Billing and Settlement Platform (BSP)


Whenever you make a BSP transaction or access the BSPlink, you’re probably using our technology as we power two-thirds of the world’s BSP processes.

Our partnership with IATA started with the Billing and Settlement Plan (BSP), simplifying and automating the exchange of data and funds between travel agents and airlines.

We also power BSPlink, IATA’s comprehensive distribution platform for the BSP community. This has pioneered the automated transfer of data in a secure environment, delivering airlines’ account receivables in a single financial transfer.

Neutral Fare Proration (NFP)


We provide the industry’s most accurate NFP (Neutral Fare Proration) engine. It’s the backbone of the First & Final Billing service, which we jointly offer with ATPCO.

Read More

Through NFP, we help airlines reduce the cost of interline operations, deliver billing information within 24 hours of receipt of sales data (sales-based proration), and support billing information based on lifted coupons. By reducing the manual processes associated with interline billing, airlines can eliminate the costly maintenance of an in-house proration engine.

Our proven proration capabilities power our Order Accounting solution, ready to meet your current revenue accounting demands while supporting your move to a retail-centric world.

Simplified Invoicing and Settlement (SIS)


We’ve been IATA's primary SIS technology partner, managing the platform since 2009.

SIS standardizes, facilitates, and expedites interline billing and settlement, using just one e-invoicing standard. It covers more than a million invoices annually with a value of over $70 billion. Through SIS, we simplify financial processes including reconciliation, and connect airline business partners on a single platform. This saves airlines and agents as much as 2% on operating expenses, adding up to hundreds of millions of dollars each year.
