Assemble, a Seattle-based digital agency specializing in retail tech, has worked exclusively with retailers since 2010 and has seen the benefits of adopting a composable commerce approach in their IT architecture. A composable approach allows for greater agility, faster innovation, and improved performance, enabling brands to adapt quickly to changing market demands. According to Assemble's CTO and VP of Design, Keith Karlick, one key area where retail brands find value is in the speed of business, particularly in fast-fashion industries where product lines are constantly updated. Composable architecture also enables retailers to integrate inventory management systems seamlessly across online and offline channels, reducing returns and improving customer experience. By adopting a modular software architecture, Assemble's clients can adopt new technologies quickly without worrying about platform changes, and the agency itself uses React View, Next.js, or Gatsby for most projects, leveraging Netlify for deployment due to its zero-dev-op capabilities. This approach also offers freedom of choice, allowing brands to experiment with new technologies without being locked into legacy systems. Assemble's experience highlights that composable architectures are not just for upstart companies but also for the biggest players in the world, enabling them to provide a truly excellent customer experience.
