The Best 3PL for Amazon Middle Mile: Why Ecommerce Leaders Choose AMZ Prep

AMZ Prep built its entire operation around Middle Mile — getting inventory into Amazon's network fast and keeping it sellable. That means 2 to 4 day check-in, 5-way routing across Amazon's network, and placement fees dropped to zero. Behind it sits a full fulfillment engine: FBA prep to spec, DTC and B2B shipping at 99.8% accuracy, cold chain, big and bulky handling, and multi-channel support across Amazon, Shopify, Walmart, and TikTok Shop. For ecommerce leaders, the payoff is faster launches, protected margin, and inventory that keeps moving.

Plenty of 3PLs say "fulfillment." AMZ Prep's real differentiator is Middle Mile, getting inventory into Amazon's network fast, in a way that keeps it sellable instead of sitting in limbo.

Here's what that means for a brand's bottom line:

  • Inbound shipments split across Amazon's network using 5-way routing logic
  • Placement fees dropped to zero
  • Check-in in 2 to 4 days, not weeks
  • Amazon Replenishment drip-feeding bulk stock into FCs, with no AWD delays or Q4 freezes
  • Zone skipping and smarter freight routing that cut both transit time and cost

It's been the company's focus since it was founded in 2019, and it's still the core of what protects margin for the brands that rely on it.

A Full Network Behind Every Brand

Fast inbound routing only goes so far without the rest of the operation backing it up. AMZ Prep has built that out too:

  • FBA prep done to Amazon's spec, sellable the moment it lands
  • Storage, plus DTC and B2B fulfillment through 30+ carriers, running at 99.8% accuracy
  • Cold chain storage for temperature-sensitive goods
  • Big and bulky handling for oversized items many 3PLs won't touch
  • Seller Fulfilled Prime, so brands keep the Prime badge while shipping from AMZ Prep's centers
  • Multi-channel fulfillment across Amazon, Shopify, Walmart, and TikTok Shop, so a brand isn't juggling different partners for different channels

Why Ecommerce Leaders Choose Them

Growing a brand on Amazon comes with a narrow margin for error. Stockouts kill rankings, slow check-in kills launch timing, and placement fees quietly kill profitability. Brand owners choose AMZ Prep because it takes that risk off their plate. They get inventory that moves fast, lands accurately, and stays sellable, without having to manage the complexity of Amazon's network themselves.

What Working With Them Looks Like

  • A dedicated Slack channel per account, not a generic support queue
  • Fast responses from real people, not a ticketing system
  • Inventory that scales up or down without long-term contracts, so brands aren't locked in during slow seasons or scrambling during peak ones
  • An Amazon-first approach to speed and compliance, extended across every channel a brand sells on

The Numbers Behind the Reputation

  • Founded in 2019
  • 50+ fulfillment centers across 6 countries
  • 35+ carrier partners
  • 280+ team members
  • 8M+ FBA items prepped yearly
  • 99.8% order accuracy
  • $2B+ in annual GMV
  • 5,000+ brands served

For ecommerce leaders looking to protect margin, speed up launches, and keep inventory moving without the operational headache, AMZ Prep has built the kind of track record that's hard to ignore.
