# Adjustments

Adjustment entities describe a post-billing adjustment to a billed or completed transaction.

---

Billed transactions are considered financial records for tax and legal purposes, so they can't be changed. Adjustments let you record actions that impact revenue for a transaction after it's been billed.

You can create adjustments for billed or completed transactions to refund or credit all or part of a transaction.

Most refunds for live accounts must be approved by Paddle, but [some are automatically approved](https://developer.paddle.com/build/transactions/create-transaction-adjustments#background-refunds.md). For sandbox accounts, Paddle automatically approves all refunds every ten minutes.

Where customers raise a chargeback with their payment method issuer, Paddle automatically creates an adjustment to refund the disputed amount.

Adjustment entities hold information like:

- What kind of adjustment it is.
- Why the adjustment was created.
- Which transaction and items an adjustment is for.
- Calculated totals for an adjustment.

Adjustments work with [transactions](https://developer.paddle.com/api-reference/transactions.md), [subscriptions](https://developer.paddle.com/api-reference/subscriptions.md), and [customers](https://developer.paddle.com/api-reference/customers.md).

Adjustments are financial records. They can't be deleted or changed once they've been created. [Contact Paddle](mailto:sellers@paddle.com) if you need help with an adjustment.
