How Fortnox integration works
Once connected, Spacebring syncs newly issued invoices to Fortnox in real time as unbookkept invoices, and credit notes for unpaid invoices once you have bookkept the invoice in Fortnox.Voiding an invoice in Spacebring doesn’t sync to Fortnox. To correct an invoice, issue a credit note in Spacebring, which syncs once the invoice is bookkept in Fortnox.
How invoices sync
The integration maps Spacebring invoice data to Fortnox as follows:How credit notes sync
Spacebring syncs a credit note issued for an unpaid invoice as a full credit of that invoice in Fortnox. Fortnox creates the credit from the invoice, copies its rows, and links the two documents. The credit note syncs only when both conditions hold:- The invoice is already bookkept in Fortnox, since Fortnox can only credit a bookkept invoice. Otherwise the credit note fails to sync, and the notification asks you to bookkeep the invoice and create the credit note in Fortnox yourself.
- The credit note covers the whole invoice, since Fortnox credits an invoice in full. A credit note for part of an invoice fails to sync. Create the partial credit in Fortnox yourself.
Disconnect the Fortnox integration
- Click the menu (…) next to the location’s name > go to Integrations.
- Select Fortnox > press Disconnect and confirm your choice.
Disconnecting stops the sync but doesn’t revoke Spacebring’s access in Fortnox. To revoke it, remove Spacebring from your company’s integrations in Fortnox.
FAQs
Why is nothing syncing after I connected Fortnox?
Why is nothing syncing after I connected Fortnox?
The connection stays incomplete, and nothing syncs, until an account is selected for every invoice item type on the Integrations > Fortnox page: Bookings, Event tickets, Shop products, Packages, Subscription items, and Custom. Missing even one stops invoices syncing, including item types you don’t sell.If a specific invoice fails rather than everything, the notification names the cause. The most common ones are a VAT rate or a currency on the invoice that isn’t set up in your Fortnox company — see notifications about integrations’ failures.
