We invoice 100 pounds but receive only 90 because of bank charges. How can we offset the bank charges using the 'match' option in the "Bank transaction" window?

Thank you for reaching out to the Community, Mostro.

I'd be glad to help you offset the bank charges using the match option in the bank transaction window of QuickBooks Online (QBO).

You can use the Resolve Difference feature for you to offset the bank charges using the match option. To do so, follow the steps below:

1. Go to the left navigation panel and select Transactions.
2. Select Bank transactions and choose the For Review tab.
3. Find the said transactions and then select the Match or Find match button to open the match transactions window.
4. Look for and select the invoice payments to match.
5. Scroll to the bottom of the table and then click the Resolve Difference button.
6. Filter the date, payee and select a category or account. (You can refer to your accountant on what account to use).
7. Enter the bank charges in the amount section.
8. Once done, select Match.
