Included in your bill should be the amount of labour charge, itemising

You seem to have fundamental lack of understanding of how a commercial
enterprise needs to work. If you simply pass good through your business
at the "price you paid", you are losing money on every single one.

I don't see why that should be the case. Where it is customary to charge
customers on a time and materials basis, it's perfectly OK to charge for
materials "at cost" (without markup), but instead to make sure you count
the time involved in procuring said materials.
