I like that it's very easy to use for estimating purposes as well! It allows me access from anywhere with an internet connection in order to view my estimates/bids without having them stored locally or saved on hard drives (my laptop has died many times over).
Also being able to have multiple users log into one account makes things easier when you're working remotely sometimes too!! Not much at this time but would love if they had some sort of mobile app available so we could be notified via text message about any new bids submitted while away somewhere else - just something small maybe? We are using pipeline suite primarily through our subcontractor who uses PCAsoft along side us also allowing all parties involved greater ease regarding communication throughout construction process.-easy estimation capabilities & quick response notifications.
