DupliGuard - Duplicate Detector for Perfex CRM

Important: DupliGuard is a module that runs inside Perfex CRM — not a standalone application. You need an existing install of Perfex — Powerful Open Source CRM to use it. DupliGuard — the duplicate detector your Perfex CRM was missing 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.

What’s inside Dashboard

• 4 KPI cards — total groups, lead duplicates, customer duplicates, contact duplicates
• One-click “Run Scan Now” with live progress feedback (no page reload)
• Last-scan banner: when, by whom, manual or cron
• Recent activity log with deep links back to each affected group

Scan engine

• Email exact match— lowercased+trimmed, score: high
• Phone— non-digits stripped, last 8 digits compared (handles +country prefixes and formatting), score: medium
• Email domain— groups records sharing a corporate domain, generic webmail (gmail / yahoo / hotmail / outlook / icloud / proton / etc.) automatically excluded, score: low
• Adjustable minimum-score threshold to keep low-confidence noise out of the dashboard
• Idempotent — safe to re-run any time, groups upsert by (entity, field, value)
• Smart re-detection: a group previously marked Safe re-opens automatically when fresh duplicates appear

Group review

• Filterable groups table: status, score, entity type, match field
• Side-by-side compare view with all key columns surfaced per entity
• One-click “Pick as master” radio per record
• Direct deep link to the original Lead / Customer / Contact in a new tab

Three resolution actions

• Mark as Safe— the cluster is not actually a duplicate (e.g. two siblings sharing one email). Excluded from future scans.
• Mark as Duplicate— flagged for the team’s awareness, no destructive change. Use it when you want to preserve evidence without acting yet.
• Convert to Note— attaches a structured note to the master Lead or Customer listing every duplicate ID, the matched field, the score and the timestamp. Source rows stay intact — you can review the note and decide what to do in your normal Perfex workflow.

Settings

• Per-entity scan toggles (Leads / Customers / Contacts)
• Per-rule toggles (email / phone / domain)
• Adjustable minimum score (low / medium / high)
• One-click cron toggle — wire DupliGuard into Perfex’s native cron tick for hands-off recurring scans

Security & reliability

• CSRF-protected AJAX on every action
• html_escape()on every dynamic value rendered in views
• CodeIgniter query builder only — zero raw SQL with interpolated variables
• Two-tier permissions: view(read-only) and manage(run scan + apply actions)
• Idempotent installer (safe to re-activate), versioned migration framework, clean uninstaller (drops only the module’s tables — your CRM data stays put)
• No external API calls, no telemetry, no third-party JS bundled

Internationalization

• English + Spanish language packs (124 strings each)
• Every UI string runs through Perfex’s _l() helper — ready for community translation
• Full UTF-8, zero mojibake

How it scales DupliGuard’s scanner runs in a single pass per (entity, rule) combination, grouping records in PHP. Even on a 50, 000-row Perfex install the full scan completes in a few seconds. No background workers, no queue dependencies, no separate cron container required — just enable the toggle and the existing Perfex cron tick takes care of the rest
