Storefronts that load fast, and back offices that stop retyping orders
WeBuildStack is a remote-first software development company in Bengaluru, India, that builds web and mobile applications and the cloud behind them. For storefronts, marketplaces and order management with stock, payments and couriers kept in sync: a written quote within 48 hours and an MVP in six weeks with deployment included, with team hours set to your timezone. 15+ engineers, 100+ projects.
Fast storefronts that rank, checkouts that convert, and back-office systems that stop your team copying orders between spreadsheets.
Where e-commerce projects usually stall
Stock counts that drift between Shopify, marketplace listings and the warehouse until a bestseller is oversold.
COD parcels that come back undelivered and quietly eat margin because nobody flags risky pincodes before dispatch.
Product pages that fail mobile Core Web Vitals and lose rankings to slower competitors with better structured data.

E-commerce software: your questions

Yes, for storefronts, marketplaces and order management with stock, payments and couriers kept in sync. A written scope and fixed quote within 48 hours, an MVP in six weeks with deployment included, the standards designed in from week one, and a tech lead reviewing every pull request from Bengaluru, India.
Usually stay. Shopify or Medusa handles catalogue and checkout well; we go custom only for what differentiates you, such as bundling rules, B2B price lists or a marketplace layer.
Yes. We move products, customers and order history, map every old URL to its new one with 301 redirects, and watch indexed pages in Search Console after launch.
COD gets its own rules: pincode checks, OTP confirmation or partial prepayment. Return requests go straight into your courier’s reverse-pickup API instead of an inbox.
