Hi Odoo community,

I’m managing a beauty spa, and we’re using the Appointment module to allow clients to book services. We have a payment policy that requires clients to pay 50% upfront when they book the appointment and the remaining 50% after the service is completed.

Here’s what we need:

1. When a client selects a service (e.g., a makeup session or nail treatment) from the inventory during the appointment booking process, they should proceed to make an upfront payment of 50% of the total service cost.
2. After the service is completed, the client would then be charged the remaining 50%.

Is there a way to implement this workflow directly within the Appointment module or any integrations that would allow this functionality? If not, are there any workarounds or customizations that can be done to enable partial payments in the booking process?

Looking forward to any advice or solutions. Thanks in advance!
