Headless Transformation for a Fashion Retailer
Industry: Apparel & Fashion
Client Overview: A mid-market fashion brand struggling with a slow, template-based site that couldn't keep up with their marketing campaigns and was delivering a poor mobile experience, leading to high cart abandonment rates.
"The new headless site is unbelievably fast. Our mobile conversion rate has skyrocketed, and we can finally execute the creative campaigns we've always dreamed of. Developers.dev was the perfect partner."
- Jenna Raynor, Head of E-commerce
Problem
The client's existing BigCommerce store was slow, inflexible, and failed to convert mobile visitors. They needed a high-performance, visually rich experience to compete in the crowded fashion market.
Key Challenges
- Page load speeds exceeding 5 seconds.
- Inability to create custom, content-rich landing pages.
- A clunky mobile UX causing a 75% bounce rate.
- Disconnected inventory with their physical stores.
Our Solution
We architected a headless solution using BigCommerce as the backend engine. We built a custom frontend with Next.js for server-side rendering and deployed it on Vercel for optimal performance and scalability.
- Developed a lightning-fast PWA-like storefront.
- Integrated a headless CMS (Contentful) for flexible content management.
- Designed a mobile-first, gesture-driven UI to boost engagement.
- Built a custom API to sync inventory with their in-store POS system.
Complex ERP Integration for a B2B Manufacturer
Industry: Industrial Manufacturing
Client Overview: A large B2B manufacturer using a legacy ordering system needed to launch a modern e-commerce portal for their distributors. The primary challenge was creating a real-time, two-way sync with their on-premise NetSuite ERP.
"Developers.dev didn't just build a website; they solved our core operational bottleneck. The real-time sync with NetSuite is flawless and has saved us hundreds of hours per month. It's a game-changer."
- Marcus Dyer, VP of Operations
Problem
The client's manual order processing was slow and error-prone. They needed a BigCommerce B2B Edition store that could handle complex customer-specific pricing, inventory levels, and order data, all synced in real-time with NetSuite.
Key Challenges
- Syncing thousands of SKUs and complex pricing tiers.
- Handling real-time inventory updates from multiple warehouses.
- Pushing complex B2B orders back into the ERP accurately.
- Ensuring the system was secure and reliable.
Our Solution
We developed a custom middleware application to act as a bridge between the BigCommerce API and the client's NetSuite instance. This solution handled data transformation, error logging, and queue management for maximum reliability.
- Utilized BigCommerce's Price Lists for customer-specific pricing.
- Built webhook-driven listeners for instant inventory and order updates.
- Created a custom dashboard for monitoring sync status and errors.
- Implemented robust security protocols for all data transfers.
Seamless Migration & Scaling for a D2C Brand

"The migration to BigCommerce was smoother than we ever imagined. We had our biggest sales day ever just two weeks after launch, and the site didn't even blink. The peace of mind is invaluable."
- Sophia Dalton, Founder & CEO
Problem
The client's WooCommerce site couldn't handle their traffic spikes, was becoming a security risk, and required constant plugin updates and maintenance. They needed a scalable, secure SaaS platform without sacrificing their brand's unique look and feel.
Key Challenges
- Migrating 10,000+ customers and 50,000+ orders without data loss.
- Preserving years of SEO authority and URL structures.
- Replicating complex subscription logic in BigCommerce.

Frequently Asked Questions
Have questions? We have answers. Here are some of the most common inquiries we receive about our BigCommerce development services.
BigCommerce offers a powerful balance of SaaS convenience and open-platform flexibility. It typically has a lower total cost of ownership than Magento (no hosting/maintenance overhead) and more native features for B2B and complex catalogs than Shopify Plus. Its API-first approach also makes it an excellent choice for modern headless builds.
We have a robust project management framework. You'll have a dedicated US-based or region-specific Project Manager, daily stand-ups, and access to collaboration tools like Slack, Jira, and Teams. Our CMMI Level 5 processes and rigorous, AI-assisted QA ensure code quality meets the highest standards.
Headless commerce decouples your frontend presentation layer (the "head") from your backend e-commerce engine (BigCommerce). You need it if your top priorities are lightning-fast site speed, complete design freedom, and the ability to deliver content to multiple channels (web, mobile apps, etc.) simultaneously. It's ideal for ambitious, experience-driven brands.
Absolutely. Our core strength is complex integrations. As long as your ERP has an accessible API, we can build custom middleware to facilitate seamless, real-time data exchange with BigCommerce for orders, customers, and inventory.
The 2-week paid trial allows you to work directly with one of our developers on a small, defined task. It's a low-risk way to experience our technical skills, communication, and process firsthand. You get tangible results and complete confidence before committing to a larger project. All work produced is yours to keep.
