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 connects ChatGPT, Claude, or Cursor to your Fortnox company through MCP so your AI assistant can fetch, analyse, and request changes. By default, a change opens a browser approval preview; a company can enable auto-approve for immediate execution, subject to Fortnox permissions and Nordsynk access policy.
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.
Add Nordsynk under Plugins in ChatGPT
In ChatGPT, open Customize → Plugins, click Add, and choose Create custom MCP server. Enter Nordsynk's endpoint URL as the Server URL and keep OAuth as the authentication method. ChatGPT discovers the remaining sign-in details from Nordsynk's server. To show Nordsynk's logo in ChatGPT, upload https://nordsynk.se/nordsynk-favicon.png as the icon.
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. The first time, ChatGPT asks for permission to use Nordsynk: choose Allow once or Always allow.
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.
Frequently asked questions about 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 servers. Open Customize → Plugins in ChatGPT: if the Add menu offers Create custom MCP server, Nordsynk works with your account.
Can ChatGPT write to Fortnox?
Yes. Nordsynk exposes the full Fortnox API, including changes such as creating invoices and bookkeeping records. By default, each change opens a browser approval preview. A company can enable auto-approve so changes run immediately instead; Fortnox permissions and Nordsynk access policies still apply.
What happens to my Fortnox data in ChatGPT?
Your AI assistant receives Fortnox data needed to answer your question. Nordsynk also stores data for selected workflows: protected SIE/ledger snapshots support reports and DataLinks, change details support review and execution, and files sent through Dropzone are staged temporarily.
