Delivery Promise Accuracy (DPA):

A key operational metric that measures the percentage of customer orders delivered within the timeframe promised at checkout or order confirmation. DPA reflects a brand’s ability to meet its stated delivery commitments, directly impacting customer satisfaction, marketplace ranking, and seller reputation.

High DPA (e.g., above 98%) indicates that logistics, inventory management, and carrier integrations are functioning reliably, and that customers are receiving their orders as expected. Low DPA may point to issues such as inaccurate stock levels, fulfilment delays, carrier disruptions, or unrealistic delivery estimates.

eCommerce and marketplace teams use DPA to monitor and improve the reliability of their order fulfilment processes. Tracking DPA helps identify weak points in the supply chain, supports proactive communication with customers, and can be used to set service level agreements (SLAs) with partners and carriers. In many marketplaces, maintaining a high DPA is essential for securing premium placement, avoiding penalties, and building long-term customer trust.
