Batch Price List is the place that you can change all product’s prices and portion prices of those products through a single screen. To update batch product, on navigation screen go to Manage > Products > Price List Editor.

Write the new price by double clicking on the item that you want to change the price. The line which price has been updated, seems bold. That bold means there is an update for price but not saved yet. After editing price process, if you click on Save button, related item’s price will be updated.
