This plugin allows you to use the power of WooCommerce to manage all your products whilst hiding the eCommerce functionality like the Add to Cart Buttons, Prices, Ratings and the Cart & Checkout pages from your customers.
Later on, when you decide you’re ready to sell your products online, simply disable this plugin and all your WooCommerce functionality will return.
