Numos has started online invoicing. Our clients can receive online invoices from us, though we continue to send traditional invoices on paper copies by mail, or as pdf documents by electronic mail. 

We also prefer receiving online invoices from our providers.

The online invoicing address of Numos is  FI9457202320055233, and the gateway is OKOYFIHH.

For our international customers we recommend traditional invoicing in both directions.
