I like how easy it is for me as an estimator/owner's rep/builder to use this software with my team members. It does what we need very well! I also love being able to send out mass emails from within the program too which saves us time in our day-to-day activities. The only thing i dislike about discover construction was when they changed their pricing model so now each user has different plans depending where your business falls into the system (small or large). If all users are small businesses then there isn't much of a difference but if some have larger companies than others then price increases can be quite steep. We were using excel spreadsheets prior to discovering.
