Payments and delayed payment

​​​​​​​​​​​​​​​​​The invoice must be paid on the due date, at the latest. Remember to always report the invoice’s reference number.

If you need a longer payment term for your invoice, contact our customer service by email before the due date, asiakaspalvelu(at)hsy.fi. Please include your invoice’s reference number in your message.

Despite the new agreed upon payment term, penal interest will be applied, starting from the original due date of the invoice. 

​We will not move the due date permanently, due to a payday, for example.​
