I'm going to be bidding on my first large scale job that came to me as an open tender. I need advice on a specific area of the tender where the client is asking for the rates of the tradesman who will be doing the work. This is fine, no problem. 75$ an hour. Here's where Im lost...They then go on to require I list the "material discount" I will be offering them. This is where I'm confused because they show an exampleof a previous tender, and the example shows a material discount of -3.50% . Now, in most business practices to me, usually a company will "markup" any materials and sell them back to the client at the marked up rate, usually 10-40% or whatever. Does this client expect to get money taken off of retail prices? Is this what they mean by "material discount", or is it fair to assume that everyone will be marking up the rate? Does the negative(in this example) mean that the reatil price is actually -3.50%, is the company taking a loss? How do I proceed, do I take a loss on material or what? Thanks very much!
