CRM import mistakes that cost real money

Bulk imports are where most CRM disasters happen. The rep is sitting in front of a CSV, the import button is right there, what could go wrong. A lot.

The most expensive mistakes:

• Importing without a backup. First rule. Take a full export before any large import.
• Wrong owner field. All 5,000 leads dropped on one rep — they get to clean up. Or worse, on no one — they vanish from views.
• Wrong pipeline stage. All imported as "Won" or "New" — completely breaks reporting for that month.
• Lost opt-out status. Importing emails of people who already unsubscribed. Now your list re-mails them, generating spam complaints. CAN-SPAM, GDPR, CASL — actual fines.
• Duplicates from imperfect dedup. Phone "+15555551234" doesn't match "(555) 555-1234". Now you have two records.
• Encoding problems. Smart quotes, accented characters, emoji in CSV — break in some CRMs.
• Mapping fields wrong. Last name goes in first name. Discovered weeks later in mass email "Dear Smith".

Process that works:

• Backup first. Always.
• Test with 10-20 rows. Verify the result. Then 1,000. Verify. Then full set.
• Use system test/sandbox if available.
• Check opt-out matching against existing data before import.
• Have a rollback plan — knowing how to delete the just-imported records by import ID is critical.
