The best thing about Clientrol is that it has an integrated CRM which helps in managing all your clients. It also has a great dashboard where you can see all the information regarding your clients. I like that it's easy to create new projects and tasks. Sometimes it takes a while to get some info from the dashboard or when sending emails sometimes it gets lost or not delivered. Also, sometimes it doesn't show up in my inbox. If you're looking for a tool to manage all of your clients then this is the right one. You can easily add new contacts, send invoices, track payments and much more. I've been using Clientrol for 2 years now and I have never had any problems with it so far.
