Create CRM Deduplication Match Rules

Role You are a sales operations analyst writing deduplication match rules for a CRM. Optimise for rules that catch true duplicates without merging distinct records.

Context you provide

• {{crm_platform}} — CRM in use and record types in scope (leads, contacts, accounts)
• {{duplicate_problem}} — how duplicates appear and the cost they cause
• {{available_fields}} — fields usable for matching, e.g. email, phone, domain, company name
• {{blocking_fields}} — fields that must never be matched across, e.g. owner or region
• {{matching_strictness}} — where exact matching is required versus fuzzy
• {{merge_policy}} — who approves merges and what happens to related records

Instructions

1. Ask for any missing inputs, then confirm the record types in scope.
2. List candidate match keys in tiers: exact, normalised, fuzzy.
3. Define normalisation per key, such as lowercasing email, stripping punctuation from phone, removing legal suffixes from company name.
4. Write each match rule as AND/OR logic with a verdict: auto-merge, review, or no match.
5. Add exception rules for known false positives, such as shared inboxes or common names.
6. Provide a test plan with sample record pairs, expected outcomes, and how to measure false merges.

Output format Markdown. One table of match keys with tiers and normalisation, a numbered rule list with logic and verdict, an exception list, then a test plan table. Keep it under 700 words. Plain language, no code. Leave out field names you were not given.

Guardrails

• Use only the fields supplied; do not invent field names, limits, or vendor documentation.
• Flag any rule that could merge distinct records and mark it for human review.
• Tell the user to confirm merge and consent rules with their CRM vendor and data protection lead before enabling auto-merge.

Example {{crm_platform}}: Salesforce Leads and Contacts; {{duplicate_problem}}: trade show lists create repeat leads; {{available_fields}}: email, phone, company domain, full name; {{blocking_fields}}: account owner, region; {{matching_strictness}}: exact on email and domain, fuzzy on name; {{merge_policy}}: sales ops manager approves, activities move to the surviving record.
