CompounderDo the bookkeeping in ChatGPT. Or Claude. Or wherever you like.
Compounder makes your company's finances headless — so the AI can understand, analyse and, where the systems support it, post entries with the right data, rules and permissions.

Business Centraland moreYour AI becomes the workspace. Compounder becomes the finance layer.
Traditional finance work means jumping between the business system, reporting tools and spreadsheets. With Compounder the work starts in the AI you already use.
A monthly close, step by step.
“What needs to be done before the monthly close?”
The AI reads the period from Compounder and lists what remains: unposted supplier invoices, unreconciled accounts, missing accruals.
AI can do a lot. Compounder gives it the right financial context.
We are not building our own AI model. We give the one you already use access to correct, structured financial information.
The right data
Current, structured financial data from connected systems.
The right rules
Charts of accounts, definitions, accounting rules and the company's own instructions.
The right access
The AI only gets access to the companies and the information the user is permitted to see.
The right actions
Where the business system supports it, approved actions can be carried out back in the system.
…but don't build your finance work around one AI model.
Compounder is AI-headless. Pick the tool that suits you, switch when a better one arrives, and keep the same financial source of truth.
Claude today→ChatGPT tomorrow→A specialised agent next yearFrom voucher to board report. Without changing workspace.
Bookkeeping, control, analysis and reporting in the same conversation.
The bookkeeping is only the beginning.
When the AI already has the right financial context, the work continues without anything having to be set up again.
One company or a hundred clients.
The same layer works for the company running its own finances and for the firm working across many clients. Every client has its own companies, rules, data and permissions — and the AI can take the repetitive work.
The freedom from AI. The control from Compounder.
The work happens in the AI. The boundaries are set in Compounder and apply whichever tool is asking.
Per user, company and group. They follow along into every AI tool.
Chart of accounts, KPIs and accounting rules are decided once and apply to everyone.
Sensitive actions are only carried out once a human has approved them.
Who, which AI, which action, at which time.
Every figure traces back to source system and voucher.
The documentation behind every completed action is kept.
From financial documentation to bookkeeping, analysis and the next decision.
Compounder connects the accounting with the rest of the company's finances — and with the AI you already work in.
