How to record UPS purchase invoice with duty and vat?

Hello Agnes6, Welcome to the Community page, 

do you want to account for the whole expense or just the duty (vat)?

if only  the disbursement and duty then put the expense in for that to to either no vat or 00.0 rates or  exempt confirm with  accountant and then do a 100% vat expense to account for all of the vat

1. In your QuickBooks Online (QBO), click the + New button and select Expense.
2. Choose the vendor (HMRC) in the Payee drop-down.
3. Enter the payment date the amount was debited from your account.
4. In the Amounts are drop-down, select Exclusive of Tax.
5. Select purchases or another expense account from the Category column.
6. Enter 0.01 in the Amount column, then select 20.0% S from the VAT column.
7. On the second line, use the same expense category and enter -0.01 in the Amount column.
8. Select Exempt or No VAT from the VAT column.
9. Then, enter an amount in the VAT box and Save and close.

Once done, it'll help you create a 100% VAT transaction.

It's a tricky one you can do it on all one transaction and put the  100% vat transaction at the bottom of the expense. We would advise you confirm this all with an accountant.
