eCommerce Software Development Company in Austin, 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. Austin runs on US Central Time, which is 10.5 hours behind India Standard Time, so the live daily overlap is short and sits at your early morning against our evening, which we structure as an async-first delivery model with a fixed overlap 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.

Austin market

Austin has become one of the top five venture capital cities in the United States, with a fast moving scene spanning enterprise software, semiconductors, space and defense, clean energy, and health tech. The pull of companies like Tesla, Oracle, and a deep space cluster around Texas keeps demand high for custom software, data platforms, and connected products. Geminate Solutions works with Austin startups and scaleups that want to move fast and need an engineering partner to extend their build capacity.

Local signal: Austin startups raised roughly 8 billion USD in venture capital in 2025, a record that placed the city among the top five US metros for VC, with funding driven by AI, space, defense, energy, and advanced manufacturing.

Compliance in United States

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

Austin 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 Austin, 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.
What is the working hour overlap between Austin and an India based software team?
Austin sits on Central Time, 10.5 hours behind India Standard Time, so the live overlap is modest and falls in your early morning. We design the engagement async-first, hold demos and standups in a fixed daily window, and use the time difference so your project keeps moving overnight Central time.
How does offshore development with an India based partner compare on cost to hiring engineers in Austin?
Austin engineering salaries have climbed sharply as the city became a major tech hub, so an India based partner like Geminate Solutions usually delivers senior product engineering at a lower total cost than building the same team locally. We scope the exact cost for your roadmap on a quick call.
How do you handle CCPA / CPRA and data protection for Austin clients?
Austin 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 Austin?
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 Austin?
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.
