How to account for items sold at cost price (to avoid distorting net profit figures)

Andrew_8635213

I have supplied a good friend with substantial order at cost price, Just looking for suggestions on how to account for this so that the net profit figures are not distorted. Obviously it will bring our net profit percentage down selling a high value invoice at cost price. I could just put it on our partner account (as though we were making a personal purchase through the business), but I then I can't create an invoice that my friend requires.
