I like how it has all my information in one place so i can go back later if needed! The interface could be improved by adding more icons for things such as add rooms/floors etc., but this should not make me have difficulty finding what im looking at because its very easy once u learn where everything goes :) It makes managing multiple jobs easier than having them spread out around different applications / websites (i use many)It saves time when working from home since there are no interruptions while doing other tasks during work hours - just log into dcost whenever necessary.
