Among the many actors of the APiR system, the Order Sorting Node ( NSO ) and the Exchange System ( SDI ) immediately stand out , which private operators have also learned to know well in recent years , with the entry into force of the obligation of electronic invoicing .

and not only because an order has always been followed , as a rule , by a austria phone data payment : the law in force , in fact, provides that, starting from next January 1, 2021, at least as regards the purchase of goods, all electronic invoices to PAs contain the details of the electronic order in question . Otherwise, Public Administrations will not be able to settle the invoices received, as they do not comply with the law.

This is a constraint that PA suppliers will have to keep in mind, but which will also allow them to obtain significant advantages. Reconnecting an invoice to the corresponding order detail is, in fact, an immediate process, no intermediate steps are necessary and the possibility of errors is reduced to a minimum , thanks to the use of unique identifying elements. In fact, the reconnection step between invoice and order must occur through the so-called " identification triplet" , a combination of information to be included in the invoice: unique order identifier, issue date, unique identifier of the subject issuing the order.
