This plugin allows you to designate certain products in your WooCommerce store to have no price. Instead, it displays a configurable button for customers to request a quote directly via a chat app (like WhatsApp).
From the settings page, you can customize: 
* The WhatsApp phone number. 
* The button text and icon. 
* The predefined message the customer will send. 
* The button colors.

Quote via Chat Button

Replaces the "Add to Cart" button with a chat button for products without a price, with customization options.
