CRM Data Hygiene – Duplicate Guard

Detect duplicate CRM Leads/Opportunities and Contacts. Warn or block saves with override and audit. Works across UI, API, and automated flows.

Odoo 19 Contacts & CRM Multi-company Warn / Block Override + audit
What it solves: Prevent duplicate Contacts and Leads by matching email, phone, VAT, and more. Choose Warn (show matches, allow save) or Block (prevent save unless override with reason). Overrides are logged for audit.
Watch Full Demo
Duplicate Guard CRM - Overview Configure rules, match keys, and enforcement (Warn/Block). Override with reason; all overrides logged.

Warn or Block

Warn: in-form ribbon and “Possible Duplicates (n)” smart button; save allowed. Block: prevent create/write unless the user overrides with a mandatory reason.

Fields to Match

Select model fields for duplicate detection (email, phone, VAT, website, name, ref, etc.). Pre-filled by default per model. Add or remove fields as needed.

Override + Audit

Authorized users can bypass block by checking “Override duplicate check” and entering a reason. All overrides are logged in Override Log (Settings → Duplicate Guard).

Video Demo

Duplicate Guard CRM - Demo

See Duplicate Guard CRM in action!

Configure rules, see warn/block in action, and use the override flow with audit log in this short demo.

How It Works

1) Define rules
Go to Settings → Duplicate Guard → Rules. Create a rule, pick the model (Contacts or Leads/Opportunities), enforcement mode (Warn/Block), and match keys. Optionally set domain filter and company.
2) Detection on create/write
When users create or update a Contact or Lead, applicable rules run server-side. Duplicates are found via normalized fields (email, phone, etc.). WARN shows matches and allows save; BLOCK stops save unless override.
3) Resolve via Odoo merge
Use the “Possible Duplicates” smart button to open the list of matches. Resolve via Actions → Merge (Contacts) or Odoo’s lead merge flows—no custom merge engine.

Screenshots

Duplicate Guard Rules

Duplicate Guard - Rules configuration

Define duplicate detection rules in Settings → Duplicate Guard → Rules. Choose the model (Contacts or Leads), enforcement mode (Warn/Block), match keys, and optional domain filter.

Duplicate Warning on Form

Duplicate warning on lead or contact form

When a duplicate is detected, the form shows a ribbon and the “Possible Duplicates” smart button. In Warn mode you can save; in Block mode you must override with a reason or resolve duplicates first.

Merge Wizard

Merge Wizard

Use Odoo's merge wizard to merge duplicates.

Common Use Cases

Contacts (res.partner)
  • Duplicate detection by email, phone, VAT
  • Warn or block new contacts matching existing ones
  • Override with reason; fast access to Actions → Merge
CRM Leads / Opportunities
  • Duplicate detection by email, phone, etc.
  • Ribbon and smart button on lead/opportunity forms
  • Use Odoo’s merge behavior; avoid merging lost leads or different salespersons

Key Features

Detection & Enforcement
  • Server-side duplicate check on create/write (no client bypass)
  • Normalized fields (email, phone, VAT, domain) stored and indexed
  • Default match keys pre-filled per model; add extra fields for custom fields
  • Domain filter (domain widget) to restrict scope
  • Multi-company: global or company-specific rules
  • Candidate limit to keep queries lean
Visibility & Governance
  • Ribbon “Possible Duplicates” when matches exist
  • Smart button “Possible Duplicates (n)” opens match list
  • Override only for users in rule’s override group; reason required
  • Override Log with user, rule, reason, match summary, matched IDs
  • Compare wizard (optional): side-by-side key fields
  • Open matches wizard to jump to duplicate list from block flow

Limitations & Not Included

Out of scope for this module:
  • No automatic merges — Duplicate Guard detects and warns/blocks; merging is done manually via Odoo’s built-in merge wizards (Contacts or Leads).
  • No dedupe automation — No scheduled jobs or bots that auto-merge or auto-delete duplicates; you stay in control.
  • No data enrichment — No external APIs to fill or clean contact/lead data; matching uses only the fields you configure.
  • Leads and Contacts only — Rules apply to crm.lead and res.partner; other models are not covered.

Why Duplicate Guard CRM?

Focused on detection, governance, and audit inside Odoo: server-side rules, warn/block with override, and a clear override log. No lock-in to external services—configure match keys and enforcement per model and use Odoo’s native merge when you decide to consolidate. Ideal for teams that want duplicate control without automatic merges or third-party enrichment.

Configuration

  1. Go to Settings → Duplicate Guard → Rules
  2. Click Create and set Model (Contacts or Leads/Opportunities)
  3. Choose Enforcement mode (Warn / Block) and Fields to match (pre-filled by default)
  4. Optional: Domain filter, Company, Override group, Exclude archived
  5. View overrides in Settings → Duplicate Guard → Override Log

Technical Notes

Performance
Normalized fields enable exact, SQL-friendly matches. Candidate search is capped (e.g. top 20). No heavy “contains” searches. Name+company matching is conservative to avoid false positives.
Security
Only admins manage rules. Override is restricted to the rule’s override group; reason is mandatory. Duplicate list respects record rules (no cross-company/team leakage). Error messages avoid leaking confidential data.

Ready to Reduce Duplicates?

Install Duplicate Guard CRM and configure your first rule in minutes. Prevent duplicate Contacts and Leads while keeping full audit control.
