Everything you sell on and work with,
already in the books
OneBooks connects to your point of sale, the AI assistants you use, the tax authorities you file with and the systems you're moving from — so revenue, tax and history land in the ledger without anyone re-typing them.
Sales post themselves.
Connect the till and the books are ready when the shift ends — tender by tender, tax included, duplicate-proof.
Your books, readable by the AI you already use.
OneBooks speaks the Model Context Protocol. Connect once over OAuth; the AI reads real reports and prepares documents you confirm.
Bring your history along.
Switching systems shouldn't mean starting from zero. Pull your ledgers, balances and vouchers in — reviewed before anything posts.
File where your authority expects.
Compliance is built into the document, not bolted onto the report — so the filing is the easy part.
Apps that work inside OneBooks.
Add reviewed apps from other developers. You see exactly what each one can access before you install it, and you can uninstall it any time.
Build on OneBooks.
An OAuth 2.0 API and MCP, apps that run inside OneBooks, free sandbox businesses — and a marketplace to publish to.
Build it, or let's build it together.
An OAuth 2.0 API and MCP, apps that run inside OneBooks and a marketplace to list them in — all open to you. Start in the developer console, or talk to us about a partnership that gives your customers the OneBooks Standard plan at no cost.
Connect once. Stop re-typing forever.
Start free, connect your point of sale or your AI assistant, and watch the books write themselves.
