Can anyone help? My wife has been asked to prepare a food product and has been asked to submit an invoice for costs time etc. She has never done this before it has started a discussion on doing this. We could do an invoice just to cover ingredients which I would be happy with but I would also like to know the true cost of the product for future reference.
Does anyone have any experience of doing this or any advice on how to properly cost out a product and what items would be reasonable to charge for , or is there a rule of thumb used and then a % added for reasonable profit.
We are totally in the dark so any help or advice would be appreciated.
Kind regards SBM
