Before going out of business and getting into the distributor/manufacturing end of this trade, I used a couple of different systems that were very generic.
The systems I see now are what I consider too complex for normal needs, but I suppose they can be toned down and fine tuned to the contractors needs. One such system is designed by Nitek and is being used by Goodman under the name A-Plus Wizard.
This particular program incorporates customer data, load calculations, sales programs and flat rate systems all in one program. You can utilize what you want and disregard what you don't need.
We have a completely web based software program that handles estimates, work orders, invoicing, Quickbooks integration that many of our customers use to deliver estimates and proposals right on-site. For a free demo visit
