I was wondering if anybody had this challenge, to sell a product that will be paid over time. 

Example:

Sell a widget, for $300, which will be paid over 12 months at $25 per month. 

Ideal Solution: It would be great to be able to create a Sales Order for the Widget, possibly including 12 qty of an "installment item" and create an invoice each month for each "installment item".

I found many "Accounting Best Practices" and I would like to know if there is an "easy-enough" way of implementing this in Zoho Books.

Thanks!
