Based on the details provided, you’ll no longer have to add the amounts. QBO allows you to create a partial payment for the invoice. All you have to do is apply each one to the transaction.
Here’s how:
- Tap the Banking menu to select the Banking tab.
- From the list, pick the account you’re working on.
- In the For Review column, click your mouse to the payment to expand the line.

- Tick the radio-button for Find Match to open the Select transactions to match page.
- Hover your mouse to the invoice and enter the partial amount in the Payment box.

- Click Save.
- Perform the same procedure to the remaining amount you want to match.
