E-commerce platforms that convert visitors into customers
Slow stores lose sales. That is the whole game in commerce. We build storefronts and marketplaces that stay fast when a flash sale doubles your traffic, handle the catalog and inventory and payment plumbing underneath, and actually turn browsers into buyers. Single-brand shop or a multi-vendor marketplace, we have built both.
E-commerce development challenges we solve
Performance at Scale
E-commerce platforms must handle traffic spikes during sales events without slowdowns. A 1-second delay in page load can reduce conversions by 7%.
Payment & Logistics Integration
Multiple payment gateways, shipping carriers, tax calculations, and inventory systems must work together reliably across regions.
Conversion Optimization
Every page must be optimized for conversion, with fast load times, intuitive navigation, one-click checkout, and personalized recommendations.

How we build your e-commerce product
Commerce Requirements Analysis
We map your product catalog structure, payment flows, shipping integrations, and conversion goals. Every eCommerce project starts with understanding your revenue model.
eCommerce Team Assigned
A senior team with headless commerce, payment gateway, and marketplace experience. Your team includes frontend, backend, and integration specialists.
Paid Pilot Sprint
We start on your actual store or marketplace project. You see our eCommerce architecture knowledge, payment integration skills, and UI performance expertise.
Build & Scale

Multi-vendor fulfillmentGeminate Solutions builds custom eCommerce software for online retailers, marketplace operators, and D2C brands. We partner on the build rather than renting out coders. Our headless commerce work covers product catalogs, multi-vendor marketplaces, inventory, and payment integrations with Stripe and PayPal. We have shipped stores that hold up when a sale event throws 10x normal traffic at them. Your dedicated eCommerce team gets scoped per engagement.
Common questions about e-commerce development
Can you build a custom e-commerce platform from scratch?
Yes. We build custom headless commerce platforms using Next.js and Node.js. This gives you full control over the shopping experience, unlike template-based solutions.
Do you integrate with existing e-commerce tools?
Yes. We integrate with Shopify, Stripe, PayPal, shipping carriers, ERP systems, and marketing platforms. We also build custom connectors for proprietary systems.
How do you handle high traffic during sales events?
CDN caching out front, server-side rendering, read replicas on the database, and infrastructure that scales itself when the crowd shows up. We have run stores through 10x spikes without the site falling over. The architecture is the part you do not see until the day you need it.
How much does eCommerce software development cost?
The build sets the price, not a flat menu. A simple custom store launches in 8-12 weeks at the lighter end. A multi-vendor marketplace sits in the middle. An enterprise platform with ERP integration is the heaviest lift. Catalog size, payment and shipping hookups, and your expected traffic peaks are what actually move the number. Maintenance is priced separately to the support level you want. You get firm figures for both build and upkeep on a free call before work begins.
Do you have PCI compliance experience for eCommerce?
Yes. Every eCommerce project we ship includes PCI DSS-compliant payment processing with tokenization, 3D Secure authentication, and fraud detection. We integrate with Stripe, PayPal, and regional payment providers.
Can you provide a dedicated eCommerce-experienced team?
Yes. We assign a dedicated eCommerce team scoped per engagement. Our engineers have built headless stores, marketplace platforms, and inventory systems. We start with a paid pilot sprint so you see the fit on your own store.
How long does it take to build a marketplace platform?
A basic two-sided marketplace takes 12-16 weeks. Adding vendor dashboards, commission management, and automated payouts extends to 16-24 weeks. We ship working vendor onboarding and checkout within the first 6 weeks.
What tech stack do you use for eCommerce projects?
We use React with Next.js for server-rendered storefronts, Node.js for backend APIs, PostgreSQL and Redis for data and caching, Elasticsearch for product search, and Stripe for payments. Cloudflare CDN handles global content delivery.
