Overview

Amazon's Prime Day remains one of the biggest selling opportunities of the year for third-party sellers. In 2024, independent sellers moved over 200 million items during the 48-hour event, underscoring just how much revenue is at stake. This guide breaks down the essential timelines, inventory strategies, shipping recommendations, and deal submission details that sellers need to prepare effectively for Prime Day 2025.

Key Points / What Sellers Need to Know

• Deal submissions open in early 2025 — Sellers can submit deals and promotions starting around May 5, 2025, with submissions closing six hours before the event ends. Lightning Deal scheduling closes around May 6, 2025, though some deal types can be submitted up to 12 hours before the event.
• Inventory deadlines are strict — Amazon requires FBA inventory to arrive at fulfillment centers well in advance. Amazon Warehousing and Distribution (AWD) shipments should arrive by approximately June 15, FBA shipments with minimal splits by June 9, and cost-optimized split shipments by June 18.
• Early shipping is essential — Delivery appointments should be scheduled at least seven days before the inventory deadlines. Sellers using Amazon's partnered carrier programs should have inventory ready for pickup 14 days ahead.
• Tracking and accuracy matter — Providing accurate box content information, tracking IDs, and carrier details helps Amazon process inventory faster and avoids manual processing fees.
• Leverage AWD for excess inventory — Sellers with four to six months of stock should consider Amazon Warehousing and Distribution to move excess inventory into the network and avoid storage issues.

Inventory Planning and Deadlines

Getting your products Prime badge-ready before the event requires careful planning around Amazon's receiving timelines. The key cutoff dates for 2025 are approximately June 15 for AWD shipments, June 9 for FBA shipments using the minimal shipment splits option, and June 18 for FBA shipments using cost-optimized shipment splits. These dates account for the time Amazon needs to receive, process, and position your inventory at fulfillment centers closest to customers. Sellers should build in buffer time for potential supply chain disruptions including supplier delays, carrier issues, port closures, and customs holdups. Booking carrier services well ahead of time is strongly recommended to avoid pickup delays that could cause you to miss these windows.
