Advertising is prepaid. Advertisers fund a balance, and campaign spend draws it down.
The flow
- An advertiser adds funds (in My Account, Billing -> Add Funds, or on your branded platform).
- Campaigns spend against that balance as they deliver.
- When the balance reaches zero, delivery stops immediately - even though campaigns still read as active.
This is the most common cause of a campaign stopping without warning. See An advertiser reports no delivery (for operators).
Separate from your platform fee
Advertiser balances have nothing to do with what you pay AdTech Europe for the platform. The platform fee rents, licenses or buys the technology; balances buy media.
Does unused balance expire?
- On your own white label platform your advertisers pay you, so balance and refund rules are yours to set.
- On accounts held directly with AdTech Europe, unused advertising credit expires 12 months after it was added, and can be refunded on request minus processing fees and any bonus credit. See the Refund Policy.
Visibility
Balances, transaction and funding records, payment notifications and invoice history are all available, and administrators can see the position across all advertisers rather than one account at a time.
