It has been very easy for our organization as we are able to track all of my clients' projects with this software! The interface could be improved when it comes time in order so they can update their own information easily instead or having them send me an email each week asking if I have updated anything since last Tuesday etc..
We use Mgt IT because its what every other major contractor uses within there industry/marketing group (AECO). The ability for everyone in our organization (project manager/owner) can view all of their projects at once! It's easy enough so we don't have any issues with it but I wish there was an option where you could see only one page per user as well - maybe this will be added down the road? We are using Maintain IT mainly because its cloud software which has been great since most people do not want or need desktop applications anymore due too security concerns etc..
