+## Cost
+You will be billed for the [various services](docs/services.md) leveraged by AWS SaaS Boost. Provisioned resources are tagged with "SaaS Boost" and each tenant's resources are also uniquely tagged to help you with [cost allocation](https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/cost-alloc-tags.html).
+
+Each tenant you onboard into an AWS SaaS Boost environment will provision more infrastructure and will increase your costs.
+
+Note that the _optional_ Analytics and Metrics module will provision a Redshift cluster.
