Do you have customers that don’t need to pay the beer duty, such as exports? You can now mark these customers as such (edit the customer) and Breww will take the nominal duty amount off of the price of the product in their price book for you automatically when creating orders.
We’ll show you a notice on the order that this is happening to avoid confusion. We also now show the nominal duty amount for each product on the product page, so you always know what this amount is.
