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 all parts of 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
  • At the end of April 2014, some 495 airlines and other industry service providers were signed up to SIS
  • 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 money. At the end of April 2014, SIS processed $20.54 billion, 7.68% more than the same period from 2013. The number of invoices processed through SIS at the end of April 2014 was 443,620, 4.63% higher than the same period last year. The service is being used by airlines and other service providers in 163 countries, making it possibly the most widely used e-invoicing service in the world

With the active support of the airlines and supplier community, service participation is progressively expanding throughout the air transport industry
