How do I remind customers about unpaid invoices automatically?

In Settings › Automatic messages, turn on Unpaid invoice reminder and pick the days. Late invoices get up to 3 reminders, spaced by those days.

Updated October 22, 2026

Turn on Unpaid invoice reminder in Settings › Automatic messages. When an invoice is late by the number of days you pick, Alori reminds your customer, then again every that many days, 3 times at most. It stops as soon as the invoice is paid.

Also called: payment reminder, dunning, overdue notice, collections, rappel de paiement, relance de facture, facture en retard

Step 1: Open Automatic messages

Click Settings, then Automatic messages. Only the owner sees this tab.

Click: Settings › Automatic messages

Step 2: Turn on Unpaid invoice reminder

Turn on Unpaid invoice reminder. It saves right away and you see Saved.

Click: Unpaid invoice reminder

Step 3: Pick the days

Under it, set Days. It starts at 7. With 7, the first reminder goes when the invoice is 7 days past its due date, the next 7 days later, and a last one 7 days after that. Type a number from 1 to 60, then click outside the box to save.

Step 4: Choose email, text or both

Under Send by, pick Email, Text or Both. It starts as Email. With Text or Both, you can change the wording. Click Add a field to put in the customer's name, the invoice number or the amount, check the preview, then click Save the text.

Click: Send by › Save the text

Good to know

  • An invoice is late once its due date passes. Its due date comes from Payment terms (days), lower on the same page. A late invoice turns Overdue on its own.

  • Paid invoices never get a reminder. Click Mark paid when you get paid another way.

  • Turning it on never sends a pile of reminders for old invoices. Only invoices whose first reminder day comes after you turned it on count.

  • Reminders go out only from your published app, between 8 a.m. and 6 p.m. in the Time zone set on this page. Alori checks every hour.

  • Each email costs 0.01 credit. Texts cost credits too.

  • Invoice ready is a different message: it goes a minute after an invoice is made.

  • You can also ask Ask Alori: "Remind late invoices every 10 days."

If it doesn't work

  • "Texts go out once your number is active, in Alori under Phone system." Your app has no active phone number yet. Pick Email for now.

  • "That didn't work. Try again." Your change didn't save. Try again in a moment.

  • A late invoice got no reminder. Check that the customer has an email (or a phone for texts), that your app is published, and that it hasn't had 3 reminders already.
