To use eCommerce Product Catalog without prices, go to Products > Settings > General Settings and find the Payment and currency section. Set the Price option to Off and save the settings.
Now the price is disabled for the whole catalog. The price field is removed from the product edit screen, and prices are not shown on product pages or listings. The price column is also skipped in the CSV import and export, and no product structured data is added, because it requires a price.
You can also switch the price off in the Disable Price option of the theme integration wizard.
This way eCommerce Product Catalog can work without prices without any loss in performance, and you can still use most of the extensions.
Hide the price for some products only
To hide the price only for selected products, keep the Price option on and leave the price field empty on those products. A product with an empty price shows no price box.
Which catalog mode to use without prices
If you don’t show prices, choose the Simple Catalog or Inquiry Catalog mode in the Catalog Mode section. In Inquiry Catalog mode, visitors can still add products without a price to the inquiry cart and send you a quote request. See catalog modes and catalog without shopping cart.
To turn prices back on, set the Price option to On and set your catalog currency.
