What is the Fortnox AI Connector?
The Fortnox AI Connector links your AI assistant to Fortnox so you can run the books in plain language. Ask it to find invoices, post entries or prepare VAT. The AI proposes, your app asks for your approval, and the change lands in Fortnox. And because all your companies live in the same connection, you can ask across them: which clients have overdue invoices, how revenue compares per company, who is behind on their books. One licence per user, unlimited companies, in Claude, ChatGPT, Microsoft Copilot or any MCP client.
// capabilities
Your Fortnox, in plain language.
Everything you'd otherwise dig through menus for is now a sentence away, in whichever AI assistant you or your firm already use. You don't have to be an accountant.
Ask anything
Find customers, suppliers, invoices and amounts. Ask like you'd ask a colleague, without hunting through menus.
Which customer invoices fell due last month?
Ask across all your companies
All your companies live in the same connection. Ask one question that covers the whole client list or group and get one answer.
Which companies have documents waiting in their inbox?
Create and approve
Create customer invoices, post entries and approve supplier invoices for payment. The AI fills in the details, you approve before anything is saved.
Post the receipt I just uploaded.
Pull the numbers
Summarize, compare periods and key figures, in one company or several side by side, without exporting to Excel.
Compare revenue per company in Q1.

Why accounting firms choose the Fortnox AI Connector.
Built for everyday life at a firm, where the same people work in many clients' Fortnox and the client list keeps growing.
Pay per consultant, not per client company
One seat covers a consultant's whole client list. Three consultants with thirty clients cost 747 kr a month, and taking on the next client costs nothing extra.
The whole client list in one question
The morning check across every client at once: overdue invoices, documents in the inbox, who is behind. One consolidated answer instead of thirty logins.
A new client connected in minutes
Activate the free app in the client's Fortnox, sign in and link. No API keys to manage, and the links follow the account.
The consultant's Fortnox permissions apply
No parallel permission model to administer. Each consultant can only do what the client has already allowed them in Fortnox, and everything is traceable at the client as usual.
Offboarding in one step
Remove a consultant and their client links and AI connections are revoked immediately. The seat goes on to the next person.
Each consultant picks their own AI
The licence follows the consultant, not the AI client. One can work in Claude, another in Copilot, on the same agreement.

Questions, answered.
Does one licence really cover all my companies?
Yes. A licence is a seat for one user, and that user can link an unlimited number of Fortnox companies to the same connection. This is the difference from the single-company connectors, where each user needs a licence per Fortnox company.
Which AI clients does it work with?
Any client that speaks MCP: Claude, ChatGPT, Microsoft Copilot and more. The licence is independent of the client, so you can use one today and switch tomorrow without buying anything new.
How is it billed?
By Sidcom, by card, 249 kr per user and month or 2 390 kr per user and year, excluding VAT. It does not go on your Fortnox invoice. You manage seats, billing and invoices yourself at fortnox.sidcom.ai.
How does the free trial work?
Every new organisation gets 7 days free, no card needed. When the trial ends, nothing is charged. Access simply stops until you choose to start a subscription.
How does an accounting firm work with it?
Each consultant gets a seat and links the client companies they work with, signing in with their own Fortnox user per company. Permissions and traceability follow that Fortnox user in each client, exactly as if they were working in Fortnox directly.
Can the AI compare my companies?
Yes. Ask one question across your connected companies, such as which clients have overdue supplier invoices, and get one consolidated answer. Comparisons cover up to 12 companies per question.
We already have Claude or ChatGPT connector licences. Should we switch?
If you work in a single Fortnox company, keep them, they are the simpler buy at 99 kr per user and company via the Fortnox marketplace. When the same people work across several companies, one Multi-Company seat is usually cheaper from about three companies, and much simpler to manage.
What happens when someone leaves the firm?
Remove them under Members at fortnox.sidcom.ai. Their company links and AI connections are revoked immediately, and their seat can be assigned to someone else.
Is my clients' data safe?
The books stay in Fortnox. Data passes through the connection while a question runs and is not stored at Sidcom. Fortnox sign-in tokens are encrypted, no passwords are stored, and a data processing agreement is available on request.
Connection not working?
Check that the free app is activated in Fortnox App Market for the company, and that you hold a seat. The quickest check is to ask your assistant about your licence. It can read your organisation's status, trial and seats even when everything else is blocked.
All your books. One sentence away.
Try the Fortnox AI Connector free for 7 days, no card needed. One company or many, you're up and running in minutes.
