The Enterprise Bottleneck

A high-growth multi-brand fashion retailer struggled with decoupled online and brick-and-mortar inventories, resulting in frequent out-of-stock cancellations during flash sale surges and disconnected loyalty data.

Engineered Architecture & Approach

Innvira Soft engineered a headless e-commerce architecture powered by Next.js App Router and a microservices inventory engine. The system syncs inventory across 140 retail outlets and the central e-commerce warehouse in sub-second intervals with predictive back-order allocation.

Engineered Sub-Modules
  • Sub-second multi-location inventory reconciliation
  • Headless Next.js storefront with 98+ mobile Lighthouse score
  • Unified omnichannel loyalty reward wallet
  • Point-of-Sale (POS) barcode scanner integration

Working with Innvira Soft was the smoothest engineering collaboration we have experienced. They delivered on schedule, under budget, and built a platform that effortlessly handled our biggest holiday season ever.
