How to hide the margins/credits in the CID when creating dashboards the payer account

Have you looked at the AWS Billing Conductor service?

By default, adding accounts into a billing group will allow the Billing Conductor service to create a proforma view of the CUR for that billing group that defaults to on demand rates, but allows you to customize the rates if you choose. The primary accounts in the billing group would also see their proforma rates in the Bills page in the console.

The proforma CUR that is created for a billing group could then be used with the CID to give dashboards to the end customers. The Payer account will be able to create CURs for each billing group and then use that CUR to provide a dashboard. You can create billing groups with 1 or many accounts in it, but it does not allow you to split an account or set a billing group based on other criteria.

Pricing for this service is tiered based on how many accounts are in billing groups in a month, but starts at $8.25/mo for the first 500 accounts. It goes down after that.

Hello, In addition to AWS Billing Conductor you can directly use CID to showback. By default CID shows everything as is, but it is totally possible to modify queries, excluding Credits and Refunds or adding additional lines adding them to the default summary view.

Once you achieve the view that corresponds your business needs, you can set up Row Level Security to allow access to dashboards for the end customers.
