First, you need to create a Finvoice e-invoicing agreement with your bank or another operator. After that, you can send us an e-invoice request by email at finvoice-laskutus@vaasansahko.fi.

For e-invoicing, we need the following information:

  • Organization name
  • Business ID
  • Customer number
  • Contact details of the e-invoicing representative
  • OVT identifier issued by the operator
  • E-invoice address
  • Information on when e-invoicing can begin
