How to get started with e-invoicing?

Fortum companies want to ensure the e-invoice quality. The following instructions are for sending e-invoices with a service providing partner (operator)

STEP 1. Contact your e-invoicing service provider

If you are already cooperating with an e-invoicing service provider, please contact the service provider and ask them to ensure that they are connected to Basware.

STEP 2. Create a test invoice

Generate a test invoice according to the content requirements explained in e-invoicing requirements In order to automate invoice handling, it is important that you include on your test invoice all the fields that have been marked as mandatory. It is highly recommended that you mention in both header and line level data that the invoice is just for testing purposes, by typing “TEST” somewhere to the invoice free text fields. Add also text “TEST” to invoice image if possible.

STEP 3. Submit the test invoice

Send the test invoice to your e-invoicing service provider, and request them to forward it to Basware. Basware’s Business Transactions service verifies and converts the invoice according to the Fortum’s requirements, and forwards it to Fortum. Right after you have sent the test invoice, please send email with below information to e-invoices [at] fortum [dot] com

The message should include the following information: 

  • Delivery date and time of the invoice
  • Total amount of the invoice
  • Invoice number
  • Order number
  • Contract number
  • Reference person (email address if possible)
  • Name of the sender
  • Name of the recipient
  • e-Invoice address of the recipient
STEP 4. Receive the feedback

After reviewing the information about your first test e-invoice, we are ensuring that all required data required has been received for the automatic handling of the invoice. You will receive a confirmation by e-mail in 2-4 days

STEP 5. Start sending e-invoices

Once the test invoices have been approved by us, you can start sending production invoices.
