When repeated customer records make sales and CRM data harder to manage, deduplication tools can help identify and handle overlaps. Compare fuzzy matching and duplicate prevention to see how options approach matching records, then check automatic merging and the merge review workflow for how changes are handled. CRM integrations and API access offer points to assess fit with your existing systems. Free-plan availability and the paid-from price add cost context. Workbooks, DupeCatcher, and Plauti Deduplicate are among the entries to consider as you weigh those capabilities against the way your team manages customer data.

27 data deduplication software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
