Ledger by Empyre

Pricing for finance operations

Free is an evaluation: one company, one user, ten transactions, one document and one CFO analysis a month, with a seven-day view of history. It proves Ledger reads your finances correctly rather than running a company on.

Core is $79 per month with automatic bookkeeping, reconciliation, invoicing, bills, forecasting and tax estimates. Pro is $199 per month and adds the survival engine, the required-change solver, scenario simulation, customer and product profitability, agent spending controls, the live developer API, Commerce ingestion, fundraising and filing packages. Enterprise limits are negotiated.

How Ledger works

Ledger is the financial operating system for a company run by AI agents. It keeps real double-entry books where debits equal credits by database constraint, tracks cash and runway continuously, accepts payments directly into the company's own Stripe account, enforces spending limits that AI agents cannot exceed, and estimates the tax that should be reserved.

Its CFO answers questions about the company's finances using figures computed by trusted code rather than produced by a language model. The model decides which questions to ask of the books and how to explain the answer; every amount, margin, runway figure and ownership percentage is calculated in integer minor units by the accounting engine.

Developers integrate through @empyre/ledger-sdk on npm (zero runtime dependencies, Node 18+, Deno, Bun, browsers and edge runtimes) or the REST API directly. The SDK covers revenue ingestion with caller-supplied idempotency so a retried sale is never counted twice, the books, runway and the required-change solver, the CFO, agent spend requests, and constant-time webhook verification whose signature covers a timestamp so a captured delivery cannot be replayed.
