Why Choose Our AWS Billing Audit Service

Comprehensive billing analysis that uncovers hidden costs, identifies waste, and provides actionable cost reduction strategies.

📊

Cost Explorer Analysis

Deep analysis using AWS Cost Explorer to examine spending patterns across all services, regions, and accounts. We identify trends, seasonal variations, growth patterns, and cost anomalies that warrant investigation. Our analysis includes custom groupings by tag, account, service, and usage type.

🚨

Billing Anomaly Detection

Configure AWS Cost Anomaly Detection and analyze alerts to catch unexpected spending spikes. We investigate cost increases, identify root causes, determine if anomalies represent genuine business growth or wasteful spending, and establish thresholds that prevent future surprises.

🔍

Service-Level Breakdown

Detailed analysis of every AWS service in your bill. We examine EC2 instance hours, EBS storage volumes, S3 storage classes and requests, RDS instance types, Lambda invocations, data transfer costs, and support charges to identify services driving the highest costs.

🏷️

Tag-Based Cost Allocation

Analyze spending by cost allocation tags to understand which teams, projects, environments, or customers generate the most costs. We identify untagged resources, establish tagging standards, implement tag enforcement policies, and create custom cost reports for financial accountability.

💰

Budget Alerts and Forecasting

Review existing AWS Budgets or implement new budget alerts that notify stakeholders before overspending occurs. We configure forecasted budget alerts, actual spend thresholds, and custom budget dimensions. Our forecasting models predict future costs based on historical trends and planned growth.

📋

Recommendations Report

Comprehensive report with prioritized cost reduction opportunities. Each recommendation includes current cost, potential savings, implementation effort, risk assessment, and step-by-step execution instructions. We categorize recommendations by quick wins, strategic optimizations, and architectural improvements.

Frequently Asked Questions

How long does a billing audit take?

A standard billing audit takes 3-5 business days depending on account complexity. We analyze your Cost and Usage Reports, examine multiple months of billing data, identify anomalies, and compile detailed recommendations. Enterprise multi-account audits may require 1-2 weeks for comprehensive analysis.

What access do you need to perform an audit?

We require read-only IAM access with permissions for Cost Explorer, Billing Console, AWS Organizations, and resource tagging. We use AWS-managed policies like ViewOnlyAccess and Billing. We never require write permissions for audit engagements and follow security best practices with MFA and temporary credentials.

What deliverables do I receive?

You receive a comprehensive audit report including executive summary, detailed spending analysis by service and tag, cost trend visualizations, anomaly analysis, RI and Savings Plan utilization review, and prioritized recommendations with estimated savings, effort, and implementation steps.

Can you help implement the recommendations?

Yes. While the audit provides detailed implementation guidance, we offer follow-on engagements to execute recommendations. Our Professional and Enterprise plans include implementation support, or you can combine the audit with our AWS Cost Optimization service for end-to-end cost reduction.
