Asset Purchase vs Stock Purchase for Ecommerce (2026)

An asset purchase means you buy the brand, listings, inventory, domain and contracts, and the seller keeps the company and its past. A stock purchase means you buy the company itself, including everything it ever did. For most ecommerce deals, especially anything on Amazon, the asset purchase is the structure I choose, and a stock purchase is the exception you need a reason for.

That is the short answer to asset purchase vs stock purchase. The rest of this post is how I decide, what each one means for Seller Central, Brand Registry and taxes at a general level, and what to write in the LOI. This is not legal or tax advice. I am an operator who has reviewed 50+ deals as a buyer. Have a lawyer and a CPA look at your specific deal.

Asset purchase vs stock purchase: what each one actually buys

Strip out the legal vocabulary and the difference is simple.

In an asset purchase, you and the seller agree on a list of things. The brand and trademarks. The listings and ASINs. The domain and store. Inventory. Supplier relationships. Customer data. Photography and design files. You pay for that list and nothing else. Whatever is not on the list stays with the seller's company.

In a stock purchase (also called an equity purchase), you buy the ownership of the company that holds all of it. You get the assets, and you also get the tax filings, the past product claims, the contracts nobody remembers signing and the marketplace account history. The company is the same company. Only the owner changed.

Question	Asset purchase	Stock purchase
What do you buy?	A defined list of assets	The whole company
Old liabilities	Stay with the seller by default	Come with the company
Paperwork at close	Each asset has to transfer	One ownership transfer
Contracts and accounts	Must be assigned or re-papered	Stay in place
Amazon seller account	Cannot be handed off, buyer relaunches	Do not assume it solves the account, confirm with counsel
Typical fit	Most small and mid-size ecommerce deals	The exception, when something cannot be assigned

The pattern in that table is the whole decision. An asset purchase costs you paperwork and buys you protection. A stock purchase saves paperwork and costs you protection.

The liability difference is the real reason

I do not choose a structure because it is faster. I choose it based on what I am willing to inherit.

When you buy a company, you buy its past. For an ecommerce business, that can include:

• Tax exposure. Anything the company under-reported or never filed is now your company's problem.
• Product claims. A product sold two years ago can still produce a claim. In a stock purchase that claim lives in the company you now own.
• Marketplace history. Suspensions, intellectual property complaints and account health problems attach to the seller's account and entity. I check this in diligence, and the ecommerce acquisition due diligence checklist covers the exact items: Account Health, suspension and reinstatement history, and open IP complaints.
• Contracts you did not read. Supplier, 3PL and agency agreements all come along.

In an asset purchase, none of that moves unless you write it into the agreement. That is the point. You decide what you assume, and you list it.

This does not make an asset purchase risk-free. A seller can still misrepresent what is on the list. That is an attorney question. But as a default, buying the assets and leaving the company behind is the cleaner starting position.

Why most ecommerce deals are asset purchases

First, you are usually buying a brand, not a corporate shell. What has value is the trademark, the listings, the inventory and the supplier relationships. The seller's entity is a container. I do not need the container.

Second, small ecommerce companies often have messy histories. I price what I can verify in diligence. I would rather not buy the parts I cannot.

Third, the marketplace rules now push you here. More on that below.

In my how to acquire an ecommerce business process, the structure sits between the LOI and diligence: you set it in the LOI, and diligence tests whether it still works.

What happens to Seller Central, Brand Registry, ASINs and reviews

This is the part generic M&A articles skip, and it is where ecommerce deals actually get stuck.

The Amazon seller account

You cannot buy a seller account and log in as the old owner. Amazon's Business Solutions Agreement update took effect August 24, 2026 and bans transferring a seller's rights or obligations under the agreement. I wrote up the details in what the Business Solutions Agreement 2026 update bans.

So the clean structure is an asset purchase: you form your own entity, get approved as a new seller, and relaunch the catalog under your own account. Build that approval timeline into your closing date, not after it. I make the same point in first 90 days after buying a business.

If a seller proposes handing you their login, the structure is the problem, not the price. A discount does not fix a prohibited structure. Restructuring does.

Brand Registry and the trademark

Brand Registry rides on the trademark. So the question to ask is who owns the mark and whether it can be assigned to your entity. Put the trademark on the asset list, confirm the owner of record, and have counsel handle the assignment. If the brand's trademark sits with a former founder or a contractor, find that out before the LOI, not at closing. The Amazon Brand Registry overview is where Amazon describes enrollment.

ASINs, listings and reviews

The catalog is the asset you are paying for, so list it explicitly. How listings and reviews carry over depends on how the catalog transition is handled with Amazon and what your counsel signs off on. I do not promise a buyer that reviews move cleanly, and neither should a seller. Treat review history as something to verify in the transition plan, and price the risk if it does not carry.

Tax treatment, at a general level only

I am not going to tell you what your tax bill will be. It depends on entity type, state, how the price is allocated and your own situation. What I can tell you is where the structure shows up.

In a US asset sale, the buyer and seller allocate the purchase price across asset classes and report that allocation to the IRS on Form 8594. That allocation is a negotiation, because the buyer and seller can each care about it differently. Buyers and sellers care about different parts of it, and those interests do not always line up.

A stock purchase does not require that same allocation exercise in the same way, which is one reason some sellers ask for it. Their CPA may prefer it. That is a legitimate reason to talk about the structure, and it is why the two sides need numbers from their own advisers before the LOI is signed.

My rule: never let a broker or a seller tell you the structure is "just standard" without your own CPA looking at the allocation. I compare the people who might run that process with you in business broker vs M&A advisor for ecommerce.

When a stock purchase is the right call

A stock purchase is the exception, but it is a real one. It makes sense when something valuable cannot be assigned, or assigning it would break the deal.

• A supplier contract that does not assign and the supplier will not re-sign.
• A license, permit or regulated category approval held by the entity.
• A long-standing account or relationship with real value that is tied to the company, not to a person.
• A seller whose advisers have a strong tax reason, where the buyer can price the added risk.

Notice the pattern. Each reason is about a specific asset that will not move. It is not a general preference. If you go stock purchase, you take on the seller's whole history, so the diligence has to be deeper, the representations and warranties have to be tighter, and the price should reflect the risk. A stock purchase without that extra work is the expensive mistake.

For Amazon, a stock purchase does not get around the transfer problem. The BSA language covers transferring rights or obligations, and how a change in company ownership is treated is a question to put to counsel and to Amazon directly. Do not assume a stock deal solves the account.

The advice I would ignore: "just pick what your broker prefers"

Whoever is running the process may favor the structure with the least paperwork, or the one they always use. Neither is a reason.

The better test is two questions:

1. What must transfer for this business to keep making money? That is your asset list.
2. What liabilities will I refuse to inherit? That is what rules out a stock purchase unless you are covered.

If the answer to the first question is mostly assignable assets and the answer to the second question is "all of them," you have an asset purchase. If a critical contract or approval will not move, you have a conversation about a stock purchase, with price and protections to match. Choose the structure on the deal, not on who is holding the pen.

What to put in the LOI and purchase agreement

Your LOI is where the structure gets written down, and my letter of intent to buy a business guide has the paste-ready clause text. For structure, my version says the buyer will buy the assets of the business and will not assume the seller's liabilities except those listed in the purchase agreement. I leave a note to change it only if counsel recommends a stock purchase.

Beyond that clause, make sure these are covered before you move to the purchase agreement:

• A named asset list. Brand, trademarks, listings and ASINs, domain, inventory, supplier relationships, customer data, creative files. If it is not listed, assume it does not transfer.
• An assumed liabilities list. Short. If something is not named, you did not assume it.
• Purchase price allocation. Agree the approach early, with both advisers in the loop, so it is not a fight at closing.
• Marketplace transition. Who forms the buying entity, who applies for seller approval, and what happens to the closing date if approval is slow.
• Seller representations and indemnity. What the seller promises is true, and what happens if it is not. This is attorney territory. Do not write it yourself.
• Price build. Cash, a seller note and any earnout, each stated. If you are weighing financing, compare it in seller note vs SBA loan for an ecommerce acquisition.

State the earnings figure the price rests on and whether it is SDE or EBITDA. See SDE vs EBITDA for ecommerce and how to value an ecommerce business. Sellers preparing for this conversation should read how to sell your Amazon FBA business.
