How to invoice Tieto

Information for suppliers about invoicing Tieto

E-invoicing

E-invoicing is not just great for the environment – it also cuts costs, streamlines processes and reduces errors. We no longer accept paper or pdf invoices in Finland, Sweden and Norway, and encourage suppliers in other countries to use e-invoicing. For more information, read our Instruction for suppliers.

If you are already set up for e-invoicing, check that your operator or bank can connect with us through the operator network. If they are unable to, contact bix.servicedesk@tieto.com to create a new interchange connection. Our e-invoicing operator for all Tieto companies is Tieto Oyj – the operator's code is 003701011385.

Invoice content requirements

Guidelines on invoice format and content, as well as delivery documentation for physical goods, are explained in Tieto invoice content requirements.

Invoicing addresses

You will find invoicing addresses here, including e-invoicing codes. For addresses in other countries, please get in touch with your local Tieto contact.

Factoring companies

Please note that we do not accept invoices from factoring companies.
