Lead Hacker is prepaid. This is by design.
When you start a campaign, you're pre-purchasing a set number of leads. Think of it like loading credit onto a gift card. The balance is there. Leads are delivered as they're identified.
Why prepaid works:
No surprise bills at the end of the month
You control your spend upfront
If a campaign underperforms, repurpose it (not refunded, but redirected)
If your campaign isn't generating leads, check your keywords using the Volume Estimator. Low volume keywords = low leads, regardless of your budget.
