A101 is Türkiye’s largest discount grocer with 11,000+ stores. Its digital commerce was migrated off a black-box legacy vendor onto Retter. Today the platform runs 5 million+ e-commerce transactions a year on AWS serverless, with shared services, integrations and operational logic behind all three storefronts.
