function create_wholesale_customer_role() {
    add_role(
        'wholesale_customer',
        __('Wholesale Customer'),
        array(
            'read'         => true,
            'edit_posts'   => false,
            'delete_posts' => false,
        )
    );
}
add_action('init', 'create_wholesale_customer_role');

// Apply different discounts for specific categories
if (has_term('electronics', 'product_cat', $product->get_id())) {

} else {
    $discount = 25; // 25% off everything else
}
