Michael, you have a good point. However, Salesforce is the same and more. But like Salesforce, ZohoOne does come pre-configured for most businesses, AND they also have a simple small business option called "Bigin" which is introductory user-friendly CRM. But if the business wants to upgrade later to a more feature packed version of regular CRM, they have that option. But in addition to all that, there are another 45 applications that are avaiable that a company would have to pay for. For example there's a calendaring app similar to calendly, and there is an option for signed documents similar to Docusign, except in Zoho it is free but Docusign is another $25/month for the standard edition.
There's always a learning curve with any new app. But while I understand what you are saying, Zoho has unparalleled value. But it can be hard but that is because it can be used for more complex things. Automation, marketing, social media, and so much more is included which can add up to thousands of dollars if done separately. Plus, since Zoho develops them in-house, they are all tightly integrated together.
$45/month for 45 applications is the best deal a startup company is ever going to get. Also, their support is just amazingly good. A few glitchy service people, of course, but that's normal - just have to call back another day to get someone else.
As you can tell, I'm a total evangalist on Zoho. 🙂
