What the BrandGate-Fortnox integration does for credit note VAT flow

A credit note can involve different VAT rates per article (food 12%, regular 25%) or different accounts per country. BrandGate calculates reversed VAT per line and books to the right account in Fortnox. A credit note can involve different VAT rates per article (food 12%, regular 25%) or different accounts per country. BrandGate calculates reversed VAT per line and books to the right account in Fortnox. Use case: Wholesalers with complex returns and VAT reversal. No Zapier middleware, no manual export, no separate licensing — the Fortnox integration is included in BrandGate Starter from 990 SEK/month. You pay your normal Fortnox license separately to Fortnox. Sync time per operation is under 2 seconds. During Fortnox maintenance (typically Friday evenings) operations queue locally and replay when service is back.

30-minute setup

**Step 1** — Authorise Fortnox via OAuth (no API keys to handle manually). **Step 2** — Configure the credit note module under Orders > Returns. BrandGate auto-suggests sensible defaults based on your Fortnox chart of accounts. **Step 3** — Test with a sandbox invoice. BrandGate creates a test distributor and generates a test invoice so you can verify the format before flipping live. **Step 4** — Activate live sync. From now on credit note VAT flow is handled automatically for every order. Total setup time: 30 minutes in the normal case.

Common pitfalls to avoid

**Duplicate customers on org changes.** If a distributor changes org. number (common at company splits) BrandGate may create a new customer instead of matching. Fix: use Fortnox's customer-match flag manually once. **Wrong VAT rate on export orders.** On B2B exports to the EU, reverse charge must apply. BrandGate auto-detects this but requires the distributor to have a valid VAT number registered — missing it means the invoice goes out as Swedish 25% by mistake. **Sync pause during Fortnox maintenance.** Fortnox has scheduled maintenance windows. BrandGate queues and syncs when the service is back — no manual action needed but worth knowing the invoice can land with a few minutes' delay.

For your accountant

The BrandGate-Fortnox integration is designed to meet Swedish accounting standards and Skatteverket's requirements. Specifically for credit note VAT flow: - **Bokföringslagen Chapter 4** — all business events register in real time (under 2 seconds), with audit trail showing who placed the order and when the invoice was generated. - **Skatteverket VAT rules** — automatic classification against the right VAT account, OSS reporting for B2C within the EU. - **SIE4 export still available** — for accountants who want monthly dumps in addition to the live sync. For accountants familiar with Fortnox: BrandGate's integration doesn't change how Fortnox works — invoices look exactly like they were entered manually.
