Adjust your monthly ad spend
If you'd like to change the monthly ad spend on an account - to be applied on the next re-bill date - you can Request a Spend Change.
If you would like to add budget to the account immediately, you can purchase a One-time Budget Add-on as shown below.
Add additional budget - one time
Purchasing a one-time budget add-on will increase the ad balance right away. This add-on will not be charged each month - it is a one-time transaction.
