Hello, @Malama.
If you wanted to delete Unapplied Payment individually, you need first to split the payment.
Here’s how.
- At the top, click the Create menu (+) and select Receive Payment.
- Select the customer name and enter the Payment date.
- Enter Undeposited Funds in the Deposit to the field.
- Select the invoice you want to pay and click Save and close.
- Do this to the other invoices you want to include in the deposit.
Once done.
- Select the Unapplied Payment.
- Click More.
- Then, select Delete.
