There is a version of this conversation that starts with the listing price. That is the wrong version.
The version that matters starts with whether the earnings behind that price are real. On a sub-$1M acquisition, a quality of earnings analysis is the thing standing between you and a business that looked profitable in the broker’s package but generates $60K less cash than the seller claimed. And at this deal size, $60K is not a rounding error. It is the difference between a deal that works and one that quietly drowns you in Year 2.
Here is what quality of earnings for business under $1 million actually involves, why most buyers underestimate it, and where the real risk hides in the numbers.
What Quality of Earnings Actually Means
Quality of earnings (QoE) refers to how reliable, recurring, and accurately represented a business’s cash flow is. Not just whether the revenue number is real. Whether that revenue will still be there six months after you take over.
For a business under $1M in acquisition price, you are almost certainly looking at seller discretionary earnings (SDE) as the starting metric. But here is the thing buyers need to understand early: SDE is a broker-friendly number. It is designed to make a business look as attractive as possible. From what we have seen across hundreds of deals, the real cash flow after proper normalization runs 15% to 50% below the stated SDE. That gap is not a minor footnote. It changes whether the deal makes sense at all.
Quality of earnings analysis at this level means interrogating every line of that SDE calculation, starting from the assumption that the number is inflated until you can prove otherwise.
Why Sub-$1M Deals Carry Specific QoE Risks
Businesses at this size are almost always owner-operated. The financials reflect that in ways that matter.
Most sellers here are not running GAAP-compliant books with a CFO reviewing monthly closes. They are running QuickBooks with a part-time bookkeeper, sometimes a spouse, occasionally nothing but a spreadsheet and a shoebox of receipts they hand their CPA in February. That creates a set of risks you will not encounter in a $5M deal with audited financials.
Personal expenses run through the business. This is not always intentional fraud. Plenty of sellers genuinely blur the line between business and personal. Cell phone, vehicle, health insurance, a trip to Vegas that was technically a “conference.” These all get added back in the SDE calculation. The question is whether the add-backs are clean.
Revenue recognition problems. A service business that invoices on completion may have 60 days of work-in-progress sitting off the books. A subscription business may be recording multi-year contracts as current-year revenue. This matters for what you inherit.
Related-party transactions. The seller rents the business its operating space from an LLC he also owns. The rent is $2,500 per month and the market rate is $4,200. That $20,400 annual delta affects your actual cost basis post-close. It will not show up in the SDE add-backs unless someone looks.
Key person revenue. For businesses under $1M, a disproportionate share of revenue often traces back to relationships the seller built over 15 years. When those relationships follow the seller out the door, the $180K in SDE you underwrote quietly becomes $110K. You would be surprised how many deals die right here.
How QoE Analysis Works at This Deal Size
You are not hiring a Big 4 firm to deliver a 90-page report on a $750K bakery acquisition. That is not the right tool for the job.
What you are doing is a structured review of 3 years of financials with specific goals:
Normalize the SDE. Start with the seller’s stated SDE and work backwards. Every add-back needs documentation. Owner salary add-back: see the W-2. Personal vehicle add-back: see what portion is actually business use. One-time legal expense add-back: read the invoice and confirm it does not recur. If you cannot document it, it does not count.
Verify revenue quality. Pull the accounts receivable aging. Look at customer concentration. If the top three customers represent 70% of revenue, that is a concentration risk your lender will flag anyway, but you need to understand the exposure before you are deep into closing.
Trace cash flow to the bank. Get three years of bank statements alongside the tax returns. Revenue reported on the P&L should reconcile with deposits. If the P&L shows $800K in revenue and the bank shows $640K in deposits with no clear explanation for the gap, that is not an accounting timing issue. That is a problem. Walk.
Identify capital expenditure patterns. Small business owners often defer maintenance and equipment replacement to make the numbers look better in a sale year (and sometimes for several years before that). If you are buying a commercial cleaning company and the owner has not replaced equipment in 6 years, the SDE looks clean but your first 18 months of ownership includes a replacement cycle the seller’s numbers do not reflect.
This work typically takes 20 to 40 hours for a small business. For a competent CPA or M&A advisor who does this regularly, the cost runs somewhere between $3,000 and $8,000 depending on complexity. On a $900K deal financed with SBA, that is a rounding error compared to what you lose if the earnings are wrong.
The SBA Lender’s Version of Earnings Verification
All of that matters, but here is the part most buyers skip.
If you are using an SBA 7(a) loan to finance the acquisition (which you should be, at this deal size), the lender runs their own version of earnings verification. They pull the last 3 years of business tax returns and compare them to the broker’s financial presentation. They build a DSCR model.
Now, the lender’s standard threshold is a 1.25x DSCR. That is the bank’s minimum, not yours. A 1.25x DSCR means if the business produces even slightly less than projected, you are underwater on debt service with zero margin. We target a 2x DSCR on our deals. The floor we work with is 1.5x. Anything below 1.5x and the deal needs serious restructuring or you need to walk away.
But here is what buyers miss: the lender’s QoE analysis is not designed to protect you. It is designed to protect the bank. The lender might approve a deal where the seller’s add-backs are aggressive because the base revenue still covers debt service at their minimum threshold. You, as the buyer, are the one who has to operate the business when those add-backs turn out to be wrong.
Do not treat the lender’s underwriting as a substitute for your own diligence. They are answering a different question than you are.
The Seller Note Connection
On most SBA deals for businesses under $1M, a seller note is part of the deal structure. The seller carries back a portion of the purchase price, and this is actually a quality of earnings signal in its own right.
A seller who refuses to carry any note, or who wants the note paid off in 12 to 18 months, is telling you something about their confidence in the forward earnings. Read that signal carefully.
A seller who agrees to a 10-year standby note at 0% interest (which is the structure we achieve on roughly 90% of our deals) has meaningful skin in the game. If the earnings they represented do not materialize, the note is still outstanding. That alignment matters more than most buyers realize.
If the seller is not willing to carry a note, ask why. The answer is informative.
What a Real Red Flag Looks Like in the Numbers
Here is a scenario that shows up in the sub-$1M market more than it should.
A $650K landscaping business. The broker’s financial summary shows $195K in SDE. The seller is asking 3.3x, so roughly $643K. On its face, the SDE multiple is reasonable for a stable service business.
You dig into the add-backs. Owner salary: $85K, clean. Personal vehicle: $14K. Cell phones for owner and spouse: $4,800. Health insurance: $12K. One-time equipment repair: $22,000.
That last one.
You pull the invoice. It is for a commercial mower fleet overhaul. You check the prior year. Similar line item, $18,000. Year before that, $24,000.
That is not a one-time add-back. That is a recurring capital maintenance cost that the seller has been normalizing out of the SDE calculation for three straight years. And this is exactly why we say SDE is unreliable as stated. The broker’s number assumed that $22K was an anomaly. It was not.
Real SDE is closer to $150K to $155K. At that corrected number, the deal does not clear a 1.5x DSCR at the asking price (it barely clears the bank’s 1.25x minimum, which gives you essentially no margin for anything to go wrong). You either negotiate the price down significantly, restructure the terms, or you walk.
This is quality of earnings work. Not exotic. Just methodical.
Quality of Earnings for Business Under $1 Million: Where to Start
If you are under LOI on a sub-$1M deal, or approaching that stage, here is how to begin.
Request the last 3 years of tax returns (business and personal if it is a sole proprietorship or single-member LLC) alongside the last 3 years of bank statements and a current accounts receivable aging report. Three years of tax returns. Minimum.
Then build your own SDE model from the tax returns. Do not start from the broker’s number. Start from gross revenue on the return and work down. The delta between your number and the broker’s number tells you where to focus your diligence questions. If the gap is small, good. If it is 20% or more, you have found where the add-back games are hiding.
Side note: this is also where proof of cash matters. If the bank statements do not reconcile with the tax returns, none of the analysis above holds up. Proof of cash is the gold standard for a reason. If it does not tie, walk.
Third, get a CPA with small business acquisition experience involved before you make any major decisions. Not a generalist. Someone who has reviewed acquisition financials at this deal size and knows what the risk looks like in the books of a $700K service business.
If you are working with an acquisition advisor, this process should be embedded in their diligence workflow. If it is not, that is worth knowing before you hand them a retainer.
Frequently Asked Questions
Do I really need a formal quality of earnings report for a business under $1 million?
A formal third-party QoE report is not always necessary at this deal size, but the analysis behind one is non-negotiable. You need to verify every add-back, reconcile P&L to bank statements, and assess customer concentration before you close. Whether that work comes from your CPA, your acquisition advisor, or a boutique diligence firm depends on deal complexity and your budget.
How does quality of earnings affect my SBA loan approval?
SBA lenders run their own earnings verification using 3 years of tax returns. If your deal’s SDE relies heavily on add-backs that do not appear in the returns, the lender may use a lower earnings figure for underwriting. That directly affects the loan amount and whether the deal hits minimum DSCR requirements. Clean, documentable add-backs get better treatment than aggressive ones.
What is the most common quality of earnings problem in sub-$1M deals?
Recurring costs misclassified as one-time add-backs. Equipment maintenance, owner-initiated legal disputes, and irregular marketing spend get added back to SDE constantly. Buyers accept the add-back without checking whether similar expenses appeared in prior years. When they do, the real SDE is materially lower than the broker’s presentation shows.
How does a seller note relate to quality of earnings?
A seller note creates alignment between what the seller claims the business earns and what it actually produces post-close. If the earnings were overstated and the business underperforms, the seller still has an outstanding note. That skin-in-the-game dynamic is why buyers with a well-structured seller note have downside protection that all-cash deals lack. We target a 10-year, 0% interest standby note on most deals.
Can I do quality of earnings analysis myself?
You can do a meaningful portion of it, particularly if you have a financial background. Start with the tax returns versus P&L reconciliation and the add-back documentation review. For anything involving inventory valuation, deferred revenue, or related-party transactions, bring in a CPA. The cost of professional review on a $600K to $900K deal is almost always less than the cost of overpaying by 10% to 15%.
