Hello community!

I’m looking for guidance on managing specific scenarios related to purchases and invoicing in Odoo. I have suppliers who handle different invoicing periods for products like licenses or subscriptions: some issue monthly invoices, while others issue annual invoices for the same products or services. What’s the best way to configure and manage this in Odoo's purchase module?

Additionally, I need to know if it’s possible to associate multiple vendors bills from the same supplier with a single Purchase Order (PO) and how to correctly handle this process.

Lastly, I have cases where the payment dates for invoices linked to certain POs are split, with part due in the same year and the rest in subsequent years. I’d like to understand how to account for these operations in Odoo and, if possible, have someone share a practical example or step-by-step guide to implement it.

I greatly appreciate any advice, tips, or experiences you can share!

Thank you!
