Deal deduplication
Deals can be deduplicated based on mapped field values. For records to match, the mapped field values must be identical in both HubSpot and Salesforce.
For example, if the Order Number property is mapped between HubSpot and Salesforce, deal records with the same order number will be mapped and synced.
Existing matched records aren't affected when you configure the deal deduplication logic. The deduplication settings apply when new deal and opportunity records are matched moving forward, after the updated deal sync is turned on.

Deal merges
Deal merges are supported in HubSpot.
When two HubSpot deal records are merged:
- After merging the HubSpot records, the resulting record continues syncing with the Salesforce record that matches the selected salesforceobjectid value. To control which Salesforce record continues syncing with the resulting HubSpot record, select the corresponding salesforceobjectid value as the winning value during the merge.
- Salesforce records are not merged automatically.
