CRM Data Quality Checklist

A practical checklist for auditing and maintaining CRM data quality — completeness, consistency, duplicates, validity, and the boundary controls that keep it clean.

Use this checklist to audit a CRM today and to keep it clean going forward. Each item maps to something you can measure or enforce — nothing vague.

Completeness

  • Required fields (name, email, company) are populated on every record.
  • Empty-string and whitespace-only values are treated as missing, not present.
  • You've profiled completeness with the data-quality endpoint, not eyeballed it.

Consistency

  • Company names follow one canonical form (no Acme / Acme Inc / ACME split).
  • Phone numbers are stored in a single format (E.164).
  • Dates use one format across all records.
  • Emails are lowercased and trimmed.

Duplicates

  • Near-duplicates (not just exact) are detected with fuzzy matching.
  • A confidence threshold governs auto-merge vs. human review.
  • Survivorship rules decide which value wins per field.
  • New records are matched against existing ones at write time.

Validity

  • Email and phone formats are validated before records are written.
  • A validation boundary (Guard) rejects malformed inbound records with a reason.
  • Failed records go somewhere reviewable, not silently dropped.

Maintenance

  • Data quality is re-profiled on a schedule to catch drift.
  • Cleanups are previewed with dry_run before they run.
  • Every automated change is auditable after the fact.

Turn the checklist into enforcement: profile with /api/v1/data-quality, clean with /api/v1/repair, and guard the boundary with /api/v1/guard.
