Amazon prefers inbound shipments sent to regional locations for faster geographical distribution. Doing this eliminates the inbound placement fee, speeds up time-to-Prime eligibility, and lowers the amount of on-hand inventory you carry in FBA storage.
When you ship to a single location, Amazon does the distribution work for you, and charges you for every step of that journey. Here's exactly what happens to your inventory after it leaves your warehouse, and where the fee kicks in.
You create your FBA shipments sending to one location. Amazon assigns a single destination, typically a National Inbound Cross-dock (IXD), and you ship everything there.
Amazon receives and sorts your bulk shipment. This is the moment the FC transfer process begins, and where your placement fee is triggered. From here, Amazon splits your one large shipment into five regional shipments.
Amazon redistributes your inventory across five regional cross-dock centers to position stock closer to customer demand. Your units are in transit, not sellable, throughout this process.
Only once your units reach the final fulfillment center are they Prime-eligible. The longer that transfer takes, the longer your inventory sits unsellable, and the more carrying costs you absorb.
Send your inventory to ZonPrep. We do the distribution work, going directly to Amazon's Regional IXDs. We are listed as a carrier in Amazon Carrier Central, giving our trucks live unload appointments that substantially decrease check-in time.
Send all your inventory to ZonPrep instead of Amazon. We receive 50–70 inbound trucks daily and ship 30+ floor-loaded FTLs to Amazon's Regional FCs every day.
We consolidate your shipments with other sellers going to the same Regional FC, creating full truckloads that Amazon's algorithm treats as optimized, placement-fee-free inbounds.
Your inventory arrives directly at the Regional IXD, bypassing the National IXD and the FC transfer process that triggers the fee. Amazon receives your units already distributed.
Units move directly to the FC and become Prime-eligible, faster than via a National IXD, with no placement fee charged and no weeks of FC transfer time eating into your days-on-hand.
This isn't a workaround. It's how you use Amazon's own system correctly, with the right hub location, the right routing logic, the right inbound configuration, and the ability to send every load as a floor-loaded FTL.
When you optimize shipment splits, you'll generally get splits going to three or four facilities on the East Coast and only one on the West Coast. ZonPrep's McDonough, GA location sits within one-day ground of 80% of the U.S. population, so Amazon's algorithm routes your inventory to nearby FCs at zero placement fees.
We receive 50–70 inbound trucks to our McDonough facility daily, consolidated into 30+ floor-loaded FTLs leaving to Amazon regional XDs Monday through Friday. At these XDs we secure live unload appointments booked 21 days in advance, ensuring 24–48 hour inbounds at Amazon once they leave our facility.
Amazon's regional facilities are set up for automated receiving, they prefer floor-loaded trucks so they can bring conveyor belts directly to the truck and start receiving. Palletized loads to regionals actually slow down inbound times. This is why we floor-load all of our trucks.
Per-unit prep pricing shows you one of the three numbers that make up your inbound cost. Placement fees and freight sit on separate invoices, so they never enter the comparison. Blend all three into a single per-pallet figure and the real cost of your inbound strategy shows up in one line.
Run it on your last six months tonight. When the number lands higher than the per-unit conversation suggested, the gap is in placement fees and fragmented freight, not prep.
Spoiler: none of them have to do with ad spend. These are the levers you control on your own inbound, whether you operate it yourself or hand it to a partner.
The volume changes with the season. The rhythm doesn't. A fixed weekly cadence is what lets every downstream lever work: lanes stay priced, trucks stay full, and Amazon sees a predictable inbound pattern instead of bursts.
One origin. One destination. Every week. A single repeated lane is the only way to hold a rate, and it turns freight from a quote-by-quote scramble into a fixed input. Benchmark it quarterly so the rate stays honest.
Trade scattered LTL for floor-loaded FTL and larger replenishment volumes. One truck at a flat per-pallet rate beats a handful of partial loads on every measure that matters: cost, damage, and how fast Amazon receives you.
The day your freight lands at the prep facility decides which week it reaches Amazon. Arrive Monday and you are into Amazon's network that same week. Arrive Wednesday or later and it rolls to the next one, costing you a full week of cover.
The rule: 5 or more boxes per SKU and Amazon's split options open up. Splitting beats paying the placement fee every time. Your freight lands closer to demand on day one, checks in faster, and the fee stops scaling with every unit you ship.
Every shipment: collect the proof of delivery, know your claim window, assign an owner. A signed POD is what turns a discrepancy between units shipped and units received into units recovered instead of units written off.
Amazon's inbound placement fee structure changed significantly in 2024. Sellers who haven't re-evaluated their inbound strategy are likely paying more per unit than they realize, because the fee appears on invoices as a small per-unit line item, not as the six-figure annual expense it actually is at scale.
The calculation is straightforward: take your monthly unit volume, multiply by your average placement fee per unit, multiply by 12. For most sellers doing 50,000+ units/month, the number is uncomfortable.
