You can pool usage across multiple services within the same plan to determine the rate to be used for billing a customer. The customer will be billed for usage based on the total usage pool for all of the services on a plan, instead of the number of billable units for each service. The total usage pool will be reset to 0 after each invoice is generated for a customer unless you have usage accumulation enabled for the customer.
Refer to the usage pooling example to see how invoice charges are calculated for a service with usage pooling enabled.
Once a customer has been billed for usage on a plan, you cannot enable or disable usage pooling for that plan. Usage pooling applies to only standard tier structures, not volume or flat rate tier structures.
Usage pooling will work whether Aria rates usage at time of invoicing or when usage records are uploaded into the system (real-time). If you load usage records into Aria with currency amounts assigned to them, your customers will be billed based on your specified currency amounts, even if you have usage pooling enabled for those customers.
