# Reserved credits

> Reserved credits stay in your Tandem balance, set aside for a running job ad or an open AI interview invite until used or returned.

## What reserves credits

- **Job ads.** When you start advertising, Tandem reserves the full pack from your purchased credits. Credits are spent as the ad runs.
- **AI interview invites.** When Tandem sends an invite, it reserves the credits for that interview. They are spent only when the interview happens.

Until then, you can't spend reserved credits on anything else.

## When reserved credits come back

- **Job ads:** unspent credits return to your purchased credits when you stop advertising, close the role, or the ad's 30 days end.
- **AI interviews:** if the invite isn't used within 7 days, the reservation is released. The candidate shows in `Needs review` as `Invite expired`.

## Where to see them

In `Settings → Usage`, see `Reserved` on the `Credits` bar. The `Job ads` card shows what each ad reserved, spent and has unspent.
