I thought we learned that we don't multiply by the percentage, but instead divide by it to make more money.
100 x 1.2 = 120, but 100/.8=125...
you should be billing with margin, and not mark up...
also, brian's method works well in commercial...but not so well in residential when the customer says "but that outlet only costs $0.49 at Home Depot"
