# How sync credits work

> What a sync credit is and how usage is counted.

A **sync credit** represents one lead's tracking data being synced to your CRM. As iTracker360 detects new leads and syncs the tracking data to your CRM, each contact updated counts toward your plan's usage.

## What counts

- One contact synced with attribution = one credit.
- Free plans include a monthly allowance that resets at the start of each month.
- Paid plans raise or remove that limit — see the current plans on the billing page.

If you're approaching a limit on a free plan, upgrading keeps attribution flowing without interruption. Your current usage and allowance are always shown in **Billing**.
