By using Design Science Research (Hevner et al., 2004) , we developed an IT artefact on Microsoft Azure Workbench with an Ethereum Parity implementation that proved it possible to let a Smart Contract hold VAT of invoices.

How can a DLT-enabled IT artifact be designed for financial reporting automation and VAT settlement with a specific focus on an open-book invoicing platform offered by the Danish Business Authority to trading partners in the SME segment?
