Questions, answered.
What can Claude do in Fortnox?
Essentially all of Fortnox is available. Claude can search customers, suppliers and invoices, see what's paid and unpaid, create customer invoices, post entries, approve supplier invoices for payment, and export bookkeeping data as SIE files. You approve every write in the app before it is sent. See the full module table, 22 Fortnox modules with exactly what you can do in each.
Can Claude change my books without me?
No. Claude proposes changes and your Claude app asks for your approval before writes are sent to Fortnox.
Is my data safe?
Yes. You sign in with Fortnox OAuth and Sidcom never stores your password. Claude only acts within your existing Fortnox permissions, and all changes are made through your own Fortnox user and show up in Fortnox.
Which Claude apps does it work with?
The connector lives on your Claude account rather than in one app, so it follows you wherever you use Claude: the web, the desktop app, mobile, Claude Code and Claude for Excel.
How is a license counted?
A licence is a user seat in one Fortnox company. If you work across several companies you activate the connector in each one and hold a licence per company, all on your Fortnox invoice, and no integration licence is needed. If you are an accounting firm with many client companies per consultant, AI Connector for Bureaus is built for that instead. Fortnox checks your licence and permissions each time you connect.
Can I use the connector across several Fortnox companies?
Yes. Activate the connector in Fortnox App Market for every company you work in, your own or your clients'. You get one licence per user and company, all on the same Fortnox invoice, and no integration licence is needed in any of them. Then add the companies in Claude and ask across several of them in one question.
I have Digital Byrå, which company should I choose?
With Digital Byrå your company is listed twice when you choose a company in Fortnox, with different agreement numbers. Choose the one that is not marked Digital Byrå. If you connect to the Digital Byrå version, the licence is not found.
It says the licence is missing. Why?
The licence is assigned automatically when you connect, but only if the company has a free seat. A new user connecting needs the company to have bought enough licences. How to check for free licences and buy more.
How is it billed?
99 kr per user and company per month via the Fortnox marketplace. No setup fees and no per-call charges. 30-day money-back guarantee.
Connection not working?
Check that the licence is bought and activated on the company, that you choose the company without the Digital Byrå mark, and that there is a free licence. On Team and Enterprise, by default only an administrator can add connectors. See the guide and troubleshooting.
