# How Long Does It Take for Changes to My AWS Resources to Reflect in Archera?

We rely on the AWS Cost and Usage & Cost Explorer APIs to refresh the resource list on a daily basis, as this is the source of truth from Amazon for what gets billed.

Due to the way AWS reports this data it has a **24 hour lag** and can take one day for any changes to be reflected in the platform, as outlined in their [official documents](https://docs.aws.amazon.com/cost-management/latest/userguide/ce-what-is.html).
