Outdoor retailer replaces legacy system with modern, headless architecture to improve scalability, flexibility and customer experience
AUSTIN, Texas, April 20, 2026 (GLOBE NEWSWIRE) -- Commerce (Nasdaq: CMRC), an open, intelligent ecosystem of technology solutions and the parent company of leading ecommerce platform BigCommerce, today announced that Mountain Warehouse, a global outdoor clothing and equipment retailer, has launched a new composable ecommerce store powered by BigCommerce.
The new website replaces a decade-old custom-built system, enabling Mountain Warehouse to scale more efficiently, reduce operational complexity and accelerate innovation across its global ecommerce operations.
Founded in 1997, Mountain Warehouse operates more than 400 stores worldwide and serves over 5 million customers across key markets including the UK, U.S., Canada, Europe, Australia and New Zealand. The company designs and produces the majority of its products in-house, offering affordable outdoor apparel and equipment for the whole family.
“Moving away from our legacy platform was critical to unlocking the next phase of Mountain Warehouse’s growth,” said Simon Neale, Chief Technology Officer at Mountain Warehouse. “With BigCommerce, we now have the flexibility to innovate faster, integrate best-of-breed technologies and focus our engineering efforts on delivering better customer experiences rather than maintaining core infrastructure.”
From Legacy Constraints to Composable Flexibility
Mountain Warehouse’s previous ecommerce platform had become increasingly difficult to scale, with significant development resources required to maintain and support aging infrastructure. The business also faced limitations around speed to market, security and the ability to experiment with modern technologies.
By adopting a composable, headless architecture built on BigCommerce, Mountain Warehouse can now:
- Accelerate time-to-market for new features and initiatives
- Reduce reliance on maintaining custom core systems
- Improve platform security, reliability and compliance
- Enable flexible integration with third-party and in-house solutions
Modern Tech Stack Enables Best-of-Breed Approach
Mountain Warehouse’s new ecommerce experience is powered by a composable technology stack, including BigCommerce as the core commerce engine alongside:
- BigCommerce’s Catalyst frontend deployed on Vercel
- Contentful for content management
- Algolia for search and personalization
- Stripe, PayPal, Apple Pay and Google Pay for payments
- Dotdigital for marketing automation
This architecture enables Mountain Warehouse to adopt a best-of-breed approach while integrating custom middleware to manage inventory, pricing, customer data and shipping.
Built to Support Complex Global Operations
The implementation included several advanced capabilities tailored to Mountain Warehouse’s business model, including:
- Custom checkout experience supporting gift cards and multiple payment methods
- Multi-location inventory management and click-and-collect functionality
- Complex order handling, including split shipments and marketplace workflows
- Address lookup and validation integrations
- Support for bundled products and digital gift cards
“Mountain Warehouse’s launch demonstrates how enterprise retailers can move beyond the limitations of legacy systems,” said Andrew Norman, senior vice president and general manager of international. “With a composable foundation, they’re able to innovate faster, scale globally and deliver more seamless customer experiences.”
With its new platform in place, Mountain Warehouse is now positioned to continuously evolve its ecommerce experience, test new capabilities and scale efficiently as demand grows.
The composable approach also enables internal teams to focus on building differentiated features while leveraging third-party solutions for core commerce functionality.
