Hello Odoo Community,

I am looking to implement the following features in the Odoo Purchase module:

1. Vendor Penalties for delayed deliveries, including automatic penalty application based on terms.
2. Payment Process Automation, linking purchase orders, invoices, and payments, with options for discounts and late fees.
3. Maker-Checker Roles across all stages of the purchase module to ensure approval before actions are finalized.

Any suggestions, best practices, or existing modules to achieve this would be greatly appreciated.

Thank you!
