Hi Maria,

I'm afraid that we do not have any built-in option for this in the plugin.

I think the easiest way you might achieve it, is maybe through a WP CRON JOB, that is registered using the hook 'woocommerce_created_customer'. It could be set so that after 1 year, it sets the user role to 'customer' and the B2BKing user group to B2C.

In principle, I think a code snippet such as this one could work:

add_action('woocommerce_created_customer', 'schedule_customer_role_change', 10, 1);
function schedule_customer_role_change($customer_id) {
    // Schedule an event to run one year from the registration
    if (!wp_next_scheduled('change_customer_role_one_year', array($customer_id))) {
        wp_schedule_single_event(time() + YEAR_IN_SECONDS, 'change_customer_role_one_year', array($customer_id));
    }
}
// Add the custom action hook
add_action('change_customer_role_one_year', 'change_customer_role_and_meta', 10, 1);
function change_customer_role_and_meta($customer_id) {
    // Get the user object
    $user = new WP_User($customer_id);
    // Check if the user exists
    if ($user->exists()) {
        // Set the user role to 'customer'
        $user->set_role('customer');
        // Update user meta keys
        update_user_meta($customer_id, 'b2bking_b2buser', 'no');
        update_user_meta($customer_id, 'b2bking_customergroup', 'no');
    }
}
// Ensure cleanup of scheduled events if user is deleted
add_action('delete_user', 'cleanup_scheduled_events');
function cleanup_scheduled_events($user_id) {
    // Get all scheduled events for the user
    $timestamp = wp_next_scheduled('change_customer_role_one_year', array($user_id));
    if ($timestamp) {
        wp_unschedule_event($timestamp, 'change_customer_role_one_year', array($user_id));
    }
}

Kind regards,

Stefan
