Should you use Kvitto & Utlägg or an add-on?

If you are happy to move to the Fortnox company card, Kvitto & Utlägg is simple and well integrated. If you keep cards from your bank, or your projects and cost centres need to be right without the submitter choosing them, an add-on that codes from history is the better fit.

How does Vergo connect to Fortnox?

Vergo connects directly through the public Fortnox API and records coded card spend as vouchers, with account, VAT, cost centre and project. Transactions are ready to code the moment they happen — no waiting for clearing — and once they clear, they sync into Fortnox.

Frequently Asked Questions

Is Vergo a Fortnox integration?

Vergo is standalone and connects through the public Fortnox API.

Can Vergo run alongside Kvitto & Utlägg?

Yes, though most teams using Vergo for card spend do not need both.

Do we need new cards?

No. Connecting your existing cards involves no card applications, no re-issuing and no banking change.

Does Vergo handle supplier invoices?

Yes. Card spend, employee reimbursements and AP invoices run through one coding model — same coding, same review, one reconciliation — and payment stays on the rails you already use.

Where are the integration details?

On the Fortnox integration page.
