// what_you_can_do
What you'd otherwise hunt for in Fortnox menus is now a question. You don't have to be an accountant, and you don't have to learn a new interface, because you work in the AI app you already have open.
Customers, suppliers, invoices, balances and periods. Ask the way you'd ask a colleague who knows the books inside out.
Which customers have overdue invoices?
Link every company you work in, your own or your clients', and ask one question that covers all of them. You get one consolidated answer without signing in again or switching tabs.
Which companies have documents waiting in their inbox?
Create customer invoices, post documents, approve supplier invoices and add new customers. The AI fills in the details, you approve.
Post the receipt I just uploaded.
Summarize, compare periods and surface key figures right in the chat, with no export to Excel and no report to build.
Compare revenue against last year.
// the_safeguards
We completely understand that letting an AI 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, every change passes you first, and nothing happens behind your back.
The AI proposes the change and your app asks for your approval before it is sent to Fortnox. It can read freely; it cannot change anything on its own.
You sign in with Fortnox and the connector gets precisely your rights, no more and no less. If you can't approve invoices, neither can the AI.
You tick what the AI may reach when you connect. If you want it to read invoices and nothing else, that works.
Everything goes through your own Fortnox user and shows up in Fortnox exactly as if you had done it yourself.
We store no bookkeeping data. No passwords either — sign-in goes through Fortnox.

Every review comes from the Fortnox marketplace, quoted as written, in Swedish.
I am very happy with the ChatGPT Connector. The Fortnox integration works smoothly and saves me a great deal of time in the daily work at the accounting firm. Being able to search, analyse and work with the bookkeeping straight from ChatGPT is enormously valuable. Installation went well and support has been fast, personal and helpful. Warmly recommended!
With the ChatGPT Connector we have been able to build clear and dynamic rules that help us handle our accounting in Fortnox efficiently and predictably. After giving ChatGPT a set of high-quality references and documentation on accounting and tax rules, it is now like having continuous access to an accounting expert who helps us book correctly, according to both BAS and the Swedish Tax Agency's rules. Checks and follow-ups are a breeze.
As an organic food shop we work a lot in Fortnox Inventory, with goods received from supplier invoices and goods dispatched through our sales channels, to keep our flow of goods in order. The ChatGPT Connector finally let us automate our complicated matching of items between the supplier invoices and our item register. It has also helped us raise the quality of our work. We are delighted with how the integration helps us work more efficiently.
A whole new world opened up when we connected the ChatGPT Connector. We can now tie finance, purchasing and sales together and build our own AI agents that work directly with our systems. We have also had really good support and guidance from Johan and his team throughout. Warmly recommended!
A fantastic integration that saves me an enormous amount of time. I can search, analyse, write invoices, interpret, book and pay supplier invoices and so on, straight through ChatGPT. The integration is a gift from God, could it be because I pay church tax 🫣😃 Thank you Sidcom, thank you 🫶🫶 Support has also been personal and helpful. Five out of five stars!
A great connector that lets me easily pull out reports and staff lists, and book entries straight in Claude.

Claude, ChatGPT and Copilot each have their own connector, but they cover the same modules, follow the same security model and cost the same. The only difference is which app you work in.
// at_a_glance
Yes. The connectors are separate, but they cover the same Fortnox modules, so the module table holds equally for the Claude Fortnox Connector and for Copilot. What differs is which app you work in, not what the AI can reach.
The one for the AI you already use. Claude, ChatGPT or Copilot, the same modules and the same price. If you are an accounting firm with many client companies per consultant, Fortnox AI Connector: Unlimited is built for that instead.
99 kr per user and company per month, via the Fortnox marketplace. No setup fees, no per-call charges, and a 30-day money-back guarantee.
No, not for the connectors in the Fortnox marketplace. They are billed on your Fortnox invoice, and those integrations require no separate integration licence. For a tailored setup directly from us each company needs one, and we work through that in advance.
Yes. Activate the connector in each company, one licence per user and company, all on the same Fortnox invoice. If the same people work across many companies and you have your own requirements, get in touch: there is a setup we build together with you.
No. The AI proposes changes and your app asks for your approval before writes are sent to Fortnox. Everything also happens within your own Fortnox user's permissions.
Buy in the Fortnox marketplace and the licence is invoiced by Fortnox, so you don't have to onboard Sidcom as a supplier. If we agree on a tailored setup, the contract and invoice are with us. Either way the connector is built and operated by Sidcom.
Yes. Sidcom is a Swedish company, built for GDPR. No bookkeeping data is stored with us, it stays in Fortnox.
No new platform to learn and no project to run. You activate the connector in Fortnox and ask your first question in the AI app you already have open.
