The Amazon FBA Dependency Problem Nobody Warns You About

Amazon FBA can be the fastest route to real customers a small brand will ever get, and it is also one of the deepest single dependencies you can take on. Your traffic, your storage, your shipping, your reviews, and your payouts all sit inside one company that changes its fee schedule every year and also sells competing products. FBA is a fine place to start. It is a dangerous place to end.

What you are actually signing up for

New sellers hear "Fulfillment by Amazon" and picture a logistics service. Send inventory, Amazon ships it, done. That framing hides what the relationship really is.

Amazon is your landlord (storage), your mall (the marketplace where buyers find you), your payment processor (payouts on their schedule), your reputation system (reviews you cannot export or take with you), and your rule-maker (terms of service enforced by automation). Every one of those roles is a lever the same company holds over your business.

None of this makes Amazon villainous. It makes Amazon rational. The risk is yours for not noticing the structure.

The fee ratchet only turns one way

Amazon publishes its fee schedule openly, and it updates that schedule every year. The direction of travel is consistent.

Referral fees run roughly 8 to 15 percent of the sale price depending on category, with 15 percent the most common. Fulfillment fees cover picking, packing, and shipping, and they rise with size and weight. Monthly storage fees climb sharply in the fourth quarter, right when you hold the most inventory.

Then there are the structural additions. In 2024 Amazon introduced an inbound placement service fee, charging sellers for how they route inventory into the fulfillment network, and a low-inventory-level fee that penalizes you for carrying too little stock, on top of the existing penalties for carrying too much. Sellers woke up to a cost stack that looked nothing like the one they had modeled a year earlier.

The current schedule lives on Amazon''s own FBA pages, and it is worth reading line by line before you model margins. The lesson is not the exact numbers. The lesson is that your unit economics are a document someone else edits annually.

The landlord also competes with you

Amazon operates private-label and exclusive brands across dozens of categories. Whether it uses individual seller data to pick those products has been contested for years. In a July 2020 House Judiciary hearing, Jeff Bezos was asked directly whether Amazon uses third-party seller data to benefit its own products. His answer, on the record: Amazon has a policy against it, but "I can''t guarantee you that that policy has never been violated."

You do not need to resolve that debate to plan around it. The structural fact stands on its own: the platform that ranks your listing, controls your buy box, and sets your fees also sells products in your category, with placement advantages you will never have. Plenty of categories are unaffected for years. Then a basics-brand listing appears above yours.

Your account is a single point of failure

Ask any seller forum what keeps people up at night and it is not fees. It is suspension.

Accounts get flagged by automated systems for inauthentic-product complaints, review manipulation, or paperwork mismatches, sometimes from a single bad-faith competitor report. Funds freeze while you appeal. The reviews you spent years earning belong to the listing, which belongs to the platform. Your customer list is not yours in any usable form: Amazon''s terms restrict contacting buyers outside their messaging system, and marketing to them directly can cost you the account.

If Amazon is 90 percent of your revenue, your business has one off switch, and you do not hold it.

When FBA is still the right call

Here is the part the doom posts skip. FBA is genuinely excellent for specific jobs.

It gives you Prime shipping speeds that convert browsers into buyers, which matters enormously when you are testing whether anyone wants the product at all. It removes fulfillment work so a solo founder can run real volume. It is one of the cheapest places on earth to find out whether a physical product has demand, because the buyers are already there with their cards saved.

The mistake is not using FBA. The mistake is letting FBA be the whole business forever.

The exit posture

The healthy pattern looks like this. Start on Amazon because that is where the buyers are. Use the early revenue to build what Amazon cannot take: a brand site with its own email list, a presence in at least one other channel, and a product line deep enough that one listing getting suppressed does not end you.

Watch three numbers monthly: what share of revenue is Amazon, what share of margin goes to Amazon fees, and what would happen to cash flow if the account froze for sixty days. If the third answer is "we close," you do not have an Amazon strategy. You have an Amazon dependency.

Run the dependency math before the platform runs it for you. Our free Reality Check counts exactly this: how many companies have to say yes for your idea to work, and what happens to the score when one of them also competes with you.

Frequently asked questions

Is Amazon FBA still profitable in 2026?

Yes for sellers with real margins and differentiated products, and increasingly brutal for resellers of generic goods. Referral and fulfillment fees have risen steadily, and 2024 added inbound placement and low-inventory fees. Profitability depends on whether your margin survives a fee schedule you do not control.

How much of my revenue should come from Amazon?

There is no magic number, but past about 70 percent you are an Amazon business with a side brand, not a brand that sells on Amazon. The practical test is the sixty-day question: if your account froze for two months, would the company survive?

Does Amazon really compete with its own sellers?

Amazon operates private-label and exclusive brands in many categories. At a 2020 congressional hearing, Jeff Bezos said Amazon has a policy against using individual seller data for that, but could not guarantee the policy had never been violated. Whether or not data misuse occurs, the platform competing with its tenants is structural.

What is the first move to reduce FBA dependency?

Build an owned email list and a direct site while Amazon revenue funds it. Amazon''s terms restrict marketing to buyers directly, so this usually means a brand presence buyers seek out themselves: content, packaging that earns searches for your name, and a site worth visiting.
