You can adjust pricing rates either globally, by billing entity, by individual service, or SKU within a service if needed. You will be able to create pricing plans, which are a collection of pricing rules that you can assign to one or to multiple billing groups in a billing period. Each billing group can have its own pricing plan, as needed. Global rules apply to all usage in a billing group. Billing entity rules (such as AWS Marketplace) only apply to charges that match that billing entity. Service-specific rates apply to a specific service consumed in the billing group. SKU pricing rules apply to the unique combination of usage type and operation, within a selected service.
