Hey Odoo Community,

I'm currently working on setting up my invoicing process in Odoo 17 "CE" and could use some guidance. I offer a service that is sold on an annual basis, with the total price decreasing by a certain percentage each month over the course of the year. What I'm aiming for is to have Odoo automatically generate invoices for this service on a monthly basis, with each invoice reflecting the reduced price for that particular month.

To give a clearer picture, let's say I sell a service for one year at $1200, and I want to bill the customer $100 per month. However, I'd like Odoo to handle this automatically, deducting the appropriate percentage from the total price each month.

Could someone please walk me through the steps to configure Odoo 17 to achieve this? Ideally, I'm looking for a solution that can be implemented through the UI interface.

Thanks in advance for any help or suggestions you can provide!
