About Wärtsilä in Finland

Wärtsilä prefers e-invoices

e-invoicing is a solution for invoicing electronically, and it suits both large and small companies. An e-invoice is a modern, reliable, secure, cost-efficient and practically paperless method of handling and processing invoices for goods, services and other expenses.

In B2B (business-to-business) e-invoicing, the invoice information is conveyed from the invoice issuer's invoicing system directly to the recipient's financial administration IT system. This ensures fast and cost-efficient handling of purchase invoices. Wärtsilä prefers to receive purchase invoices as e-invoices and encourages all suppliers to send their invoices to Wärtsilä in an electronic format.
