According to EU Directive 2014/55/EU, all public contracting authorities and entities must be able to receive and process electronic invoices. But in transposing this directive into national law, many EU states have gone one step further, introducing mandatory e-invoicing for suppliers and contractors. This means that all invoices sent to public contracting authorities must be electronic, and that invoices in paper form will no longer be accepted. Italy has gone so far as to impose mandatory e-invoicing for all domestic invoices, including those sent to companies and private citizens.
