If you want to enable Pre-Orders across all products, updating each product individually can be time-consuming. Fortunately, the PreCart plugin allows you to activate pre-orders for all products with just a few clicks.
Steps:
Navigate to PreCart > General Settings in your WordPress admin menu.
Locate the Enable Pre-Order switch and turn it on.
Set a Pre-Order Release Date to indicate when the products will become available.
That’s it! Pre-orders are now enabled for all products in your store.
All products will now display as available for pre-order until the specified release date.
