A customer paid half now and will pay the rest later. How do I record each payment?

With the Partial Payments plugin, every order page has a Payments box showing Total, Paid and Balance due.

Each time money comes in:

1. Open the order and click Record payment.
2. Enter the Amount received.
3. Choose the Method: Cash / other, Bank transfer, UPI, Card / online or Wallet.
4. Optionally add a Reference (transaction ID or cheque number) and a Note.
5. Click Record payment.

You can't record more than the balance due. When the balance reaches zero, Wcart shows "order fully paid", and the button greys out.
