How to Add a Custom Shipping Method for WooCommerce

In this tutorial, I’ll walk you through the process of adding a new shipping method to WooCommerce using custom code. By the end of this tutorial, you will have a working shipping method that can be configured directly from the WooCommerce settings.

Create a Custom Shipping Class

WooCommerce relies on classes to define shipping methods. Let’s create a new class for our custom shipping method.

[cc lang="php" tab_size="2" lines="40"]
// Add a custom shipping method
function add_custom_shipping_method( $methods ) {
    $methods['custom_shipping'] = 'WC_Custom_Shipping_Method';
    return $methods;
}
add_filter( 'woocommerce_shipping_methods', 'add_custom_shipping_method' );

// Define the custom shipping method class
class WC_Custom_Shipping_Method extends WC_Shipping_Method {

    public function __construct() {
        $this->id = 'custom_shipping';
        $this->method_title = __( 'Custom Shipping', 'woocommerce' );
        $this->method_description = __( 'A custom shipping method example.', 'woocommerce' );

        $this->enabled = "yes";
        $this->title = "Custom Shipping";

        $this->init();
    }

    public function init() {
        // Load settings
        $this->init_form_fields();
        $this->init_settings();

        // Save settings
        add_action( 'woocommerce_update_options_shipping_' . $this->id, array( $this, 'process_admin_options' ) );
    }

    public function calculate_shipping( $package = array() ) {
        $rate = array(
            'id' => $this->id,
            'label' => $this->title,
            'cost' => '10.00', // Flat rate shipping cost
            'calc_tax' => 'per_order',
        );
        $this->add_rate( $rate );
    }
}
[/cc]

Lastly, go to WooCommerce > Settings > Shipping and configure the new shipping method as you need.
