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.
