Seasonal sellers make most of their year in a few weeks, which is exactly when Amazon tightens capacity, raises storage fees and slows receiving. We stage peak inventory upstream before the rush and feed FBA in planned waves timed to Amazon's holiday inbound deadlines, with the remainder ready to ship through other channels or return to storage after the season.
Why Q4 is different at Amazon
Q4 is different at Amazon because three things happen at once: demand climbs, monthly storage fees rise for October through December, and receiving gets slower as every seller ships in at the same time. Capacity limits for the season can also land lower than you hoped, leaving inventory you have already paid for without a home inside FBA.
Amazon publishes recommended holiday inbound dates each year. Missing them often means units arrive after the peak they were bought for. Staging stock upstream lets you ship to Amazon early in planned waves and still hold back depth for late-season replenishment.
Building a peak replenishment plan
A peak replenishment plan starts with a forecast by SKU and works backward from Amazon's receiving window. For each wave we set a ship date, the days of cover it needs to deliver and the share of your capacity limit it will use, then size later waves from actual sell-through rather than the original forecast.
Prime Day and other tentpole events follow the same logic on a shorter clock. Bundles and holiday kits can be assembled upstream before the season, labeled as sets and held until the right wave. Wave planning keeps you inside your limits, protects in-stock rate during the busiest weeks and avoids sending surplus into peak-rate storage.
After the peak
After the peak, the goal is to stop paying Amazon to hold what did not sell. Seasonal SKUs left in FBA in January start aging toward surcharges, and you may want the space back for spring launches. Because most depth stayed upstream, there is usually less to unwind.
For what is left inside Amazon, removal orders can bring units back for inspection, re-prep and storage until next season, or for sale through wholesale and off-price channels. Units held upstream simply stay put. The result is a cleaner start to the new year and capacity for the products that sell in it.
Frequently asked questions
When should I send Q4 inventory to Amazon?
As early as your capacity limits and Amazon's published holiday inbound dates allow, in several waves rather than one. Units that arrive after the peak rarely earn back their storage cost.
Are FBA storage fees higher in Q4?
Yes. Amazon's monthly storage fees are higher from October through December, so sending only what will sell during the season saves money.
Can you assemble holiday bundles before the season?
Yes. Gift sets and bundles can be kitted upstream, labeled as sets with their own FNSKU and held until the planned replenishment wave.
