Hi everyone, 

We are an IT company that would like to use Odoo V9 to generate monthly bills.

The module Subscriptions seems perfect but we are stuck on 1 thing to validate Odoo as the good product for us :

• We want to send 1 invoice per customer per month only. Not more than 1 (very important for us)

• We have some products with 3 year contrats, or 1, or some times, not even an end date

So I see 2 possibilities : 

• Is there a simple way to merge multiple contracts on 1 invoice each month ?

• Is it possible to have different end date per element on the same contract ?

Thanks in advance for your help,
