Duplicate contacts, accounts, and leads in Dynamics 365 erode your pipeline data and frustrate your sales team. DeDuplica detects every duplicate pair, applies your merge rules automatically, and keeps your Dataverse clean — on a schedule you control.
Every duplicate contact or account in Dynamics 365 is a risk — wrong owner assignments, split engagement history, inaccurate pipeline reports, and embarrassing double-outreach to the same customer.
Two contacts for the same person means email history, call logs, and opportunities sit on different records. Your team never has the full picture.
Duplicate accounts and contacts double-count pipeline values and lead volumes, making forecasts and territory assignments unreliable.
Dynamics duplicate detection uses exact or basic wildcard matching. It misses name variations, abbreviations, and phonetic matches that are obvious to humans.
Reviewing and merging duplicates one by one inside Dynamics is a full-time job. It never gets ahead of the rate new ones are created.
Add your Dynamics 365 / Dataverse environment as a connection in DeDuplica. Authentication uses your Dataverse credentials — no custom connectors or middleware required. Works with all Dynamics 365 versions (Sales, Customer Service, Field Service, and more).
Choose any Dataverse table — Contact, Account, Lead, or a custom entity. Configure matching fields using comparators that go beyond what Dynamics offers: Jaro-Winkler for name variations, Metaphone for phonetic matching, Person Name for first/last name permutations. Set Rank per field and overall Strictness to tune precision.
DeDuplica can merge duplicates directly in Dataverse using the native merge API, applying your field-level merge rules (keep base, keep most recent, keep non-null, append text, and more). Or route duplicates through webhooks for your own workflow — every found pair includes the full merge output JSON. Schedule runs to keep Dynamics clean continuously.
Jaro-Winkler, Levenshtein, QGram, Metaphone, and Person Name comparators catch duplicates that Dynamics exact-match rules miss entirely.
Confirmed duplicates are merged directly in Dataverse using the platform's own merge API — related records (activities, opportunities, cases) are re-parented automatically.
Keep the base account number but use the most recently updated email. Keep the longest address string. Sum numeric fields. You define the rule per field — DeDuplica builds the merged record.
Run against Contacts, Accounts, and Leads on separate schedules. New records imported overnight are deduplicated before anyone opens their CRM in the morning.
Mark a pair as "not duplicates" and DeDuplica remembers. Parent and subsidiary companies, or people with the same name, won't surface again as false alerts.
Route every found duplicate to a Power Automate flow, Azure Function, or any HTTP endpoint. The payload includes both records and the pre-built merge JSON.
Many organisations have customer data in more than one system. DeDuplica connects to all major enterprise databases from a single platform — so you can extend deduplication beyond Dynamics without switching tools.
