Overview

Amazon has introduced FBA Same‑Day Delivery, a new fulfillment option that can get eligible items to customers in as little as five hours. The service is already live for more than 100,000 SKUs and does not carry any extra charge for sellers. Because fast shipping is a primary driver of conversion on the platform, the rollout creates a fresh competitive lever for FBA merchants.

Key Points

• Delivery window as short as 5 hours — Products that qualify can appear with a “Same‑Day” badge and reach buyers within a few hours of order placement.
• No extra seller fees — Participation uses the standard FBA fee schedule; Amazon has not added a premium charge for the accelerated service.
• Automatic enrollment — When an ASIN satisfies Amazon’s internal criteria, it is added to the program without any action required from the seller.
• Inventory repositioning by Amazon — Eligible stock is moved to fulfillment centers that are closer to high‑density customer zones, enabling the rapid dispatch.
• Badge awarded to the most competitive offer — The “fastest shipping” label appears on the offer with the best price, performance metrics, and inventory health, giving that seller heightened visibility.

How FBA Same‑Day Delivery Works

1. Eligibility assessment — Amazon evaluates each FBA‑eligible ASIN against size, weight, demand, and fulfillment‑center proximity rules. Example: a 12‑oz portable charger stored in a Midwest fulfillment hub meets the criteria and is flagged for same‑day service.
2. Inventory redistribution — Once an ASIN is approved, Amazon’s logistics network automatically transfers a portion of its stock to nearby fulfillment sites. Example: 500 units of a bestselling kitchen gadget are moved from a California warehouse to a Dallas hub to serve Texas customers faster.
3. Badge placement on the listing — The system identifies the seller with the most competitive price and performance for that ASIN and displays the “Same‑Day Delivery” badge beside the price.
