Stepping into the US small business acquisition market, the first number that jumps out on every listing is cash flow or SDE — and first-time buyers typically make the same mistake: treating it like profit on an accounting statement. It's not. SDE is a processed number — legal and standardized — but processed by the seller's side, with incentive to make it as large as possible.
Understanding that processing method isn't about doubting everything, but about doing the buyer's job right: peeling back each layer of add-backs, keeping the legitimate ones, removing the cosmetic ones, and reconstructing your own number — because everything that follows (purchase price, capital plan, and even projections in the business plan of an L-1A application) stands on this number, not the advertised one.
This article moves from the definition of SDE, through a classification table of add-backs, to the process of reconstructing the number yourself and the questions to ask the seller.
What is SDE and why it differs so much from accounting profit
SDE (Seller Discretionary Earnings) answers the question: how much total does an owner who directly operates this business pocket each year? The basic formula: pre-tax profit + owner's salary and benefits + depreciation and non-cash items + interest expense + one-time or personal owner expenses.
The logic of reverse-addition: small US businesses are typically optimized by owners to reduce taxable profit — owner salary is set high, personal vehicles and phones run through the company, some household expenses get mixed in — so profit on the tax return is lower than actual earning power. SDE reverses that process to reveal true earning power — and precisely because it's a manual reversal process, it's where the seller's creativity has room to play.
Add-back classification table: legitimate, gray area, and cosmetic
- Legitimate (add back with confidence): salary + payroll taxes + benefits of an operating owner, depreciation, interest on debt that won't follow the business, documented personal expenses (private vehicle insurance, family travel miscategorized).
- Gray area (add back partially, ask carefully): one-time expenses per seller's claim — major repairs, litigation, relocation costs; verification question: is this truly one-time or is it a once-every-few-years cycle in this industry?
- Cosmetic (subtract outright): salary of family members working without actually receiving pay (the buyer will have to hire a replacement — that's real cost), work the owner does far beyond one position (owner as chef and accountant and manager — replace with how many salaries?), unreported cash revenue with no paper trail.
Golden rule: each add-back must answer this question: after I buy, will this expense truly disappear? If you can't answer it, don't add it back.
Reconstructing your own SDE: the four-source verification process
Don't edit the broker's spreadsheet — build a new one from source documents: three years of tax returns (the backbone — numbers filed with the IRS are your anchor), internal profit-and-loss statements each year (reconcile discrepancies with tax returns and demand explanations), business bank statements (does actual cash flow match reported revenue?), and POS system data if the industry has it (restaurants, retail — daily revenue doesn't lie).
From four sources, calculate your own SDE for three years and look at the trajectory: stable or slightly growing SDE is normal; SDE that jumps exactly in the year of sale is a classic red flag (revenue pulled forward, expenses deferred to make the final year look good). The gap between your calculated number and the listing number is the substance of price negotiation — and a test of the seller's honesty.
The question set to ask the seller: listen to answers, read reactions
- Each add-back line: where's the documentation, and why will this expense not exist when I operate?
- How many hours per week do you work, doing exactly what? (reconcile against owner salary add-back and the replacement problem)
- Who on the team is family, and how are they paid? (expose add-back number one)
- What percentage of revenue is cash, and how do you prove it? (the only standard answer: by numbers you reported — unreported revenue doesn't count as money when you sell, that's the market's fairness principle)
- Why are you selling, and how long will you support the transition?
A decent seller answers these with documents and specific numbers; a seller who dodges, changes the subject, or gets angry — that reaction itself is data, and usually decisive data.
The multiple applied to SDE: the other half of the price equation
Real SDE is only half the valuation equation — the other half is the multiple that the market pays for the industry and specific configuration: typical small businesses trade around 2-3.5x SDE, shifting based on factors familiar from the due diligence chain — owner dependency, customer concentration, lease quality, revenue trajectory, and the cleanliness of the numbers themselves.
Practical application: the same $200k SDE, a business with existing management, dispersed customers, and a long lease deserves a higher multiple than a business where the owner does everything with one customer representing half the revenue — and due diligence findings therefore have double impact on price: adjusting both SDE and the multiple. Understanding this two-part equation means speaking the same language as the broker in every round of negotiation.
From real SDE to every decision that follows: price, capital, and applications
Self-constructed SDE is the input to a chain of decisions: offer price (multiply the industry multiple by your SDE, not the listing's — the valuation section goes deeper), working capital plan (real SDE 20% lower than advertised means your cash cushion needs to be proportionally thicker), and market salary for positions you must hire to replace the old owner's work — new expense lines your model must absorb.
For L-1A applications, this number has another role: financial projections in the acquisition business plan rest on real SDE plus your plan — consistent numbers from the acquired company's tax returns through to USCIS projections is the kind of consistency that officers value most, because it's verifiable from independent sources.

Frequently Asked Questions
How does SDE differ from EBITDA?
Same family but different by one large item: SDE adds in the salary and benefits of an operating owner (assumes the buyer will be the operating principal), EBITDA does not (assumes hiring a manager). Small businesses trade on SDE; larger businesses on EBITDA. When comparing valuation multiples across sources, make sure both sides are speaking the same standard.
The seller says cash revenue is higher than reported tax numbers — how do you calculate that?
The market's fairness principle: unreported revenue doesn't count as money when you sell — the seller can't both enjoy the tax benefit of hiding revenue and demand the buyer pay for it. Value based on provable numbers (tax returns, POS, bank statements); the verbal part doesn't exist, and the fact that it's being mentioned is itself a red flag about that business's bookkeeping culture.
Which add-back gets abused most often?
Two champions: one-time expenses (repairs, upgrades claimed as unusual when they're actually a once-every-few-years industry cycle) and unpaid family labor (wife at the counter, son making deliveries — the buyer will have to hire replacements at market wage). The universal test for any add-back: after I buy, does this expense truly disappear?
My calculated SDE is 25% lower than the listing — should I walk away?
Not necessarily — the gap is a negotiation starting point, not a reason to leave: present your spreadsheet with each line documented and make an offer based on your number. The seller's reaction determines the next step: honest adjustment is a good signal; insisting on unproven advertising numbers — that's when you leave the table.
