Carving an Amazon Brand Out of an Aggregator: The Physical Inventory Checklist

By Bernardo Campelo, Forbes Business Council E-Commerce Leader, Amazon SPN Certified provider, Amazon SP-API authorized partner, and Founder of PrepVia.

The call usually comes a week or two after the deal closes. You own the brand on paper. The purchase agreement is signed and the money has moved. Then someone on your team asks the question nobody priced: where is the inventory, and when can it go to Amazon under our account?

Nobody has a clean answer. Some of the stock sits in a 3PL the aggregator shared with its sister brands. Some sits in fulfillment centers under the aggregator's seller account. A container may still be on the water. And every stickered unit wears the old owner's Amazon barcode.

A carve-out, or a founder buying a brand back, is a legal transaction first. It becomes a warehouse problem the minute it closes. Before you send one carton to FBA, every unit needs three answers: where it sits, whose account controls it, and whose barcode it will carry.

Why 2026 Carve-Outs Break at the Warehouse

Carve-outs come in three shapes, and 2026 put each one on the public record. The first is the asset buyer. On September 15, 2026, Nexxus Capital announced the finalization of a transaction originally completed in February 2026 for the assets of four brands from a major Amazon aggregator it does not name. Nexxus says the four brands generated over $33 million in revenue over the last 12 months. That is the buyer's own figure.

The second is the buyback. In an Operators podcast episode published February 4, 2026, Beast Gear founder Ben Leonard describes selling the brand to Thrasio in 2019 and buying it back. Revenue had fallen from $6 million to barely $500,000 after the website, email marketing and social media were shut down. A founder who buys back a brand like that also buys back whatever stock and labels sat through the decline.

The third is the restructured seller. BeautyMatter reported on June 29, 2026 that Olsam, which raised $165 million in 2021, restructured and rebranded as Avenir Collective, backed by NorthWall Capital. In BlackRock TCP's schedule of investments as of June 30, 2026, Razor appears as Infinite Commerce Holdings LLC (Razor). Names change. If the entity on the storage agreement does not match the entity on your purchase agreement, the warehouse release is where you find out.

In all three shapes, the legal closing and the physical closing happen on different days. Units go missing in that gap. Storage keeps billing in that gap. And the first shipment under the new owner goes out with the wrong barcode in that gap.

Goods, Identities, Accounts: What a Warehouse Can Move

Split the brand into three layers. The goods are units, cartons and pallets. The identities are what is printed or stuck on them: the GTIN, the old Amazon barcode, any Transparency code, the case labels. The accounts are the records inside Amazon: the seller account, the offers, the FBA inventory and the Brand Registry roles.

A warehouse can move the first layer and change the second. It cannot touch the third. FBA inventory is not one more warehouse location you can redirect. Amazon's FBA barcode choice and labeling FAQ says that with commingling ended, customers who buy from a seller receive only products from that seller's inventory, including returns and removals.

Here I have to be precise about what I do not know. Amazon's Business Solutions Agreement says a seller may not assign the agreement without Amazon's prior written consent, and an attempt in violation is void. The exception is assignment to the seller's own affiliates upon notice to Amazon. The agreement describes no procedure for moving an account, a listing or FBA inventory between sellers. I could not find a public help page that does.

So this checklist stays physical. Get the account answer from your counsel and from Seller Support, in writing, before any physical step depends on it. Your warehouse plan should work whatever that answer turns out to be.

The Location Census: Where Every Unit Sits on Closing Day

Start with a census, not a count. A count tells you how many units exist. A census tells you where each one sits, who controls it, and what it needs before FBA. Build it the week before closing if the deal allows it.

Two rows cause most of the trouble: the shared 3PL and FBA. Before anything leaves Amazon, get the old account's position by FNSKU and site, dated to the closing. The Amazon Inventory Ledger is the report that settles what was there that day. Keep a copy.

The Old 3PL: Release Letters, Liens and Sister-Brand Stock

The aggregator's 3PL has no contract with you. It holds goods for the aggregator entity, so expect it to release them only on that entity's written instruction. Get a signed release naming the brand, the SKUs, the quantities and the pickup party. Get it from the entity actually on the storage agreement.

Then ask about money. Under Section 7-209 of the Uniform Commercial Code, as published by Cornell's Legal Information Institute, a warehouse has a lien against the bailor, the party that stored the goods, for storage, transportation, labor and other charges related to them. If the bailor owes similar charges on other goods and the storage agreement claims a lien for them, the lien reaches those charges too. And a warehouse loses its lien on goods it voluntarily delivers or unjustifiably refuses to deliver. That is why a 3PL with an unpaid portfolio invoice has every reason to keep your truck waiting.

How that applies in your state is a question for counsel. Your job is to learn what the aggregator owes before you book the pickup. The exit terms in that storage agreement belong to the aggregator, so read what it signed.

Sister brands are the second trap. Brands in one portfolio can share a supplier, and sometimes a UPC. The collision in our aggregator onboarding playbook runs in reverse here: a pick by UPC can pull another brand's units into your transfer. Ask for picks by internal SKU and lot. Then count again on arrival, by carton and by unit, the way real counts versus said-to-contain explains.

Take the packaging too. Polybags, inserts, printed boxes and case labels rarely appear on the inventory report. Old Amazon barcode labels printed for the aggregator's account are different. Destroy them or return them. Never mix them into your label stock.

Stock Inside Amazon: Sell Through, Remove, or Dispose

FBA inventory under the old account is the one location your warehouse cannot reach. The parties have three options, and the choice belongs in writing. The old account sells it through for an agreed period. It removes the units to your warehouse. Or it disposes of units not worth moving.

Removal is what the public pages describe. Amazon's remove inventory overview says removal orders are typically processed within 10 to 14 business days, and 30 days or more in the holiday season. Amazon's FBA removal order fees page is slower: 14 business days, 30 business days or more at holiday and peak removal periods, then two more weeks for the carrier. Units stay available to buy until removed, so the old account closes the listing if it wants no sales. The removal address cannot be changed once the order exists. The overview says a seller can have inventory returned to itself or a designated recipient, and its restrictions list the seller, its warehouse, its supplier or its distributor, never another fulfillment center.

Three details from the overview shape your receiving plan. Case-packed inventory comes back as individual items. Units from several sites may arrive in multiple shipments from different carriers. Large removals come palletized by freight carrier, to a dock, with a signature at delivery. The 2026 removal orders guide covers claims when units go missing.

The fee is per unit, by shipping weight. For orders placed on or after January 15, 2026, Amazon's 2026 removal fee table lists $0.84 for standard-size items up to 0.5 lb, $1.53 above 0.5 lb up to 1 lb, $2.27 above 1 lb up to 2 lb, and $2.89 plus $1.06 per pound above 2 lb. Special handling items, which Amazon says may include apparel, shoes, watches, jewelry and dangerous goods, use the large bulky card, from $3.12. The removal order fees page rounds shipping weight up, to the next 0.1 lb for standard-size units under 1 lb and to the next whole pound otherwise, and since March 1, 2026 it charges the fee as each unit is removed. The overview adds that units in a removal order stop incurring storage fees while it processes.

Then plan the tail. Under Section F-6.2 of the FBA Service Terms, sellable customer returns go back into the inventory of the seller whose units they were, so returns on the old account's orders land in the old account. Agree who reviews them, how often they are removed, and where they ship.

AWD stock leaves by a different door. Amazon's Multi-Channel Distribution page says MCD moves inventory in bulk from AWD to the seller's own warehouse or a third-party warehouse, at a commercial address and never an FBA fulfillment center, as small parcel cartons or pallets with order minimums. The old account sets up that destination, so put it in the same written agreement.

The Relabel Decision: Brand Representative or Reseller on Day One

This is where the 2026 rules bite. Amazon's FBA barcode requirements say that as of March 31, 2026, brand owners can keep using manufacturer barcodes without stickers, while resellers must use Amazon barcodes. The manufacturer barcode page adds three conditions: new condition, one scannable UPC, EAN or ISBN matching one ASIN, and a brand enrolled in Brand Registry where the seller is a brand representative.

That last condition is your problem. On the day you want to ship, your account may not yet hold the brand representative role. The barcode FAQ says all resellers, authorized ones included, must use Amazon barcodes, and it points to Brand Relationships in Seller Central to verify roles. Until the role shows there, plan every unit as stickered. Our post on the manufacturer barcode crackdown covers the rest.

Three more details. Enrolling a brand does not automatically connect its products; you must register them to the brand. The account-level barcode preference takes about 24 hours to take effect, applies only to new offers, and cannot be changed for existing offers or shipments already created. And GTIN-exempt products always need Amazon barcodes. Brand Registry itself, per Amazon's enrollment page, needs a pending or registered trademark from the office of a country with an Amazon store. Whether the trademark moved with the brand is for your purchase agreement and your counsel.

Transparency adds a layer. Amazon's Transparency program page says that once products are protected, a valid code must accompany every unit listed or shipped in supported stores, and enrollment runs on Brand Registry credentials. Settle who orders codes after closing, and see how serialized labels work at a prep center. When the crew relabels, the Amazon barcode label rules say to cover all other visible barcodes except serial number barcodes and Transparency codes.

Do not plan on Amazon as your labeler. Its FBA Prep Service page says that starting January 1, 2026, Amazon no longer offers prep and item labeling for US FBA shipments. Shipments created after that date that arrive without proper prep and labeling are not eligible for reimbursement if damaged or untraceable. A unit that needs an Amazon barcode and arrives without one is marked defective, stickered by Amazon, and reported on your Inbound Performance Dashboard. Amazon's label rules require removable adhesive, so an old sticker printed to that rule should peel. When one tears, cover it.

The Transition Sequence, Step by Step

The order matters more than the speed. Each step removes one unknown before the next one spends money.

This is the part a prep center actually does. PrepVia receives the transfer from the old 3PL and the removals from Amazon at 8507 NW 72nd St in Miami. Transfers are counted against the packing list and the BOL, removals against the removal order ID, units are inspected and sorted by condition, and discrepancies are reported with photos within 24 hours of arrival. When the FNSKU changes account, old labels are removed or covered and the new FNSKU is scan-verified before the units go back to FBA under the new account, with a prep window of 24-36 hours. We do not move accounts, listings or Brand Registry roles, and we do not advise on the deal.

Frequently Asked Questions

Can the new owner move the aggregator's FBA inventory straight into its own account?

Not through any public procedure I could find. Amazon's Business Solutions Agreement requires Amazon's prior written consent to assign it, except to affiliates upon notice, and it describes no procedure for moving listings or FBA inventory between sellers. What the public pages do describe is removal, relabeling and a new inbound. Ask counsel and Seller Support how it works in your deal.

Do carved-out units need new barcodes if they already carry a UPC?

Usually, at first. Since March 31, 2026, only brand representatives in Brand Registry can use manufacturer barcodes without stickers, and resellers, authorized ones included, must use Amazon barcodes. If your account lacks the brand representative role on the day you ship, label every unit with your own Amazon barcode and cover the old ones.

How long does it take to pull a brand's inventory out of FBA?

Amazon's removal overview says 10 to 14 business days, and 30 days or more in the holiday season; its removal fee page says 14 business days, 30 or more at peak, plus about two weeks for the carrier. Units from several sites can arrive in separate shipments from different carriers, and case packs come back as single items, so add receiving and rebuild time before the stock is ready for a new inbound.

What does it cost to remove FBA inventory in 2026?

For removal orders placed on or after January 15, 2026, Amazon charges $0.84 per unit for standard-size items up to 0.5 lb, $1.53 up to 1 lb, $2.27 up to 2 lb, and $2.89 plus $1.06 per pound above 2 lb, with shipping weight rounded up. Special handling items start at $3.12. Since March 1, 2026, the fee is charged as each unit is removed, and storage fees stop on units in a removal order while it processes.

Can the old 3PL hold the carved-out brand's stock?

Plan as if it can. Section 7-209 of the Uniform Commercial Code gives a warehouse a lien against the bailor on stored goods for related charges, and the lien can reach charges on other goods when the storage agreement says so. How that applies to your deal is a question for counsel. Operationally, confirm what the aggregator owes before you schedule a pickup.

Where can removed FBA units be shipped?

Amazon's overview lets a seller have inventory returned to itself or a designated recipient, restricts returns to the seller, its warehouse, its supplier or its distributor, never another fulfillment center, and locks the address once the order is created. Confirm the receiving warehouse and its dock before anyone files, because large removals arrive palletized by freight carrier and need a signature at delivery.

Final Take

A carve-out closes twice. Once on paper, when the agreement is signed. Once on the dock, when the last unit is counted, released, relabeled and received under the account that will sell it. Most of what goes wrong goes wrong between those two dates.

The census is the whole method. Every unit gets a location, a controller and an identity before anyone books a truck. The account layer goes to counsel and Amazon in writing, because I cannot tell you how it moves and I will not guess.

The 2026 rules make the label decision sharper. If your account is not a brand representative on the day you ship, every unit carries your Amazon barcode, and a missing label is a defect, not a service. Decide on removal early, count everything twice, and ship small before you ship big.
