We accept, process and archive purchase invoices as e-invoices only. Please send invoices as e-invoices through the e-invoice operator, OpusCapita Solutions Oy. Details on the ordering unit, project or person must be clearly marked on invoices.

All paper invoices will be returned unpaid. In addition, we will not accept invoices sent via email, as they are not e-invoices.

If you do not have a system for creating e-invoices, you can create and send e-invoices through the e-invoicing service that the Finnish government provides (Supplier Portal). The service is currently provided free of charge. Log into the e-invoicing service and review the related instructions on the government e-invoicing website maintained by the State Treasury. Contact Basware Supplier Portal user support if you have any questions related to the service, tel. +358 600 97 373 (calls cost EUR 2.51/min + local network charge), service hours: Mon–Fri 08.00–17.00
