Who it's for · everyone paid through Stripe

# Books that show their work, whoever pays you.

Every payment through Stripe becomes balanced books and a signed receipt anyone can check, and every month can be sealed. The same engine and the same proof, for every organization. What changes is the words, not the checks.

The same proof

Same engine, same proof. Every vertical is a seeded scenario, and its KPI hashes match across the engine, hledger and DuckDB.

Every organization named on this site is invented, and its data is synthetic. [See every simulated preset](https://tfd-ledger.pages.dev/proof#simulations).
