DupliGuard – Duplicate Detector for Perfex CRM

DupliGuardfinds duplicate Leads, Customers and Contacts in your Perfex CRM and helps you clean them up safely. Built native to Perfex 3.x, fully self-hosted, no external services, no recurring fees.Every CRM with more than 500 contacts has duplicates. Same lead submitted twice from a landing page, the same customer added under two slightly different company names, the same contact created by two different sales reps. DupliGuard scans all three tables, groups what matches, and lets you decide what to do — one cluster at a time, with full visibility, zero destructive operations.
Why DupliGuard is different
Reviews, never auto-merges.No silent data loss. The buyer sees both records side-by-side, picks the master, then chooses how to resolve the cluster. The original CRM rows are never deleted by DupliGuard.
Three deterministic rules, no ML black box.Exact email, phone (digits-only, last 8 chars to handle international format variations), and email domain. Every match is auditable, reproducible and explainable to a customer.
Built for Perfex, not a generic dedupe library.Knows that Customer email lives on the primary contact, that lead phone formats vary, that converted leads should not be re-flagged. The compare view surfaces the columns each entity actually has.
Self-hosted, source included.No external API calls, no data leaves your server, no monthly fee. Install once on your VPS and own it.
