Reading the Seller's Numbers: SDE, Add-Backs, and the Art of Seeing Through Advertised Cash Flow

When you step into the market to buy a small business in the US, 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 every incentive to make it as large as possible.

Understanding that processing isn't about doubting everything; it's about doing your job as a buyer: peeling back each layer of add-backs, keeping the legitimate ones, removing the cosmetic ones, and rebuilding your own number—because everything that follows (purchase price, capital plan, and even the financial projections in your L-1A business plan) 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 rebuilding your own number 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 does an owner who directly operates this business put in their 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 expenses of the owner.

The logic of reverse-addition: small businesses in the US 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 because it's a manual reversal process, it's where the seller's creativity has room to play.

The 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, personal expenses with clear documentation (personal vehicle insurance, family travel miscategorized).
• Gray area (add back partially, ask carefully): one-time expenses per seller's claim—major repairs, litigation, relocation costs; the test question: is this truly one-time or is it a cycle that happens every few years in this industry?
• Cosmetic (subtract directly): salary of family members doing real work but not 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 bookkeeper—replace with how many salaries?), cash revenue reported verbally with no paper trail.

The 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.

Rebuilding 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 for each year (cross-check variance with tax returns and demand explanations for every discrepancy), 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 these four sources, calculate SDE for three years and look at the trajectory: stable or gently rising SDE is normal; SDE that jumps sharply in the year it's being sold 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

• For each add-back line: where's the documentation, and why will this expense disappear when I operate?
• How many hours per week do you work, and doing exactly what? (cross-check against owner salary add-back and the replacement math)
• Who on the team is family, and how are they paid? (exposing the number-one cosmetic add-back)
• What percentage of revenue is cash, and how do you prove it? (the only correct answer: by the number you filed—unreported revenue doesn't count as money when you sell, the fairness principle of this market)
• Why are you selling, and how long will you support the transition?

Honest sellers answer these questions with documents and specific numbers; sellers who dodge, change the subject, or get defensive—their reaction itself is data, and usually decisive data.

The multiple applied to SDE: the remaining piece of the price equation

True 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 due diligence—owner dependency, customer concentration, lease quality, revenue trajectory, and the cleanliness of the numbers themselves.

Practical application: the same $200k SDE in a business with an operating manager in place, 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 hit price twice: 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 true SDE to every decision that follows: price, capital, and your application

Self-built 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 (true SDE 20% lower than advertised means your cash cushion needs to be proportionally thicker), and market salary for positions you'll need to hire to replace the old owner's work—new expense lines your model must carry.

With an L-1A application, this number plays another role: financial projections in your acquisition business plan rest on true SDE plus your own plan—consistent numbers from the acquired business's tax returns through to your USCIS filing is the kind of consistency that officers value most, because it's verifiable from independent sources.
