I think what matters most is the total kg to be used which will have decimals. One issue will be the decimals will not be universal i.e. decimals places will vary each order.
This will also affect cost/price calculations as these should be calculated into the orders. Basically the FG/whole bottle will have a cost/price each, etc. Then for specifics we'll see how much kg was used. We'll have BC average them as we'll assign them a lot# so then we will sell in bulk quantity.
Is there something extra we'd need to do while setting up these items, etc.?
