Prepaid Vs Postpaid Ad Spend For Agencies
In short: Prepaid ad spend means the client funds the budget before ads run. Postpaid means the agency or provider pays first and gets repaid later. Prepaid is safer for the agency because you never carry unfunded spend. Postpaid can feel easier to sell, but the agency owns the risk if a client pays late or disappears.
What prepaid and postpaid actually mean
With prepaid, the client sends money first and the ad budget is loaded from it. With postpaid, ads run on credit and an invoice follows. The difference is simple: who is out of pocket if something goes wrong.
How they compare for an agency
- Cash risk. Prepaid keeps it with the client. Postpaid puts it on you until the invoice is paid.
- Cash flow. Prepaid never ties up your money. Postpaid can, especially when several clients scale at once.
- Client experience. Postpaid feels flexible to the client. Prepaid needs a clear explanation, but most clients accept it when it is presented as the standard way you work.
- Account stability. Unpaid balances and declined payments can pause campaigns. Funded budgets avoid that.
