There is a growing trend in composable commerce where leading e-commerce companies are starting with checkout optimization instead of migrating their storefront first to improve performance. The checkout process has been identified as a critical part of the e-commerce journey, and optimizing it can lead to significant revenue boosts. By starting with high-ROI projects like checkout flow optimization, teams can reduce scope, move quickly, scale, and leverage the composable approach across multiple brands. This approach is being adopted by agencies and large consumer brands, which are seeing tangible results in terms of conversion and revenue growth. By experimenting with different slices of experience, composable commerce solutions provide flexibility and allow brands to deliver a better customer experience.
