Been researching this... and we are still using a calculator to figure markup/cost % on jobs.  Wishing there was a 'job budget' or 'GP %' listed for cost vs. total job price.  There is to much time invested in breaking down cost and retail for hundreds of line items we use between materials and labor, where the items come from, ect- just for all of this useful information to not populate where it is needed (i.e. on the estimate screen we use when bidding on jobs).
