How to automate unpaid invoice reminders?

Shopify Discussion

Topic summary

Goal: Automate emailing customers about unpaid invoices, ideally sending reminders every X days until paid.

Built‑in capability:

  • Shopify sends one invoice reminder by default. Path: Settings → Notifications → Invoice Reminder.

Native automation (plan-dependent):

  • If on Shopify, Advanced, or Plus, use Shopify Flow to schedule repeated reminders at set intervals (e.g., every X days) after triggers like invoice sent or payment due.

App options suggested:

  • Order Automator: general automation app that can handle scheduled follow-ups.
  • Kindly – Payment Reminder: purpose-built for unpaid invoices. Features include configurable number of reminders, custom schedules (triggers: order receipt, payment due, invoice sent), excluding specific orders from follow-up, auto-cancel after unsuccessful attempts, dashboard of pending orders, and custom email branding; runs automatically once set up.
  • ReConvert was also mentioned, though it’s typically focused on post‑purchase flows.

Other notes:

  • One participant offered help setting up workflows but did not provide links.

Status: No final resolution from the original poster. Clear paths are: enable the default reminder, use Shopify Flow (if available) for repeated reminders, or install a dedicated app.

Hello! How do I send an automatic email to a customer about an unpaid invoice? Ideally, I’d love to send a payment reminder to them every X days until it is paid. Right now we are doing it all manually and its very time consuming. Thanks!

Hi @LCo ,

We have been at the same point with our shop a few years ago. Back then we decided to develop an app specifically for this purpose. And as we were at it we wanted to do it right. And so Kindly came out to be a really helpful app that covers the most important features:

  • Amount of reminders

  • Custom schedule (Trigger: Order receipt, payment due or invoice sent)

  • Choose to exclude orders for follow-up

  • Cancel orders after unsuccessful follow-ups

  • Dashboard with all pending orders

  • Custom email branding

  • and more…

Once it’s set up, it just works in the background and saves you the whole back-and-forth of manual chasing.

Hi,

Hope this will help

  • Shopify already sends one reminder by default : check Settings → Notifications → Invoice Reminder

  • If you’re on Shopify/Advanced/Plus use Shopify Flow to send repeated reminders every X days. If Flow isn’t available apps can automate multiple follow-ups on a schedule.
