Create payment reminders
On your SumUp profile, click "Invoices" in the left navigation panel.
Select "Invoices" and then choose the unpaid invoice to send a reminder for.
Click the three dots in the top right of the screen and select "Create", then "Reminder".
Optionally, add fee for the reminder.
Click "Create" in the top right corner.
Here you'll see a draft of your updated invoice with the option to download or print it.
Once downloaded or saved, the reminder can be sent or mailed to your customer.
Remind customers of unpaid invoices by enabling automatic payment reminders to be sent once the invoice's due date passes.
