Can anyone explain how the Credit Note function works in Zoho Invoice?  I recieved an early monthly payment from a customer before their monthly Recurring Invoice was emailed out.  I entered this early payment as a Credit Note to that Customer when I received it.  I was thinking that when their invoice was generated, it would see that a credit had been issued to their account and give it a zero balance.  However, the invoice went out with the normal monthly amount due??  Why didn't Zoho Invoice see that this customer had a credit and apply it to the invoice before it was sent out?

 

Please help!
