AWS Cross-Account Cost Monitoring

Managing AWS costs across multiple accounts can be a challenge—especially when budgets have to span different teams, workloads, or business units. Traditionally, this often meant relying on management account access, which can introduce security and governance concerns.

Now, AWS has made things simpler. The latest AWS Budgets update introduces Billing View support, enabling you to set up cross-account budgets without needing management account access. This is a big win for organizations looking to monitor and control AWS spend more securely and efficiently.

What’s New in AWS Budgets with Billing View?

With this update, you can:

• Create and manage budgets for multiple AWS accounts straight from Billing View.
• Use Cost Allocation Tags or specific account IDs to filter your budget data.
• Track application-level budgets even if workloads span several accounts.
• Set up organization-wide budgets without compromising security.

Why This Matters for AWS Cost Management

In modern multi-account AWS environments, costs are often distributed across different teams and services. This separation is great for operational clarity, but it can make cost tracking fragmented.

Previously, budget creation often required:

1.Centralized monitoring via the management account,

or

2.Manual data exports and merges from multiple accounts.

With Billing View support, AWS Budgets can now pull filtered data directly from views—no central account juggling required.

Practical Use Cases

1.Engineering Teams

Create a single budget filtered by tags (e.g., App: MyProduct) to monitor total spend across all related accounts.

2.FinOps Teams

Build organization-wide budgets using unfiltered Billing Views for a complete cost overview—no management account needed.

3.Project Managers

Set up temporary project budgets (e.g., Project: Migration2025) that consolidate costs from multiple accounts into one view.

Security & Governance Benefits

• Least Privilege Access – Avoid giving unnecessary management account permissions.
• Better Separation of Duties – Finance, engineering, and operations teams can manage their own budgets.
• Improved Compliance – Minimize security risks while retaining cost visibility.
