What you can ask ChatGPT about your Fortnox data
Can you chat with Fortnox?
With Nordsynk — yes. Without it, Fortnox has a support chat but no way to query your own bookkeeping data via a chat interface. Nordsynk solves this: you connect ChatGPT (or Claude, or Cursor) to your Fortnox tenant via MCP, and your AI client can then fetch, analyse, and create Fortnox data after confirmation directly in the conversation.
Not Zapier. Not Make. One tool.
Zapier and Make rank for "fortnox chatgpt" but they are automation platforms: you build separate Zap chains for each operation, and ChatGPT is just one of thousands of apps to wire together. Nordsynk is an MCP server — ChatGPT (or Claude) connects to the current Fortnox API surface as a single tool. No Zaps to configure, no automation logic to maintain.
Connect Fortnox to ChatGPT in 3 minutes
Nordsynk is configured once by a Fortnox admin. Each user then connects from their own ChatGPT settings.
Activate Nordsynk in the Fortnox portal
A firm lead or finance manager opens the Fortnox portal and activates Nordsynk as an integration. It takes under a minute.
Open ChatGPT Apps and create a new app
In ChatGPT, go to Settings → Apps → Create app. Enter Nordsynk's endpoint URL as the MCP Server URL and select OAuth as the authentication method. ChatGPT discovers the remaining OAuth details from the Nordsynk server.


Sign in to Nordsynk
ChatGPT opens Nordsynk sign-in. Use your email, then approve all or a subset of your connected companies. You can now ask ChatGPT about those companies directly in chat.
Secure and Fortnox-billed
Every connection is authenticated via Fortnox OAuth 2.0. Nordsynk verifies that the user has an active seat in the Fortnox portal before the session starts. Billed directly via Fortnox — no separate credit card.
Vanliga frågor om Fortnox + ChatGPT
Can you chat with Fortnox?
With Nordsynk you can use ChatGPT, Claude, or Cursor as a natural-language interface to your Fortnox data. You ask in plain language and Nordsynk calls the Fortnox API on your behalf.
Is Fortnox reliable to integrate with?
Fortnox is Sweden's largest cloud-based bookkeeping platform with 600,000+ customers and a well-established REST API. Nordsynk uses the official Fortnox OAuth 2.0 flow and never handles your Fortnox password.
Does Fortnox have a CRM?
Fortnox has a customer register and invoicing features but is not a dedicated CRM. With Nordsynk you can use ChatGPT to search and analyse customer data in Fortnox as part of a broader workflow.
Which ChatGPT plan do I need?
You need a ChatGPT plan that supports custom MCP apps and connectors. Currently that means ChatGPT Plus, Team, and Enterprise. Check your plan's settings — if you see the Apps section under Settings, Nordsynk will work.
Can ChatGPT write to Fortnox?
Yes. Nordsynk exposes the full Fortnox API including write operations. You can create invoices, supplier records, and bookkeeping transactions via ChatGPT. All write operations require you to confirm the action in the conversation before they are executed.
What happens to my Fortnox data in ChatGPT?
Your Fortnox data is sent to ChatGPT to answer your question, just like pasting text into a conversation. Nordsynk does not store your Fortnox data — we only handle authentication and forward the API responses. Review OpenAI's privacy policy for how ChatGPT handles conversation data.
