AWS Billing Conductor (ABC) now applies a tiered, account-based pricing model for all accounts assigned to an ABC billing group (effective June 1, 2023). The pricing change replaces prior ABC pricing, which relied on the volume of proforma billing records generated. The number of running resources in your account does not affect the new account-based pricing model. Along with the pricing model change, ABC’s free tier policy has also been updated as a free trial of 62 days (2 months), rather than the previous limit on usage records. For existing ABC customers, the new free tier policy takes effect on April 1, 2023. For new ABC customers, including those who’ve tried the service, but don’t have an active billing group as of April 1, 2023, the free tier trial begins when they add accounts to an ABC billing group.
