He said, new electronic billing program has been running correctly, although initially it was commented that there were problems with the type of maintenance that was being given to electronic invoicing. Now that problems have not already been reported, Mexican companies are ready to begin to generate electronic invoices, he said. However, also considers the need to clarify certain questions concerning electronic invoicing that have arisen from the counters and which arise from very special regimes, for example, of the sector transport about how certain aspects can be handled, or what is the transport document (the letter with which van transport to the interior of the Republic), among many others. According to Mario Zavala, these doubts are normal and will be corrected as time progressed and companies are adapting to this new electronic billing system which undoubtedly greatly enhance your management system. ul.
