The “Customer invoice/ Order details” WooCommerce email notification template is used manually by store owners when sending payment requests to customers. This email template is a perfect choice for sending pending payment reminders as well.
In this post, we will use the Customer invoice/ Order detail email template to send WooCommerce automatic payment reminder notifications. To make it a bit smarter, we will make the reminder email triggered automatically when the order status transitions to “pending payment”.
Solution: Send Email for Pending Payment Status
You can automatically send a pending order email to customers when their WooCommerce order status changes to “Pending Payment” by using the WooCommerce Customer Invoice email template and a simple code snippet.
add_action( 'woocommerce_order_status_pending', 'ts_send_pending_order_email', 10, 2 );
add_action( 'woocommerce_new_order', 'ts_send_pending_order_email', 20, 2 );
function ts_send_pending_order_email( $order_id, $order ) {
if ( ! $order instanceof WC_Order ) {
$order = wc_get_order( $order_id );
}
if ( ! $order || $order->get_status() !== 'pending' || ! $order->needs_payment() ) {
return;
}
// Get WooCommerce mailer and the Customer Invoice email object
$mailer = WC()->mailer();
$email = $mailer->emails['WC_Email_Customer_Invoice'];
// Trigger the email
$email->trigger( $order_id );
// Add an order note for reference
$order->add_order_note( 'Payment reminder email sent automatically for Pending Payment order.' );
}
Output
Whenever the order status is changed to ‘pending payment’, the customer invoice email is triggered and will be sent to the customer’s email notifications, as shown below.
Alternatively, if you want to keep the site admins in the loop, you can send processing order email to admin email notifications. This helps the admin to track the processing stage of the order.
Hello, thank you, it’s work.
How to edit email pending payment? I want to add “Pay for this order” below to payment method.
Thank you
Hi Yeti, The code snippet in this blog post is only responsible for sending the Pending Payment (Customer Invoice) email automatically when the order status changes to Pending payment. It does not control the content or layout of the email itself. To add the payment link inside the Order Details table, directly below the Payment Method, add the following snippet in addition to the one already present in the blog post: add_filter( 'woocommerce_get_order_item_totals', 'ts_add_pay_link_below_payment_method_in_email', 20, 3 ); function ts_add_pay_link_below_payment_method_in_email( $total_rows, $order, $tax_display ) { // Only pending payment orders if ( ! $order || $order->get_status() !== 'pending' || ! $order->needs_payment()… Read more »
Thank you very much
You’re welcome
Thanks for the article. It looks exactly like the function that I am looking for as there are several Payment Pending orders appeared in my webstore. I copy and pasted the function in the child theme’s functions.php. I tested the function with a new order created at the backend with the order status set to “pending payment”. I click create order but no reminder email is sent. Am I missing something? does the function required any plugin other than Woocommerce?
Hi Elton,
The original snippet only works when there is a “status transition” happening (like from On hold to Pending). But when you create a new order and set it to pending right away, there’s no status transition, so the hook never fires. That’s why the email isn’t sent in that case. We’ve updated the code in the blog post by adding the woocommerce_new_order hook and using WooCommerce’s proper email trigger method so it works for both scenarios.
I am very happy to let you know the script works very well. Reminder email sent both for new Payment Pending order and order that switched into Payment Pending.
I hope it will catch a few leaked customers that have a order with a failed paypal transection (it happens a lot these few days)
Hi Elton,
That’s great to hear!
Hi, thanks for this solution. Does this also work for new orders that are automatically set to ‘pending payment’ at the checkout? For my product, customers need to download the invoice BEFORE paying (they send it to their finance department who then pays via bank transfer).
Hi Ruby,
Yes, this solution will also work for new orders that are automatically set to ‘pending payment’ at checkout. However, since you mentioned that the customer pays via the Bank Transfer payment method, the default order status will be set to ‘on-hold’. In this case, you’ll need to update the hook to woocommerce_order_status_on-hold instead.
Thanks Saranya, I will try that. I’m not too familiar with coding in WordPress, would you mind telling me where to insert that code component? Thank you!
Hi Ruby, You can place the code either in your child theme’s functions.php file or use a plugin like Code Snippets, which makes it easy to add custom code solutions. You can use the code below, which automatically sends an invoice email for orders set to ‘on-hold’ status. // Trigger the invoice email for orders that are set to on-hold after checkout add_action( 'woocommerce_order_status_on-hold', 'ts_send_invoice_email_for_on_hold_orders', 10, 1 ); function ts_send_invoice_email_for_on_hold_orders( $order_id ) { // Retrieve the order object using the order ID $order = wc_get_order( $order_id ); // Ensure the order is valid and has 'on-hold' status if ( $order… Read more »
