How to Add a Prefix/Suffix to B2B / B2C Order Numbers or Split B2B / B2C Orders

By default, B2BKing adds a B2B column to the Orders page, making it easy to identify which orders are B2B:

Note: For this to work, the plugin must be set to "B2B & B2C Hybrid Shop" in B2BKing -> Settings -> Main Settings.

However, you may also want to change the order numbers. Here's what you need to know.

Change Order Number #

You may want to differentiate between B2B and B2C orders via the order number if you are running a hybrid site. Here is a simple code snippet that can do it.

// Add Prefix to Orders by B2B
add_filter( 'woocommerce_order_number', 'change_woocommerce_order_number' );

function change_woocommerce_order_number( $order_id ) {
    // get if customer is B2B
    $order = wc_get_order($order_id);
    if ($order){

        // Check if the order is a refund object
        if (is_a($order, 'WC_Order_Refund')) {
            return $order_id;
        }
    
        $customer_id = $order->get_customer_id();
        $customer_b2b = get_user_meta($customer_id,'b2bking_b2buser', true);
        if ($customer_b2b === 'yes'){
            $prefix = 'PRO-';
                $suffix = '';
            $order_id = $prefix . $order_id . $suffix;
        }
    }
    
    return $order_id;
}

This code adds "PRO-" to all orders placed by B2B customers.

Here's what that looks like in practice in the backend:

This is a simple way to differentiate between orders, and it can be useful in many scenarios, especially for delivery and order fulfillment.
