The short answer: A listing is marketing. Read it in this order, (1) SDE (the real earnings number), (2) the multiple (price ÷ SDE; ~2.7× is typical at the small end), (3) the add-backs (are they legitimate?), and (4) the story ("owner absentee," "motivated seller," "room to grow" all mean something specific). Then hunt for the red flags: owner dependence, customer concentration, and declining revenue dressed as upside.
First, remember what it is
A business-for-sale listing is written by a broker who gets paid when it sells. Every word is chosen to attract buyers and justify the price. That doesn't make it dishonest, it makes it optimistic. Your job is to translate the optimism back into reality before you spend weeks in diligence. Start with the numbers, then decode the language.
Start with SDE, the number that matters
SDE (seller's discretionary earnings) is the total benefit a single full-time owner-operator gets from the business. It's net profit, plus the owner's salary, plus interest, taxes, depreciation, and legitimate add-backs. Almost every small business is priced as a multiple of SDE, so this is the foundation of everything else. If a listing quotes "revenue" prominently but buries SDE, that's your first clue to dig.
Then check the multiple
Divide the asking price by SDE to get the multiple. At the small-business end, a typical figure is around 2.7× SDE, with the exact number varying by industry, size, and quality. A recurring-revenue business with clean books commands a higher multiple; a fragile, owner-dependent one should command less. If the multiple is well above the norm for its category, the listing owes you a very good reason.
| Listing says | Figure | What you actually check |
|---|---|---|
| Asking price | $945,000 | Is it a multiple you can defend? |
| SDE | $350,000 | Verify against tax returns, not just the P&L |
| Implied multiple | 2.7× | In line with small-biz norms, reasonable starting point |
| Add-backs in that SDE | $90,000 | Legitimate, or padding the earnings? |
Scrutinize the add-backs
Add-backs are expenses the seller adds back to profit to show your "true" earnings, the owner's salary, one-time legal costs, a personal vehicle run through the books. Legitimate add-backs are fair game. But add-backs are also where SDE gets inflated: the more a seller adds back, the higher the SDE, and the higher the price they can justify. Treat every add-back as a claim to verify, not a fact.
Add-back red flags
Be skeptical of add-backs that are large, vague, or recurring, "miscellaneous owner expenses," ongoing costs labeled "one-time," or family members on payroll who don't work there. If removing the questionable add-backs sinks the DSCR, the real price is lower than the sticker.
Decode the broker language
Certain phrases show up again and again. Here's what they usually mean:
- "Owner absentee" / "semi-absentee." Sometimes true and great; often optimistic. Verify how many hours the owner really works and who holds the key relationships.
- "Motivated seller." Could be a genuine retirement (the silver tsunami is full of these), or pressure to move a problem. Find out why they're selling.
- "Room to grow" / "untapped potential." Frequently a polite way to say growth has stalled. Upside is real only if you can name the specific lever.
- "Turnkey." Ask what breaks the moment the current owner walks out the door.
- "Seller financing available." A genuine positive, it can lower your cash down and signals the seller believes in the business.
The red flags that should slow you down
None of these automatically kills a deal, but each one changes the price you should pay or the diligence you should demand:
- Owner dependence. If the business is the owner, their relationships, their expertise, the value walks out with them. This is the number-one risk in retiring-owner deals.
- Customer concentration. One client at 40% of revenue is a single point of failure. Ask for a revenue-by-customer breakdown.
- Declining revenue framed as opportunity. "Room to grow" over a three-year downtrend is a warning, not a pitch.
- Missing or "recast-only" financials. No tax returns, no clean P&L, walk until they appear. Verify SDE against filings.
- An off-market multiple. Far above the norm for the industry and size needs an ironclad justification.
- Urgency pressure. "Another buyer's circling" may be true, but never let it rush your underwriting.
The listing tells you what the seller wants you to feel. The financials tell you what's true. Trust the second one.
A quick first-pass workflow
- Find SDE. If it's not obvious, that's information in itself.
- Compute the multiple. Compare it to industry norms.
- List the add-backs and flag any you'd need to verify.
- Translate the adjectives into questions for the seller.
- Score the red flags. Owner dependence and customer concentration first.
- Run the DSCR on the real (verified) SDE before you get attached.

Frequently asked questions
SDE, seller's discretionary earnings, is the total benefit to one full-time owner-operator: net profit plus the owner's salary, interest, taxes, depreciation, and legitimate add-backs. Most small businesses are priced at a multiple of SDE, often around 2.7×.
Add-backs are expenses added back to profit to show a buyer's true earnings, owner salary, one-time costs, personal expenses. Legitimate ones are fair; aggressive or undocumented ones inflate SDE and the price, so verify every add-back in diligence.
Heavy owner dependence, customer concentration, vague or aggressive add-backs, declining revenue framed as "room to grow," urgency pressure, missing financials, and a multiple far above the norm for the industry and size.
