Query: Enhancement of the e-Invoicing Systems by Increasing the Efficiency of
  Workflows via Disruptive Technologies   E-invoicing is a rapidly growing e-service in Europe as well as in the world.
It is identified as a substantially significant element in progressing towards
the goals of Digital Economy in the European Union.
  This thesis focuses on identifying inefficiencies in e-invoicing systems
currently in use and the opportunities to apply emerging technologies such as
artificial intelligence and robotic process automation, in order to increase
efficiency and level of automatization. The study incorporates expert opinions
and users perceptions in e-invoicing systems on the status quo and the
necessities for higher automation. We focus on e-invoicing systems in the
Baltic region consisting of the countries Estonia, Latvia and Lithuania. Based
on the conducted research, the drawbacks in e-invoicing systems were identified
related to operational, technological and information security related.
Furthermore, the automation opportunities and general requirements for
automation were identified. The functionalities that can be improved are
discovered as well discussed in this thesis and the advantages of using
emerging technologies in the context are explained. Based on research outcomes
we propose a conceptual e-invoicing ecosystem and present recommenda-tions for
its application along the future work needed in that field.
