Headless E-Commerce with BigCommerce & Next.js
The Challenge
Expensive Plugin with Limited Functionality
An established online retailer was paying $70/month for a basic instant search plugin on their BigCommerce store. The plugin had limited customization options, slow performance, and didn't integrate well with their B2B quoting system. As their catalog grew to over 5,000 products, search performance degraded significantly, frustrating customers and impacting conversion rates.
Key Pain Points:
- •Monthly recurring cost of $840/year for basic functionality
- •Slow search performance with large product catalogs
- •No customization options for B2B requirements
- •Poor mobile experience
- •Limited integration with existing quoting workflows
The Solution
Custom Headless Commerce Platform
I built a fully custom headless e-commerce platform using Next.js and the BigCommerce API. The solution included native instant search powered by a custom search algorithm, server-side rendering for optimal performance, and tight integration with their B2B quoting system.
Implementation Approach:
- Architected headless Next.js frontend consuming BigCommerce APIs
- Built custom search indexing system with real-time updates
- Implemented instant search with autocomplete and filters
- Created custom B2B quoting interface integrated with search
- Optimized for mobile-first experience with responsive design
- Deployed on Vercel with edge caching for global performance
Technology Stack:
Results & Impact
The custom headless solution not only eliminated the monthly plugin cost but delivered a significantly better user experience. Search performance improved dramatically, mobile conversion rates increased by 32%, and the client gained complete control over their search UX. The system now handles 10,000+ products with instant results.
"We were skeptical about building custom when there were plugins available, but Kyle's solution paid for itself in the first year just in cost savings alone. The performance improvement has been incredible."
