Plug in your AI. Octobooks keeps the books. You approve what leaves the company, and get back to building.
Accounting in 2025 becomes Accounting in 2027. Welcome to the future. Let's go.
How it works
Add Octobooks to Claude Cowork or any other MCP client. Built your own AI? The REST API with webhooks is ready for it.
It brings the opening figures and the documents and answers Octobooks' questions. You add the bank statements. Coming from another system? Bring the books as they are.
Octobooks reads, matches and books by fixed rules, and asks your AI when it needs an answer. You get a tap on the shoulder when something is about to leave the company. It has the arms for it.
Bank statements come in as a file you upload. The direct bank connection is next up.
You stay in control
Look, press approve, confirm with your authenticator code. Done.
Approve a rule once, with a cap. Everything that fits goes straight through; the rest comes to you.
A second, independent agent checks the first. When they agree, it goes through; when they differ, you decide.
Type a one time code into the chat with your AI and it is approved. Switch it on when you want it.
Your AI shares the category and keeps your private context to itself. When Octobooks asks what a taxi was for, the answer is "Travel". Your calendar and who you met stay with you: the answer has no field for them.
Countries
Octobooks hands you the figures and the files in the layout the tax office expects, ready to go. Direct filing is on its way, country by country; until then you or your accountant press send.
Security and your data
Your books live on servers at Hetzner in Germany. Backups are encrypted.
What is posted stays posted. A correction is a reversal, so the trail is always complete. Every entry and document carries a fingerprint, checked every night.
The books are yours. Agents ask, and what goes through is what you gave a mandate for.
Take everything with you in one archive: entries, documents and their links. DATEV and spreadsheet exports included.
What a document says is data, never an instruction. A supplier cannot talk your AI into a booking through the text of an invoice.

Questions
Yes. Early access is open and free. Get in touch through the form below and we set you up. Octobooks already runs every day on the books of two real trading companies, a UK Ltd and a German GmbH, in a parallel run next to their accountant.
You do, or your accountant, with everything ready: Octobooks hands over the figures and, for Germany and Austria, the draft files in the layout the tax office expects. Direct filing from Octobooks is next up, country by country, and each filing will wait for your approval.
Claude Cowork, and any other client that speaks the Model Context Protocol (MCP). Built your own AI? It uses the REST API. Bring whichever model you like: Octobooks works with all of them.
You set the rules, once, on your own page: you decide yourself, your AI decides for bookings that stay inside the books, two agents agree, or a rule you approved covers it. Anything that leaves the company waits for you. Everything decided without you shows up on a daily list and can be reversed.
The category, and that is all. When a bank line needs an answer, Octobooks offers categories from your chart of accounts and your AI picks one. Reasons, notes and your calendar stay with you: there is no field for them.
Octobooks does the bookkeeping. Advice stays with a human adviser, and many owners keep one for the year end and the judgement calls. Yours gets a read only seat and the exports they already know, such as DATEV.
Yes, and it is easy. Xero, QuickBooks, FreeAgent, Sage, DATEV, sevDesk, Lexware Office or a spreadsheet: your AI and Octobooks move the books over, and we check every balance with you. Mid month, half booked, your accountant dropped the pen? No problem. We start from where you are.
You take it with you: one archive with every entry, every document and the links between them, checkable without Octobooks.
