From my 10+ years in the software development industry, one major consideration is how well the agency understands not just mobile tech, but the eCommerce domain itself because building a fast-loading app is one thing, but syncing it with live inventory, handling order logic, multi-currency setups or integrating with CRMs like HubSpot or Zoho is a different game.

At Impero IT Services, we recently helped a UAE-based luxury fashion retailer transition from a sluggish WooCommerce site to a robust Flutter-based mobile app connected via custom APIs. The client needed real-time stock updates across physical stores, flash sale handling, and a smooth loyalty rewards engine built from scratch. We used Firebase for push notifications and offline cart support and implemented Stripe and Razorpay for multi-gateway integration depending on user location.

What made the biggest difference?

Custom API architecture with caching to reduce server load.

Focus on UI/UX tailored for mobile shopping behavior—swipe-based browsing, wishlist toggles, and one-click reordering.

A modular codebase that allowed future integration with POS systems.
