Act! vs Zendesk Sell: Which is best for you?

Over many years of use, I have consistently felt confident that sensitive contact information, notes, and communications are well protected and appropriately managed within the system.

They have added a mobile app (that was lacking before and the reason I almost left), added project and pipeline management, and interactive quotes to name a few of the new features. When I switched to the cloud, I had an issue getting my database converted. As I was struggling with that, my phone rang.

The software is good in managing sales, I like the report making which you can use to create a report that can be exported for offline reading and analyzing of sales data

Cannot use it alone, it has to integrate with other Zendesk products, but only with Zendesk products. And customisation can be a real headache, as it needs to be completely setup before getting its full potential.
