Zoho - not for the non-tech user

We used it to track the effectiveness of our sales staff. They generated weekly reports, which were sent to management. In our experience, it was too hard to use for our staff, in part because they never embraced it but also in that it was complex. The features were powerful and deep, far deeper than they were willing to use. The phone app was unreliable in logging calls. Some calls from customers or leads were logged, some were not. We could never figure out why. [I feel that ] support wasn't helpful, and we eventually gave up.
