1. What LTL Shipping Actually Is
LTL stands for less-than-truckload. Instead of paying for a full truck, you book space on a shared truck alongside other shippers' freight. Your inventory rides on a pallet, gets picked up at your location or prep center, and goes directly to an Amazon fulfillment center.
The other option most FBA sellers start with is small parcel delivery (SPD). You ship individual boxes via UPS, FedEx, or USPS. It works fine early on. But once you're sending 30, 50, or 100+ boxes per shipment, SPD gets expensive fast and the admin time stacks up.
Here's the thing about online arbitrage at scale: you're not drop shipping. You're buying inventory up front and sending it to Amazon before you make a single sale. Every dollar you spend moving boxes to an FC is a dollar not in your inventory budget.
"With online arbitrage you actually need to buy the inventory before you sell it. Especially with Amazon, you need to send the inventory to Amazon. Amazon stores your inventory and then whenever you have a sale they ship your inventory." Dropshipping vs. Online Arbitrage, Chris Mangunza, April 17, 2024
That inventory-first model is exactly why shipping costs are a real margin line item from day one, not an afterthought.
2. When Small Parcel Stops Making Sense
The rough break-even point for switching to LTL is around 150 pounds of freight per shipment. Below that, SPD usually wins on price and simplicity. Above it, LTL starts cutting your per-unit shipping cost by 40-60%.
Here's a real example. I was shipping 60 boxes to an FC, averaging 30 lbs each. That's 1,800 lbs of freight. My SPD cost was running about $0.45/lb. Switching to LTL on that same load brought it down to $0.19/lb. That's $468 saved on one shipment.
Running three of those shipments a week is $1,404 in weekly savings. That money goes back into inventory. That's how you actually scale without changing anything else in your operation.
The other signal to watch: if you're splitting shipments across 10+ UPS tracking numbers, you're spending time on SPD admin you could eliminate. LTL consolidates everything onto one or two pallets and one Bill of Lading. Much cleaner at volume.
3. Amazon's Two Shipment Methods in Seller Central
When you create a shipment in Seller Central, you choose between Small Parcel Delivery (SPD) or Less Than Truckload (LTL). Amazon also has a Full Truckload (FTL) option, but most sellers at the $10K-$100K/month revenue level use LTL. FTL only makes sense when you're filling an entire 48- or 53-foot trailer.
SPD: print box labels, drop them at a carrier location, done. LTL: print pallet labels, build pallets, schedule a freight carrier pickup, and the carrier hauls the pallets directly to the FC. More steps up front, but the per-pound cost drops significantly at volume.
One thing to confirm before you go down this path: not every Amazon FC accepts LTL deliveries. Seller Central will flag this during shipment creation, but double-check before you build your pallets. Getting rejected at receiving after four pallets are already wrapped is an expensive lesson.
4. Pallet Specs Amazon Will Actually Reject
Amazon is strict about pallet requirements. Get them wrong and the FC can refuse delivery outright. That means your inventory sits on a dock, you pay redelivery fees, and your restock timeline breaks.
Here's what Amazon requires:
- Pallet size: 40" x 48" GMA standard pallets only
- Max pallet height: 72" including the pallet itself (some FCs allow up to 98" with prior approval - call ahead and confirm in writing)
- Max pallet weight: 1,500 lbs per pallet
- Shrink wrap: fully wrapped on all four sides and over the top of the load
- Labels: one label on each of the four sides, placed between 15" and 45" from the floor
Use four-way entry pallets. Amazon forklifts need to enter from any direction. Two-way pallets get rejected at receiving, no exceptions.
Don't use broken or damaged pallets. If a board is cracked, throw the pallet out. Amazon receiving teams reject anything that looks structurally unstable, and you have no recourse once the carrier has already left your location.
5. How to Build an LTL Shipment in Seller Central
This whole process takes about 15 minutes once you've run through it a couple of times. Here's the step-by-step.
Step 1: Create your shipment in Seller Central as you normally would. Add SKUs, quantities, and any prep instructions.
Step 2: At the shipping method screen, select "Less Than Truckload (LTL)" instead of SPD.
Step 3: Enter your freight details: number of pallets and total weight. Be accurate here. Carriers reweigh at pickup and bill you for discrepancies.
Step 4: Print your pallet labels. Each pallet gets its own label set. Place one label on each of the four sides of every pallet.
Step 5: Book your carrier (covered in the next section). Enter the carrier's PRO number back into Seller Central once you have it confirmed.
Step 6: Mark the shipment as shipped in Seller Central on the day of pickup. Don't wait until the FC receives it.
That's the complete workflow. From there you wait for FC receive confirmation and your inventory goes live.
6. How to Find a Carrier and Book the Load
You have three main options for booking LTL freight: Amazon's partnered carrier program, direct with a carrier, or through a freight broker.
Amazon Partnered Carrier (APC): Amazon negotiates rates with carriers on your behalf. You book directly inside Seller Central. Rates are competitive for loads under 2,000 lbs. The carrier handles the FC delivery appointment automatically, which matters a lot (more on that in the mistakes section).
Direct with a carrier: Open a freight account with UPS Freight, Old Dominion, XPO, R+L Carriers, or Estes Express. Takes a few days to set up. Once you have accounts, you can pull quotes fast and often beat APC rates on heavier loads. Old Dominion and R+L are the most consistent for FBA shipments in my experience.
Freight broker: Services like Echo Global or Freightquote let you compare multiple carrier quotes at once. Good for large one-off shipments when you want to shop rates without opening direct accounts everywhere.
My recommendation: start with Amazon's partnered carrier. Once you're shipping LTL consistently, open direct accounts with two or three carriers and compare rates on each load. That extra 10 minutes of comparison usually saves $30-$80 per shipment.
7. What LTL Shipping Actually Costs
Freight pricing has a lot of variables: distance, freight class, weight, and accessorial charges. Here's what I actually pay.
Short haul (under 500 miles), 1,200 lbs, 2 pallets: $180-$220 total, around $0.15-$0.18/lb.
Long haul (1,000+ miles), 2,000 lbs, 3 pallets: $350-$450 total, around $0.18-$0.23/lb.
Compare that to UPS Ground SPD at $0.40-$0.55/lb on similar weights. The difference is real money at any meaningful volume.
Watch for these accessorial charges that get tacked on after the base quote:
- Liftgate service: $75-$150 if your pickup location doesn't have a loading dock (FCs have docks, so this only hits on the pickup side)
- Residential pickup: $100+ - avoid this by shipping from a prep center or commercial address
- Fuel surcharge: 15-30% on top of base rate, changes weekly
- Reweigh fee: charged when your actual pallet weight differs from what you booked
Get accessorial charges listed in writing before you commit. The base quote almost never includes everything, and surprises on the invoice kill your margin math.
8. Day-of Pickup: What to Expect
The carrier gives you a pickup window, usually four hours. Have your pallets staged, wrapped, and labeled before the window opens. Don't scramble when the driver shows up.
When the driver arrives, they hand you a Bill of Lading (BOL). Check it before you sign. Verify the number of pallets, total weight, and destination FC address. Sign only after confirming everything matches, then keep your copy.
The driver attaches a freight label to each pallet and loads them. Once they pull out, enter the PRO number into Seller Central and mark the shipment as shipped.
One thing I always do: photograph every pallet before it leaves. Front, sides, and top. Timestamped photos showing complete pallets have saved me from Amazon short-shipment chargebacks twice. Takes two minutes and the insurance value is massive.
9. LTL Mistakes That Cost Sellers Real Money
Most LTL problems come from skipping steps or making assumptions. Here are the five that actually hit sellers' margins.
Wrong freight class. Freight class (NMFC class) directly affects your rate. Most standard retail goods fall into class 50-100. If you misclassify, the carrier corrects it and bills you the difference after delivery. Use a freight class lookup tool or call the carrier before booking.
Inaccurate weight. Carriers reweigh at pickup. If your actual weight is higher than what you booked, you pay a weight correction surcharge on top of the rate increase. A $30 floor scale pays for itself on the first shipment.
Missing the FC delivery appointment. Amazon FCs require carriers to schedule a delivery appointment before showing up. If the carrier arrives without one, the FC can refuse the load. Amazon's partnered carrier handles this automatically. For direct bookings, confirm in writing that appointment scheduling is included in the service.
Forgetting the PRO number in Seller Central. You must enter the carrier's PRO number into Seller Central before Amazon processes the inbound shipment. Missing this step delays your receive date and pushes back your available inventory date.
Shipping to an FC that doesn't accept pallets. Not every FC takes LTL. Seller Central will flag it, but sellers still miss it. Confirm before you shrink-wrap four pallets.

When you're serious about scaling your Amazon FBA business, every dollar you save on shipping goes back into inventory. LTL is one of the fastest operational levers available to you without changing your sourcing model at all.
At $30,000/month in revenue, you might be shipping 200 boxes a week. SPD on those boxes runs $2,000-$3,000/month. Switching to LTL on eligible shipments cuts that by 40-60%. That's $800-$1,800 back in your pocket every month, compounding on every restock cycle.
"Scaling this business is easy. You just need to spend more money in inventory. That's it. You just need to spend more money in inventory to be able to scale your Amazon FBA business." You Will Never Scale Your Amazon FBA Business, Chris Mangunza, April 13, 2024
LTL gives you more money to put into inventory without touching your revenue numbers. Lower shipping cost per unit means more units bought per dollar, which means higher total revenue at the same margin percentage. That's the entire scaling mechanism and LTL is a direct input into it.
11. LTL vs. Using a Prep Center
If you're already using a prep center for your FBA business, you have a choice: ship LTL yourself or let the prep center handle freight consolidation.
Most prep centers offer their own LTL rates. They consolidate freight from multiple clients, which gets them better per-pallet pricing than most individual sellers can negotiate directly. The tradeoff is control. When you book LTL yourself, you control the timing, the carrier, and the paperwork.
My take: if your prep center's LTL rates are within 10% of what you'd get booking direct, let them handle it. Your time is worth more than the margin difference on smaller loads. If their rates are 25% higher, it's worth 30 minutes to book it yourself.
You can also pair LTL with an optimized Amazon FBA shipping plan to route inventory more efficiently. Fewer destination FCs per shipment means you hit the LTL weight threshold on more of your loads and get the rate break more often.
12. My Real Numbers After Switching to LTL
I started using LTL when I hit around $40,000/month in revenue. At that point I was sending 50-80 boxes per shipment to the same FC. SPD was costing me about $1.95/box on average.
Switching to LTL brought my per-box cost to $0.82. On a 70-box shipment, that's $57.40 in savings. On 3-4 shipments a week, that's $172-$230 weekly, or $750-$1,000/month back in my inventory budget.
I put every dollar back into products I'd already validated with sourcing software. The compounding effect on inventory capacity showed up within two restock cycles.
Inside The Scaling Society, we track shipping costs as a percentage of COGS. The target is under 8%. Most sellers doing SPD only are at 12-18%. Switching to LTL on eligible shipments is usually the single change that gets them under the threshold.
