I am a contractor that works for various large companies. These companies ask me to use my own money to hire trucks and provide sub contractors and buy materials to complete the work. One company that I hire my services insists that I provide them with the original invoices made out to me for payment of the extra services that I have paid for and the Invoices are made out to me. This company only wants to pay me what I have paid and also see who my contacts are. I refuse to do this as I believe I only have to supply them with one Invoice from me with a break down of costs including my percentage for using my own money and time involved to set up this work. This company states legally I have to supply them with original invoices for me to get reimbursed for my costs, is this correct.
