Does anyone out there know a simple way of developing your markup on materials. This may not apply to everyone here but perhaps Phil and the guy from Compass can help with this. It has just come to my attention that I may be a little (LOT) cheaper than my competition on parts. We service sprinklers and I have been selling an item for $27.50 that I buy for roughly $11.00. I have always thought this was huge markup but now I hear that a couple of other competitors are getting $44.00 for the same item. Also, some items that I buy for less than .50 , I resell for $1.00 and they are selling for $5.00. Is this highway robbery or good business? How do I explain to my regular customers, if asked, that I raised the prices almost 100% of what they are used to because "everyone else is".? Help!
