Every Q4, the same split: sellers who reserved prep capacity and staged their inventory in waves, and sellers refreshing carrier tracking two days before Amazon's cutoff. ProShip3PL runs the first kind of season — capacity blocked against your forecast, holiday stock released from our Miami racks on a countdown built backward from the cutoff dates Amazon announces each year, gift sets assembled early, and a bench already booked for January's returns.
The seasonal trap isn't ignorance — every seller knows Q4 is coming. It's sequencing. Purchase orders get placed with holiday hopes, but warehouse capacity, assembly time and inbound timing get treated as details to sort out later. Later, in a prep warehouse, means the weeks when every seller in America wants the same bench hours at once.
The math is unforgiving in one direction only. Stock that reaches Amazon comfortably before the announced cutoffs sells through the entire event window. Stock that misses may still trickle in, but the season's biggest days won't wait for it. There is no November fix for a September planning gap — capacity sold out is sold out.
Our seasonal model splits the problem: your holiday buy lands on our Medley racks whenever your suppliers can deliver it — early is fine, storage is billed by space used — and enters FBA in planned waves. The first wave builds your base position, the main push beats the cutoffs with margin, and top-ups chase whichever SKUs the season decides to love.
Then the part everyone forgets: January. Holiday selling produces a returns wave, and sellers who planned for it turn returned units back into sellable inventory while others watch them pile up unfulfillable. Our removal-order bench gets booked for the wave before the season even peaks.
| Season phase | What should be happening |
|---|---|
| Late summer | Forecast shared, prep capacity reserved, gift-set recipes finalized |
| Early fall | Holiday buys arriving at our racks; base-load wave enters FBA |
| Cutoff window | Main push ships with days of margin against Amazon's announced dates |
| Peak weeks | Reactive top-ups on winners; FBM from our racks covers any FBA gaps |
| January | Removal orders land on a pre-booked returns bench; sellable units cycle back |
Your forecast becomes blocked hours on our schedule — so peak-week turnaround is a commitment to you, not a queue position.
Holiday stock racks here and enters FBA in planned waves — base load, main push, reactive top-ups — sized to sales, not to hope.
Seasonal multipacks built to your recipe, bagged or shrink-wrapped, labeled as single sellable units — scheduled weeks ahead of ship dates.
When Amazon publishes the year's inbound dates, your ship-by dates are computed backward from them — with buffer, in writing.
If FBA stock runs dry mid-surge, orders ship direct from our racks to buyers — the listing keeps selling while replenishment catches up.
Post-holiday removal orders inspected, graded, relabeled and cycled back into FBA — booked before the wave, not after it crests.
SKUs, volumes and arrival windows on paper; bench hours and rack space blocked against them.
Supplier freight arrives, gift sets get assembled, and the base-load wave enters FBA early.
The main push ships against the countdown from Amazon's announced dates — with margin, not luck.
Top-ups follow the winners through peak weeks; January's returns land on a bench that saw them coming.
Triple volume is a scheduling fact, not a crisis — if we know now. Reserve the capacity, and October's mountain becomes three planned waves instead of one desperate scramble.
Components arrive separately, leave as one giftable unit — assembled, wrapped and labeled here. Lock the recipe early: assembly time is the resource Q4 runs out of first.
That's a countdown failure, not bad luck. This year the ship-by dates get computed the day Amazon announces its windows — and your freight moves against a calendar, not a vibe.
Returns are the season's second act. Removal orders route here as the wave builds, units get graded and relabeled on arrival, and sellable stock is back in FBA while it still has a market.
Late summer — before your holiday purchase orders are even placed, ideally. Amazon announces its holiday inbound cutoff dates each year, and everything must count backward from them: FC receiving time, carrier transit, our prep bench, your supplier's production. Sellers who bring us their Q4 forecast in August or September get reserved capacity; sellers who call in mid-November are negotiating with physics.
Amazon publishes fresh cutoff dates each year — deadlines by which inventory must arrive at fulfillment centers to be reliably available for the big shopping events. We don't quote specific dates here because they change annually; the planning principle doesn't: treat the announced cutoff as your finish line, subtract Amazon's receiving time and carrier transit, and that's when freight must leave our dock. We build that countdown with you when the dates are published.
You share your Q4 forecast — SKUs, expected unit volumes, arrival windows — and we block bench hours and rack space against it. If your volumes shift, the reservation flexes; what it protects you from is arriving in the season's peak weeks as an unknown quantity competing for whatever capacity is left. There's no setup fee, so early planning costs you a conversation.
Instead of pushing your whole holiday buy into Amazon at once, the stock lands on our racks and enters FBA in planned waves — an early base load, a main push comfortably before the announced cutoffs, and reactive top-ups while inbound windows remain open. You stay in stock through the surge without parking months of peak-priced storage inside Amazon's network or gambling everything on one shipment's timing.
Yes — holiday multipacks and gift sets are a Q4 staple of our bench. Component products arrive from your suppliers, we assemble to your recipe, bag or shrink the set, and label it with its own FNSKU as a single sellable unit. The season-specific advice: schedule assembly weeks before your target ship date, because sets consume far more bench time per sellable unit than single-SKU prep.
The cutoff governs Amazon's receiving promise, not your ability to sell. Late stock can still ship into FBA and become available whenever it's processed — sometimes in time, without guarantees. The stronger fallback: inventory sitting at our warehouse can sell via FBM immediately, with orders shipping direct from our racks while the FBA units work through Amazon's queue. Missing the cutoff hurts; being out of stock everywhere hurts more.
Post-holiday returns arrive as removal orders to our dock, where each unit is inspected and graded: sellable units get fresh labels and re-enter FBA, units with damaged packaging get repackaged first, and units that shouldn't sell as new are segregated for your call — liquidate, hold or dispose. Booking returns processing before the season ends means January's wave lands on a bench that expected it.
Split it by certainty. Stock you're confident sells early belongs in FBA ahead of the rush. Stock whose demand is a guess belongs on our racks, releasing in waves as real sales data arrives — because pulling excess back out of Amazon mid-season is slow and costly, while pushing more in is fast. Peak-season storage pricing inside Amazon makes warehousing your whole bet there an expensive way to be wrong.
For sellers with reserved capacity, that's precisely what the reservation buys: your volumes are on the schedule and the clock holds. For walk-in volume in peak weeks, we quote turnaround honestly based on the queue at that moment rather than promising a number the calendar can't cash. It's the difference between a seat and standby — and the seat is free to book.
Send the form with your expected Q4 SKUs, rough unit volumes, when goods arrive from suppliers, and whether you'll need gift-set assembly or a staged release. Within one business day you get per-unit pricing, a capacity reservation, and a release calendar we'll anchor to Amazon's cutoff dates the moment they're announced for the year.
Share your Q4 forecast — SKUs, volumes, arrival timing, any gift sets — and within one business day you'll have per-unit pricing, reserved capacity, and a release calendar ready to anchor to the dates Amazon announces this year.
