How to Audit CRM Data Quality: A Practical B2B Checklist

Measure completeness before accuracy

Start by counting what is missing. Completeness is cheap to measure and it usually explains most of the pain a sales team reports: unroutable accounts, unsegmentable campaigns, reports that exclude half the pipeline.

Run the count per field and per segment, not across the whole base. A 90% fill rate that hides a 40% gap in your priority vertical is a misleading number.

Find duplicates by entity, not by string

Matching on company name alone will miss trading names, legal suffixes and group subsidiaries. Match on website domain first, then registered identifiers where available, then name as a fallback.

Report duplicate clusters with the record count and the owner of each record. Merging without knowing who owns what creates the next data dispute.

Test field accuracy on a sample

Accuracy cannot be measured from inside the CRM. Pull a random sample of 200 to 300 records per critical field and re-verify them against current public sources.

The resulting error rate per field is the number that should drive the remediation budget, not a general sense that the data feels stale.

Check freshness and ownership

Every record needs a last-checked date and an accountable owner. Where either is missing, the record is unmanaged by definition and will drift again after any cleanse.

Prioritise remediation by impact

Fix the fields that change routing and segmentation first, in the segments with active campaigns. Full-base remediation before the intake process is fixed simply resets the clock.

What a first audit usually finds

The pattern repeats across CRMs: high fill rates on fields captured at form submission, poor fill rates on fields nobody is accountable for, and a duplicate layer concentrated in the accounts with the most activity.

That last point surprises people. The accounts your team works hardest are the ones most likely to have been created twice, because more people touched them.

Turning the audit into a plan people will follow

An audit that reports twenty problems gets shelved. An audit that names three fields, the segments they break, and the cost of leaving them broken gets funded.

We deliver the full field-level table for the record, then a one-page remediation order with an owner against each line. The intake fix always goes first, because remediating before it is in place means paying twice.
