Case Study: IAG Loyalty Retail achieves scalable, automated order fulfilment with Leighton’s serverless OMS

IAG Loyalty Retail delivers a serverless OMS in 4 months with Leighton

IAG Loyalty Retail (iaglr) needed an order management system capable of handling over 2,000 daily orders for its Avios Shop, an online portal for redeeming loyalty points. Their legacy batch-processing system caused delays and manual work, which was insufficient for their multi-brand expansion plans and integration with multiple third-party logistics providers (3PLs). They engaged the vendor, Leighton, to build a modern solution.

Leighton designed and delivered a scalable, serverless order management system (OMS) on AWS in just four months. The event-driven architecture automated order fulfilment, provided real-time tracking, and seamlessly split orders by brand for different 3PLs. This solution gave iaglr full visibility and control, eliminated manual processes, and established a resilient platform for future growth.
