Starting today, customers can create proforma pricing rules to control the application of free tier offers for specific AWS services in AWS Billing Conductor (ABC). Using service-scoped free tier pricing rules, customers can model a proforma chargeback workflow that only shares their always free tier benefits with a targeted set of accounts, those within a specific billing group. For example, a customer can choose to isolate their always free tier offer for AWS Step Functions (4,000 state transitions per month) to a “sandbox” billing group meant for experimentation, simplifying customers’ free tier chargeback model for specific accounts throughout the month.
