Dear [Client Name],
I hope you are doing well.
We did not receive payment for the invoice [invoice ID].
Could it be possible that you forgot to pay our bill? If so, would you be so kind as to make the payment so that we can pay our suppliers, too?
For your convenience I remind the invoice details here below:
Invoice ID | Issue Date | Due Date | Amount | Days in overdue
2020-0031 | 15-06-2020 | 15-07-2020 | 968,-€ | +34
You may address the payment on our bank account [bank account number] with your reference [payment reference].
We expect you to pay the bill on August 15, 2020, at the latest.
To guarantee the service you benefit, we have suppliers to pay too. Like us, they love to get paid on time.
I wish you a great day,
