The bureau's routine,
in minutes instead

Run your clients' Fortnox straight from Claude or ChatGPT. You ask, reconcile, invoice and post in plain language, in every client company you work in, without hunting through menus.
249 kr per user and month, unlimited client companies.
Integration partner Built by Sidcom, not published by Fortnox.
The bottleneck is rarely the knowledge. It is the clicking.
With thirty clients in Fortnox the day goes into menus. Log in, find the document, reconcile, jump to the next company, start over. Fortnox AI Connector for Bureaus puts a layer on top of that work. You write what needs doing, in Claude, ChatGPT or Copilot, and the AI reads and writes in the right client company. No new platform to learn, no second permission model to administer and nothing that bypasses Fortnox: you sign in with your own Fortnox user in each client and approve every change before it is sent.
// the_bureau_month
What you do every month, without hunting through menus.
The examples come from an ordinary month at a bureau. Nobody needs to know Fortnox inside out, and nobody has to learn a new system.
The morning check across every client
One question covers every client company you work in. Who has overdue invoices, where are documents waiting, which companies are done. One answer instead of thirty logins.
Which of my clients have overdue customer invoices?
Receipts and supplier invoices
Post receipts and supplier invoices and approve them for payment. The AI proposes the entry, you approve before anything is saved in the client's Fortnox.
Post the receipts sitting in the inbox at Acme AB.
Invoicing and reminders
This month's fee invoices drawn from last month's basis, and reminders to the clients who are behind, without anyone working through the list by hand.
Create the March fee invoices for our retainer clients.
The question the client calls about
Answer while the client is still on the phone, with figures from their own books, instead of promising to come back after lunch.
How is Bygg & Co doing against the same period last year?
Reconciliation and year-end
Work through accounts, periods and vouchers, compare against last year and pull SIE files for the year-end clients without exporting company by company.
Export the SIE file for 2025 for my year-end clients.
New hires get further on their own
Someone new at the bureau finds the right answer without interrupting a colleague every time. Senior hours go to advice rather than supervision, and one sick day does not stall a client list.
ChatGPT Connector
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!
ChatGPT Connector
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.
// for_bureaus
Built for how a bureau actually works.
The same people inside many clients' Fortnox, a client list that keeps growing, and staff who join and leave. That is the everyday this is built for.
The licence follows the consultant, not the client company
One seat covers the consultant's entire client list. The next client costs nothing extra in licence, so the cost grows with the bureau rather than with the client list.
The whole client list in one question
Ask a question that spans the whole client list and get one answer. Comparisons cover up to twelve client companies per question.
A new client connected in minutes
Activate the free app in the client's Fortnox, sign in and link the company. No API keys to handle and nothing to install.
The consultant's Fortnox permissions apply
No second permission model to administer. A consultant can only do what the client has already granted permission for in Fortnox, and the changes show up at the client as usual.
Offboarding in one step
Remove a consultant and the client links and AI connections are revoked immediately. The seat can go to the next person.
Every consultant picks their own AI
The licence follows the consultant, not the AI app. One works in Claude, another in ChatGPT or Copilot, on the same agreement.
A setup done with you, and a named contact
We connect the companies together with you and show the way of working to the consultants. After that you have a named contact here who knows your setup, not a queue.
// pricing
Two prices, the same way of working.
Choose one licence per consultant, or one per consultant and company. The product is the same in both; what differs is the agreement.
One licence per user and company
Activated in each client company you work in.
99 kr per user and company / month
30-day money-back guarantee.
- No Fortnox integration licence needed
- Agreement and invoice stay with Fortnox
Prices exclude VAT. The more client companies each consultant works in, the sooner a seat that follows the consultant pays off. If the client companies already hold an integration licence, which many bureau clients do since it covers an unlimited number of integrations, it tips over sooner still. We do the maths on you work out both routes, and say plainly if the Claude Connector or the ChatGPT Connector is enough for you.

// security
Your clients' bookkeeping stays in Fortnox. Full stop.
You answer to the client for how their data is handled. This is built so you can answer that question without reservations.
Fortnox OAuth per user and client company
You sign in to every client company with your own Fortnox user. No passwords are stored at Sidcom, and sign-in tokens are encrypted.
The client's permissions set the limit
The AI can never do more than your Fortnox user is allowed to do in that company. Changes show up in the client's Fortnox as usual.
You have the last word
The AI proposes, and the AI app asks for your approval before a write is sent to Fortnox.
Nothing stored, everything passes through
The client's accounting data passes through while a question runs and is not stored at Sidcom.
Deletion without residue
Disconnect a client company, or remove a consultant, and access ends immediately and stored sign-in tokens are deleted.
Swedish vendor, built for GDPR
Sidcom is a Swedish company. A data processing agreement is available and sent on request.
Questions, answered.
What does it cost?
249 kr per user and month, excluding VAT. One seat covers every client company the consultant works in, so the next client costs nothing extra in licence. On top of that comes the Fortnox integration licence for the client companies that lack one. We help you work out both parts.
Does one seat really cover all the client companies?
Yes. The licence follows the consultant, who links their own client companies to the same connector. Each client company needs a Fortnox integration licence, and many already have one.
How does an accounting firm work with it?
Each consultant gets a seat and links their client companies, signing in with their own Fortnox user per company. Permissions and traceability follow that Fortnox user at each client, exactly as when working directly in Fortnox.
Does every client company need a Fortnox integration licence?
Yes, for this connector. Many client companies already have one, since it covers an unlimited number of integrations. The Claude Connector and the ChatGPT Connector need none, because they are bought and billed in Fortnox. We go through which of your client companies lack the licence, and if one of those connectors is cheaper for you, we say so.
How is it different from the Claude and ChatGPT Connectors?
The Claude Connector and the ChatGPT Connector you buy yourself in Fortnox and pay for per user and company, on your ordinary Fortnox invoice and with no integration licence. This one is built for the bureau: the licence follows the consultant across the whole client list, questions run across the client companies, we build the setup together with you and you get a named contact here. What the AI can reach is the same.
Which AI clients does it work with?
Any client that speaks MCP: Claude, ChatGPT, Microsoft Copilot and others. The licence is independent of the client, so one consultant can work in Claude and another in Copilot on the same agreement.
Can the AI compare several client companies?
Yes. Ask a question across the client companies you have linked, for example which of them have overdue supplier invoices, and get one answer. Comparisons cover up to 12 companies per question.
Which Fortnox modules are supported?
In practice everything the Fortnox API opens up: bookkeeping, customer invoices, orders, quotes, articles, inventory, supplier invoices, payments, payroll, time, asset register, projects, cost centres, archive, SIE export and more. See the full module table, 22 modules with exactly what you can do in each. What you personally reach is governed by your licences and permissions in Fortnox.
What happens when someone leaves the bureau?
Your administrator removes the person under Members. Their client links and AI connections are revoked immediately, and the seat can be assigned to someone else.
Is the clients' data safe?
The bookkeeping stays in Fortnox. Data passes through while a question runs and is not stored at Sidcom. Fortnox sign-in tokens are encrypted, no passwords are stored, and a data processing agreement is available on request.
We already have licences for the Claude or ChatGPT connector. Should we switch?
Keep them if they work. The Claude Connector and the ChatGPT Connector cover several companies too, with one licence per user and company, and they need no integration licence, since Fortnox bills them. Count the client companies per consultant: that is where a seat that follows the consultant tends to pay off. Get in touch and we will do the maths together and say plainly if you already have the right connector.
Does it suit a corporate group as well?
Yes. The setup is the same when the same people work across many companies inside a group, and questions across the companies work the same way. Get in touch and we will look at your companies and your routines.
Will there be a meeting?
Sometimes, and often email is enough. We read what you wrote, do the maths and come back with a proposal for the setup and what it costs. If we need to see how you work, we suggest half an hour, where we go through your client companies, your routines and what you need in terms of support and agreements.
How is it billed?
Agreement and invoice directly with Sidcom, per user and month. The Fortnox integration licence is billed separately by Fortnox, on the client company that needs it.
Connector not working?
Check that the free app is activated in the Fortnox App Market for the client company, and that the consultant has an assigned seat. The fastest check is to ask the assistant for the licence status. It can read the organisation's status and seats even when everything else is blocked.
Get in touch.
Tell us how the bureau works, how many consultants and client companies are involved and which AI you use. We come back with a proposal and the maths, and say plainly if the Claude Connector or the ChatGPT Connector would do instead.
