Customer Portal Instruction help needed


I am tying to create a website user for my customer. I want my client to view projects associated to them, View quotes, Sales order and Sales Invoice.

Steps already done.

  1. Created the customer.
  2. Created the website user as an admin. ( When using signup method it stays stuck on verifying.)

Problems currently facing.
When I log in as the client no projects show up. It goes to the desk but has a 404 landing page.

How to?
How do I enable them to see there invoice and sales orders


The only thing I am able to do for now is create a user as an admin.
