RFQ System Workflow Suggestion Needed (Laravel Project)

Hi everyone, I'm building an RFQ (Request for Quotation) system in Laravel. I'm still finalizing the workflow and need some advice. Here's the basic flow I'm planning:

Client submits an RFQ.

Admin reviews the request.

Admin assigns it to a contractor/supplier.

Contractor submits quote:

Either directly to the client, or

First to the admin for review and then forwarded to the client.

I'd appreciate any feedback or suggestions to improve this workflow or handle edge cases.

Thanks!
