Common Mistakes to Avoid
Common failures across provider capabilities show up when teams pick based on UI deliverables alone, ignore integration governance, or underestimate the operating model needed for frequent safe releases.
Under-scoping OMS, ERP, and CRM integration ownership
Platforms that only cover storefront UI often break when order orchestration and back-office synchronization are unclear. Accenture, Cognizant, and Tata Consultancy Services handle OMS and ERP integration as part of managed ecommerce modernization, which helps avoid late rework when commerce operations expand beyond storefront rendering.
Choosing an agency that optimizes only design without instrumentation and measurement linkage
Conversion claims fail when analytics tracking and attribution are not treated as part of the build. Merkle ties storefront changes to performance reporting through tracking integration, while Distilled aligns front-end changes with analytics, experimentation, and search visibility goals.
Treating headless or composable modernization as a quick UI swap
Architecture changes require alignment across commerce workflows, catalog and cart behavior, and integration patterns. EPAM Systems and Publicis Sapient emphasize headless storefront architecture plus integration and governance, which is necessary to prevent rework when multi-system workflows change.
Expecting a lightweight engagement to carry enterprise-scale release governance
