manual over payment in invoice, mark invoice paid + full credit

[ghpk]

A client ordered some services which was billed raising a manual invoice.

Client Paid via cheque, but mistakenly paid extra.

Invoice was amount 400

payment Added from add payment tab under invoice page amount 500

invoice was mark paid as soon as payment was posted,

still the client has amount 500 as available balance.

 

Can anyone check and suggest ?

I've had a couple of overpayment here. The Available Credit shows up as the amount of the overpayment, so it seems to be working for me.
