements, create separate sales accounts for each EU country and configure correct VAT mappings. This ensures accurate VAT posting and reporting for cross-border B2C sales.

Todo: Make a list of the sales accounts that you will use. We will need to map it during onboarding.

5. Add payment method accounts

For proper posting of payments from providers such as Svea, Kustom, Walley, Qliro, Shopify Payments, and similar gateways, you must add each payment method (betalsätt) in Fortnox and map it to a account.

Accounting note

  • Typically, payment methods are assigned to a 19-series account (e.g., 19xx), as these represent interim cash equivalents.

  • Alternatively, some companies prefer using 15-series accounts (e.g., 15xx) to separate payment claims from cash-equivalent balances.

The payment method account should not be the same as the actual bank account. Payment provider payouts represent funds held by the provider until transferred, not immediate bank deposits.

Fortnox’s bank integration manages real bank accounts separately, which is why payment provider accounts must be mapped independently.
