Why Do Two Data Sources Disagree About the Same Customer?

A CRM, billing system, and analytics platform may each represent a customer differently. One may track a person, another a company account, and another a billing profile, so matching names do not guarantee matching records.

What to check

Compare the entity definition, stable identifiers, merge history, date of last sync, and transformation rules. Trace a few known examples through each system and identify whether records are duplicated, missing, or associated with different owners.

Recommended next step

Agree on a shared identity rule and document exceptions such as subsidiaries or household accounts. Add reconciliation checks and assign ownership for resolving conflicts rather than silently choosing one source.
