Case Study: DIA achieves rapid omnichannel integration (352 stores in 14 weeks) and 100% YoY conversion growth with VTEX

A race against time accelerating grocery ecommerce during the pandemic

DIA, a leading grocery chain with 6,626 stores across Argentina, Brazil, Portugal and Spain and more than 20 million customers, needed to rapidly scale its ecommerce and omnichannel capabilities when the pandemic hit. The main challenge was to show customers real-time assortment and stock from individual stores and fold 352 supermarkets into its online operations quickly — a task DIA addressed using the VTEX Commerce Platform.

VTEX implemented an omnichannel architecture that migrated DIA to VTEX in roughly three months and integrated 352 stores in 14 weeks, unifying food and non-food ecommerce and enabling store pickup. The solution cut logistics costs, reduced inventory rupture and boosted revenue: DIA saw a 100% year‑over‑year increase in conversion rate and roughly 50% of customers opting for in‑store pickup, underscoring the measurable impact VTEX delivered.
