Credits and billing
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

Plan credits vs purchased credits
Tandem plan credits come monthly and expire; purchased credits never do. Plan credits go first, and job ads use only purchased ones.
