Knowledge about e-governmental service delivery towards businesses in general and the use and choice of service channels in particular is lacking. Current insights are mostly based on research in the context of citizens. Important differences in both domains can be found in the more networked character of the business context. These differences show that research towards the business context is needed. In order to fill the gap we provide an overview of existing knowledge about channel choice in G2B context. To conclude, we present a research agenda for future research on this topic.
