WooCommerce One Page Checkout

I purchased Yith Customize my account to be able to add custom endpoints. I added My Files using the Woo File Upload plugin. I can add the product to the dashboard page using the shortcode, but I can’t complete the purchase process on the same page. If it’s possible, I don’t know how.

I wanted to add 1 product to my account dashboard and complete the entire add to cart and checkout process on that same page without needing the billing information. The product being purchased can only be purchased by paid clients that already have an account. The product I am referring to is the File Upload product which is free to ONLY clients.
