Why and how
Mustang: because invoices simply need to get faster.
Mustang makes your software read, write and validate (e.g. re-calculate) machine readable invoices, orders, or delivery advices:
Machine-readable data speeds up invoice processing, makes it less error prone, is often requested by your customers and has become mandatory e.g. for german B2G invoices and
Italian (and soon French!) domestic B2B invoices (read more about electronic invoices).
Machine readability is achieved with formats such as Cross Industry Invoice (XML), XRechnung (per se not a format, details), or Factur-X/ZUGFeRD/Order-X (Cross Industry Invoice XML embedded into human readable PDF). Unlike for more complex exchange, called EDI (e.g. Peppol), those formats do not need to support additional protocols, gather extra address information or run custom servers.
