Hello,

I've an invoice Inv01(total amount of 100 USD for example) which is paid and my client has returned some goods, so i've created a refund (total amount 40 USD) for the invoice inv01. Now my client seems to be paying me 60 USD and i still owe him 40 USD.

after this, we had a new transaction and i gave my client a new invoice Inv02 to pay (let's say 150 USD of total amount).

My question is: how can i get the latest invoice Inv02 paid using the refund of the Inv01 invoice? meaning: get the total amount of Inv02 be like: 150-40 USD.
thanks in advance
