Why did new deals suddenly jump in Zendesk Sell?
The Zendesk Sell help pages give 3 common reasons. The first to rule out: A deal import adds every deal in the file, so one import can add many new deals on the same day.
Is it broken, or just quiet?
A number can fall because fewer people came, or because something stopped counting them. Below are the causes the Zendesk Sell help pages give, and how to check each one yourself.
What causes it?
A deal import adds every deal in the file, so one import can add many new deals on the same day.
In the Zendesk Sell help:
All deals are added in your import.
Importing deals using a CSV file, read 2026-11-12.If the file has no date for when each deal was added, Sell uses the import day, so older deals can count as new on that day.
In the Zendesk Sell help:
If you don't include information for the Owner of the deal, or Added on, then the two fields will be added with default values (current user, current date).
Importing deals using a CSV file, read 2026-11-12.Converting many leads at once can create a new deal for each one, so a batch conversion can add many deals in one go.
In the Zendesk Sell help:
When you convert multiple leads in bulk and choose to also create a new deal, the new deal is named after the lead’s name.

How do I check it myself?
If an import added deals by mistake, it can be reverted, and only the deals that import created are removed.
In the Zendesk Sell help:
Only newly created deals are removed.
Importing deals using a CSV file, read 2026-11-12.If your team sets a source on each deal, look at the sources of the new deals in Sell's reports to see where they came from.
In the Zendesk Sell help:
Your sources are also available in Sell’s activity reports so that you can, for example, track how different sources convert.
Tracking lead and deal sources, read 2026-11-12.
How would I know the day it starts?
- Feder reads your new deals from Zendesk Sell each day and compares each day with your own history.
- It tells you when new deals go quiet or move outside their usual range.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
