I own a HVAC Commercial shop with my brother in Chicago. We are bidding so much work right now it is getting really hard to keep up with. As of now we have been doing all of our estimating by pencil and ruler. All of the take-off duct work takes some time and then putting our formulas together that have been in the family since the 80's. My Grandpa started the business in mid 80's. We have updated things to adapt to the times obviously but does anyone have advice on the best software to use for bidding purposes? We go after all commercial work... Grocery stores, retail stores, etc. I have looked at Wendes, Fast Duct, Cloud Take-off.. I am starting a 30 day trial on Wendes starting Monday. Any input whatsoever is much appreciated. Thanks
