WooCommerce Waitlist is a plugin that allows customers to join a waitlist for out-of-stock products on a WooCommerce store. This plugin can help store owners to better manage product inventory, reduce frustration for customers who are interested in purchasing a product that is currently out of stock, and increase sales by notifying customers when the product is back in stock.

Customers can easily join a waiting list via a button on the product listing of the WooCommerce store. As soon as the stock numbers for a product are updated on the site, everyone on the list automatically gets an email with a link to the product, making it super simple for them to buy.

WooCommerce Waitlist fully supports simple products, product variations, and the children of grouped products. Shop managers can sort products by the number of customers on their waiting list, allowing them to quickly prioritize which products to re-stock.

Shop managers can also view, manage, and contact those on the waiting list for each product directly from the Edit Product screen through a custom product tab.

It is easy to add or remove users from the waiting list, see archived lists, export a CSV of users on a waiting list/archive, and adjust the waiting list options for this product.

Customers can view any products they have joined the waiting list for on the “Your Waitlists” tab on their “My Account” page. This allows users to conveniently manage all their waiting lists in one place.

WooCommerce Waitlist comes with plenty of options for store owners to get the most from the plugin, including options to display opt-in elements when users sign up to a waitlist, options to also display waitlist buttons on archive pages (e.g. the shop page/product category pages), options to add Google Analytics tracking codes to WooCommerce Waitlist emails, options to email a site administrator when a customer joins a waitlist, options to set a minimum stock before WooCommerce Waitlist in-stock notifications are sent out, and more.

The default setup of WooCommerce Waitlist is ‘plug-and-play’ but the plugin adds a large number of WordPress action and filter hooks allowing store owners to customize it to suit their exact needs.

Customizations include choosing the wording for notification emails, tweaking the design of ‘join waiting list’ buttons, hooking in extra functionality when users are added to/removed from a waiting list, altering the design of the “Your Waitlists” page added to the “My Account” section.

WooCommerce Waitlist is also compatible with other extensions like WooCommerce Subscriptions, WPML (The WordPress Multilingual Plugin), The Events Calendar (from ModernTribe), and WooCommerce Product Bundles.

Overall, WooCommerce Waitlist is an effective and easy-to-use plugin that helps store owners manage their product inventory and increase sales by notifying customers when a previously out-of-stock product becomes available for purchase.
