Want to create a Booking, Rental, or Gift Card product in WooCommerce without relying on bloated third-party plugins? You’re in the right place.

In this tutorial, we’ll walk through how to add a completely custom product type in WooCommerce — using native hooks, classes, and filters.

This is a powerful technique used in real-world plugins like:

• Booking plugins (bookable)
• Gift card tools (giftcard)
• Rental product managers (rental)

What We’ll Build

We’ll create a new product type called Rental Product. It will:

• Appear in the admin “Product Data” dropdown
• Show only when selected
• Use a custom pricing field (e.g., price per day)

Step 1: Register the Product Type

Add this to your custom plugin or theme functions.php:

add_filter( 'product_type_selector', 'custom_add_rental_product_type' );
function custom_add_rental_product_type( $types ) {
    $types['rental'] = __( 'Rental Product', 'your-textdomain' );
    return $types;
}

Now, in the admin product edit screen, you’ll see “Rental Product” as an option.

Step 2: Extend the WC_Product Class

WooCommerce needs to know what a rental product does.

Create a new class:

class WC_Product_Rental extends WC_Product {

    public function get_type() {
        return 'rental';
    }

    public function get_price_per_day() {
        return $this->get_meta( '_price_per_day' );
    }

    public function set_price_per_day( $value ) {
        $this->update_meta_data( '_price_per_day', $value );
    }
}

Then tell WooCommerce about this custom type:

add_filter( 'woocommerce_product_class', 'custom_rental_product_class', 10, 2 );
function custom_rental_product_class( $classname, $product_type ) {
    if ( $product_type === 'rental' ) {
        $classname = 'WC_Product_Rental';
    }
    return $classname;
}

Step 3: Add Custom Fields in Admin

Use WooCommerce’s woocommerce_product_options_general_product_data action:

add_action( 'woocommerce_product_options_general_product_data', 'custom_rental_product_fields' );
function custom_rental_product_fields() {
    global $product_object;

    if ( $product_object && $product_object->get_type() !== 'rental' ) return;

    woocommerce_wp_text_input( array(
        'id'          => '_price_per_day',
        'label'       => __( 'Price Per Day', 'your-textdomain' ),
        'desc_tip'    => true,
        'description' => __( 'Enter the price per day for rental.', 'your-textdomain' ),
        'type'        => 'number',
        'custom_attributes' => array(
            'step' => '0.01',
            'min'  => '0',
        ),
    ) );
}

And save the data:

add_action( 'woocommerce_process_product_meta', 'custom_save_rental_product_fields' );
function custom_save_rental_product_fields( $post_id ) {
    if ( isset( $_POST['_price_per_day'] ) ) {
        update_post_meta( $post_id, '_price_per_day', wc_clean( $_POST['_price_per_day'] ) );
    }
}

Step 4: Adjust Visibility of Tabs and Fields

Some default WooCommerce tabs (like shipping) may not apply. Use:

add_filter( 'woocommerce_product_data_tabs', 'custom_hide_tabs_for_rental' );
function custom_hide_tabs_for_rental( $tabs ) {
    global $post;

    $product_type = get_post_meta( $post->ID, '_product_type', true );
    if ( $product_type === 'rental' ) {
        unset( $tabs['shipping'] );
    }

    return $tabs;
}

Bonus: Show Custom Price on Frontend

If you want to display “₹500 per day” instead of the regular price:

add_filter( 'woocommerce_get_price_html', 'custom_rental_price_html', 10, 2 );
function custom_rental_price_html( $price, $product ) {
    if ( $product->get_type() === 'rental' ) {
        $per_day = $product->get_price_per_day();
        return wc_price( $per_day ) . ' ' . __( 'per day', 'your-textdomain' );
    }
    return $price;
}

Final Result

Now your WooCommerce store supports an entirely new product type with custom logic — perfect for plugins like:
