# Concepts

## Docs

- [How Runledger fits together](https://docs.runledger.co/concepts/overview.md): What you configure, what your code calls, what Runledger records, and which page explains each part.
- [Outcome settlement](https://docs.runledger.co/concepts/outcome-settlement.md): The life of an outcome charge, and the rules that decide whether it stands.
- [Checks and holds](https://docs.runledger.co/concepts/checks-and-holds.md): Decide before work starts, and reserve what it will cost.
- [Prepaid and postpaid billing](https://docs.runledger.co/concepts/billing.md): Plans, balances, invoices and the ledger behind them.
- [Payment providers](https://docs.runledger.co/concepts/payment-providers.md): Several providers at once, the rules that choose between them, and what stays at the provider.
- [Pricing from cost](https://docs.runledger.co/concepts/cost-reflective-pricing.md): Price AI products from what each call costs, starting from provider prices Runledger keeps current, and stop work that would sell below your margin.
