Invoicing Instructions
Our invoicing instructions have changed on 1st of January 2026.
Remember to include all the necessary references on your invoice
All invoices must include a reference code, received from our contact person, so that the invoices can be automatically balanced. This can be:
- The purchase code in the purchase order, e.g. INFR-xxxxxxxx, KAVA-xxxxxxxx, KLOY-xxxxxxxx or HKL-xxxxxxxx
- An invoicing agreement reference
- The email address of the conformity inspector (firstname.lastname@kaupunkiliikenne.fi)
- The cost centre of the conformity inspector, if provided in connection with the purchase order
- Your contact information (email address and phone number) to help us contact you.
If an invoice does not include all the information we have requested, it will be returned back to the sender.
Calculating the Payment Period
According to the order’s terms and conditions, the last payment date is calculated once we have received the invoice.
When sending an e-invoice, the payment period begins on the same day.
