drupalcommerce as product catalog

Hello, I'm new to drupal commerce.
I need to do something particular.
I'm developing a new site for a company.
They want to show their products in a catalog with the future possibility to transform it in an online shop.
So I would like to build the site with drupal commerce like it was drupal 7 so I need to disable all commerce modules and be able to make product price not mandatory.
Is possible to do that?
I'm just a fool?
