Hello,

I'm having an issue that I don't know if the simple way is the correct way.

I have a vendor that is also a customer.

Due to some issues in the past, he didn't pay some invoices. Now we agreed that he will pay its debt by giving us a 10% discount on the next purchases from him until it covers the balance.

But I don't how could I use the discount given in the bills to cover the open invoices, I was thinking that a credit memo would solve it, but I think I'm missing something.

could someone help, please?

Thanks
