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, from 99 SEK per user a month via the Fortnox marketplace.

What can ChatGPT do in Fortnox?
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.
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 web and desktop, on a paid plan: Plus, Pro, Business, Enterprise or Edu. It isn't available on Free or in the mobile apps yet. The same connection also works in any other MCP client.
Do I need to turn on Developer mode?
On a personal Plus or Pro account, yes: custom connectors sit under Developer mode, which you switch on in Settings, Apps and Connectors, Advanced settings. On a Business, Enterprise or Edu workspace you don't: your administrator creates and publishes the connector (Apps, Create, Publish), then each member connects it from Apps and signs in with Fortnox.
How is a license counted?
A license is a user seat in one Fortnox company. If you use ChatGPT across several Fortnox companies you need a license per company. Fortnox checks your license and permissions each time you connect.
How is it billed?
99 SEK per user per month via the Fortnox marketplace. No setup fees and no per-call charges. 30-day money-back guarantee.
Connection not working?
Quick checklist: have you bought the license in the Fortnox marketplace, activated it via the activation link, and turned on the integrations module in Fortnox? Then check the ChatGPT side: a paid plan on web or desktop, Developer mode on, and on a workspace that your admin has shared the connector. Otherwise test with only the "Company information" scope to rule out a license issue with one of Fortnox's other modules.
