Amazon Prime Day Preparation: The 8-Week Seller Checklist

Amazon Prime Day (typically held in mid-July, with an occasional second event in October) generates 2–4 days of sales volume that for many sellers exceeds their entire preceding month. But the preparation timelines are non-negotiable: Lightning Deal submissions close 6–8 weeks before the event. Inventory must arrive at Amazon fulfillment centers before Amazon's FBA receiving cutoff (typically 2–3 weeks before the event starts). Listing optimization changes take weeks to impact organic rank.

Sellers who prepare on time can 3–5x their daily revenue during Prime Day. Sellers who miss the Lightning Deal submission window or understock inventory simply watch competitors capture the traffic spike they cannot monetize.

This article provides a week-by-week preparation framework based on the typical Prime Day timeline (assuming a mid-July Prime Day). Dates shift by a few weeks year-to-year — check Amazon's official Prime Day seller news page in Seller Central for the specific submission deadlines when announced.

Week 8 — Submit Lightning Deals and 7-Day Deals: Amazon opens deal submissions approximately 8 weeks before Prime Day. Go to Seller Central → Advertising → Deals → Create a Deal. Eligible products (4+ stars, Prime-eligible, with sales history) will appear. Submit for your top-performing ASINs — deals on products with limited history are unlikely to be approved. Budget the submission fee ($150–500+ during Prime Day; check current rates).

Week 7 — Set up Prime Exclusive Discounts: these require no submission fee and can be activated closer to the event, but setting them up early ensures they're live on Prime Day. Minimum discount: typically 10% below regular price. Prime Exclusive Discounts display a special badge in search results — activating them before the Lightning Deal window boosts pre-Prime Day visibility.

Week 6 — Place inventory order for Prime Day replenishment: calculate your projected Prime Day demand (typically 3–5x average daily units × event duration in days + buffer). Add this to your normal replenishment order. This inventory must arrive at Amazon FBA by Amazon's Prime Day cutoff — typically 2–3 weeks before the event. Sea freight from Taiwan takes 5–6 weeks to Amazon FBA; order now if shipping by sea.

Week 5 — Optimize listings for Prime Day conversion: update main images, A+ Content, and titles on your Prime Day hero products. Changes made at week 5 have time to be indexed and impact conversion before the event. Audit your top-5 keywords' current organic rank — if you're on page 2, increase PPC bids now to drive rank improvements before Prime Day traffic arrives.

Week 4 — Pre-build PPC campaigns: create dedicated Prime Day campaigns with higher budgets and more aggressive bids. Amazon's CPC rates spike during Prime Day as sellers compete for clicks — if you wait until Prime Day to increase budgets, you'll hit budget caps during peak hours. Pre-set Prime Day campaigns to start at midnight on Day 1 with 2–3x normal budget.

Week 3 — Verify inventory is on the way or received: check FBA shipment status for your Prime Day inventory order. If there are receiving delays, investigate and escalate. A stockout during Prime Day is catastrophic — you cannot recover missed Prime Day sales.

Week 2 — Review deal eligibility in Seller Central: go to Advertising → Deals to verify your submitted Lightning Deals and 7-Day Deals are still scheduled and not rejected. Amazon can reject deals up to 24 hours before the event for eligibility violations (price changes, inventory shortfalls, rating drops). Fix any issues immediately.

Week 1 — Customer service preparation: Prime Day generates 3–5x normal customer inquiry volume. Ensure buyer-seller message notifications are active. If possible, have extra support coverage during the event days.

Day of — Monitor performance hourly: check your Prime Day campaign spend vs budget. Adjust bids if you're running out of budget before peak hours (evening in your target timezone tends to be highest conversion). If a deal runs out of reserved inventory faster than expected, check if you can increase the quantity allocation.

Post-Prime Day — Maintain organic rank: the sales velocity spike during Prime Day boosts BSR and organic rank. Maintain elevated (though reduced from Prime Day levels) PPC spend for 1–2 weeks after the event to lock in rank improvements. Immediately restock if inventory depleted — Prime Day-boosted rank evaporates within days of a stockout.
