# Can I Test Archera in an AWS Sub-Account?

Yes — you can add Archera's Trial IAM Read-Only credential to any AWS sub-account that has at minimum access to Cost Explorer, and optionally with the ability to generate a Cost & Usage Report.

## Full Platform Access

This will enable you to access the full Archera platform; however, much of the data around commitment coverage, savings, and net spend will be incorrect until you install Archera's Trial IAM Read-Only credential to the **master account** in that organization.

## Exception: Fully Functional Sub-Account Only Install

The only exception that would allow a sub-account-only install to be fully functional is if:

* The sub-account is responsible for its own RI & SP purchasing
* It is not part of an EDP/PPA organization
* AWS organization discount sharing is turned off

## What You Can Test with Sub-Account Only

* Scenario analysis
* Cost visibility & alerting
* Right-sizing planning
* Preview of commitment purchasing & renewal tools

## Limitations

You will **not** be able to move forward with:

* Commitment automation
* Custom cost reporting
* Guaranteed Reserved Instances
