How to Unmerge Deals in HubSpot (2026)

Can you unmerge deals in HubSpot?

No. HubSpot's knowledge base answers this directly in a section titled "Can I unmerge records?": "It's not possible to unmerge records." The statement carries no exception for deals. The only documented workaround, creating a new record from an additional email or domain name, applies to contacts and companies, not deals.

That answer comes from HubSpot's own merge records documentation, and the community has confirmed it for years. So take a breath: the merge cannot be clicked undone, but the situation is recoverable, and the first step is understanding exactly what the merge did.

HubSpot does leave a trace. The surviving deal keeps a property named Merged deal IDs containing the Record ID values of all deals previously merged into it. Hover on the value and click Details to see who performed the merge and when. To find it, open the deal, click Actions > View all properties in the left panel, then search "Merged".

What actually happens when two deals are merged?

The primary deal's property values win by default; the secondary deal's value is used only where the primary has no value. All timeline activities from both deals are combined onto the surviving record, and all associated records from both deals are combined onto it as well.

This is why a merged deal is hard to take apart by hand: the survivor is a blend. Property values from the secondary deal either carried over (where the primary was blank) or lost out to the primary's values, often leaving property history as the only place they still appear. And the emails, calls, notes, and tasks of two separate deals now sit on one timeline, per the documented merge behavior.

How do you manually rebuild a merged deal?

Create a new deal and repopulate it by hand. Open the surviving deal, check the Merged deal IDs property to confirm what was merged and when, then review each property's history to find values that belonged to the lost deal, and copy them into the new record.

1. Confirm the merge. On the surviving deal, click Actions > View all properties and search "Merged". The Merged deal IDs property lists every deal that was merged in; hover the value and click Details for who did it and when.
2. Create a new deal. Give it the lost deal's name, pipeline, stage, and amount as best you can determine them.
3. Copy values from property history. Because the primary's values won the merge, values that belonged to the lost deal may now exist only in the surviving deal's property history. Work through the properties that matter and copy the right historical values into the new deal.
4. Rebuild context by hand. Re-associate the correct contacts and companies with the new deal.

One route that will not help here: HubSpot's Export merge history option (Data Quality > Manage Duplicates > Actions) does include property values prior to the merge, but it only covers merges performed in the duplicate management tool, and that tool compares duplicates only for contacts and companies. There is no documented merge history export for deals.

What can a manual rebuild not restore?

Activities and associations. Emails, calls, notes, tasks, and meetings from both deals were combined onto the survivor during the merge, and HubSpot documents no way to split them back apart. Associated contacts and companies were combined the same way, so the new deal starts empty and disconnected.

• * Activities: the combined timeline stays on the surviving deal. A manually created deal begins with no history.
• * Associations: you can re-associate records by hand, but nothing tells you which associations belonged to which original deal.
• * System fields: the new deal's create date reflects the day you recreated it, not the original deal's timeline.
• * The recycle bin: HubSpot's restore deleted records article never mentions merged records, so there is no documented path to recover a merge loser from the bin.

A calm word of caution: do not delete the surviving deal in the hope of resetting things. Deleting and restoring it is not a documented way to undo a merge, and the survivor is the only record that still holds all of the combined data and its property history.

How does Emergency Unmerge unmerge a deal?

Emergency Unmerge rebuilds both original deals from the surviving record's property history, timestamps, and association patterns. Install the app, run a free scan from the sidebar card on the deal record, generate a reconstruction plan, then review every field with confidence scores before executing. The whole flow takes about five minutes.

How much does it cost to unmerge a deal?

Scanning is free, and credits start at $4.99 for 100. A typical deal unmerge costs 15 to 100 credits, which is $0.75 to $5.00. Chain merges involving several records run 100 to 850 credits. The free scan quotes the exact credit cost before you commit to anything.

Credit packs: 100 credits for $4.99, 250 for $9.99, or 500 for $19.99. Per-credit purchases are $0.05 each ($0.04 at 250 or more, 100-credit minimum). No subscription, and credits never expire. Full details on the pricing page.

How do you prevent the next bad deal merge?
