E-invoicing stands for electronic invoicing. E-invoices are generated and processed fully automatically, without the intervention of human actions. UBL is annexed to a digital PDF invoice, a sort of Excel attachment. All data appearing on the invoice is then stored in a readable, structured form for software. This XML file is then called UBL for invoices. More and more software packages offer the possibility to send UBL invoices.
Benefits of UBL billing? It helps to carry out the administration cheaper and more efficient with a smaller chance of errors.
