Delivery Charges allow you to place delivery fees on Orders over or under a certain total. Each Delivery Zone can have it's own unique charge, which helps account for different distances to travel and accommodate for Customers across various locations.
Go to Setup > Organization > Delivery.
Click the orange pencil button near the Delivery Zone to add a Charge to.
Add the Delivery Charges for Orders Less than or More than a certain amount.
Each Site has to have it's own Delivery Charge entered this way.
Check "Charge as % of Order Value" to create a Delivery Charge by percent of the Order Value, rather than a set amount.
If needed, add a different Tax Code or Tax Exempt Code to the Charge.
Once set, click Save Details.
