Yes, Webkul’s WooCommerce Pre Order Plugin can support grouped products. Many pre-order plugins let you sell multiple related products together before they are in stock. You can set each product in the group for pre-order, choose payment options, and add an estimated delivery date. Make sure your plugin supports grouped products by checking its documentation or settings. Always test with a sample grouped product before going live. This ensures pre-orders work smoothly for your customers and avoids potential issues with stock or payment processing.
