Tieto has implemented a No PO No Pay policy which means:
Purchases are to be done via a Tieto valid Purchase Order (PO). A PO is created and submitted by Tieto Procurement department. It is mandatory for suppliers to quote a valid Purchase order number on all invoices to Tieto.
The No PO No Pay policy offers significant benefits to suppliers as well as to Tieto.
