Create Dashboard for Customers to order and see the order progress (can be through a no-code app)

Basically I want to add to my website a dashboard where people will be able to place their order, pay, track the order process etc. and add it to my website. So it would have to be app.mywebsite.com basically, completely different from my landing page.

We are selling Google Workspace Emails, so they would be ordering emails and domains, that’s it.

I just need a simple dashboard where people could sign in, place an order for 10 domains and 20 emails for example, write what domains they need, then what users they need created for those domains, then pay and wait for us to process the order.
