Stop fitting your vision into a template.Let's build the exact e-commerce platform your business deserves.
The global e-commerce market is a titan, but off-the-shelf solutions like Shopify can feel restrictive. They force you into their ecosystem, limit your control, and chip away at your profits with transaction fees. It's time to break free. We build custom, scalable, and secure e-commerce platforms that give you complete ownership, endless customization, and the power to dictate your own future—without the recurring monthly fees eating into your success.

Proven Results: Our E-commerce Success Stories
Client Overview
Our client is a multi-billion dollar manufacturing company with a complex global distribution network. They relied on manual, email-based ordering processes which were slow, error-prone, and lacked visibility for their B2B customers.
The Challenge
They needed a robust, secure B2B e-commerce portal that could handle complex pricing tiers, integrate with their existing SAP ERP system, and provide a seamless self-service experience for their distributors.
- Integration with a legacy SAP ERP for real-time inventory and pricing.
- Handling of customer-specific, tiered pricing and bulk order discounts.
- Providing distributors with self-service access to order history and tracking.
- Ensuring enterprise-grade security for sensitive business data.
Our AI-Enabled Solution
We developed a custom B2B commerce platform built on a microservices architecture. The solution provided a secure, intuitive portal for distributors to place and manage orders 24/7.
- Developed a custom middleware for real-time, bi-directional synchronization with SAP.
- Engineered a complex rules engine to manage thousands of unique pricing structures.
- Built a comprehensive distributor dashboard for order management and reporting.
- Implemented an AI-powered recommendation engine that suggested complementary products, increasing AOV.
Client Overview
The client envisioned a platform similar to Etsy but focused exclusively on high-end, independent fashion. They needed a system that could empower individual designers with their own storefronts while maintaining a cohesive brand experience for shoppers.
The Challenge
The core challenge was building a multi-tenant architecture that was both easy for non-technical vendors to use and powerful enough to handle complex commission structures, shipping logistics, and payouts.
- Creating a simple, intuitive onboarding and product management system for vendors.
- Automating commission calculations and payouts for hundreds of vendors.
- Integrating multiple shipping carriers and providing unified order tracking.
- Ensuring a high-quality, curated shopping experience for customers.
Our AI-Enabled Solution
We built a scalable multi-vendor marketplace from the ground up, focusing on the vendor experience. The platform included individual vendor dashboards, automated payment splitting, and centralized marketing tools.
- Designed a step-by-step vendor onboarding wizard that simplified store setup.
- Integrated Stripe Connect to automate complex commission splits and payouts.
- Developed a unified admin panel for the client to oversee all vendors, products, and orders.
- Used AI-based image recognition to auto-tag product uploads, improving searchability and saving vendors time.
Client Overview
The client, a popular CPG brand, was struggling with a slow, monolithic e-commerce site that offered a poor mobile experience and was difficult to update. They wanted to re-platform to a modern, flexible architecture.
The Challenge
The goal was to decouple the front-end presentation layer from the back-end commerce logic (a "headless" approach) to achieve lightning-fast performance and enable content delivery to future channels like mobile apps and smart devices.
- Migrating thousands of products and customer records with zero downtime.
- Building a custom front-end using a modern JavaScript framework (React).
- Ensuring sub-second page loads to improve SEO and user experience.
- Creating a robust set of APIs to power future applications.
Our AI-Enabled Solution
We engineered a complete headless commerce solution. The back-end was built as a set of powerful APIs, while the front-end was a blazing-fast Progressive Web App (PWA) built with Next.js.
- Used a content delivery network (CDN) and advanced caching for unparalleled speed.
- Developed a custom CMS integration, allowing their marketing team to easily update content.
- The PWA provided an app-like experience on mobile, dramatically boosting conversions.
- The API-first design made it simple to later launch an integrated subscription box service.

Frequently Asked Questions
While Shopify Plus is a powerful tool, a custom platform offers key advantages for scaling businesses: 1) No Transaction Fees: You keep 100% of your revenue. 2) Complete Customization: You're not limited by themes or app ecosystems; we can build any feature or integration you need. 3) Full IP Ownership: You own the code and the asset, which increases your company's valuation. 4) Deeper Integration: We can build direct, deeply-integrated connections to your core business systems (ERP, WMS) that are far more robust than standard apps.
The timeline varies based on complexity. A Minimum Viable Product (MVP) with core e-commerce functionality can typically be launched in 3-4 months. A more complex platform with advanced features and third-party integrations might take 6-9 months. An enterprise-level solution with multi-vendor capabilities and extensive customization could take 9-12+ months. We prioritize a phased approach, allowing you to get to market quickly and iterate.
Security is our top priority. Our development process is governed by our ISO 27001 and SOC 2 certifications. We follow OWASP Top 10 security practices, implement secure coding standards, conduct regular vulnerability scanning and penetration testing, and ensure all data is encrypted in transit and at rest. For payments, we integrate with PCI DSS compliant gateways to ensure sensitive financial data never touches your servers.
Absolutely. We design for scale from day one. By using modern cloud infrastructure (like AWS or Google Cloud), auto-scaling groups, load balancing, and content delivery networks (CDNs), we build platforms that can handle sudden traffic spikes without compromising performance. We conduct rigorous load and stress testing to simulate high-traffic events before launch.
We offer comprehensive, ongoing support and maintenance plans to ensure your platform remains secure, updated, and optimized. Our services include 24x7 monitoring, regular security patching, performance optimization, and a dedicated support team for bug fixes and technical assistance. We also offer retainers for ongoing feature development and strategic growth initiatives.
