Middle mile logistics is the freight leg between a port, factory, or origin warehouse and a fulfillment center. For Amazon sellers, that means the trip from a prep center or 3PL into the FBA network. Whoever runs this leg has a big say in check-in speed, inbound fees, and how often a listing stays in stock.
Plenty of brands pick a middle mile partner as an afterthought to warehousing. The ones with steady inbound performance usually treat it as a separate decision. This guide looks at the main middle mile logistics providers, how they differ, and what to measure before choosing one.
Where the Middle Mile Starts and Stops
When sellers search what is middle mile logistics, they’re usually trying to place it in the wider supply chain. Most supply chains have three legs.
- First mile: Goods travel from the factory to a port or origin warehouse.
- Middle mile: Goods travel from that origin point to a distribution or fulfillment center.
- Last mile: Orders travel from the fulfillment center to the customer.
Amazon handles the last mile for FBA sellers. So the middle mile is the final stretch a seller actually controls.
A side-by-side comparison of middle mile logistics companies shows how providers differ by lane, speed, and service model. Before comparing anyone, a free middle mile audit tool helps sellers benchmark what they pay and how long check-ins take today. With both in hand, partner conversations get much more specific.
Freight in this leg moves in a few common ways. Full truckload (FTL) fits a large, steady volume. Less than truckload (LTL) fits pallet loads that share a trailer. Small parcel delivery (SPD) fits case-level shipments. Consolidated programs pool freight from several brands onto shared trucks.
Why Amazon Sellers Watch This Leg Closely
Amazon’s inbound rules tie the middle mile directly to margin. Three pieces matter most.
Inbound Placement Fees
Amazon charges an inbound placement fee when sellers ship to fewer destinations. Accepting Amazon’s full split of destinations can lower or remove that fee. The trade-off is routing. Split shipments only make sense with a partner who can send cases to several fulfillment centers without extra cost.
Check-In Time
Delivery isn’t the finish line. Inventory still has to be received and made available for sale. Carriers who deliver to Amazon every day tend to know its appointment and receiving rules well, and that shows up as more predictable check-ins.
Capacity Limits
Amazon sets capacity limits on FBA storage. Smaller, more frequent shipments help sellers stay inside those limits while keeping stock turning.

Amazon-Focused Middle Mile Providers
These middle mile companies for Amazon build their service around FBA inbound.
Amazon Freight moves truckload and LTL freight through Amazon’s own network. It suits brands that already handle prep and labeling and mainly need transport.
AMZ Prep combines FBA prep, storage, shipment consolidation, and transport into Amazon in one workflow. It fits brands selling on Amazon alongside DTC, retail, or wholesale.
Pattern works with larger brands on Amazon marketplace operations, including inventory movement into fulfillment centers. It fits companies where Amazon is the main sales channel.
ZonPrep focuses on FBA prep and inbound handling. It fits sellers who need inventory labeled, packed, and ready for Amazon receiving at volume.
Freight Networks and Brokers
These middle mile transportation companies provide capacity rather than prep or storage. They work best for brands that run their own warehouse or already have a prep partner.
C.H. Robinson is one of the largest freight brokers, with global coverage and carrier coordination. RXO offers truckload brokerage and managed transportation across a wide carrier network. J.B. Hunt runs truckload, dedicated, and intermodal services for national lanes. XPO concentrates on less-than-truckload freight, which suits regular pallet shipments.
Retail and Enterprise Specialists
RJW Logistics Group is built around consumer packaged goods and retail replenishment, including store and distribution center delivery. Hub Group supports enterprise supply chains with intermodal and managed transportation.
Cold Chain
Lineage specializes in temperature-controlled storage and transport. Food, beverage, and other temperature-sensitive brands usually need a specialist like this for at least part of the middle mile.
How to Evaluate Middle Mile Logistics Partners
The best middle mile logistics companies for one brand can be a poor match for another. Lane coverage, SKU profile, and channel mix all shift the answer. These are the areas where middle mile logistics partners tend to differ most.
Amazon Inbound Experience
Middle mile providers for Amazon FBA should know Amazon’s labeling, pallet, and appointment rules without being coached. Ask for their typical time from pickup to receiving complete. Lane-level numbers are more useful than a network-wide average.
Split Routing
A good partner can take one inbound plan and route it to several fulfillment centers without re-handling the freight. That’s what makes Amazon’s lower-fee placement options workable week to week.
Consolidation and Shipping Frequency
Most brands don’t fill a full truck every week. Consolidated programs combine loads from several sellers on one trailer. That means a brand with six pallets can ship weekly instead of waiting a month to fill a truck. Regular, smaller shipments also keep FBA storage levels steady across the month.
Tracking From Pickup to Receiving
Some providers stop tracking once the truck leaves the dock. The more useful ones show status all the way to Amazon’s receiving scan. Case-level detail matters here. It tells planners which SKUs are live and which are still on the road.
How Freight Gets Priced
Providers usually price by the pallet, by the cubic foot, or at a flat rate per lane. Each model fits a different shipment profile. Per-cubic-foot pricing suits partial pallets and mixed case loads. Per-pallet pricing tends to favor dense, full pallets. Check how extras like liftgate service or driver detention appear on the invoice, since these can shift landed cost month to month.
Communication
Freight rarely runs exactly to plan. When it doesn’t, a named contact who answers quickly is worth more than a slightly lower rate.
Start With a Middle Mile Audit
It’s hard to judge a new partner without knowing where things stand today. A middle mile audit gives you that baseline. It shows what each shipment really costs and how long it takes to become sellable.
A useful audit covers the last 90 days and tracks:
- Average transit days by lane
- Days from delivery to receiving complete
- Inbound placement fees paid per unit
- Total landed cost per unit at FBA
- Shipments and destinations per inbound plan
- Freight mode mix across FTL, LTL, and SPD
- Stockout days tied to inbound timing
Pulling this together by hand gets slow across a large catalog. A middle mile audit tool for Amazon FBA puts freight cost and check-in speed side by side, which makes the gaps easy to spot.
Whether you use an Amazon middle mile audit tool or a spreadsheet, run it on a set schedule. Quarterly reviews catch lane changes, fee updates, and seasonal shifts before they add up.
Brands Selling Beyond Amazon
Many brands now sell on Amazon, their own site, Walmart, and wholesale accounts at the same time. Middle mile logistics companies for ecommerce should be able to serve that full mix from one inventory pool.
In practice, that means holding stock in a regional warehouse and sending it wherever demand shows up. Amazon gets steady replenishment. DTC orders ship from the same inventory. Retail orders follow each buyer’s routing guide.
If wholesale or retail is part of the plan, confirm the partner handles EDI and retailer labeling rules. It saves bringing on a second vendor later.
What to Confirm Before Signing
A short checklist keeps partner calls on track. Get each of these in writing.
- Lane-level transit times for your main origin points
- Average Amazon check-in time over the last quarter
- Support for Amazon’s multi-destination split shipments
- Pricing model and the full list of accessorial fees
- Tracking access for your planning team
- A named account contact and response time commitments
- Peak season capacity plans and cutoff dates
Building a Middle Mile That Scales
The right partner can grow with the catalog and the channel mix. Brands that measure first, compare second, and review on a schedule usually see the steadiest inbound results. A clear baseline now makes every later freight decision easier.
Frequently Asked Questions
What is middle mile logistics?
Middle mile logistics moves inventory from a port, factory, or origin warehouse to a fulfillment center. For Amazon sellers, it covers the freight leg from a prep center or 3PL into FBA. It’s the last leg sellers control.
What types of middle mile logistics companies are there?
The main types are inbound-focused 3PLs, freight brokers, asset-based carriers, retail consolidators, and cold chain specialists. Amazon sellers usually compare 3PLs with built-in freight against brokers paired with a separate prep partner.
How do middle mile providers for Amazon FBA help reduce placement fees?
They route one inbound plan to several Amazon fulfillment centers. Amazon charges lower or no placement fees when sellers accept more destinations. Consolidated freight makes multi-destination shipping affordable for brands of most sizes.
What should a middle mile audit include?
A middle mile audit tracks transit days by lane, check-in time, placement fees per unit, and landed cost. It should also flag stockout days linked to inbound timing. Ninety days of data gives a reliable baseline.
How often should Amazon sellers run a middle mile audit?
Once a quarter is enough for most brands. It’s also worth running one before Q4 or after Amazon updates its inbound fees. A fresh audit helps before signing with a new freight partner too.
How are middle mile transportation companies different from last mile carriers?
The difference is what they carry and where it goes. Middle mile carriers haul pallets and cases between warehouses. Last mile carriers bring single orders to a customer’s door. Amazon covers that final step for FBA sellers.
How do sellers choose between middle mile logistics companies?
Start with your own audit numbers, then see which provider improves them. Lane coverage, Amazon check-in times, and split routing usually show the biggest differences. Shipment volume and SKU mix narrow the list further.
