This module is built for you if:

• Customers can enter the amount they want to pay, and the remaining balance updates automatically.
• You need the Amount Due column to show outstanding balance that is yet to be paid by the customer with paid amount, payment date, and balance shown on hover.
• You want invoice status to auto-update between Unpaid, Partially Paid, and Paid, along with a payment progress percentage and a Pay Now option.
• You need a one-click "Reminder Set" button that emails the customer their remaining balance with the message "Balance is still pending."
• You want a Pay Pending screen that lists only Unpaid and Partially Paid invoices, with checkboxes and a running total of the selected balances.
• You need customers to be guided with a clear warning if they try to pay without selecting an invoice, and a read-only confirmation amount in the payment wizard before the payment goes through.
