You can now configure automated reminders to be sent your customers for payment requests that have not been actioned.
This setting is disabled by default, so you'll need to login and enable it on your account per your preference.
Reminders are:
Sent on payment requests that have a customer email or mobile available
Sent via SMS and email (as available)
Sent only once, 3 days after the payment request is created
A copy of the original payment request, with an additional line "Automated reminder"
You can configure reminders:
As a default setting per finance option and separately for card/EFT payments
This will also apply to payment requests created via API
Navigate to "Settings | Finance options" and toggle on/off the reminders per finance product
As an override per template
Navigate to "Settings | Templates" and edit a template to toggle on/off reminders for requests created using this template (setting is in the top card)
