# Ledger

> Every credit movement is recorded so balances stay auditable and trustworthy.

Jaza records credit movements so you can trust balances and reconcile activity. Top-ups and consumes produce ledger history you can inspect in the dashboard (credit activity).

## What gets recorded

Typical movements include:

| Kind            | Description                              |
| --------------- | ---------------------------------------- |
| Top-up / credit | Credits added after a successful payment |
| Consume / debit | Credits deducted for a feature or amount |

Each consume should carry an **idempotency key** from your backend so retries do not double-charge.

## Why it matters

* Trace a balance back to purchases and feature usage.
* Safe retries with idempotency.
* Dashboard analytics and credit activity stay consistent with what the SDKs report.
