You're most welcome, @HollyJ!

I've got some insights about the Resolve difference feature in QuickBooks Online (QBO).

There may be times when a bank item amount (payments/bank fees) doesn't quite match the transaction you entered (invoice). When you go to the Banking page, they don't add up even though they're the same entries.

In this case, you can use the Resolve difference feature to match them and fix the payment differences until it equals to zero. 

Let me guide you on how to perform this task:

1. Go to the Banking menu, and then choose the For Review tab.
2. Find the said transactions, and then select the Find match button to open the Match transactions window.
3. Look for and select the invoice payments to match. You can also use the filters to narrow down your search.
4. Scroll to the bottom of the table, and then click the Resolve Difference button.
5. Enter the processing fee details. Make sure the total is zero.
6. Click Save when you're ready.
