Credit Note for my Buyer

My seller returned some goods and we agreed that there is no need for the refund in money - he wants credit note for that amount.

When I will create one and then would like to use it partially as a payment for his next sales invoice how do I do it?

Will CN create credit on his account and I just use his balance as a payment method?

Thank you

Take a look here (there’s a specific option to hold the balance on account):
