Amazon FBA businesses remain one of the most popular categories in the online business acquisition market. The model is straightforward: you source products, send them to Amazon's fulfillment centers, and Amazon handles storage, picking, packing, and shipping. When the business runs well, it generates significant cash flow with relatively low day-to-day operational involvement.
But FBA acquisitions carry risks that content sites and SaaS businesses don't. Inventory sitting in Amazon warehouses is a real asset that can depreciate, get stranded, or become unsellable. Brand Registry protections can be challenged. Supplier relationships can deteriorate. And Amazon's ever-shifting policies mean that what's compliant today might be a violation tomorrow. This guide walks through every stage of an FBA acquisition — finding deals, valuing them correctly, conducting due diligence, and protecting yourself in the purchase agreement.
In an FBA business, the seller has built a brand that sells physical products through Amazon. Most established FBA businesses operate as private label brands — they source products from manufacturers (usually in China, Vietnam, or India), apply their own branding, and sell under their own Amazon brand name. Some FBA businesses also include direct-to-consumer sales through a Shopify store or their own website, which adds diversification beyond the Amazon channel.
Sellers typically exit for a few reasons: they've built the business to a profitable size and want to cash out at a multiple, they're tired of the operational complexity (sourcing, inventory management, PPC optimization), or they see margin compression in their niche and want to sell before it gets worse. Understanding the seller's motivation helps you assess whether the business is genuinely healthy or headed toward a structural decline.
FBA businesses are valued on a multiple of monthly SDE (Seller's Discretionary Earnings) or EBITDA, similar to other online businesses. Current market multiples for FBA businesses in 2026:
| Business Profile | Monthly Net | Multiple Range |
|---|---|---|
| Strong brand, diversified SKUs, 3+ year track record | $10K+ | 36x–48x monthly |
| Established, 2+ years, single niche, consistent revenue | $5K–$15K | 28x–40x monthly |
| Newer (1–2 years), some brand recognition, Amazon-only | $2K–$8K | 22x–32x monthly |
| Single-product, heavy reliance on one ASIN, under 1 year | Any | 18x–26x or pass |
One critical adjustment: FBA valuations must account for inventory separately. Most FBA business listings quote a purchase price that does not include the inventory value — inventory is typically paid at cost (what the seller paid for it) on top of the multiple-based price. If a business is listed for $400,000 and has $80,000 of inventory at cost, the true acquisition cost is $480,000. Always clarify upfront whether inventory is included or separate.
The most common — and most dangerous — structural weakness in FBA businesses is ASIN concentration. If one product (one Amazon Standard Identification Number) generates more than 40% of total revenue, the business is dangerously dependent on that listing. A single listing can be suppressed, hijacked, or damaged by bad reviews at any time, and the recovery process is slow and unpredictable.
Before making an offer on any FBA business, pull the revenue breakdown by ASIN for the trailing 12 months. A healthy FBA business has multiple SKUs with no single ASIN exceeding 25% to 30% of total revenue. If the seller's top ASIN is 60% or more of revenue, discount the multiple significantly or walk away — you're buying one product, not a business.
Amazon Brand Registry is the program that gives brand owners control over their listings — the ability to suppress unauthorized sellers, protect their brand name, and use A+ Content and Sponsored Brand advertising. A brand that is not in Brand Registry is dramatically more vulnerable to hijackers and counterfeit sellers undercutting the listing price.
During due diligence, confirm:
An FBA business is only as good as its supply chain. If the seller has a proprietary supplier relationship, exclusive product molds, or unique manufacturing agreements, those need to transfer to you cleanly. If the supplier is easily replaceable (generic products with no exclusivity), that's less of a risk, but also means more competition could enter the niche easily.
Request the following from the seller during due diligence:
Schedule a direct introduction call with the supplier before closing. Suppliers sometimes refuse to maintain exclusive arrangements or custom tooling agreements when ownership changes. Finding this out post-closing is catastrophic.
Request read-only access to the seller's Seller Central account during due diligence. Beyond revenue numbers, focus on these metrics:
Amazon assigns an Account Health Rating (AHR) score. A score above 200 is healthy; below 100 is at risk of deactivation. Look at the AHR history — if it's been in the red zone in the past 12 months and recovered, understand why and what changed. Accounts with a history of policy violations are more vulnerable to future problems.
The Voice of the Customer (VOC) dashboard shows customer experience (CX) health ratings for each listing. Products with "Poor" or "Fair" ratings have elevated return rates, and Amazon may suppress those listings to protect buyer experience. A "Poor" VOC rating on a top-selling ASIN is a flashing warning sign — that ASIN may have a product defect problem the seller hasn't disclosed.
Review the Order Defect Rate (ODR) metrics — A-to-Z Guarantee claims, credit card chargeback rate, and negative feedback rate. Amazon's thresholds are strict: ODR above 1% triggers account review; above 2% typically means deactivation. An account with consistently high ODR metrics is a platform risk that goes beyond individual products.
Most FBA businesses run Sponsored Products or Sponsored Brand campaigns. Pull the advertising reports and calculate the true ACoS (Advertising Cost of Sales) — what percentage of ad-attributed revenue goes to ad spend. Industry target: 20% to 35% ACoS. ACoS above 50% means the business is not profitably scaling ad spend, and net margins may be lower than the seller's SDE calculation suggests. Confirm that PPC costs are included in the SDE calculation, not excluded.
Inventory is the most complex part of an FBA acquisition. You're buying physical goods that can become stranded, age out, or require disposal fees. Here's how to properly assess the inventory you're acquiring:
Stranded inventory is inventory in Amazon's warehouses that cannot be sold because of listing errors, suppressed listings, or fulfilled by merchant (FBM) settings incorrectly applied. Check the Stranded Inventory report in Seller Central. Any significant stranded inventory is a liability — you're paying storage fees on goods that aren't generating revenue.
Amazon charges Long-Term Storage Fees (LTSF) on inventory that has been in warehouses for more than 271 days. Pull the Inventory Age report and flag any inventory that has been sitting for more than 180 days. These items either need to be sold quickly (often at a discount through price cuts or coupons) or removed from FBA warehouses. Budget for the cost of liquidating aged inventory when valuing the deal.
As noted above, inventory is typically paid separately at cost. Request a complete inventory report showing quantity on hand and cost-of-goods for each SKU. Verify the stated cost against supplier invoices — sellers sometimes overstate inventory cost to inflate the total consideration they receive at closing.
Amazon Seller Central accounts are technically non-transferable under Amazon's Terms of Service — you're not supposed to buy and sell accounts. However, in practice, FBA business acquisitions work through an entity transfer. Instead of buying the account directly, you acquire the LLC or corporation that owns the Seller Central account. The account itself doesn't change hands; the legal entity that holds it does.
This is why most FBA acquisitions are structured as stock purchases rather than asset purchases. You buy the equity in the entity that operates the Amazon account. This approach maintains account continuity, preserves the review history and performance metrics, and keeps Brand Registry enrollment intact.
The risk: with a stock purchase, you also inherit all the entity's liabilities — tax obligations, supplier disputes, any pending legal claims. Conduct proper legal due diligence on the entity itself, not just the Amazon business. Representations and warranties from the seller should cover all material liabilities, with indemnification if undisclosed liabilities surface post-closing.
The first three months after an FBA acquisition determine whether the business grows or declines under new ownership. The most important actions:
