Tieto and Siirto partner to improve e-invoicing experience in Finland

Tieto and Siirto, an instant payment method with more than 1 million registered users in Finland, are partnering to make digital invoicing more accessible, efficient and user-friendly for both businesses and consumers in Finland.

The collaboration will enable businesses to retrieve their customers' e-invoice addresses and send the first invoice directly to a customer’s online banking service. This is made possible by Siirto's newly launched centralized registry, combined with Tieto’s Multichannel B2C e-invoicing solution. For consumers, this means a smoother digital payment experience.

"Consumers shouldn't need a separate app to pay or receive an invoice – their bank app should already do it. No extra downloads, no friction. That's the direction instant payments in Finland is heading, and Tieto is a key partner in getting us there," says Mikko Ketola, CEO of Siirto.

“Our partnership reflects a shared commitment to creating smoother digital payment experiences, reducing reliance on paper-based invoicing, and advancing the future of financial services in the Finnish market,” says Teemu Petäjäniemi, Product Area Manager, Multichannel in Tieto.

"We are excited to collaborate with Siirto as they bring a new and innovative approach to the Finnish invoicing ecosystem. Together, we can help organizations deliver invoices through the channels consumers prefer and contribute to the continued digitalization of payments and invoicing in Finland,” says Gard Heiaas, Head of Multichannel and Business Information Exchange in Tieto.
