It's easy to use, it has all of my submittals in one place with links back out so I can easily see what needs attention or when something was submitted that should have been done earlier etc.. The pricing structure could be more user friendly but overall this program works great! We are using HDP as our main construction document system which makes managing costs much easier than having multiple spreadsheets open at once while working through different aspects/sub-projects within an individual job site file folder.
