The best thing about p3source is that it has an easy to use interface which makes my life easier when managing large volumes of work in different stages for our agency clients. I have had no issues with any part of the product so far but there are some minor bugs here nd there like sometimes you get stuck or something pops up saying "unable to add document" while adding documents into your portfolio. It's not too much hassle as we can easily fix these small things by contacting their support team who responds very quickly & efficiently. We've been using PS since 2012 now till date without facing any major problems. My client base keeps increasing every year because they know how efficient i am at handling multiple projects simultaneously.
