Integrates well with Google Apps for business
Easy to use; easy for team to adopt
Robust reporting features
Useful across all areas of our business (from management to sales to support)
Room for Improvement:
Doesn't integrate well with Outlook
Took a while to set the system up properly (to reflect our business needs)
Not many apps that we can use to add on.
My company started with Zoho because it was a very affordable alternative to Salesforce, and I'm very happy with our decision. However, as we continued to grow, Zoho did not have all the features we needed to successfully track our sales cycle, so we ended up switching to Salesforce (and this transition. . .whew. . .it was a doozy and took nearly a full week to have everything in order). It's a very good system to use to start out, but you may find that you outgrow the functionality.
