Fact Sheet: Simplified Interline Settlement (SIS)

  • SIS is the electronic invoicing platform developed by IATA in order to remove all paper from the invoicing and settlement of industry services. The service was inaugurated in October 2011.
  • As part of the design, the industry has agreed to a single standard for the data content of electronic invoices (IS-XML), allowing recipients to process and validate incoming invoices automatically. The use of a single standard simplifies business activity for the industry, and allows suppliers to use one invoicing standard for all of their airline customers.
  • SIS identifies invoices that are for settlement by the IATA Clearing House (ICH) and enters the claim automatically
  • In 2013, $66 billion in invoices were processed through the service for settlement by the ICH and other industry settlement services doubling 2012 values.
  • In 2014, SIS is showing continuous growth both in terms of invoices and the amount of money being handled. At the end of October 2014, SIS processed USD$59.97b, nearly 8% more than the same period in 2013. The number of invoices processed through SIS in the same period was USD$1.23 million, over 2% higher than the same period last year.
  • The service is being used in over 180 countries.
  • With the active support of the airlines and the supplier community, service participation is progressively expanding throughout the air transport industry. 
  • At the end of October 2014, there were 585 SIS participants: 368 airlines and 217 suppliers. Additional 592 members have been enabled in SIS as receivers of electronic invoices, in order to capitalize on the system functionalities and maximize efficiency on the invoice sender side. A total of 1,177 members currently participate to SIS. 
  • Any airline or entity that engages in business with airlines can benefit from joining SIS. Using the service allows members to bill and settle with over 1,100 companies in the air transport industry.
