What is the ChatGPT Fortnox Connector?
The ChatGPT Fortnox Connector links OpenAI's ChatGPT to your Fortnox account so you can run your books in plain language. Ask ChatGPT to find invoices, post entries or prepare VAT. ChatGPT proposes each change and asks for your approval before anything is written to Fortnox. It works in ChatGPT on web and desktop with a paid ChatGPT plan that has connectors enabled, 99 kr per user and company a month via the Fortnox marketplace.

You ask. ChatGPT proposes. You decide.
We completely understand that letting ChatGPT near your books can feel daunting. It does not have to be. Here is how it works: the connector can do exactly what you are allowed to do in Fortnox, and every change passes you first.
Fortnox OAuth
No passwords stored with us. All sign-in goes through Fortnox.
Your own permissions
ChatGPT can do exactly what you can do in Fortnox, no more, no less.
You have the final say
ChatGPT proposes, and asks for your approval before writes are sent to Fortnox.
Traceable in Fortnox
All changes are made through your own Fortnox user and show up in Fortnox as usual.
Swedish supplier, built for GDPR
Sidcom is a Swedish company. No bookkeeping data is stored at Sidcom.
Essentially all of Fortnox is available. ChatGPT 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 ChatGPT before it is sent. See the full module table, 22 Fortnox modules with exactly what you can do in each.
Can ChatGPT change my books without me?
No. ChatGPT proposes changes and 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. ChatGPT only acts within your existing Fortnox permissions, and all changes are made through your own Fortnox user and show up in Fortnox.
Which ChatGPT plans and apps does it work with?
ChatGPT on a paid plan: Plus, Pro, Business or Enterprise. The connector is added at chatgpt.com in your browser, not in the ChatGPT app, and is not available on the free plan. The same connector also works in other MCP clients.
Do I need to turn on Developer mode?
No, not any more. In today's ChatGPT you add the connector as an MCP app: Plugins, Add, Create MCP App. The steps are the same on Plus, Pro, Business and Enterprise. Follow the step-by-step guide.
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 ChatGPT 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, or I land on the purchase page. 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. If you land on the purchase page when reconnecting, the subscription is still there, the seat is taken by another user. 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. Add the connector at chatgpt.com in your browser, not in the app. If the connection drops, try another browser or temporarily turn off your antivirus' HTTPS scanning. See the troubleshooting under the guide.
