Iceland Supercharges Availability Data with Composable Architecture

Iceland is a British supermarket chain headquartered in Deeside, Wales, known for its focus on frozen foods, alongside a full range of fresh and dry groceries. A household name in the UK, its long-running slogan — "That's why mums go to Iceland" — has cemented the brand’s place in popular culture.

Iceland’s ambition was to manage price books for each of its 720 stores with price and availability data extending 14 days ahead. In their SiteGenesis implementation, SFCC’s limitations meant they could only display three days of availability — a major barrier to providing accurate, customer-specific pricing and stock visibility.

64Labs built a proof of concept using Algolia, a leader in headless search, to demonstrate how a composable architecture could bypass SFCC’s price-book limitations. The POC impressed Iceland with its speed, flexibility, and scalability.

They commissioned a full Progressive Web App (PWA) to:

• Remove the 3-day availability constraint
• Deliver store-specific pricing and availability for all 720 locations
• Improve site performance and user experience ahead of a planned year-long SFCC upgrade

The project took six months from start to launch and went live in 2024.

Results

• 14-day store-specific price and availability now possible across all locations
• Performance and UX improvements consistent with other composable rollouts
• Future-proof architecture ready to integrate with upgraded SFCC instance in 2025

Iceland’s success shows how composable architecture can overcome core platform constraints - unlocking capabilities that traditional monolithic setups can’t deliver. For retailers with complex pricing and inventory rules, composable approaches offer flexibility, speed, and scalability without waiting for a full platform upgrade.
