Amazon Business orders fulfilled by merchants are now evaluated on whether they arrive while the customer’s business is open
⤷ Not just by the promised delivery date.
→ What Changed
Starting September 30, U.S. sellers must maintain a Business Hour Delivery Rate of at least 90% across seller-fulfilled Amazon Business orders.
Sellers below the threshold receive a warning.
If performance remains below 90% after October 30, their seller-fulfilled offers may be deactivated for Amazon Business customers.
→ Why It Matters
An order can arrive on time and still hurt the metric if it is delivered outside the buyer’s business hours.
This adds another carrier and shipping-configuration consideration for FBM sellers.
→ What Is Not Changing
FBA offers and Amazon retail offer eligibility are not affected.
→ What to Do Now. Immediate operational check.
FBM sellers serving Amazon Business customers should review their Business Hour Delivery Rate in Account Health and verify that shipping settings and carrier services support business-hour delivery.
→ Bigger Picture Signal
Amazon is adding more delivery-performance requirements tied to the customer’s actual receiving experience.
