Keeping CRM data clean when you export thousands of contacts a month
Deduplication, field mapping, and ownership rules that stop a growing database from becoming unusable.

Every export is a chance to introduce duplicates. Decide the matching key before your first import, not after your tenth.
Map fields once and store the mapping. Ad-hoc mapping is the single largest source of unreportable CRM data.
Assign ownership at import time. Unowned records decay quietly and inflate your pipeline math.
Audit quarterly with a fixed checklist. Ten minutes of maintenance beats a migration project.
