Our customer service is open online and by telephone, the customer service desk at Helsinki, Kamppi is closed until further notice.
We issue invoices through most e-invoice operators. We require the following information for e-invoicing.
If your company does not want to have all its bills as e-invoices, please specify the electricity contracts/contract numbers which will not be included in e-invoicing.
Remember also to inform changes in e-invoicing. Incomplete or incorrect e-invoicing information we can not handle.
