We are currently re-designing our B2B / B2G Daoinvoice concept. We will publish a new concept paper later this year (2020). The documentation of the old design can be found on the botom of this page.




We participated the 2015 Nordea bank startup accelerator programme and built the first versions of the Ethereum blockchain invoice factoring service with the help of Nordea’s Digital banking team. Here is a short demo video.

We spent some 2016/2017 months and worked together with a consortia of major Scandinavian banks, insurance companies, B2B integrators and government agencies to build Ethereum blockchain tech based L2 infrastructure layer for B2B digital invoicing.  We built the demo and got some feedback (“too early” being the typical comment).

The 2017 version more or less implemented the current B2B e-invoicing concept on top of consortia blockchain. We share some slides below but contact us for more information if you are interested.

We closed the first digital invoice on blockchain deals 10/2016.  Together with a consortia of major Scandinavian banks, Insurance companies, B2B integrators and some relevant government registries and agencies we are building the first cornerstones for blockchain and smart contract technology based B2B e-invoicing

The customer portfolio in this project included: Government Business registries / Tax authorities / Banks / Insurance companies / Large invoice senders / Invoice receivers / B2B business integrator – operators / payment processors / Banking IT / SME book keeping alliance /

Here is the documentation of the project. Links to the demo and the code can be found in the documentation.
