Common Mistakes to Avoid
The reviewed providers show recurring pitfalls that occur when internal ownership, governance, and system inputs do not match the provider’s delivery model.
Picking a strategy-first provider when storefront changes require heavy internal development capacity
Merkle’s on-site changes can depend on client development capacity, which makes misalignment a common source of delays. EPAM Continuum modernization work also requires significant business and data owner input, which can stall engineering-heavy delivery when stakeholders cannot provide fast turnaround.
Using a provider that is not built to orchestrate media-to-site journeys
A commerce team expecting retail media orchestration should avoid treating dentsu commerce and WPP Open Network as interchangeable with single-platform execution providers. dentsu commerce and WPP Open Network explicitly connect retail media activation workflows to onsite conversion testing and merchandising measurement.
Underestimating governance overhead in multi-stakeholder enterprise programs
Publicis Sapient and Accenture Song can feel heavy for small teams because platform changes require cross-system alignment and longer planning cycles. Valtech and EPAM Continuum also require tight stakeholder coordination and clear scope to avoid schedule churn in complex integrations.
Assuming deep platform engineering is optional when architecture and integrations drive outcomes
EPAM Continuum emphasizes composable modernization and reusable service APIs, which makes architecture and event instrumentation foundational rather than optional. Kibo Commerce is also integration-centric for inventory and pricing data consistency, so teams with messy upstream systems can see operational friction even when checkout execution is strong.
