Instant Chat Checkout adds WhatsApp checkout for WooCommerce stores while still creating normal WooCommerce orders. Customers can start an order from a product page or checkout, send the order details to your WhatsApp number, and leave you with a trackable WooCommerce order in the admin.
Use it when your store sells through WhatsApp, phone follow-up, local delivery, pickup, or cash-on-delivery workflows and you want more structure than a basic chat button.
Key features:
<ul>
<li>WhatsApp checkout payment gateway for WooCommerce.</li>
<li>Product-page “Order on WhatsApp” button and quick order modal.</li>
<li>Customer name, phone, email, country, region, address, quantity, and shipping fields.</li>
<li>Shipping-aware order estimates that follow WooCommerce shipping setup.</li>
<li>Team routing modes: single, round robin, and region/state routing.</li>
<li>Free-shipping area controls driven by WooCommerce country/state settings.</li>
<li>Google Analytics compatible tracking (<code>gtag</code> and/or <code>dataLayer</code>).</li>
<li>Thank-you page WhatsApp handoff link.</li>
<li>Admin dashboard snapshot for WhatsApp order activity.</li>
</ul>
Good fit for:
<ul>
<li>Fashion, beauty, food, grocery, pharmacy, and local retail stores.</li>
<li>Stores that confirm availability, delivery fees, or payment manually before dispatch.</li>
<li>Stores that use WhatsApp as the main sales conversation channel.</li>
<li>Cash-on-delivery, bank transfer, mobile money, local pickup, and assisted checkout flows.</li>
<li>Teams that need to route orders to different WhatsApp numbers by region or rotation.</li>
</ul>
Why use this instead of a normal WhatsApp chat button?
<ul>
<li>A normal chat button starts a conversation but does not structure the order.</li>
<li>Instant Chat Checkout collects customer and delivery details before the WhatsApp handoff.</li>
<li>The plugin creates a WooCommerce order, so store admins can still track order status, totals, and customer details.</li>
<li>The WhatsApp message includes the order summary, customer details, and destination number.</li>
</ul>
This plugin is distributed under GPLv2 or later.

This plugin adds the option for a minimum order amount, as well as the option change the notification text for the cart page. Customers can’t proceed to checkout if the order doesn’t meet the minimum order amount.
