Hi @RRubright that’s correct, a ticket has several date properties by default, including create date, close date, last activity date, etc.
You can create a custom property for Due Date that you can add to reports, views, etc. by going to your HubSpot Settings > Properties > Ticket Properties > Create property:
Then choose Date Picker as the field type:
Then set the rules you want the date property to follow:
I recommend starting with any date, that way if someone forgets to add the due date, it can still retroactively be added.
This custom property can then be added to your ticket sidebar so its visible in the conversations inbox, etc.
I hope this helps get you the information you need!
