│ • Similar to: AWS Enterprise Discount Program │
│ │
│ Hierarchy: │
│ Billing Account → Departments → Enrollment Accounts → Subscriptions │
│ │
└────────────────────────────────────────────────────────────────────────────┘
MICROSOFT CUSTOMER AGREEMENT (MCA):
┌────────────────────────────────────────────────────────────────────────────┐
│ │
│ • Modern billing for direct customers │
│ • No upfront commitment required │
│ • Billing profiles and invoice sections │
│ • Similar to: AWS regular accounts │
│ │

COST MANAGEMENT SCOPES:
───────────────────────
You can view costs at different levels:
┌─────────────────────────────────────────────────────────────────────────────┐
│ │
│ SCOPE ACCESS NEEDED USE CASE │
│ ───── ───────────── ──────── │
│ │
│ Billing Account Billing Admin Total enterprise spend │
│ (EA/MCA) across all subs │

│ │
│ Individual Resource Reader on resource Specific service cost │
│ │
└─────────────────────────────────────────────────────────────────────────────┘
AWS COMPARISON:
• AWS Cost Explorer also supports account-level filtering
• Azure Management Groups = AWS Organizations OUs
• Azure provides native multi-cloud cost visibility (AWS, GCP)
