Switching from paper invoices to e‑invoicing

If you want to switch from paper invoices to e‑invoicing, please contact HSL Corporate Sales at yritysmyynti@hsl.fi. In your message, please specify which company or customer account in the HSL Business Portal the change applies to, as well as your company’s e‑invoicing operator and e‑invoice address.

Please note that an e‑invoice does not mean an invoice sent by email. Email invoices are not currently available.
