Using a Service Item for Shipping/Handling Charges
Service Item Overview | Making a Sales Receipt
To charge for shipping and/or handling, you can set up a service item in inventory called "Shipping Charges" or similar.
If shipping charges are taxable in your area, assign the appropriate tax code to the item and optionally map the shipping charges to the appropriate QuickBooks financial software income account on the item record. You can enter your standard shipping charge as the item price or leave the price at zero (0) and edit it on a sale-by-sale basis as you create receipts.
When creating a receipt, list the shipping charge item on the receipt in the same manner as other items. Sales tax will be calculated and added for the shipping charge item, if applicable.
