# Best Practice 20.4 – Establish cost-related procedures and controls
<a name="best-practice-20-4"></a>

 It might be necessary to adapt traditional cost assessment processes to be cloud ready. Gain familiarity with how to implement the right financial practices and policies by reviewing the [AWS Cloud Financial Management Guide](https://aws.amazon.com/executive-insights/content/cloud-financial-management-reference-guide). 

 **Suggestion 20.4.1 – Educate administrators on cost implications** 

Introduce mechanisms to assign accountability and provide incentives for cost optimization.

 **Suggestion 20.4.2 – Only allow certain users the ability to provision instances using IAM controls** 

Use IAM policies aligned with resource type and job function within account boundaries to ensure cost control. For example, you might allow additional small-scale systems in a sandbox account to be controlled within a project team but have an additional approval process and restricted access for larger instances in a production account.
