The discussion centers on automating payment reminders for unpaid orders in Shopify, specifically for customers using bank transfer or purchase order payment methodsânot abandoned carts.
Initial Problem:
Users wanted to send automated payment reminders to customers with pending payments but found Shopify Flow could only send emails to staff, not customers.
Solution Evolution:
Early responses suggested third-party apps like Avada Email Marketing and Kindly Payment Reminder
Shopify later implemented native payment reminder functionality through Settings > Notifications > Payment Reminders
This feature requires setting payment terms with due dates on orders
Key Implementation Details:
For existing orders: Edit payment terms to add a due date
For draft orders: Select âpayment due laterâ and add payment terms directly
Reminders automatically send on/after the due date when configured
Current Challenges:
Some users report reminders not sending despite proper setup
Request for separate accounts payable email field (currently reminders only go to customer email)
Users seeking pre-due-date reminders (e.g., 7 and 14 days before) may need Shopify Flow workarounds or third-party apps
One user successfully configured reminders using Flow, though specific implementation details werenât shared.

I want to build a flow to send out payment reminders to customers for unpaid orders.
I came as far as to the point of finding the right trigger. However with the action I am stuck. I can only find the option to send internal mails to staff, not to customers. resending the order confirmation with 1-2 additional sentences would be great.
You can send email automation for abandoned checkout or abandoned carts easily by our Email marketing Avada App quickly.
If you want to send it by Shopify, you can check the guide below :
The Shopify admin keeps the abandoned checkouts for 90 days. Every Monday, if abandoned checkouts last more than three months, your admin will automatically eliminate them.
Step 1: Go to Orders
From your Shopify admin, go to Orders.
Review Automatically send abandoned checkout emails from the Abandoned checkouts area.
Below Send to, select the customers to whom you want to send a checkout recovery email. They could be anyone or email subscribers who give up a checkout.
Sorry for the confusion. But I am not talking about abandoned carts. But about people who bought using payment method âBank-Transferâ and then remain unpaid orders.
Currently, Flow can only send emails to internal/specific email addresses and not to Customers. However, the Flow and Payment Reminders team are working on how to better support payment reminder notifications through Flow, so check back for updates in a little while.
If you want to save time and especially not lose track of your unpaid orders, I would recommend our app Kindly the Payment Reminder. Among other things, it offers you a clear dashboard with all your pending orders, a report about the success of your payment reminders, and a variety of options to schedule payment reminders.
Our customers are very happy with us. But itâs best you try it out yourself - after all, thereâs a free plan and a 15-day free trial for a reason. On top of that, I guarantee you to refund your money if you are not satisfied with Kindlyâs service. Also, feel free to get in touch via our live help chat, we are always standing by to answer your questions in detail.
Automatically email customers on or after the due date for unpaid orders.
What is the due date for a bank transfer?
I donât know how to set it upâŚ
I tried without due date but the email was never sendâŚ

See below. The ability to send payment reminders through Flow was added quite awhile ago. Flow is not implementing a generic system to email customers outside of partners and Shopify Email, or specific actions to send a certain type of email (like Payment Reminders)
I am hoping you will add the ability to specify an accounts payable email field in the customer data so we can send payment reminders directly to accounts payable rather than the buyer. I canât stress how important this is.
Nearly always, invoices need to go to both the buyer and the accounts payable emails.
Hi! Sorry to comment on this after so long, but I am having an issue with the payment reminders not being sent. We make a lot of use of draft orders and weâd like to be able to send our customerâs an automatic email when the due date for payment passes, but all of the internal testing weâve done hasnât resulted in any emails being sent.
Weâd ideally like for the following to happen:
Draft order is created
Customer is emailed the draft order invoice with payment being due within 7 days of the invoice being sent
If 7 days have passed then the customer receives an automatic Payment Reminder email notification
From everything Iâve found this should work by just setting the payment due date on the draft order and sending the invoice, without needing to toggle on the payment reminder. Iâve found where that payment reminder can be edited but no other settings beyond that.
Is there some other setting Iâm missing or something else that needs to be enabled?
If you donât mind to spend some bucks you would get a great experience regarding your topic with our app Kindly.
You could easily set up your reminder plan to schedule reminders for open draft orders after 7 days from the invoice being sent. Thatâs basic procedure.
Whatâs maybe even more interesting to you is our latley published option to send SMS reminders with what we see a much higher conversion rate compared to email.
Finally, also not unimportant, to improve your reminders effectivness you can check your email performance in the analytics page.
Do you mind sharing your flow? I think Iâm trying to achieve the same thing. We place an order and set that payment is due in 30 days for schools that pay with a PO. I can remind them the payment is due on the due date, but I want to remind them 7 and 14 days before.
Yes, you can use Shopify Flow to send payment reminders to customers, but it is designed for a specific billing method. The âSend payment reminderâ action works with orders that have official payment terms (like Net 30 or Due on receipt) set on them.
For regular pending payments, youâll need a dedicated app from the Shopify App Store that specializes in abandoned cart and payment reminder emails.
