Information for suppliers

Find out more about how we work with our suppliers.

Becoming a supplier

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.

Sustainable supply chain

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, and read more about our sustainability work.

No PO, no pay

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.
