An investor or acquirer looking at an ecommerce business does not start with your revenue growth. They start with the numbers that predict whether revenue survives contact with new ownership. Seven metrics come up first in almost every diligence conversation, and a seller who has them ready changes the tone of the process.
The order below reflects roughly how quickly each one gets asked for.
1. Contribution margin by SKU
The first question is never “how much do you sell.” It is “what do you actually keep on each thing you sell.”
Buyers want per item economics: price, landed cost, channel fees, returns, and advertising allocated to the product that consumed it. What they are looking for is concentration risk. A catalog where three SKUs produce 80 percent of contribution margin is a different asset from one where forty products each carry weight, and it gets valued differently even at identical revenue.
Sellers who cannot produce this at the item level usually spend the first three weeks of diligence building it under time pressure, which is a bad moment to discover your cost data was never clean.
2. Revenue concentration across channels
A business doing everything on one marketplace carries platform risk that shows up directly in the multiple. One suspension, one policy change, one algorithm shift, and the asset changes character.
Buyers will ask for revenue and margin split by channel, usually 24 to 36 months of it. They are checking two things: whether diversification is real or cosmetic, and whether margins hold across channels or one channel is quietly subsidizing another.
3. Inventory turns and aged stock
Inventory is the largest asset on most product company balance sheets and the one most likely to be overstated.
The questions are predictable. How fast does inventory turn. How much of the current stock has been sitting more than 180 days. What is the realistic recovery value on the slow portion. Aged inventory carried at full cost is one of the most common diligence adjustments, and it comes straight off the purchase price.
4. Customer acquisition cost and payback period
For direct to consumer brands this is often the whole conversation. What does it cost to acquire a customer, how long until that customer pays it back, and what has happened to both numbers over the last eight quarters.
A rising acquisition cost against a flat repeat rate describes a business that has to run harder every quarter to stand still. Buyers can see that pattern in the data long before it shows up in revenue.
5. Gross margin stability, not gross margin level
A 38 percent gross margin that has held within two points for three years is worth more than a 45 percent margin that swung between 30 and 55.
Volatility signals unpriced input risk: freight exposure, currency, a supplier with pricing power, or a fee structure the seller does not control. Buyers model the low end of the range, not the average.
6. Quality of the financial records themselves
This one is less a metric than a gate, and it kills more deals than any single number.
The specific test is whether marketplace settlements reconcile to the books. Deposits are net of referral fees, fulfillment, storage, advertising, refunds, and reserve movements. A seller who books the deposit as revenue has understated both revenue and expenses, and every margin calculation built on top is wrong. Reconstructing two years of that during diligence is expensive and it damages the buyer’s confidence in everything else.
This is the problem the ecommerce accounting category exists to solve. Tools in the space, ConnectBooks and A2X among them, work by breaking settlement data into its component lines so the accounting system receives the actual transaction detail rather than a net figure. The distinction matters at exit because it determines whether your historical financials can be audited at all.
7. Cash conversion cycle
The last one tells a buyer how much working capital they will need to inject on day one.
Days from supplier payment to customer cash, including production, transit, shelf time, and marketplace payout terms. A business with a 140 day cycle needs materially more capital to run at the same revenue than one at 60 days, and buyers price that difference into the offer.
What sellers get wrong about preparing these
Two mistakes recur.
The first is starting six weeks before going to market. Every one of these seven metrics is a trailing series. A buyer wants to see 24 to 36 months, and you cannot retroactively produce clean SKU level margin history if the underlying cost data was never captured. Sellers who decide at the start of a year that they might transact within two years end up with a materially better process than sellers who decide in March that they want to close by June.
The second is presenting adjusted numbers without the bridge. Add-backs are normal and expected. Owner compensation, one-time legal costs, and genuinely non-recurring spend all get added back routinely. What damages credibility is presenting the adjusted figure as the headline without showing the path from reported to adjusted. Buyers assume anything they have to reconstruct themselves is hiding something, and they are often right.
The underlying pattern
Six of these seven are margin and cash questions. Only one touches growth.
That ratio surprises sellers who have spent years optimizing for revenue, and it is the most useful thing to take from the list. An acquirer is buying future cash flow and pricing the risk attached to it. Growth affects the multiple. Margin quality, record quality, and working capital intensity affect whether a deal happens at all.
Anyone running a process should also get a transaction-experienced accountant involved before the first conversation rather than after the letter of intent. The structure of a deal has tax consequences that vary by entity type and by state, and those are decisions to make with a professional who has seen the specific situation rather than from general guidance.
