Online payment for an order in WooCommerce after moderation - ready-made solutions (plugins)?

Question

WordPress

The WooCommerce online store requires the following payment algorithm:
1) The buyer, as usual, places an order on the site, but does not pay anything
2) The manager processes the order and sets the order status, for example: "Waiting for payment"
3) The buyer receives an E-mail- notification with a link, by clicking on which he proceeds to pay for his order.
I understand that you can do everything yourself - but as usual, suddenly tell me a ready-made (even paid) solution that will save time?

Answer 1

Everything turned out to be quite simple:
For example, you can do this:

function receipt_page($order_id) {

      	global $woocommerce;
      	$this->order = new WC_Order($order_id);

      // если заказ не помечен как готовый к оплате, то меняем статус на "Обработка" и перекидываем на страницу с уведомлением! 
      if (get_post_meta( $this->order->id, 'ready_to_pay', true) != 1) {
      		$woocommerce->cart->empty_cart();
      		$this->order->update_status('processing');
      		wp_redirect( home_url( '/' ) ); // заменить на URL-адрес страницы с текстом: "Ваш заказ поступил в обработку..."
        return false;
      	}

and then if the order status changes to "Awaiting payment", then:

add_action( 'woocommerce_order_status_pending', function ($order_id) {
  update_post_meta( $order_id, 'ready_to_pay', 1);
});

The plugin allows you to create your own custom statuses (Pending Payment in your case) and change the process (that is, the order of transitions between statuses).
