Service based companies using ZOHO?

Service based companies using ZOHO?

I own a service based company, we service our clients weekly monthly etc.  I use ZOHO CRM to manage all of my clients, I was wondering if there are any service companies that are also using ZOHO.  I need the ability to automatically change the next service date once they are done servicing the client.  Is there anybody else using this kind of functionality with ZOHO?
