Information for suppliers
We depend on our suppliers to help us deliver first-class solutions to our customers. Developing mutually beneficial and sustainable relationships with our suppliers matters to us. We expect all suppliers to meet the same high standards we set for ourselves - we use our Supplier Code of Conduct as one of the main selection criteria in the sourcing process.
We support sustainability across all our operations. Our Supplier Code of Conduct is based on the United Nations Global Compact, which sets out principles for human rights, labour conditions, environment and anti-corruption. It also includes additional standards on communication and auditing.
You can download our Supplier Code of Conduct here.
We have a strict no purchase order, no pay policy, to enable a more accurate process for invoice payments. Invoices received without a valid purchase order number may be returned to the supplier. If this happens, please get in touch with your order contact at Tieto to request a valid order number.

How to invoice Tieto
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.
Guidelines on invoice format and content, as well as delivery documentation for physical goods, are explained in Tieto invoice content requirements.
You will find new Tieto invoicing addresses here, including e-invoicing codes. For addresses in other countries, please get in touch with your local Tieto contact.
Tieto uses Self-Billing - invoice created by Tieto on behalf of the supplier - as the default invoicing method in EU and Norway (for Norway permit to issue invoice on seller’s behalf must be signed) unless otherwise agreed.
For detailed information see Self-Billing guide for suppliers and other stakeholders.
Please note that we do not accept invoices from factoring companies
