How to Allow Registered Customers to Skip Cart and Checkout and Place an Order?

To allow registered customers to skip cart and checkout and place an order with a single click from the product page using the WooCommerce Quick | Instant Order Plugin, you can follow these steps:

First, make sure you have the WooCommerce Quick | Instant Order Plugin installed and activated on your WordPress website.

After activation, go to your WordPress admin dashboard, and in the left sidebar, click on “Instant Purchase” in the WordPress Admin Panel. Configure the plugin setting by entering a customized Instant Purchase button text. 

Only registered customers who have purchased previously from your store will see this button. 

When the customers click on this button, a popup will appear displaying the complete order information. 

Customers can just click the “Place Order” button to make the purchase.
