1st yr mowing commercially.. mowed past 2 yrs with 21" mowers, so just learing the buisness... for those of you doin mulch/stones/fertilizing/etc.... when your pricing it out for the customer.. is their profit made from your materials/seperate from the man hrs?? or just an added part on what you paid EXACTLY for the materials? or just a small raise for having to retrieve the materials (possible storage, if you stock) but which really isnt profit...??? i.e. when I take my car in and have the brakes done, the man hrs are there and the cost of the brakes (which they have made profit the same as autozone wouldve if they had sold me the brake pads) also could ya guy check my sentar/stander post and give some suggestions?
