Auto Double Contacts in Kommo

On the first run the widget scans your entire Kommo account and merges all the duplicates it finds. You can run it over the whole database, over selected IDs, over a period or on 10 random duplicates as a safe test.

Every new or edited contact is instantly checked for duplicates. If one is found, it is merged automatically before it clutters the database. A configurable delay lets contacts merge first and their leads right after.

If a manager creates a contact with a phone or email that already exists, the widget warns them at once. Two modes are available: let the manager attach the contact that was found, or block saving the duplicate completely.

Finds duplicates by phone, email, company name, tax number or any other custom field. Phone numbers are compared by the last 10 digits, so country codes, spaces and dashes are ignored. A match on one criterion is enough.

Set the similarity threshold for names: with the same phone number Elena and Elena Smith are merged as one person, while Elena and Maria are not. In the advanced version the final contact keeps the fullest name.

The whole history is in the Analytics section: what was merged, when and by which criterion. The source report shows which channels bring the most duplicates. Search, manual merging of skipped pairs and access rights are included.

After every merge a system note with an Undo button appears in the card. All data, leads and tasks are kept.

Add a stop list of phones and emails, mark separate contacts with a Do not merge flag field and limit how many phones and emails a card can hold, so it does not grow because of test contact details.

Automatically add a note, create a task, change the responsible user in related leads, send a Telegram notification, run Salesbot or send a webhook.

Do not want to merge automatically? The widget will mark potential duplicates with a tag so your team can review them manually.
