Mexico imposes electronic invoices
The Mexican VAT authorities are to require large companies to produce approved electronic invoices from the start of 2014.
Any business with a turnover in excess of MXN 250k will be obliged to issues einvoices. Companies below this level can do so too on a voluntary basis.
The mirrors the EU 2nd VAT Directive of Invoices, which required all member states to use e-invoices from the start of 2013.
