Pricing

Free in 2026. Honestly priced after.

We're rolling out to the first customers now. Free for everyone who signs up in 2026 — this is how we learn what works. From 2027 we expect 299–599 kr/month per organization, cheaper than Fiken and Tripletex for equivalent functionality.

Frequently asked questions

Can't find the answer? Email admin@kantos.ai and a real person will reply.

How much does it cost?

Free for all of 2026 for anyone who signs up early. From 2027 we expect 299–599 kr/month per organization, depending on volume. No automatic conversion to a paid plan — we'll ask you first.

Is Kantax legal in Norway?

Yes. Kantax follows bokføringsloven and bokføringsforskriften. Receipts archive for 5 years, invoice numbering is gap-free, and all data is exportable as SAF-T on demand from the Tax Administration.

Can I migrate from Fiken / Tripletex / Conta?

Yes, but it requires some manual work in the 2026 version. We're building an importer for receipts, customers, and suppliers. Contact us — we'll help you personally through the switch during the early phase.

Do you integrate with my bank?

Yes, via Neonomics (aggregates nearly every Norwegian bank). Setup needs a little help from us per customer at the start, but the sync itself is automatic after that.

What about my accountant?

The year-end bundle exports your full fiscal year as CSVs in a ZIP. SAF-T XML is producible on demand. Full API access for accounting firms ships in 2027.

Why trust a new accounting tool?

Kantax is built by Kantos AS, a Norwegian-operated tech company. We use Kantax ourselves for our own books. Stack is modern (Next.js, Supabase), data lives in Supabase with daily backups. You can export everything at any time.

No stress. No auto-renewal.
