eCommerce Software Development Company in New York, built to ship.

A slow checkout is a lost sale. For online retailers, D2C brands, and marketplace operators, we design and build custom storefronts that load fast and convert, then connect them to the multi-vendor logic, inventory, payment, and fulfillment systems that quietly run the business behind the buy button. New York runs on Eastern Time, which is 9.5 hours behind India Standard Time, so the practical daily overlap is your morning India team meeting your end of business day in NY, which we run as an async-first workflow with a fixed live window for standups and reviews.

Free scope and estimate in 24 hours. No pitch, no obligation. You own the code and IP, and we sign an NDA on request. Privacy Policy.

Compliance in United States

How does eCommerce Software Development stay compliant with CCPA / CPRA in New York?

New York companies build under a sector and state patchwork led by California's CCPA and CPRA, overseen by the California Privacy Protection Agency, alongside state AGs and the FTC. We design every ecommerce engagement to respect those rules from day one, not as a checklist bolted on at the end. There is no single federal privacy law, so we map your build to the states you operate in, plus HIPAA for health data or PCI DSS for payments where they apply.

Who regulates you

the California Privacy Protection Agency, alongside state AGs and the FTC. regulated US products often need HIPAA, SOC 2, or PCI DSS controls, which we scope into the architecture rather than retrofit.

Where your data lives

You pick the hosting region. When residency rules or a United States contract require it, we deploy inside your jurisdiction and you hold the cloud accounts.

What you own

100% of the source code and IP, transferred under contract, with an NDA and a data processing agreement signed before anything is shared.

Proof we can do this at scale: the products we have shipped run at 250K+ daily active users and have handled 10M+ requests per minute, across 50+ products rated 4.9 stars over 24+ client projects. Security and data handling are part of how we build, not an afterthought.

FAQ

eCommerce Software Development in New York, answered

Can you build a custom eCommerce platform instead of using a template?
Custom is where we are strongest. We build headless commerce platforms with Next.js and Node.js, which gives you control over the storefront, checkout, and data that template tools cannot match. We also integrate with Shopify and other systems when a custom layer on top makes more sense for your roadmap.
How do you keep a store fast during sales events and traffic spikes?
Peak load is a design constraint, not a surprise. We architect for it with CDN caching, server-side rendering, database read replicas, and auto-scaling infrastructure. Our team load-tests against your expected concurrency before launch so flash sales and seasonal peaks do not degrade checkout.
Do you have PCI compliance experience for payment processing?
Tokenization and 3D Secure carry the load here. We ship PCI DSS-compliant checkout with fraud detection, and card data is handled through certified gateways such as Stripe and PayPal so sensitive details never touch your own servers.
How do working hours line up between a New York team and an India based development partner?
India Standard Time is 9.5 hours ahead of New York Eastern Time, so the natural overlap is your morning against our late afternoon. We schedule live standups and demos inside that window and run the rest of the build async, which means work continues on your project after your office closes and you wake up to progress.
Is offshore software development from India more cost effective than hiring locally in New York?
New York carries some of the highest engineering salaries and office costs in the United States, so partnering with an India based team like Geminate Solutions typically gives you senior product talent at a meaningfully lower total cost. We scope the exact figure for your project on a short call so it maps to your real requirements.
How do you handle CCPA / CPRA and data protection for New York clients?
New York businesses fall under a sector and state patchwork led by California's CCPA and CPRA, overseen by the California Privacy Protection Agency, alongside state AGs and the FTC. There is no single federal privacy law, so we map your build to the states you operate in, plus HIPAA for health data or PCI DSS for payments where they apply. Before any data is shared we sign an NDA and a data processing agreement, and regulated US products often need HIPAA, SOC 2, or PCI DSS controls, which we scope into the architecture rather than retrofit.
Where will our data and code be hosted if we build with you from New York?
You choose the region. We default to a cloud setup that satisfies CCPA / CPRA obligations, and when residency rules or a United States contract require it, we host inside your jurisdiction. You keep full ownership of the source code, the data, and the infrastructure accounts at all times.
How much does eCommerce Software Development cost in New York?
Every ecommerce project is scoped on a free call rather than sold as a fixed package, and most engagements start with a paid pilot sprint so you see the work before you commit. You get a clear number in USD before anything starts.
Do we own the code?
Yes, completely. The code, the project, and the content are handed to you. You hold the keys, not us. We sign an NDA before you share anything.
How long does it take?
Most builds go live in two to four weeks. Larger products with a custom backend or migration take longer, and you get a firm timeline before any work begins.
