eFaktura is a Norwegian electronic billing system issued by Nets Branch Norway AS (Nets).
The system involves both business-to-customer (B2C) systems, branded as eFaktura, and business-to-business (B2B) branded as eFaktura B2B.
Any company or organisation can sign an eFaktura agreement with their bank (though usually for a typically five-digit NOK startup fee) and send electronic bills to any client as long as they have a Norwegian online banking account.
The ordinary eFaktura includes a specification of the bill, and the entire bill or invoice can be seen in the online banking system, and printed if so desired.
Nets offers services to send out paper bills to any company not able to receive electronic billing.
