Q4 Amazon Freight: Why to Switch Your Logistics Partner during Peak
Switching freight in Q4 feels risky. Waiting is riskier. Why peak season is the best time to test a new Amazon inbound lane, and how to run the test this week.
Q4 is prime time for Amazon sellers (pun intended), which means everyone is focused on growth and no one wants to make any big logistics moves.
But sometimes, it’s riskier to stick with a slow solution rather than try new freight solutions…especially if it means getting inventory into Amazon faster during peak.
Ask: If you could send every FBA shipment into Amazon as a floor-loaded FTL, would you?
If that question means something to you, you already know the answer. And you already know why January is the wrong time to act on it.
If your tendency is to make big moves in January to prevent Q4 disruptions, we’ve got a few compelling reasons to rethink your strategy.
The best time to change how your inventory gets into Amazon could well be in the midst of peak season. Let’s look at how to decide whether or not that’s a fit for you.
Your Q4 goal should be to stay checked-in
Amazon has already set up their holiday inventory arrival cutoffs, and if you’re trying to make BFCM, they’re all in October.
- October 14 for AWD shipments
- October 21 for FBA shipments using minimal shipment splits
- October 28 for FBA shipments using Amazon-optimized shipment splits
It’s easy to say “we sent our inventory in on time, so we’ll be okay.” But BFCM is just one weekend of the biggest selling quarter of the year. If you sell out in November you’ll need to replenish and ensure your inventory is checked-in and sellable through December. And December is when the Amazon inbound network hits heavy congestion.
We’ve watched this issue play out for a lot of brands who suddenly find themselves sending inventory to Amazon in Q4 with the acceptance that they aren’t going to get checked in until January. That’s all inventory that’s paid for, taking up your cash flow, and hogging your inventory allocation.
But it doesn’t have to be that way as long as you plan accordingly.
Two different clocks to track during peak
When you ship into Amazon, you need to keep your eye on two timelines.
Clock one: arrival to check-in. Your freight arrives at an Amazon facility and waits to be received. Once units are checked in, they are sellable.
Clock two: check-in to Prime eligibility. A shipment sent to a single destination typically lands at a national inbound cross-dock. Amazon re-sorts it and splits it out to regional inbound cross-docks, then on to fulfillment centers. Units become Prime-eligible only once they reach a localized fulfillment center.
Amazon runs clock two. Nobody outside Amazon can promise you a time-to-Prime number.
But what you do control is the inbound decision that launches the whole process. How does your freight arrive? Where is it sent? Does it show up as the kind of load Amazon’s network receives fastest?
In our experience, standard check-in times range anywhere from 7 to 43 days, depending on shipment type, destination, and season. But for ZonPrep, we guarantee a year-round check-in time of 5 days. We regularly beat this during the rest of the year, but in Q4 that’s where our guarantee really makes a difference.
How we achieve a 5-day check-in SLA
If you asked an Amazon logistics operator to design the ideal inbound shipment, it would look like this:
- A full truckload, floor-loaded. Amazon’s regional facilities are built for automated, conveyor-based receiving, and they’re set up to prefer floor-loaded trucks.
- Sent direct to a regional facility. Optimized splits go to Amazon’s regional locations instead of a single national destination. That’s how you avoid inbound placement fees, and it’s the shipment type Amazon gives the latest holiday cutoff.
- With a live unload appointment. The truck arrives on a scheduled appointment and gets unloaded on arrival. As Lou puts it, a live unload “forces receiving.”
That combination is as good as inbound gets. It’s what Amazon’s own system rewards, and it’s the lane that holds up best when the network is under peak load.
However, very few brands have the volume to send inventory to Amazon in this way. Amazon-optimized splits mean shipping to several regional destinations, while filling a floor-loaded FTL to each of them, every replenishment cycle.
Because you need massive volume and coordination with Amazon to achieve this, many brands compromise in one of two ways:
- Optimized splits via LTL or small parcel. No placement fee, but more carriers, more appointments, more variance, and more days of each shipment sitting in a receiving queue.
- Minimal splits. Fewer shipments to manage, but you pay the inbound placement fee, give up a week of holiday runway (October 21 instead of October 28 this year), and your units take the long road through Amazon’s transfer network.
Consolidate to leverage economies of scale in Q4
Consolidation is the name of the game in Q4. It helps you optimize and get your inventory checked-in at Amazon much faster than the industry average.
When you work with ZonPrep, this is how your inventory would flow through our cross-dock facilities.
- Your Amazon-bound freight comes into our facilities in McDonough, Georgia, and gets combined with Amazon-bound freight from other brands.
- It leaves as floor-loaded FTLs to Amazon’s regional cross-docks.
- Our shipments have set lanes thanks to full trucks and massive volume.
The operational detail behind that:
- 50 to 70 inbound trucks a day received at our facilities, consolidated into 30+ floor-loaded FTLs leaving for Amazon regional cross-docks Monday through Friday
- Live unload appointments booked 21 days in advance
- Listed as a carrier in Amazon Carrier Central, the only Amazon-focused supply chain partner that is
- McDonough sits within one-day ground of roughly 80% of the US population
All of that comes together to get you:
- An average of 24 to 48 hours to check-in at Amazon, measured from when shipments leave our facility.
- A 5-day SLA from arrival at our facility to arrival at Amazon. That includes Prime Big Deal Days, Black Friday, Cyber Monday, and the rest of Q4 peak.
Compare that with the 7-to-43-day range that the rest of the industry has come to expect and accept. You can optimize your Q4 inbounds to make the difference between December replenishment ready to sell in December, or December replenishment that has to wait until the new year.
We’ve done the work of building the network so you don’t have to fill five trucks a week on your own.
Why switching freight during Q4 is less scary than it sounds
The “don’t touch anything in Q4” instinct assumes switching is a big operational lift. For freight, it isn’t.
What stays the same:
- You still create your shipments in Seller Central.
- Your prep stays where it is and runs the way it runs today.
- Your SKUs, labels, and cartons don’t change.
- It’s all inventory that was already headed to Amazon.
What changes: where your freight goes after it leaves your warehouse or prep partner, and what happens once it gets to Amazon. It gets checked in, and it’s sellable.
Let’s be straight about the line we’re drawing. Moving your entire prep operation in the middle of peak is a different decision. It takes planning, and brands that do it in Q4 have usually scheduled the move well in advance. We wouldn’t push anyone to rip out a working prep setup in October.
Freight is different. You can route a single shipment through consolidation, watch the check-in data, and decide from there. There are no contracts or prepayments. Your first shipment is a trial, and we earn the relationship from there.
Why Q4 is the best time to test a new lane
Q4 is actually an ideal test window, since you have high volumes to test new partners and it’s the time of massive opportunity.
Your volume is at its peak. A lane switch in a slow month gives you a handful of shipments to judge. In Q4 you’ll see dozens in a few weeks, under the hardest conditions the network sees all year. If a lane holds up in December, it’ll hold the rest of the year.
You probably aren’t locked in. Supply chain isn’t like an agency retainer. Most of the brands we speak with aren’t tied to contracts on their freight, so they have the freedom to make the call that serves their quarter.
The stakes are highest. A slow check-in in February costs you a few days of availability. A slow check-in in December costs, for some sellers, the bulk of their annual revenue.
January tests nothing. Switch after the holidays and your new lane won’t face real pressure until Prime Day. You’ll spend six months not knowing if it works.
Why waiting is the riskier bet
Q4 makes slow inbound processes more expensive in ways that compound.
Storage gets pricier while you wait. Amazon’s monthly inventory storage rates step up for October through December, sometimes as much as 3x depending on category. Slow transfer pushes sellers to carry more weeks of cover inside Amazon, and Q4 is exactly when that buffer costs the most.
Minimal splits cost you a week of holiday runway. This year that’s the difference between an October 21 and an October 28 arrival cutoff, on top of the placement fee itself.
Late-quarter replenishment is the inventory most at risk. Shipments that land before the holiday cutoffs have the most runway. December replenishment has the least, and it arrives when the network is at its busiest.
None of this is Amazon punishing anyone. Placement fees and transfer time are how Amazon’s network handles freight that arrives in a form it has to re-sort. Send freight the way the network is built to receive it, and it moves faster. That isn’t a workaround. It’s using Amazon’s own system the way it was designed.
What to do this week
You don’t need a strategy offsite to test this. You need four things:
- Pull your last 90 days of inbound. For every FBA shipment, measure shipment creation to check-in. Look at the spread, not the average. Your slowest shipments are the best preview you have of December.
- Count your floor-loaded FTLs. How many of those shipments went direct to a regional facility as a full, floor-loaded truck with a live unload? For most brands, the honest number is close to zero.
- Map your remaining Q4 replenishment. List every ship date from now through December. Mark the ones that will land after mid-November. Those are the shipments your current lane has to protect.
- Run the numbers on your account. Our free ZonPrep Shipments Tool for Chrome pulls your shipment history from Seller Central. It shows the inbound placement fees you’re paying, your partner carrier costs, and your true per-pallet rate.
Now, if you could send every FBA shipment as a floor-loaded FTL, would you?
If the answer is yes, there’s no reason to wait until January to start. Talk to our team about Cross-Dock and put one Q4 shipment through the lane.
Let’s get after it.
