How do I account for freight and other service items in TidyStock?
Create a material category for freight in TidyStock and map it to the appropriate Xero account. Also create an unmanaged item called "Freight Charge" or something similar and set freight as its material category. Once the item is created, edit the item and remove the number within the Stock Level field to make it blank. This will make the item non-depleting.
You will now be able to select freight as an item on Sales Orders.
