I expect an electrical contractor to keep an inventory of common materials in his truck. The cost of maintaining that inventory should be close to 5% not 100%. Considering his discounts from retail, I would expect to be charged RETAIL for common materials.
welcome to 2006. There are no real discounts for contactors anymore. The only discounts are from manufacturers listed Retail Pricing. Do you think that I pay 50% less for a receptacle at the supply house than you would pay Retail at Home Depot?
You can earn easily 6-10% in a Mutual Fund. The smart contractor would put their money their and just purchase invetory as needed for each job. But for someone to assume that we should front the money, store the product, utilize it on their job (for their convenience) and only mark it up 5%?
George don't feel bad, I would never work for someone who presumed to know my expenses to provide them with quality work and great service.
Good luck.
