Why 64labs leads the pack in enterprise composable builds on Salesforce Commerce Cloud

Building Composable Storefronts for Global Brands: The 64labs Perspective

Implementing the Salesforce Commerce Cloud PWA Kit Composable Storefront for major multi-region retailers - such as Horizon Hobby (US, UK, Europe), Aritzia (US, Canada), e.l.f. Beauty (global), Callaway Golf (US, UK, EU), Sweaty Betty (US, UK), and Moncler (US, Europe) - has provided 64labs with deep insight into the real-world complexities and rewards of composable commerce. 

Here are our experiences tackling challenges that you may think are the domain of the bigger consultants in the space.

Global Complexity and Localization

Multi-region launches are significantly more complex than single locale rollouts. Each market brings its own requirements around currency, taxes, languages, product catalogs, and fulfillment workflows. For example, supporting Horizon Hobby’s diverse multi-brand US, UK, and EU customers meant building storefronts with tailored content, payment options, and regional logistics, managed by a high-performance frontend able to localize rapidly and stay performant across geographies.

The Challenge of Seamless Headless Integration

PWA Kit enables a fast, responsive headless experience, but decoupling the frontend from legacy Salesforce templates like SiteGenesis and SFRA means e-commerce teams must re-engineer core workflows (content orchestration, promotions, and personalization) using modern APIs. Our Accelerator helps bridge this gap, but the learning curve for retailer tech teams is steep: optimizing data sync, managing distributed caches, and ensuring business users retain control over digital merchandising are ongoing challenges, especially when transitioning multiple legacy systems into a single composable experience. 

Performance, Scalability, and Reliability

Operating sites across continents means performance optimizations are mandatory. Deploying the PWA frontend near Salesforce’s data centers for each region keeps sites fast and reliable, minimizing latency for users in North America, Europe, and beyond. Callaway Golf (which was a Vercel-NextJS build) and Sweaty Betty relied on 64labs to monitor, tune, and upgrade their storefronts to maximize speed, stability, and conversion rates at launches during peak shopping periods, supported by dynamic scaling in Salesforce’s managed runtime or Vercel’s infrastructure. There’s a lot to understand.

Governance and Collaboration

A multi-brand or multi-country rollout involves complex stakeholder dynamics. Each retailer division or geo needs some autonomy while benefiting from shared components and architecture for long-term maintainability. For Moncler, empowering distributed merchandising and content teams to personalize each market’s storefront, without sacrificing technical standards or conversion best practices, has been key to driving global e-commerce growth.

Learning Curve: Enabling Teams for Success

Transitioning from legacy templates to PWA Kit requires upskilling: dev teams must pivot from monolithic approaches to API-first thinking, while marketers need new tools for content orchestration outside Business Manager’s clunky but familiar interface. Our Accelerator was built to flatten this curve, providing high-quality scaffolding, reusable modules, and training, so merchants and marketers can drive timely changes without relying exclusively on technical resources. To deliver enterprise-wide benefits there has to be change and learning across the enterprise to understand and exploit the opportunities of the new stack effectively.

Real-World Takeaways

Implementing PWA Kit for global retailers has been a test-and-learn journey. Early rollouts like Sweaty Betty’s US storefront proved that composable approaches deliver measurable performance and conversion gains when agile teams, best-practice frameworks, and iterative deployment are combined. Brands like e.l.f. Beauty and Callaway Golf continue to refine and expand their composable strategy, integrating loyalty, content, and search for ever-more personalized customer journeys.

The challenges of scaling PWA Kit for global retailers are significant - from technical integration and localization to stakeholder governance and organizational learning. But with the right approach, composable commerce is not just a technology shift - it’s an opportunity for brands to deliver world-class, market-tailored digital experiences at speed and scale. 

For 64labs, every launch brings new lessons, and each success reaffirms the value of deep technical expertise, collaborative partnership, and relentless focus on merchant empowerment. For enterprise scale composable storefront launches on Salesforce, 64labs is probably the most experienced implementer in the world.
