Joining Simplified Invoicing and Settlement (SIS) instantly connects you with more than 420 airlines and intermodal entities exchanging interline billing data electronically. SIS eliminates the paper from the interline billing and settlement processes increasing efficiency and reducing costs; it enables processing automation which helps reduce billing duplication and simplifies reconciliation.
Who can join SIS for interlining?
All airlines (IATA and Non IATA Members) and their intermodal partners are eligible to become SIS participants under the "SIS for Airlines & Intermodal" program. This membership covers all 4 submission classes: Passenger, Cargo, UATP and Miscellaneous/Non-Transportation. The participation fees incurred under this model are variable, based on budgetary expectations of operating cost, and vary according to the size and status of the participant (larger, smaller, etc.; IATA, non-IATA, etc.). This is the core agreement for SIS Participation and includes governance rights such as the ability to vote for changes to the standard industry agreement terms, or to vote for changes to functionality at the SIS General Meeting.

ARC (Airlines Reporting Corp.) – ARC operates COMPASS® which houses transaction and prorate data for the purposes of settlement.
A4A (Airlines for America) – The trade group for U.S.-based airlines.
ATPCO – ATPCO, amongst other services, operates the Sales Exchange process whereby sales for First & Final™ transactions are extracted, prorated, and sent to the uplifting carrier.
Auto-Billing – A feature of SIS whereby a billing carrier is able to submit a list of uplifts. SIS will then find the prorate (either a stored own prorate or an NFP) and create the necessary billing, settlement, and invoice files. A pro-forma invoice is sent to the billing carrier daily, and invoices are sent to the billing and billed carrier on settlement.
BSP (Billing and Settlement Plan) – An IATA service for the settlement of ticket revenues between agents and carriers. BSP fees can appear on electronic invoices. More information on BSP
BIETA;Bilateral Interline E-ticketing Agreements - The IATA Bilateral Interline E-Ticketing Agreements (MITA) publication that provides all the passenger and cargo bilateral E-ticketing interline agreements. BIETA outlines the bilateral agreements whereby passengers and cargo use a standard traffic document (i.e. passenger ticket or air waybill) to travel on various modes of transport involved in a routing in order to reach a final destination.
Billing Memo -An authorized debit transaction from one invoicing member to another using appropriate source and billing codes.
Block Chain - Is a decentralized and digitized public ledger of all crypto-currency transactions. Completed transactions are recorded as an “added block” to the chain in chronological order, it allows participants to keep track of digital currency transactions without central recordkeeping

MITA - Multilateral Interline Traffic Agreement - Multilateral Interline Traffic Agreement - The IATA Multilateral Interline Traffic Agreements (MITA) is publication that provides the passenger and cargo Interline Agreements that spell out which airlines have agreements and the basic rules airlines follow when processing revenue and issuing documents for carriage on each other’s services. It outlines the multilateral agreements whereby passengers and cargo use a standard traffic document (i.e. passenger ticket or air waybill) to travel on various modes of transport involved in a routing in order to reach a final destination.
MPA - Multilateral Prorate Agreement - Participating MITA concurrence members are subject to the Multilateral Prorate Agreement (MPA) rules which calculates the revenue share per flight coupon on a ticket and as a result the value an airline will receive for carrying an interlining passenger on any given journey segment.
NDC - New Distribution Capability - This is a travel industry-supported program (NDC Program) launched by IATA for the development and market adoption of a new, XML-based data transmission standard (NDC Standard). The NDC Standard enhances the capability of communications between airlines and travel agents.
NFP (Neutral Fare Prorate) – A prorate created by a “neutral” party, as currently used within First & Final™ settlement. Because of their neutral nature, NFPs are less likely to get rejected by the billed carrier, even outside of First & Final™. In the future, NFP values will be available to all carriers that wish to use them.
- Final – Final NFP values will be similar to First & Final™ and supported by an agreement between the carriers stating that Final NFP values cannot be rejected.
- Non-Final – Non-final NFP values are not supported by a bilateral agreement and can be rejected in case of dispute. Non-final NFP values offer the benefit of a lower likelihood of rejection.

Stored Own Prorate – A sales carrier will have the ability to upload prorated fares to Integrated Settlement and specify who may download those fares. Integrated Settlement will then store the prorates, at which point they are considered “stored own prorate”.
Optionally, the sales carrier may specify that the prorates are not to be stored but only switched, in which case they’re sent directly to the planned uplifting carrier.
SDF - Supporting Documents File - zipped file containing all supporting documents associated to submitted billing transactions in SIS.
SOC2 - Certification of Controls at a Service Organization Relevant to Security, Availability, Processing Integrity, Confidentiality or Privacy.
SPA - Special Prorate Agreement - bilateral prorate agreement between interline partners that supercedes the Multilateral Prorate Agreement.

Who is eligible to join?
Any airline is eligible to join SIS, whether or not they are a clearing house member.
Non-airlines may also join SIS provided that they do business with airlines. It is now possible for non-airlines to do business with other non-airlines through SIS.
How do I join SIS?
Access to SIS is granted once the Integrated Settlement Participation Agreement has been signed and the participant has passed the necessary certification process. This process is detailed in the Sign-Up Guide. These documents will be made available in the Join SIS tab above.
How do I know when my e-Invoicing partners are migrating to SIS?
Airlines’ migration plans will be shared on a permission-basis. In the SIS Forums, there is a designated place where planned migration dates of airlines are stored. This information is released to the parties that are willing to share their own migration plans with us and their fellow carriers that have access to the list. For more information regarding this, please contact us via the IATA Customer Portal or download the SIS Member List (xls) for the updated list of active SIS members.
What are the charges of using SIS?
SIS is run on a cost-recovery basis. These charges will be specified in your Integrated Settlement Participation Agreement.
A complete sample of the "Standard Agreement for SIS e-Invoicing Services – Non Transportation" (pdf) is available for information purposes only, not for signature. The costs of using SIS under this program are outlined in Attachment D (pdf) of the agreement.
Signing Up & Migration Steps
What are the key submission options for SIS?
One of the many benefits of SIS is that interline partners will no longer depend on each other when it comes to choosing the formats to submit files. Under SIS, participants may select among various formats to submit files and this will not affect the way their billed entities receive the files.
The three submission options are IS-IDEC, IS-XML, and IS WEB (manual input via web interface).
A matrix outlining the possible options to submit files/invoices can be found in the Integrated Settlement Participation Guide (ISPG) Chapter 2.3.
What is the Sandbox?
The Sandbox is a dedicated separate environment primarily having the SIS validation components. The purpose of the Sandbox is to ensure that the outputs generated by your individual revenue accounting systems are as per the requirements of SIS.
In the Sandbox, you will be able to upload SIS format files (IS-IDEC and IS-XML) without any restriction on the number of files. SIS will validate your input file (IS-Validation) and will also check if the minimum certification requirements are met. Further details on the Sandbox are specified in the Sign-Up and Certification Guide.
How can I learn about using SIS?
Can formats of invoices be mixed? e.g. IS-XML for one Charge Code and IS-Web for another Charge Code?
Yes. SIS offers the flexibility for all invoices submitted in any format to be viewed in IS-Web. Please also refer to the ISPG Chapter 2.3 for more information on the overall flexibility of file transmission choices.
How will the Call Day Adjustments (CDA) operate with SIS?
The ICH will generate CDA invoices as now and will create an IS-XML file (Charge Category: Service Provider / Charge Code: CDA) on the initialization of Clearance Period 2. Additional to today, the IS-XML file will also provide details of original invoices included in the CDA to simplify reconciliation of CDA amounts and enable allocation of any adjustment to the original invoices. As the invoice number format used by the ICH today exceeds the number of characters available in SIS, the number format will be changed to: "CD" + YY (invoice year) + MM (invoice month) + XXXX (incremental number), e.g. CD10080023 would identify the 23rd CDA invoice generated for August 2010.
What are the costs associated with using iiNet?
For the basic file transfer functionalities to/from SIS, no transaction fees will be applied. The access to iiNet using a manual account will also be free of charge. Participants wishing to set up a new automated file transfer account would be charged the current iiNet fees. Any optional iiNet functionalities beyond the basic file transfer, will be subject to iiNet current fees. For further information, please contact iiNET via the IATA Customer Portal.

Passenger Rejection Reduction Initiative
The Interline Billing and Settlement (IBS OPS) Working Group has been tasked to improve efficiency by cutting down on incorrect rejections via education, awareness, proposing changes to the billing rules, and adding new validations in SIS.
The Passenger Rejection Memo Reduction initiative is endorsed by the IATA Financial Committee to support accurate interline billings that ultimately reduce the number of passenger rejection memos in the industry. The IATA IBSOPS WG and Rejection Reduction Team have undertaken several actions to reduce the number of passenger rejections, such as:
- Introduce New Validations in SIS
- Changes in the RAM rules that impact rejections
- Multiple presentations/workshops at industry meetings
- Continuous reporting and communications to the industry
- Publication of Best Practices Document
- IBS OPS recommendations to industry on handling of rejections
Due to the COVID-19 Global Pandemic, this initiative is now considered paused. The new IATA Working Group (previously IBS OPS WG) and the SIS Operations Team will monitor internally ongoing trends, continue to publish quarterly dashboards and propose industry best practices. Once the related passenger interline invoicing volumes begin to stabilize, a new target will be proposed by the new IATA Working Group (previously IBSOPS WG).
The charts below illustrate the count and USD amount of rejections over the past years.
