A: Hi,
Yes, absolutely, you can do this without building out a full store.
The setup is simple:

Add your products
Set up your payment provider (so checkout can accept payments)
Use Nova AI to generate the product pages simple or complex as per your need and checkout flow for you

You don't need to design a full storefront, theme, or navigation. Just create the product, connect a payment method, and Nova can spin up the page and checkout is already optimized out of the box for you to start accepting payments.
