The Hidden Cost of Poor CDR Design

CDR structure design plays a bigger role in billing accuracy than most people realize.

Poorly designed CDRs often lead to:

• missing required fields for rating
• inconsistent data formats across vendors
• difficulty in reconciliation
• performance issues during processing
• inability to track session lifecycle properly

Once deployed, fixing CDR structure is extremely difficult because it affects every downstream system.

In many cases, billing issues are not processing problems—they are data design problems from the start.

Curious how others handle evolving CDR formats without breaking existing billing pipelines?
