Regarding partial payment of an invoice which I want to add in next invoice and send to the customer

Hi,

I just have started using Zoho Books from yesterday, so apology for naive question!!

I provide monthly payment based software service. Lets say that I have created an invoice for a customer xxx of $1000. But the customer has paid $900. Is there any way that I can add this due amount to the next month invoice I create so my customer can see his previous due and pay?

I can understand I cannot add this to the invoice manually since it will be then double counted. Please suggest.

Regards
