Retail & E-Commerce

Yes. We build retail and e-commerce mobile apps that connect directly to your existing POS and inventory systems, so stock counts stay accurate whether a sale happens in-store or in the app. During discovery, we map out exactly which systems your app needs to sync with before any design work starts, the same process we use for every New York build.

Retail and e-commerce mobile app development at New York App Devs runs on a fixed-price model agreed before work begins, so the number you sign off on is the number you pay. There's no published hourly rate, because every storefront, loyalty, or marketplace app is scoped around what your business actually needs. A simple loyalty app costs less than a full storefront rebuild with live inventory sync. You can get a real ballpark for your specific project through our Instant Estimate tool, which asks about platform, app type, complexity, and screen count. Getting an exact number always requires a short scoping call with our team.

There's no single timeline that fits every shopping or marketplace app, because scope varies too much project to project. What's fixed is the delivery rhythm: development runs in 1 to 2 week sprints, with a working build delivered incrementally so you can test the real app yourself every cycle. Once development wraps, deployment covers App Store and Google Play submission, screenshots, metadata, and handling any review rejection or resubmission, before your app goes live.

Yes. Our office is in Midtown Manhattan, at Americas Towers, 1177 6th Ave, 5th Floor, New York, NY 10036. We're a local, hands-on build partner, not a national call center or an offshore team with a local-sounding name. If you'd rather talk through your retail project in person, you can stop by, call, or book time with a real member of our New York team directly.

Three things: a fixed-price model with no surprise invoices, weekly sprint demos so you see a working storefront app every cycle instead of one reveal at the end, and 100% code ownership once the project's complete. We're also a DesignRush-recognized Top Mobile App Development Agency (2025), HIPAA and GDPR verified, and based in Midtown Manhattan, not an offshore team operating under a local-sounding name.
