item pricing can be derived in multiple ways and additional cost may apply to one set of items but not another. Breweries can have hundreds of products and depending on if they are taproom related or production related price modification could relate to 10ās of products but not others.
If pricebooks can be downloaded they should also be able to be uploaded to allow bulk and targeted modification of pricing or rules in bulk. This would save a lot of time and effort as apposed to individual item changes.
