I've to create a Spare Part management and ecommerce store using odoo17 It should have 4 roles type:

Manufacturer

Distributor

Customer

and Platform admin to onboard Distributor and Manufacturer

All these roles have here username password i.e. credentials to login and have different functionalities

Both manufacturer and distributor have list of stocks which detailed on incoming and outgoing units and etc. info

Order can be made to Manufacturer from distributor and Manufacturer has functionalitites to accept and reject the order

Manufacture should have list of end customers as well as distributors where orders have been placed

Manufacture should be able to generate and alert in case they plan to stop the production of some part such that early orders can be placed before it happens. These alert should be automated mails based on parts.

The process to get parts should be something like request for RFQ→ Quotation → PO → Shipment(invoice)

There should be operation manual attached with every product when client sees it
