When purchasing products from your store, you require information from your customer. Perhaps you run a t-shirt printing company, and you require the customer to enter in the text they would like to have printed on the t-shirt.
For this, you can add a simple text input field to your product listing, and charge an extra fee, using the Ninja Forms Product Add-ons extension for WooCommerce.

The Sort | Hide Out-of-Stock plugin for WooCommerce helps you maintain a clean, shopper-friendly storefront by automatically hiding or rearranging unavailable products. You can choose to completely remove out-of-stock items from your store, push them to the bottom of product listings, or sort them however you prefer—either storewide or within specific categories and tags.
Once products are restocked, they reappear automatically, ensuring your catalog stays up to date without manual work. Advanced features like role-based visibility, custom redirects from unavailable product pages, and a detailed hidden-stock report give you complete control over how out-of-stock products are handled.
