We use One Click to manage most of our clients and they are super helpful!! I love that you can log in with your Google or Facebook account and be able to access it all right away. It's so much easier than trying to remember login information for each client. So far, I haven't really had any issues - which is good because I am not usually one to complain. If you have any questions, just email them and they will help you out. They also have a free trial to check everything out before committing to purchase. This software makes managing our clients' accounts sooo easy!! All we do now is enter new leads via our script and they are set up and ready to go.
