To run a campaign you need to either prepay (have account balance available) or have a payment method on file for billing.
Standard Payments
When you set up a campaign, you put a credit card on file for us to bill to. When you submit your campaign, we place an authorization hold for 1-7 days of expected spend on that card. A portion of this hold, equal to the actual spend, will be captured not more than 7 days after after the hold has been placed.
Prepayments
You can always prepay credit on your account. Blip will use the credit that you upload to run your ads.
Once the prepaid credit has been spent, you will continue to be billed as your ads run unless it is a political campaign. Political campaigns require prepayments to run.
How to stop spending
If you would like to stop spending, be sure to disable your campaigns.
