Most buyers look at an ecommerce deal and anchor on the revenue number. Then EBITDA. Then the asking multiple.
They skip inventory.
That is a mistake that can cost you six figures at closing, or worse, leave you owning a business that looks profitable in the spreadsheet but is hemorrhaging cash inside a warehouse you have never set foot in.
Ecommerce inventory valuation is one of the most misunderstood line items in the entire acquisition process. Sellers treat it as a simple add-on. Brokers gloss over it. And buyers who do not dig in end up overpaying for product that may not be worth what anyone claims. Here is how the valuation actually works, how SBA lenders look at it, and what you need to do before you sign anything.
How SBA 7(a) Financing Treats Ecommerce Inventory
We are going to start here instead of the theory because this is where most buyers get surprised.
SBA 7(a) loans can finance inventory as part of a business acquisition. But the way lenders value that inventory for collateral purposes is not the way sellers value it on their balance sheet.
The SBA will typically assign a liquidation or orderly liquidation value to inventory, not cost basis. Their question is simple: if this business fails and we need to sell the inventory to recover our exposure, what do we actually get back? That number is almost always meaningfully lower than what you are paying.
What this means in practice: if you are acquiring a business at $1.4M with $300K in inventory included, the SBA lender may only attribute $150K to $180K in collateral value to that inventory. The remaining $120K to $150K in value gap has to be covered by other collateral or accepted as a partially uncollateralized portion of the loan.
This does not kill deals. We have closed plenty with significant inventory components. But it changes how your lender underwrites the transaction and may affect your loan terms, your equity injection requirement, or both.
One structure we use frequently on deals with heavy inventory: negotiate the inventory purchase as a separate line item outside the headline acquisition price, with the seller taking a partial seller note on the inventory component. Full standby, 0% interest on that seller note is the standard we push for, and we get there on 90% or more of our deals. This gives you flexibility in how the SBA loan is structured and keeps the goodwill-to-tangible-assets ratio in a range that lenders prefer.
Why Inventory Valuation Matters More in Ecommerce
In a service business acquisition, there is almost nothing physical to fight over. You are buying cash flow, customer relationships, maybe some equipment.
Ecommerce is different. You are buying stock. Physical product sitting in a 3PL warehouse or an Amazon FBA fulfillment center. That inventory has a dollar value, and that value changes the deal structure in ways most buyers do not think about until it is too late.
Say you are looking at an ecommerce brand doing $2.8M in revenue with $520K in reported seller discretionary earnings. The seller is asking $1.9M. On the surface, that looks like a 3.6x SDE multiple.
But here is the thing about SDE: it is a broker-friendly number. We discount SDE by 15% to 50% to get to real cash flow, depending on how aggressively the seller has added back expenses that a new owner will actually incur. On this deal, after adjusting for realistic owner compensation and non-recurring add-backs, the real cash flow might be closer to $370K to $440K. That changes the effective multiple significantly.
And the seller also wants you to buy $380K in inventory on top of the acquisition price.
So now you are looking at a $2.28M total transaction against adjusted cash flow that may be well below the headline SDE. Your SBA loan math, your equity injection, your DSCR, and your working capital needs (which you absolutely must budget for, typically 2 to 6 months of operating expenses in cash at close) all shift. Sometimes dramatically.
How the Valuation Gets Calculated
Ecommerce inventory valuation is the process of determining the fair market value of a business’s physical product stock at the time of acquisition. Sounds simple enough.
Three numbers matter:
Cost basis. What the seller paid to manufacture or purchase the inventory. This is the floor. You never pay more than cost for existing inventory.
Net realizable value. What the inventory will actually sell for, net of fulfillment costs, platform fees, and returns. For healthy inventory, NRV is above cost. For slow-moving stock, NRV can drop below cost.
Liquidation value. What you would get if you had to clear it all out at a discount. This is the number SBA cares about in downside scenarios, as we covered above.
In most ecommerce acquisitions, inventory transfers at cost basis. That is the market standard. But cost basis only tells you what the seller paid. Not what you should pay. A SKU that cost $8 to land but has been sitting for 14 months in an FBA warehouse accruing long-term storage fees and losing organic rank is not worth $8 anymore. It might not be worth $4.
The Four Categories That Determine Real Value
When we review ecommerce deals, we bucket every SKU into one of four categories. This is how you build a defensible ecommerce inventory valuation instead of just accepting whatever number the seller hands you.
Category 1: Active, fast-moving inventory. Sells through within 60 days based on trailing 90-day velocity. Full cost basis applies. No discount.
Category 2: Slow-moving inventory. Sells through in 60 to 180 days. Apply a 10% to 25% discount to cost basis depending on storage fees, carrying cost, and reorder cycles. This stuff is not dead, but it is not healthy either, and the carrying cost erodes its value every month.
Category 3: Stale inventory. Sells through in more than 180 days or has not moved in 90-plus days. Apply a 40% to 60% discount. This is a liability as much as an asset. If it is sitting in Amazon FBA, the long-term storage fees alone can eat a meaningful percentage of its cost basis over a year.
Category 4: Obsolete or unsellable. Discontinued SKUs, damaged goods, products being de-ranked on Amazon due to poor reviews, items with expiration concerns. Value: zero. Sometimes negative if it costs money to dispose of or remove from FBA.
Most sellers will not categorize their inventory this way on their own. You have to do it yourself during due diligence. Request a full SKU-level inventory report with 90-day, 180-day, and 365-day sales velocity data. If the seller cannot produce that report, treat it as a red flag about how they operate the business generally.
What to Negotiate and How
The seller’s asking price for inventory is almost never the right price.
That is not because sellers are dishonest. It is because most sellers do not run the category analysis above. They open QuickBooks, look at cost of goods on the balance sheet, and call it a number.
Your job is to do the work they skipped.
Here is a practical approach:
- Request full inventory data at the LOI stage. Make inventory transparency a condition of the LOI itself. Not after. At.
- Run the four-category analysis. Assign an adjusted value to each bucket.
- Calculate your total adjusted inventory value.
- Present that number to the seller with the underlying SKU data supporting it.
- Negotiate from there.
Sellers who cannot explain why their stale inventory deserves full cost basis typically come around. The data does the work for you.
On a deal we recently reviewed, a $2.1M ecommerce brand had $410K in claimed inventory value. After running SKU-level velocity analysis, we found $160K of it was slow-moving or stale. Our adjusted valuation came in at $275K. The seller eventually accepted $290K. That $120K difference changes the buyer’s equity injection and total deal cost in a real way. Not theoretical. Real dollars at close.
All of that matters. But none of it means anything if your financing model does not hold up.
DSCR and Inventory: Running the Real Numbers
Buyers get tripped up because they treat inventory valuation as a separate negotiation from the financing model. It is not separate. They are directly connected.
Here is a simplified example.
Target business: $2M acquisition price, $480K in reported SDE (which, after applying our standard discount, might come down to $340K to $400K in real cash flow, but we will use the higher end for illustration). Three years of clean books.
Seller wants $320K for inventory on top of the purchase price.
Total transaction: $2.32M. And that is before working capital. Budget another $40K to $80K in cash you will need on hand to operate the business post-close, depending on reorder cycles and supplier payment terms.
At 90% SBA financing with 10% equity injection, your loan is roughly $2.09M. At a 10-year term and current SBA rates, that works out to approximately $260K to $280K in annual debt service.
Your DSCR on $400K adjusted cash flow is roughly 1.43x to 1.54x. That is tight. Dangerously close to the 1.5x target we set as our minimum, and a lender using the unadjusted SDE would see a more comfortable 1.72x to 1.85x that does not reflect reality.
Now adjust the inventory to its actual value after category analysis: $210K.
Total transaction drops to $2.21M. Loan drops to approximately $1.99M. Debt service drops. DSCR improves. And you put less cash in at close, which means more working capital available to actually run the business.
The inventory negotiation is not a side conversation. It is a core piece of deal structuring.
Red Flags That Should Stop You Cold
A few patterns we see consistently that should trigger real caution:
Inventory count has not been audited in 12-plus months. Shrinkage, FBA damage claims, and returns create discrepancies between what QuickBooks says and what is physically in the warehouse. Always require a physical or system-reconciled count before close. Not optional.
Seller cannot provide SKU-level velocity data. If they are running an ecommerce business without this data, it raises serious questions about how they make purchasing decisions and how they operate the business more broadly.
High concentration in seasonal inventory. A business that does 60% of revenue in Q4 and is being acquired in Q1 may be carrying inventory that will not turn for 9 months. That carrying cost hits your cash flow before the business generates its peak revenue. You are financing dead weight for three quarters.
Inventory valued above current replacement cost. If the seller is valuing inventory at cost basis from 2 years ago but current landed costs have dropped (which happens, especially with products sourced from Asia where freight rates and raw material costs have fluctuated significantly since 2022), you are paying a premium for something you could replace cheaper today.
Amazon FBA inventory specifically. Amazon co-mingles products in some cases, and their damage and loss reimbursements do not always match reality. Reconcile FBA inventory reports against Amazon settlement statements before closing. We have seen discrepancies of 5% to 15% between reported inventory and actual usable stock. That adds up fast on a $300K inventory position.
Ecommerce Inventory in Asset vs. Entity Acquisitions
Whether you are buying assets or the entity itself changes how inventory flows through the deal.
In an asset purchase, which is the most common structure for sub-$5M SBA deals, inventory transfers explicitly and is separately valued in the asset purchase agreement. Your attorney documents exactly what transfers, at what value, on what date. Clean and straightforward.
In an entity acquisition (less common, but sometimes used when there are specific licenses, platform accounts, or contracts that cannot easily be assigned), inventory sits inside the entity automatically. But you still need a formal valuation for SBA underwriting and purchase price allocation purposes.
The IRS Form 8594 requires the buyer and seller to agree on how total consideration is allocated across asset classes. Inventory falls into a specific class (Class IV, if you want to look it up). Your CPA and attorney should be heavily involved in this allocation. Get it wrong and you create tax complications for both sides that persist well beyond closing.
For most ecommerce deals below $3M, asset purchases with clearly documented inventory transfers are the cleanest path.
Frequently Asked Questions
How is ecommerce inventory valued in a business acquisition?
Ecommerce inventory valuation in an acquisition is typically done at cost basis, meaning what the seller originally paid for the goods. But buyers should apply a velocity-adjusted discount that accounts for slow-moving, stale, or obsolete inventory. A full SKU-level analysis with 90-day and 180-day sales data is the minimum standard. Never pay cost basis for inventory without reviewing its actual turn rate first.
Will SBA finance the inventory purchase as part of an ecommerce acquisition?
Yes, SBA 7(a) loans can include inventory as part of the financed acquisition amount. However, SBA lenders will apply a liquidation or orderly liquidation value to inventory for collateral purposes, which is typically lower than cost basis. Buyers should understand this affects their loan-to-value calculation and may require additional collateral or structuring adjustments if inventory represents a large portion of the total deal.
What is a fair discount to apply to slow-moving ecommerce inventory?
It depends on velocity. Inventory that sells through in 60 to 180 days typically warrants a 10% to 25% discount to cost basis. Inventory with more than 180 days of supply on hand, or that has not moved in 90-plus days, should be discounted 40% to 60%. Fully obsolete or unsellable inventory is valued at zero. These are starting points for negotiation, not hard rules, but they are grounded in how the market actually prices this risk.
Should ecommerce inventory be included in the acquisition price or treated separately?
Both approaches work, and each has implications for your SBA loan structure, equity injection, and DSCR. Including inventory in the headline acquisition price simplifies the deal but can inflate goodwill allocation. Treating it as a separate line item gives you more structural flexibility, especially for SBA underwriting and seller note structuring. Work with your advisor and CPA to determine which approach fits your specific transaction.
What due diligence documents should I request for inventory in an ecommerce acquisition?
Request a SKU-level inventory report with 90-day, 180-day, and 365-day sales velocity data, the most recent physical or system-reconciled inventory count, FBA inventory reports reconciled against Amazon settlements if applicable, landed cost documentation for all active SKUs, and any pending supplier purchase orders that affect what inventory exists at close. If the seller cannot provide these, treat it as a material due diligence gap.
Thinking About Acquiring an Ecommerce Business?
Ecommerce acquisitions have real appeal. Scalable operations, digital-first cash flows, often minimal physical overhead compared to brick-and-mortar. But they come with wrinkles that traditional business acquisitions do not, and inventory is one of the biggest.
We run the full acquisition process for buyers: deal sourcing, financial modeling, inventory diligence, SBA financing, and close management. The ecommerce inventory valuation piece is just one part of a much larger picture, but it is the part that catches people off guard most often.
