To make entry Sales Orders easier, you can use Sales Price List to give you the flexibility to charge different amounts for your goods based on individual customer, vintage year or even type of sale ie retail versus wholesale.
Creating price lists
To create a price list, head to Winery Setup > Sales > Sales Price lists > New Price list.
You can then set up your price list and include default tax rates and revenue accounts that will be populated on the sales order. The bottom section allows you to add each stock item and it's price as the default when this price list is used.
When you use the price list in a sales order and enter the stock item it will enter the price based on your price list. It will also include any of the additional default information you provided including the tax rate and revenue account.
