What is Record Deduplication?
Record Deduplication is The process of finding and merging duplicate records in your CRM or database.
Definition
Deduplication identifies records that represent the same person or company and merges them into a single source of truth. Duplicates creep in through multiple channels: web forms creating new records for existing contacts, list imports with slight name variations, sales reps entering records manually without checking. The average CRM has 10-30% duplicate records. Dedup tools use fuzzy matching on names, email domains, phone numbers, and company names to catch variations like 'Mike Smith' vs 'Michael Smith' or 'IBM' vs 'International Business Machines'.
Why It Matters
Duplicates corrupt everything downstream. Sales reps contact the same person twice from different records. Lead scores split across duplicates, so hot leads look lukewarm. Pipeline reports double-count opportunities. And marketing sends the same email twice to the same inbox, which tanks deliverability. Every percentage point of duplicates you eliminate compounds through your entire revenue operation.
Example
After importing 10,000 records from a trade show, an ops team runs DemandTools dedup and finds 1,800 matches against existing Salesforce records. They merge on a 'most recently updated' rule, preserving the newest email and phone while keeping the oldest created date for attribution accuracy.
