Invoice write-off balance after partial payment

Hello,
I have sent an invoice to customer, but customer negotiated a discount and may payment to the bank. Please how do I write off the different.
Example Customer was issue a $100 invoice, but after further negotiation with the business, customer now paid $80. How do I write off the balance, so the Invoice show paid and not overdue.

Pass a Journal Entry to write off the invoice.
