PolyAccounts

Built to be your accounting system of record

Build your business around durable books. Give people and software a shared financial foundation.

01

True general ledger

A double-entry general ledger with account hierarchies, split transactions, and retained financial history.

02

Live drillable reports

P&L, Balance Sheet, Cash Flow, Trial Balance, and Payees. Every amount is clickable and drills into the underlying entries.

03

Tools your agents can discover

Discoverable MCP tools for reading and writing records, running accounting workflows, and tracing every change.

04

Review before you post

Bring in bank transactions, inspect coding and duplicates, then post reviewed entries to the ledger.

Start small. Build with intelligence.

For founders, the agents that help them, and the accountants who keep the picture clear.

New companies

Set up a chart of accounts, bring in your first transactions, and see where the business stands.

AI agents and builders

Read, create, and update accounting records through MCP. Build workflows on exact ledger amounts and traceable actions.

Accountants and teams

Work from the same ledger, inspect every report, and review the decisions that change the books.

MCP

The books your agents can run.

Give AI agents full accounting access. Let them create entries, update records, post invoices, record payments, reconcile accounts, and manage periods in the same system your team uses.

Explore agent tools

One company per connection

Each credential belongs to one company. Administrators can revoke it, and access ends when the administrator loses permission.

Exact amounts, visible limits

Core accounting tools return decimal strings, explicit currency, date bounds, and pagination or truncation information.

Actions you can trace

Writes have durable receipts and stable retry keys. Edits check the current record revision, and deletions retain accounting history.

Give your next company a lasting financial home

Start with your books. Bring your accountant. Connect your agents when you are ready.
