What you're buying: authorized-user status on a real account
A tradeline adds you as an authorized user on an established revolving credit account. We don't promise a specific score outcome — nobody honestly can — but the purchase itself is backed by real terms, in writing:
- A full refund or an exchange, your choice, if a tradeline doesn't post to two credit bureaus by the end of its Reporting Period
- Credit sponsors are expected to keep balances at 15% or less of their limit while you're an authorized user
