Fee Intelligence: Why Every Amazon Fee Is Intentional
On Shopify, you set the rules for how your business runs. On Amazon, you’re playing by Amazon’s rules, and every fee exists to keep you playing by them. That’s the reality Fee Intelligence is built to map.
That’s not a complaint. It’s the actual design of the platform, and Amazon has said so, in its own words, since before third-party sellers ever existed on it. This post introduces Fee Intelligence, a project built to understand every fee and program that Amazon has instituted against that design. It’s not just about what the fee costs. It’s about understanding what the fee is incentivizing, or what the fee is trying to course-correct.

What Jeff Bezos Actually Said
Jeff Bezos published a letter to Amazon’s shareholders every year he served as CEO, and those letters lay out what Amazon was built to do. Well before third-party sellers existed on the platform, Amazon had a clear goal in mind.
In the 1998 letter, Bezos wrote:
“We intend to build the world’s most customer-centric company.” — Jeff Bezos, 1998 Amazon Shareholder Letter
In the same letter, he explained what that meant in practice:
“I constantly remind our employees to be afraid, to wake up every morning terrified. Not of our competition, but of our customers.” — Jeff Bezos, 1998 Amazon Shareholder Letter
This wasn’t just a marketing pitch. It was an operating philosophy from the very beginning.
That philosophy was the foundation on which the third-party marketplace was built. In 2000, Amazon invited outside sellers to compete directly on its own product pages, a decision Bezos later admitted was, at the time, internally controversial. Amazon’s own team worried it would cannibalize Amazon’s retail business, and that Amazon could get stuck holding excess inventory if a listing went to a third-party seller instead. Bezos explained the reasoning anyway, in the 2005 letter:
“If a third party could offer a better price or better availability on a particular item, then we wanted our customer to get easy access to that offer.” — Jeff Bezos, 2005 Amazon Shareholder Letter
Sellers weren’t gaining an online platform that was meant for them to explore entrepreneurship. They were invited to compete with Amazon as long as the level of service was better than what Amazon itself was offering. The goals and philosophy of Amazon didn’t change; only who was able to join them, a history covered in more depth in Amazon Built for Buyers, Not Sellers.
Did that logic actually hold up over the next two decades, or was it early rhetoric that faded once the marketplace got large? The numbers answer that directly.
The Growth That Hasn’t Stopped
In the 2018 letter, Jeff Bezos published a year-by-year breakdown of third-party sales as a share of everything sold on the platform:
“1999: 3% … 2001: 6% … 2005: 28% … 2010: 34% … 2014: 49% … 2017: 56% … 2018: 58%. The percentages represent the share of physical gross merchandise sales sold on Amazon by independent third-party sellers, mostly small- and medium-sized businesses, as opposed to Amazon retail’s own first-party sales. Third-party sales have grown from 3% of the total to 58%. To put it bluntly: Third-party sellers are kicking our first-party butt. Badly.” — Jeff Bezos, 2018 Amazon Shareholder Letter
Part of what kept this percentage climbing was Fulfillment by Amazon (FBA). In 2014, Jeff Bezos described the mechanism directly:
“FBA completes the circle: Marketplace pumps energy into Prime, and Prime pumps energy into Marketplace.” — Jeff Bezos, 2014 Amazon Shareholder Letter
The more sellers used FBA, the more Prime-eligible selection Amazon had to offer. More selection made Prime membership more valuable, which brought in more customers, which made FBA more attractive to the next seller. The infrastructure under FBA was not just built for sellers. It was built for Amazon to receive, store, and fulfill as well as possible. What Amazon believed was best, most efficient, and most conducive to running a retail operation, it extended to FBA sellers.
The trends haven’t reversed. Amazon’s total sales have kept hitting new records every year: $575 billion in 2023, $638 billion in 2024, and $717 billion in 2025. Sellers have kept pace with it, now accounting for roughly 61% of everything sold on the platform. As Amazon continues to grow in overall sales, third-party sellers aren’t getting squeezed out. They’re actually taking a larger percentage of the pie.
So if fees and programs run on this same logic, the real question is how to actually read a specific one that way.
Fee Intelligence
If sellers are a mechanism aiding in and serving to further Amazon’s own goals, then every fee that Amazon charges and each program it has built is essentially a move towards that pursuit, and not randomly done. Fees and programs also aren’t purely there to make money off of sellers. That’s the idea behind Fee Intelligence, a project to analyze what each fee and program is optimizing for, not just what they cost.
Understanding a fee requires two perspectives. The first: how has Amazon described itself and its goals until now? Based on Amazon’s customer obsession, how does everything fit into serving the customer better?
The second is not as easy to understand, but no less important. Every business runs into limits of some kind eventually. A warehouse can only store so much. A shipping dock can only receive so much in a day. Those operational limits, or constraints, wherever they show up, shape decisions just as much as buyer obsession does. Fees also serve to protect those operations, which in turn helps Amazon serve more buyers.
Now that philosophy can show up a little differently depending on who is running the operations. With FBA, sellers use Amazon’s operations and will be forced to optimize to their standards. Fees serve to protect Amazon’s customer goals and ensure optimal operations. With FBM, or Seller Fulfilled Prime, since sellers maintain control of their operations, programs, and fees are only directed at customer satisfaction. Sellers are free to choose which path they want. Each one has a tradeoff.
So every fee and program covered in this project gets read in two ways:
- What is the benefit to the customer experience?
- How does this enhance operational efficiency?
What This Means for Your Business
Every decision you make as a seller happens inside a system that has its own goals. A pricing choice, a shipping choice, a storage choice, each one interacts with something Amazon is already optimizing for. Once you understand what that is, you stop guessing whether a policy or a fee is arbitrary, and start seeing what it’s actually protecting, or what it’s pushing you to change.
This is the goal of Fee Intelligence. It’s not a rulebook to memorize, but a way to navigate the platform for yourself. Every fee and program on Amazon will be worked through one at a time, so the next policy update or fee change doesn’t have to be a surprise.
