CRM Data Cleansing & Deduplication Services
CRM data cleansing and deduplication services: standardization, normalization, fuzzy matching, address verification, email validation, and golden record creation pre or post-migration.
The Data Quality Problem in CRM
Industry research shows the average B2B CRM contains 25-30% duplicate records, 20% incomplete contact data, and 10-15% invalid email addresses. Bad data destroys CRM value: forecasts based on duplicates, marketing wasting spend on bounces, sales reps wasting time on incomplete records, and analytics that lie. Most CRM data quality problems are not solved by buying a “data quality tool”. they are solved by running a structured cleansing program.
Widelly’s data cleansing practice combines automated tooling (Demand Tools, RingLead, Cloudingo, Validity), data enrichment (ZoomInfo, Clearbit, Lusha, Cognism), and structured processes for data hygiene. We deliver one-time cleansing engagements as well as ongoing managed services.
