Yes, but at some point a purchase order has to be drafted and a contract has to be signed. Those things should be spelled out in detail.

I'd think the big company would almost demand that or else the coffee roaster could ship 6000 zip lock baggies with 10 coffee beans in each. I know that's an absurd example but a PO and contract protects everyone against that and that's why any reasonable company doesn't proceed without defined terms.
