How to add inward trasnportation expenses (Inward Shipping) in purchase bill?

Allow me to share some insights about handling this process in QuickBooks Online. If you need to add another amount to account for the shipping expense, you can create a service item and map it to an expense account. 

Add a new expense account to your chart of accounts for the shipping.

1. Go to Settings ⚙ and select Chart of Accounts.
2. Select New to create a new account.
3. In the Account Type ▼ dropdown, choose Expense for the account type.
4. In the Detail Type, select the detail type that best fits the transactions you want to track. Learn more about detail types.
5. Add any missing information then select Save and Close.

Add a service item to use on your purchase transactions. Follow he steps below:

1. Go to the Gear icon and select the Products and services menu.
2. Press New.
3. Uncheck the tick box for I sell this product/service to my customers.
4. Select I purchase this product/service from a supplier.
5. Add a description. This shows on bills, purchase orders, and other forms you send to suppliers.
6. Add the Cost. If the price changes, don’t worry. You can still enter the updated price when it’s time to buy supplies.
7. Click on the Expense account ▼ dropdown and then add the account you created earlier.
8. When you're done, select Save and close.

Now you can add this service item on your purchases together with the items you bought from the supplier.
