I am on Odoo v15 I have a sale ordre of 65 days (invoicing method according to delivery products) of service for a duration of 3 months (january, february, march). I want to charge the customer for each month. Like my employee did 22 days in January (invoice 1) , 20 days in February (invoice 2) and 18 days in March (invoice 3)
