Trust-first reconciliation

A vendor statement balance you can actually trust.

Connect your ledger via API or MCP, send your supplier statements, and get back a math-verified closing balance for every account — or an honest flag where it can’t be proven. Any ERP. No integration to build. No guessing.

Connects to your accounting system via MCP or API

Sage · MYOB · TechOne · or any ERP — via its MCP, its API, or one built for it

Math-verified, never guessed

We only sign a closing balance when the lines provably add up to it. If they don't, we flag it for review — we never hand you a confident-but-wrong number.

Any ERP, no integration to build

Your AI assistant pulls your ledger straight from your accounting system over its MCP or API — Xero, QuickBooks, Vista and more. A short setup video per ERP shows you how. No connector to build, nothing to install.

Pay only for proof

You're billed for a verified statement and nothing else. Every abstain, low-confidence result, and failure is free — always.

The difference

Most AI guesses. We refuse to.

Other tools hand you a confident answer whether or not it’s right — and a wrong balance you trust is worse than no answer at all. Statement Zen works the other way around: the model proposes, the maths disposes. A closing balance is only ever signed when the line items provably reconcile to it. When they don’t, you get an honest flag with the reason — not a number we made up. That’s how you get a result you can post without re-checking.

How it works

Three steps. Nothing to install.

Your AI assistant does the wiring. You just send the statement.

Connect your ledger

Point your AI assistant — Claude, Gemini, ChatGPT or Grok — at your ERP's MCP and ours. It pulls your AP ledger; a 3-minute video per ERP walks you through the setup. No connector to build.

Send the statement

Upload or email the vendor statement PDF (or pass it through the API). We read every line and reconcile it against your ledger — totals, credits, ageing and all.

Signed, or honestly flagged

A math-verified closing balance you can post straight away — or an honest “needs review” with the reason. Never a number we can't stand behind.

For developers & AI assistants

Reconcile from your AI assistant

Point Claude, Gemini, ChatGPT or Grok at our MCP server and your ERP’s MCP — like Xero’s. Your assistant pulls the ledger, sends the statement, and gets back a signed balance with the trust-first guarantee baked in. Prefer raw HTTP? One REST call does the same. Follow the short setup video for your ERP and you’re reconciling in minutes.

Works with your ERP’s MCP or API — and if it doesn’t have one, anyone can build a small MCP that feeds ours.
A verified flag on every result — your code (or your assistant) knows when to trust it.
Metered on proof: abstains and failures never cost a credit.

Why trust this

Built by someone who did this by hand for a decade

Statement Zen isn’t a whiteboard startup idea. It’s the productised version of the last and ugliest system I automated across twelve years embedded inside two Australian groups, each with around 200 active vendors. Vendor statement reconciliation was the one process that refused to die — two full weeks every month, chasing duplicates, missing credits, and statements that wouldn’t balance. We got it down to half a day. This is that engine, packaged — built the way a CFO would want it, with trust as the floor.
