I've used just prImp in two different companies, one being my current job which has been running smoothly since i switched it over from Outlook calander that gets so many emails wrong time wise! They are constantly updating everything as far as new features go but there isn't anything bad coming out this side!! Highly Recommended. The only thing they could change would be having something else other than outlook calendars available when you sign up because some people use those things also plus all your contacts should have easy access of who's contact info what services do you offer etc.. So if anyone asks me or looks at these websites before making any decision don' t look anywhere elses then here cause its where u need too get answers not through others words I love that they have a free version so you can test it out before going all in. The customer service has been great as well, helping me figure out how to use the product and solving any issues I had along the way. I would like to see maybe some new options for scheduling or adding more clients/appointments into the system. Make sure this works for you! The benefits are being able to set my own hours, be my own boss, and make money online while working from home!
