We sell groceries at a large scale with more than one UoM. In the past we would be writing those down, on a receipt for the customers to be able to see it. I don't know how to do to let the customer know how much are they actually buying from us on the e-commerce and also on the default receipt. Is there a key for it to display those UoM on the receipt and also on the E-commerce. It's ok to not to display on e-commerce while the customers are shopping. But, it would be very good for the customers to know that how much they are actually buying after checking out with the invoice and the receipt.
