When Customers Are Billed

If your product has a one-time charge, a monthly charge, or both, your customers are immediately billed when they sign up for your product. The charge includes the one-time charge and the first monthly charge. The monthly charge is prorated based on when the customer signs up during the month. For an example, see Sign-Up Payments.

Customers are also billed on the first day of each month for:

  • The previous month's usage of all Amazon DevPay products they use (for the products that have usage-based charges)

  • The monthly charge for the current month (for the products that have a monthly charge)

For an example, see Monthly Payments.

They receive a monthly Amazon Payments billing e-mail showing the total amount they have been charged for all the DevPay products (for more information, see the e-mail template at When the Customer Is Billed Each Month). They can see more details about their usage on their Application Billing page ( The Amazon Payments bill doesn't show the name of any underlying AWS service that your DevPay product uses. Only your product's name is displayed.


For customers who are also AWS developers (who use AWS products such as Amazon EC2 or Amazon S3), this Amazon Payments bill is separate from their AWS developer bill. If the customer uses Amazon EC2 elastic IP addresses, Amazon Elastic Block Store (Amazon EBS), Auto Scaling, of Amazon CloudWatch with your paid AMI, any charges for those are part of the customer's AWS developer bill. For more information, see Costs You're Not Responsible For.
