The ease of use - really, there isn't much I don't like about this program. It does exactly what you need it to do in order to get your bids out quickly and accurately without having to spend a lot of time learning how to navigate an interface not made by my favorite web browser (Internet Explorer). This helps us manage our projects so we can keep up with them! There aren't any specific problems at this point - but if there are please let me know! We have been able to save tons of time using Turbo Bid. Our project managers can now enter information into their jobsite database quickly instead of waiting for someone else to come over and help. And they can access all aspects of the job from anywhere thanks to our mobile devices as well.
