Which permission allows IAM users to view billing pages in the AWS console?

The permission that allows IAM users to view billing pages in the AWS console is indeed "ViewBilling." This permission is specifically granted to IAM users to enable them to access various billing-related information and dashboards within the AWS Management Console. When IAM users are assigned this permission, they can view their account's usage and costs, enabling better financial tracking and management of AWS services.

This capability is fundamental for organizations that require certain personnel to monitor costs without granting full administrative privileges. By assigning "ViewBilling," users can obtain detailed cost breakdowns, billing history, and usage reports, which are essential for budgeting and financial assessments.

The other options do not align with this specific functionality. For instance, "BillingAccess" might sound like a valid permission but does not exist as a predefined permission in IAM roles. Similarly, "AccountView" and "CostManagement" may refer to broader finance-related functions but do not pertain specifically to the viewing of billing pages, which is limited to the "ViewBilling" permission.
