Our Offerings
E-Commerce Development Services We Provide
Shopify & Shopify Plus Development
Custom themes, private apps, and Hydrogen headless builds for merchants who have outgrown off-the-shelf templates. We integrate ERPs, 3PLs, and subscription engines without breaking your upgrade path.
Headless Commerce
Decoupled storefronts pairing commerce engines like Shopify, Magento, or commercetools with lightning-fast React front ends. Headless clients see page loads under 1.5 seconds and conversion lifts of 15-25%.
B2B Commerce Portals
Wholesale platforms with tiered pricing, quote-to-order workflows, credit limits, and punchout catalog support. We digitize the rep-and-spreadsheet ordering process into self-service that runs around the clock.
Payment & Checkout Engineering
PCI DSS-compliant integrations with Stripe, Razorpay, PayPal, and Adyen, including one-click checkout, wallets, and BNPL options. Optimized checkouts routinely cut cart abandonment by 15-20%.
Marketplace Development
Multi-vendor marketplaces with seller onboarding, commission management, split payments, and dispute workflows. We have launched marketplaces handling 50,000+ SKUs and thousands of daily orders.

“They took over a half-finished React Native app another agency had abandoned, stabilized it in six weeks, and shipped the features our investors were waiting on. The code audit they delivered in week one was worth the engagement on its own.”
“As a Mumbai-based startup we evaluated a dozen agencies before choosing Devlex for our logistics SaaS. They built the MVP in ten weeks, helped us close our seed round with a working product, and now run our entire engineering function.”
“Devlex designed and built our analytics dashboard handling over 2 million events a day, with role-based access our enterprise clients demanded. Their UX work alone lifted our trial-to-paid conversion by 22%.”
FAQ
E-Commerce Development — FAQs
Everything you need to know before starting your project. Still have questions? Talk to our team.
B2C storefronts, B2B wholesale portals, multi-vendor marketplaces, subscription commerce, and headless builds. We work across Shopify, Magento (Adobe Commerce), WooCommerce, and fully custom stacks — the right platform depends on your catalog size, customization needs, and growth plans.
A Shopify store with a custom theme launches in 4-8 weeks; a custom or headless build takes 3-6 months. Marketplace platforms with vendor management typically need 5-8 months including payment compliance work.
Shopify builds start around $10,000-$30,000, custom platforms range $30,000-$100,000+, and marketplaces typically start at $50,000. Ongoing costs include hosting ($100-$1,000/month at scale) and payment processing fees of 2-3% per transaction.
Absolutely — all custom code, themes, and integrations are yours with full IP transfer, and your customer data always lives in accounts you control. We never lock clients into proprietary tooling.
We run load tests simulating 5-10x normal traffic before Black Friday and festival seasons, and our 24/7 support team monitors uptime with sub-15-minute alert response during peak windows. Most clients keep a retainer covering performance tuning and rapid fixes year-round.
Yes — we migrate products, customers, order history, and SEO rankings with full 301 redirect mapping and zero data loss. A typical migration of a 5,000-SKU catalog takes 6-10 weeks, and we run both platforms in parallel until the new store is verified.
