Your On-Time Delivery score shows the percentage of seller-fulfilled packages that buyers received by the estimated delivery date. This number is based on confirmed tracking information. Since we use dispatch tracking to calculate on-time delivery, we also show the percentage of packages dispatched with tracking.
Buyers tell us that receiving their orders on time and having the ability to track their packages are important contributors to their overall satisfaction with an order. Our research shows that tracked orders have 60 percent fewer order defects and that tracking also helps reduce order inquiries from buyers.
Failure to meet Amazon's target for this metric generally does not result in the suspension of your selling account. However, it could cause negative feedback or claims, which could impact your selling account status.
