Changing the type of invoice from paper invoice to electronic invoice

If you want to start using electronic invoices instead of paper invoices, please contact HSL Corporate Sales by email at yritysmyynti@hsl.fi. Please indicate in the email message which company or account in the HSL Business Portal the change concerns. In addition, provide your company’s e-invoicing operator and web invoice address.
Please note that an electronic invoice is not an email invoice. It is not currently possible to opt for email invoices.
