  1. 01Agree the required-field set

    A hygiene dashboard that surfaces likely duplicate records and missing required fields so the team can see how clean the data is before they trust...

  2. 02a view that flags probable

    Build a view that flags probable duplicate clusters and counts missing required fields per record.

  3. 03Supabase Postgres

    Supabase Postgres contributes the trusted model for CRM Hygiene Dashboard for Duplicate so metrics are defined before they are visualized.

  4. 04SQL view

    Compute a simple hygiene score and trend it so cleanup progress is visible week to week.

  5. 05Review Queue

    When automation confidence is low, route the record to a manual owner with the source, stage, and last action attached.

  6. 06Dashboard Action

    Probable duplicate clusters flagged for human merge; Missing-field counts surfaced per record; Hygiene score trended so cleanup progress is visible...

Problem

The operating gap

Reports built on a messy CRM lie quietly: duplicate contacts inflate counts and blank fields break segments, but nobody sees the rot because no view measures it — the data looks fine until a number is obviously wrong.

Build

What gets built

A read-only hygiene view that fingerprints records by normalized email/phone to flag probable duplicates, counts missing required fields per record, and trends the hygiene score over time. It is purely diagnostic — it reports what is dirty and where, leaving the actual merge/cleanup decision to a human.

Build steps

How it ships

CRM Hygiene Dashboard for Duplicate and Incomplete Records uses a reporting model and review layer for Dashboards. A hygiene dashboard that surfaces likely duplicate records and missing required fields so the team can see how clean the data is before they trust... The architecture connects agree the required-field set, supabase postgres, sql view, and dashboard action with an explicit control path.

  1. 01Agree the required-field set and the dedup fingerprint rule (normalized email, normalized phone) with the operator.
  2. 02Build a view that flags probable duplicate clusters and counts missing required fields per record.
  3. 03Compute a simple hygiene score and trend it so cleanup progress is visible week to week.
  4. 04Render a 'top duplicate clusters' list and a 'most-incomplete records' list for triage.
  5. 05Mark this view explicitly read-only so it diagnoses rather than auto-merges anything.
  6. 06Document the fingerprint rule and score so the definition of 'clean' is shared.
