Wholesale is a different job than arbitrage. An online arbitrage seller sends a prep center a stream of parcels. A wholesale seller sends a truck: twenty-six pallets on one bill of lading, 14,000 units across 40 SKUs, and a distributor packing list that may or may not match what is actually on the truck.
Wholesale sellers are the highest-ticket clients a prep center has. They are also the ones a sloppy operation hurts worst, because every error multiplies at pallet scale. One mislabeled SKU on your wholesale PO is 480 bad units under the wrong listing. Almost everything written about FBA prep assumes the parcel flow. This is the pallet flow, the way we run it in Miami, Florida for the wholesale side of the sellers we serve.
The 60-second version
The flow: PO at the distributor, LTL to the prep center, pallet receiving reconciled against the packing list, AQL sampling inspection, FNSKU labeling at scale, repack where needed, then outbound to Amazon by LTL or SPD.
The paper: three documents run the operation: the BOL, the packing list, and the distributor invoice. The invoice is also your ungating evidence, so it gets archived, not discarded.
The leverage: volume pricing is negotiable, typically 10 to 15 percent off published rates at 1,000 to 5,000 monthly units and more above that, but the discount is worth less than the written SLA that comes with it.
The expansion question: below roughly 15,000 to 20,000 units per month, one well-placed center plus smart shipment splits beats two half-managed relationships.
Step One: The PO Is Where Prep Problems Start
Most wholesale prep failures are decided before the truck leaves the distributor. Three free things need to happen at PO time.
First, get the packing list in advance, as a file, not a paper slip taped to pallet 14: SKUs, case quantities, units per case, expiration data if applicable. Receiving against a known manifest is twice as fast as receiving blind, and blind receiving is where shortage disputes go to die.
Second, get the case-pack specs: units per case, case dimensions, case weight. This determines whether the inventory can flow through Amazon case-packed or needs breaking and repacking, and that decision changes the prep quote materially.
Third, archive the invoice. It is your future ungating evidence, and it has formatting requirements covered below in the documents section.
The LTL Leg: Distributor to Prep Center
Wholesale volume moves inbound as LTL freight, and LTL runs on the bill of lading: shipper, consignee, pallet count, weight, freight class. Your prep center's dock is the consignee, with a scheduled delivery appointment, because LTL carriers deliver to schedules, not to hopes.
Tracking the inbound leg works the same way as the Amazon-bound direction we cover in how to track an FBA LTL shipment: the PRO number is the key, and the delivery appointment is the only date that matters.
Pallet Receiving: Conference Against the Packing List
Receiving wholesale freight is a counting problem before it is a prep problem. The sequence that works:
- Count pallets against the BOL at the dock, before signing.
- Break down each pallet and count cases against the packing list. Sealed cases, not units, at this stage.
- Open-case verification on a subset: if the packing list says 24 per case and the cases hold 20, a 17 percent shortage is hiding behind a correct case count.
- Photograph everything abnormal: crushed cases, broken seals, mixed-SKU pallets, retaped cartons. Timestamped photos are the difference between a credited claim and an argument.
- Report discrepancies inside 48 hours. Most distributors honor claims reported within 24 to 48 hours of delivery and reject nearly everything after. A prep center that receives Tuesday and reconciles Friday has quietly spent your claim window.
The output of receiving is a reconciliation report: what the packing list promised, what arrived, and the photo record of every gap. You should get it without asking. A prep center that cannot produce one is showing you one of the red flags worth taking seriously.
Sampling Inspection: AQL Without the Textbook
You cannot inspect 14,000 units one by one, and you do not need to. AQL sampling solves it. You inspect a fixed sample, count the defects, and accept or escalate the whole lot on that count. The full standard is ANSI/ASQ Z1.4. Here is the simplified version that covers wholesale prep, at general inspection level II and AQL 2.5:
| Lot size (units) | Sample size | Accept at | Escalate at |
|---|---|---|---|
| 281 to 500 | 50 | 3 defects or fewer | 4 or more |
| 501 to 1,200 | 80 | 5 defects or fewer | 6 or more |
| 1,201 to 3,200 | 125 | 7 defects or fewer | 8 or more |
| 3,201 to 10,000 | 200 | 10 defects or fewer | 11 or more |
| 10,001 to 35,000 | 315 | 14 or fewer | 15 or more |
A defect in FBA prep is practical: wrong UPC, damaged retail packaging, broken seals, missing expiration dates, units that do not match the ASIN's images. The sample gets pulled across pallets, not from one convenient carton, because distributor problems cluster by production run.
When a lot fails the sample, the decision goes back to the seller with photos: full inspection at an agreed rate, return to the distributor, or sell with eyes open. The prep center's job is to make the defect rate visible before Amazon's customers find it one review at a time.
Case-Pack vs Loose Units: The Fork in the Workflow
After inspection, the inventory takes one of two paths with very different economics.
| Factor | Case-packed | Loose or repacked |
|---|---|---|
| Amazon requirement | Identical units, same quantity per case, max 150 per case | Mixed SKUs allowed with box content info |
| FC receiving speed | Faster, one case label scanned per case | Slower, units received individually |
| Prep labor per unit | Lower, cases move as sealed blocks | Higher, every unit touched |
| Shipment split flexibility | Quantities move in case multiples | Full flexibility |
| When it wins | Stable catalog, case quantities align with the plan | Split destinations, partial quantities |
The expensive scenario is the middle one: the distributor ships cases of 36, Amazon's plan wants 250 units to one FC and 190 to another, and cases must be broken and repacked anyway. This is why case-pack specs belong in the PO conversation. Sometimes a different case quantity from the distributor saves more than any discount you will negotiate.
FNSKU at Scale, and When Repack Is Unavoidable
Most wholesale inventory is reseller inventory, so the manufacturer barcode is shared with every other seller on the listing and the safe play is FNSKU labeling: your Amazon-generated label on every unit, applied over the original UPC so an FC scanner can never read the wrong code.
At wholesale volume, labeling is an industrial process, not a sticker gun. Thermal-printed labels, never inkjet, because inkjet fades in a hot trailer. 100 percent coverage of the underlying UPC, no exceptions. Scan verification before the case is resealed. Doing this at thousands of units per day is what a dedicated FBA labeling service is built around.
Repack enters the workflow in three cases: master cartons damaged in freight, case quantities that do not divide into the shipment plan, and distributor cases that fail Amazon's box rules on weight or dimensions. An FBA inbound box must stay under 50 pounds unless it holds a single oversize unit, so a distributor's 62-pound case of canned goods gets repacked no matter how clean it looks.
Outbound: SPD or LTL Into Amazon
The outbound decision is volume math with a speed exception. As of 2026, Amazon's partnered carrier program prices both options aggressively, and the placement fee sits on top of either: roughly $0.14 to $1.90 per unit for standard-size items on minimal shipment splits, depending on tier and weight band, or $0 on Amazon-optimized splits to multiple FCs.
| Factor | SPD (small parcel) | LTL (pallets) |
|---|---|---|
| Sweet spot | Under roughly 2 pallets | 2+ pallets of stable catalog |
| Cost shape | Per box, rises linearly | Per pallet, wins at wholesale volume |
| Check-in speed | Usually faster, parcel receiving | Slower, dock appointments |
| Failure mode | Individual boxes straggle | One late appointment delays the load |
| Best wholesale use | Urgent replenishment near stockout | The main weekly replenishment wave |
Most wholesale operations run both: LTL as the default for the big waves, SPD as the relief valve when a fast mover is 10 days from stocking out. The full decision framework is in SPD vs LTL shipments, and what happens after delivery, which is where LTL loses days, is covered in how long Amazon check-in takes.
The Placement Fee, 2026 Schedule
The placement fee deserves its own line in the wholesale math because at pallet quantities it is real money. Amazon rebuilt the schedule on January 15, 2026, so any table published before that date is wrong now. Small standard runs two weight bands and large standard runs eight. The old large bulky tier was split in two: small bulky, which covers packages up to 37 by 28 by 20 inches, and large bulky above that. Rates are per unit, and Amazon-optimized splits are $0 in every tier.
| Size tier | Weight band | Minimal split | Partial split |
|---|---|---|---|
| Small standard | 8 oz or less | $0.14 to $0.32 | None |
| Small standard | 8+ oz to 16 oz | $0.16 to $0.32 | None |
| Large standard | 12 oz or less | $0.20 to $0.40 | None |
| Large standard | 12+ oz to 1.5 lb | $0.24 to $0.50 | None |
| Large standard | 1.5+ lb to 3 lb | $0.34 to $0.60 | None |
| Large standard | 3+ lb to 5 lb | $0.38 to $0.76 | None |
| Large standard | 5+ lb to 7 lb | $0.40 to $0.98 | None |
| Large standard | 7+ lb to 10 lb | $0.42 to $1.20 | None |
| Large standard | 10+ lb to 15 lb | $0.44 to $1.50 | None |
| Large standard | 15+ lb to 20 lb | $0.55 to $1.90 | None |
| Small bulky | 5 lb or less | $1.10 to $1.60 | $0.55 to $1.10 |
| Small bulky | 5+ to 12 lb | $1.75 to $2.40 | $0.65 to $1.75 |
| Small bulky | 12+ to 28 lb | $2.74 to $3.50 | $0.81 to $2.19 |
| Small bulky | 28+ to 42 lb | $3.95 to $4.95 | $1.05 to $2.83 |
| Small bulky | 42+ to 50 lb | $4.80 to $5.95 | $1.23 to $3.32 |
| Large bulky | 5 lb or less | $1.30 to $1.80 | $0.55 to $1.25 |
| Large bulky | 5+ to 12 lb | $2.10 to $2.90 | $0.65 to $1.80 |
| Large bulky | 12+ to 28 lb | $3.40 to $4.10 | $0.81 to $2.30 |
| Large bulky | 28+ to 42 lb | $4.70 to $5.60 | $1.05 to $2.95 |
| Large bulky | 42+ to 50 lb | $5.50 to $6.50 | $1.23 to $3.50 |
| Extra-large | Any weight | No fee | None |
Two structural rules matter as much as the cents. Partial splits exist only for bulky inventory, because Amazon removed the partial option for standard-size products on February 20, 2025, so a standard-size catalog chooses between minimal split and Amazon-optimized and nothing else. Extra-large products are exempt from the inbound placement fee entirely.
Then run the number on your own catalog. 5,000 units of a large standard item in the 12 ounce to 1.5 pound band, shipped on a minimal split at the top of that band, is 5,000 times $0.50, or $2,500 per wave, every wave. The same 5,000 units on an Amazon-optimized split is $0. Whether to pay it or split shipments is a per-catalog decision we walk through in how to avoid inbound placement fees.
The Paper That Matters
Three documents run a wholesale prep operation. The BOL is the contract of carriage and the receiving checklist; outbound to Amazon it carries the reference ID that gets the truck through the FC gate. The packing list is the reconciliation baseline: no packing list, no shortage claim, it is that direct. The invoice is the ungating asset: dated within 180 days, 10 or more units, distributor letterhead with verifiable contact details, and your business name and address exactly matching Seller Central.
Negotiating Volume Pricing
At wholesale volume, labor per unit drops: receiving is by the case, labeling runs in long batches, outbound builds full pallets. A prep center's cost curve bends downward with your volume, and your pricing should bend with it. The typical industry structure:
| Monthly volume | What to expect |
|---|---|
| Under 1,000 units | Published per-unit rates, no leverage yet |
| 1,000 to 5,000 units | 10 to 15 percent off published rates |
| 5,000 to 20,000 units | 15 to 25 percent off, plus negotiated receiving and storage terms |
| 20,000+ units | Custom contract pricing, committed capacity, dedicated dock windows |
Two notes from the other side of the table. Prep centers value predictability as much as volume: 4,000 units in a smooth weekly cadence earns a better rate than 6,000 in one chaotic end-of-month truck, so offer forecast visibility as part of the deal. And negotiate the whole stack, not just the headline per-unit fee: pallet receiving, monthly storage, repack, and shipment-build fees add up to more than the labeling line. Published baselines are on our pricing page, and the anatomy of the full stack is in prep service fees explained.
The SLA Wholesale Requires
At parcel volume, a slow prep center is an annoyance. At wholesale volume, it is a capital problem: a pallet sitting unprocessed is thousands of dollars earning nothing while sales velocity decays. The SLA is the contract term that protects the model.
- Dock-to-stock: freight received and reconciled within 48 hours of delivery, so the distributor claim window is never spent idle.
- Prep turnaround: 24 to 48 hours from work order to ready-to-ship, as a guarantee, not an average.
- Discrepancy reporting: shortage and damage reports with photos within 24 hours of receiving.
- Peak season protection: the turnaround number that applies in October and November, because a July average is worthless in Q4.
- A remedy: what happens when the SLA is missed. A guarantee without a consequence is a slogan.
PrepVia publishes its terms on the SLA guarantee page, which is the format to demand from any prep partner: numbers, in public, with a remedy attached.
When Two Prep Centers Make Sense
The east/west question comes up in every wholesale conversation eventually. Two centers are a scale tool, not a default. A second location splits your inventory into two pools that each need safety stock. It hands you two receiving relationships, two SLAs to police, and a routing decision on every PO before the distributor ships. That overhead only pays for itself when the freight savings are large and constant.
Geography still matters for the single-center case. A Miami location sits under an hour from both PortMiami and Port Everglades, inside the fast-growing southeastern FC cluster. That is the corner we chose, and the reasoning holds for any seller whose freight arrives on the eastern half of the country.
Frequently Asked Questions
How does a prep center receive wholesale pallets?
The truck delivers against a scheduled dock appointment and the receiving team counts pallets and checks for damage before signing the delivery receipt, because a clean signature closes most freight claims. The pallets are then broken down and every case is reconciled against the distributor packing list. Discrepancies are photographed and reported back within 24 to 48 hours, while distributor claim windows are still open.
What is AQL inspection in FBA prep?
AQL stands for Acceptable Quality Limit, a statistical sampling standard that inspects a fixed sample instead of every unit. For a lot of 1,000 units at the common AQL 2.5 setting, the inspector pulls 80 units and the lot passes if 5 or fewer defects are found. It gives wholesale sellers a documented quality gate at a small fraction of the cost of inspecting every unit.
Should wholesale sellers ship LTL or SPD to Amazon?
Ship LTL when the outbound load is two or more pallets of stable catalog inventory, because per-unit freight cost is far lower at that volume. Use SPD when speed matters more than freight cost, such as replenishing a SKU that is close to stocking out, since small parcel shipments usually check in faster at Amazon. Most wholesale operations end up running both depending on the week.
What volume discounts do prep centers offer?
Typical structures run 10 to 15 percent off published pricing at 1,000 to 5,000 monthly units and 15 to 25 percent above 5,000 units, with custom contracts past 20,000. Below about 1,000 units per month, published rates apply. The discount is only half the negotiation, the other half is a written SLA for receiving and turnaround at that volume.
How much is the Amazon inbound placement fee in 2026?
It depends on size tier and weight. On a minimal split, standard-size units run from $0.14 to $1.90 each, small bulky units from $1.10 to $5.95, and large bulky units from $1.30 to $6.50. Amazon rebuilt the schedule on January 15, 2026 and split the old large bulky tier in two, adding small bulky for packages up to 37 by 28 by 20 inches. Extra-large products pay no placement fee, and any Amazon-optimized split across five or more destinations is $0.
Final Take
Wholesale prep is not harder than parcel prep, it is less forgiving. The workflow is a chain of small disciplines: the packing list before the truck, the count before the signature, the sample before the labels, the invoice in the archive, the SLA in writing. Each takes minutes. Skipping any one costs pallet-scale money, weeks later, in a form that is hard to trace back. Pick a prep partner who already runs the chain, put the pricing and the SLA on paper, and the pallet flow becomes what it should be: boring, repeatable, and cheap per unit.
