What's the best way to dedupe Salesforce?

Built-in for basics. Fuzzy apps like Cloudingo or RingLead for pros. Set multi-field rules: name + company + email domain.

How much do CRM duplicates really cost?

Time: 20-30 min/rep/day. Emails: 40%+ overpay. Reports: skewed quotas. Ballpark $100K+ yearly mid-size.
