If multiple users in your HubSpot account work together on a deal, you can add them as collaborators to keep track of those involved. Once a user is set as a collaborator on a deal, they can view, edit, or delete the deal. Each collaborator can also access a default view that lists all deals they're included on.
Deal collaborators don't receive credit for the amount of the deal, so if any collaborators need monetary credit, you should add them to a deal split (SalesHub Enterprise only). Users can be included both in a deal split and as a collaborator for the same deal.
In your HubSpot account, click the settingssettings icon in the main navigation bar.
In the left sidebar menu, navigate to Objects > Deals.
Select the Allow users to add collaborators checkbox.
Add collaborators to a deal
Once deal collaboration is turned on in your settings, users with Edit deal permissions can add collaborators to a deal. Users automatically gain view, edit, and delete access for any deals in which they've been set as a collaborator.
