Pre-order Timing

Hi,

Please tell me which preorder plugin you’re using. I can help you check this plugin and find out the solution.

No any additional plugin. I am asking to change the state unpurchasable to preorder

Do you just want to change the “Add to cart” button to “Pre Order”, it works as same as the normal add-to-cart button?

As I know, preorder is a special state and have many differences on the cart/checkout page https://woocommerce.com/products/woocommerce-pre-orders/
