Ecommerce app development services engineered to convert, scale, and survive Black Friday.

End-to-end ecommerce mobile app development — B2C, B2B, D2C, and multi-vendor marketplace apps. We build on every major commerce backend (Shopify, Shopify Plus, Magento 2, WooCommerce, Saleor, Medusa, commercetools, Odoo eCommerce), integrate every major payment gateway (Stripe, Adyen, Razorpay, Paytm, PayPal, Apple Pay, Google Pay, BNPL), and layer in AI recommendations, AR product try-on, lifecycle marketing, and fulfilment integration. Engagements are fixed-price builds, dedicated commerce teams, or replatform sprints.

Ecommerce app development cost depends on catalog complexity, B2C vs B2B vs marketplace, payment gateways by geography, and backend choice. As a guide: a focused D2C mobile app on top of an existing Shopify store typically lands between $25K–$55K. A multi-vendor marketplace app starts around $70K and scales with vendor and feature complexity. Headless replatforms with mobile-first design land in $80K–$200K depending on catalog migration scope.

Shopify Storefront API is the right default if you already run a Shopify store and want to ship fast — we can build a mobile app on top in 6–10 weeks. Headless (Saleor, Medusa, Shopify Hydrogen, commercetools) makes sense when you need full control over the catalog model, complex B2B rules, or multi-brand setups. Custom-built backends are reserved for marketplaces and enterprise B2B with workflows no off-the-shelf platform supports.

A D2C mobile app on top of an existing commerce backend typically ships in 8–12 weeks. A full B2B or marketplace app with vendor onboarding, commission engines, and split payouts lands in 14–20 weeks. We commit to a milestone schedule before the first sprint and demo a shoppable build every two weeks.

We've integrated Stripe, Stripe Connect (for marketplaces), Adyen, Braintree, Square, Razorpay, Paytm, PhonePe, PayU, CCAvenue, PayPal, Worldpay, Apple Pay, Google Pay, buy-now-pay-later providers (Affirm, Klarna, Afterpay, Simpl), and crypto wallets. We design every payment integration with PCI-DSS scope reduction in mind — tokenization, hosted fields, and 3-D Secure 2 where required by region.

Yes — and this is one of our strongest differentiators. We've built real-time inventory sync layers for Odoo POS, ERPNext, Zoho Inventory, Shopify, and custom WMS systems. Typical pattern: webhook-driven sync for fast updates, periodic reconciliation jobs to catch drift, and an admin dashboard to monitor sync health. Multi-warehouse routing and click-and-collect (BOPIS) included.

Yes. AR product try-on uses ARKit on iOS and ARCore on Android — common in fashion (glasses, makeup), home goods (furniture placement), and beauty. AI recommendations are built on a hybrid collaborative + content-based engine, plus optional LLM-powered conversational shopping. These features typically lift conversion 15–30% when designed against the right merchandising goal.

Yes. Multi-vendor marketplaces are one of our specialties. We handle vendor onboarding and KYC, commission rules engines (flat, tiered, category-based), Stripe Connect for split payouts, vendor-side dashboards (often a separate companion app), order routing per vendor, dispute resolution workflows, and review / rating moderation. Typical timeline: 16–22 weeks from kickoff to launch with the first 10 vendors onboarded.

Peak-event readiness is built in. Pre-event load testing with k6 or Locust, autoscaling rules on the backend, queue patterns for checkout under load, server-side conversion (CAPI) for ad reliability when iOS ATT impacts pixel tracking, real-time order monitoring dashboards, and a 72-hour war-room rotation after every major sale event. We've kept apps standing through Black Friday traffic spikes 10× normal volume.
