Electronic invoicing is mandatory in many situations in Finland (for example in B2B at the customer’s request). Integrating e-invoicing directly into your own software saves time and reduces errors.
Operators
In Finland, e-invoices are transmitted via operators (e.g. Maventa, Apix, OpusCapita, Posti Messaging). The operator forwards invoices to the recipient’s operator in Finvoice or the European EN 16931 format.
Sending invoices
Your software creates the invoice as XML and sends it to the operator via API (REST or SFTP). The operator handles routing to the recipient.
Receiving invoices
The operator forwards incoming invoices to your system. You can process them automatically: approvals, postings, payments.
