# Billing

Use Billing to top up credit and review recent transactions. This section helps you confirm your current balance and track billing activity.

## Transaction History

Transaction History appears at the bottom of the Billing page and shows a detailed breakdown of your credit activity. Use it to review past transactions and track how credits are added and used over time. Chatlyst will also send a receipt to your email with downloadable links for both the [invoice and receipt](/chatlyst-user-guide/top-up-guideline/top-up-guideline.md#purchase-confirmation).&#x20;

{% hint style="info" %}
The credit transaction history is grouped by day.
