<section class="help-summary" aria-labelledby="in-short"><h2 id="in-short">In short</h2><p>A credit note reduces a receivable when an allocation links it to an invoice on the same customer account. Its available amount accounts for refunds and allocations already used. The credit note moves from **Issued** to **Partially settled**, then **Settled** when nothing remains. The invoice balance decreases in parallel and can become paid without another bank payment.</p></section>

## Expected result

Each allocation links the correct credit note and invoice, reducing both remaining amounts equally.

## Before you start

- Confirm invoice and credit note belong to the same account.
- Locate available credit and remaining invoice amount.

## Procedure

1. Open the credit note and check issued, refunded, allocated, and remaining amounts.
2. Choose the invoice on the same account that should receive the credit.
3. Enter a positive amount within both available limits.
4. Submit and verify the allocation on both credit note and invoice.
5. Review resulting statuses and the collection account balance.

## What Billabex does

Allocation is coordinated across both aggregates so invoice and credit note contain the same link. Removing it restores remaining amounts and can reactivate a receivable previously covered.

## If the result is not what you expected

- Allocation across different accounts is rejected.
- A refunded or consumed credit note cannot be fully reused.
- When a synchronized document changes, wait for orphan-allocation cleanup before retrying.
