Our invoicing information
We prefer invoices to be sent primarily as e-invoices. Processing e-invoices is faster, more reliable, and cheaper for both the sender and the recipient than processing paper invoices.
Billing information for invoices dated December 31, 2025, or earlier:
Lumme Energia Oy
Our operator's intermediary ID is BAWCFI22 (Basware). The full address, including the serial number (business ID), must be included on the invoice. If the address does not include the serial number, the invoice will not be processed and will be returned to the sender by post.
