The document discusses moving enterprises to e-invoicing and e-document exchange. It argues that e-invoicing could save 243 billion euros annually in business-to-business transactions in the EU.

Banks are well positioned to provide e-invoicing services to small and medium enterprises through existing e-banking and payment networks. Choosing a common e-invoicing format would also help with widespread adoption.
