Is there a way to get reports on certain employee's productivity?

You can produce time reports as well as assignment reports using Basecamp.

There are not formal reports but you can look at users' activity

The phrase "Under activities" in the context of the Unknown Language could be translated to English as "Beneath activities" or "Below activities," depending on the specific context in which it is used.

Agree that there are no standard reports. However, if you really want to develop a custom report, try integrating Basecamp with something like Zapier to create data you want.

You can view their activity like conversation and completed to-dos' but there are no reports.
