Quality of Earnings Red Flags Every Buyer Must Know

Most buyers think the income statement tells them what a business earns. It does not. It tells them what the seller reported.

Those two numbers are often very different, and the gap between them is where deals go sideways.

A quality of earnings report is how you find out which number you are actually buying. The red flags buried in that process are not always obvious. Some look like routine accounting. Others look like seller cooperation. A few look like nothing at all until the deal closes and the cash flow vanishes.

Here is what to watch for before you wire a dollar.

Revenue Red Flags That Should Stop You Cold

Revenue is the easiest place to hide problems. We have seen it enough times to know the patterns by heart.

Concentration risk. If one or two customers represent more than 30% of revenue, you have a business that can crater the moment a single relationship changes. Sellers rarely volunteer this information. You find it by pulling an aged accounts receivable report and a customer revenue breakdown. One customer at 60% of revenue is not a business. It is a contract with overhead.

One-time revenue booked as recurring. A seller lands a government contract, a litigation settlement, or a large one-off equipment sale, and it shows up in the revenue line without any disclosure. You normalize it out during QoE. If the seller resists that normalization, that tells you more than the number itself does.

Revenue pulled forward. Some businesses book revenue before the work is actually delivered. If you are looking at an accrual-basis company and receivables are growing faster than revenue, ask why. Pulled-forward revenue flatters the current period and punishes the next owner.

Related-party revenue. Revenue from entities the seller owns or controls, from family members, or from businesses with overlapping ownership. This revenue may not survive the ownership transition. Scrutinize it. And if the seller gets defensive when you ask for detail on intercompany transactions, that defensiveness is data.

What Quality of Earnings Actually Measures

A quality of earnings analysis is a deep financial review of a business’s historical cash flows. The goal is straightforward: determine whether the reported earnings are real, recurring, and sustainable.

It goes well beyond a tax return review. A QoE examines whether revenue is collectible, whether expenses are complete and normalized, and whether the earnings the seller is presenting would actually show up in your bank account after you take over. The output is an adjusted EBITDA figure (or seller’s discretionary earnings for smaller deals) that a lender and buyer can rely on.

SBA lenders require this level of confidence before they will underwrite. We will not move a deal forward without it.

For deals in the $500K to $5M range, QoE work typically happens during due diligence, either through a third-party accounting firm or through the advisory team’s own financial review. Either way, it is non-negotiable.

Expense Red Flags That Inflate Reported Earnings

On the expense side, sellers add back costs that should stay in the business. Some add-backs are legitimate. Many are not.

Owner compensation games. This is the most common issue we see. A seller pays themselves $40K and claims the market rate replacement is $50K, netting a $10K add-back. Fine. But the same seller also runs their personal car, their spouse’s salary, their health insurance, their kids’ cell phones, and two family vacations through the business. Each one gets added back. Stack them up and the SDE looks great on paper. The adjusted SDE that survives underwriting is significantly lower.

SBA lenders will allow legitimate personal expenses the new owner would not incur. They will not allow add-backs that represent real operating costs of the business. There is a line, and most sellers are on the wrong side of it.

Missing or understated expenses. A business that has not paid for outside bookkeeping, that has no marketing budget, that has not invested in equipment maintenance for 3 years. All of that suppressed spending makes margins look better. But you, as the buyer, will pay those costs. They need to stay in the model.

Deferred maintenance masquerading as profit. An owner who stopped replacing equipment, cut back on repairs, and ran the business into the ground for 2 years before listing it. The P&L looks clean. The business is not.

Rent below market. The seller owns the real estate and charges the business $3,000 per month. Market rent for the space is $6,500. That $3,500 difference is effectively hidden owner compensation. It inflates SDE and it changes completely when a third-party landlord enters the picture. Worth understanding before you get too deep into any deal where the seller also owns the building.

Working Capital Red Flags

Working capital is where experienced buyers separate from first-timers.

A business’s working capital position at close determines whether you have enough cash on hand to operate from day one. If the seller has been drawing down receivables, stretching payables, and running inventory lean heading into the sale, you are inheriting a cash flow hole.

Standard SBA deals include a working capital component in the loan. But that working capital peg is set based on historical averages. If the seller has manipulated the balance sheet in the 6 to 12 months before close, you may be underfunded before you even start.

What to look for: receivables aging that has deteriorated, payables stretched beyond normal terms, inventory levels significantly below historical averages, and deferred revenue that represents future obligations you will have to service.

Ask for monthly balance sheets going back 24 months. If the seller only provides year-end statements, that is a red flag on its own.

The Owner Reliance Problem

So the business earns $600K in SDE. The seller works 70 hours a week and is the primary sales relationship for every major client.

That is not a business. That is a job with extra steps.

Owner reliance is not always a dealbreaker. But it must be priced and structured accordingly. If the seller’s personal relationships, technical skills, or operational involvement are required to maintain the revenue, the transition risk is real and the purchase price needs to reflect it.

Things to probe: Does the owner hold the key licenses? Are customer contracts in the owner’s name? What does the team look like, and how long have key employees been there? Is there a management layer between the owner and the front-line workers?

An owner who insists the business “runs itself” but cannot produce an org chart with tenured staff is selling you on a story. Not a system.

How QoE Red Flags Affect SBA Underwriting

All of that matters. But here is where it gets practical.

Every red flag above has a direct impact on what an SBA lender will and will not accept. SBA underwriting is based on adjusted cash flow, specifically the DSCR against the proposed debt. We target a 2x DSCR. We will not move forward on a deal below 1.5x even with synergies. Deals at 1.25x (the SBA floor) are fragile and, in our experience, not worth the risk.

When QoE work reveals that add-backs are not supportable, the adjusted SDE drops. When adjusted SDE drops, the purchase price either has to come down or the deal does not pencil.

Here is a real example of how the math works. Say a seller is claiming $500K in SDE with $150K in add-backs. QoE strips out $100K of those add-backs as unsupportable. Now you are working with $400K in adjusted SDE. At the same purchase price, your DSCR may fall below 1.5x. The lender cuts the loan amount, you need more equity, or the deal dies.

This is why QoE happens before you go hard on your equity injection. Not after. The numbers you use to structure the deal have to survive scrutiny.

What Good QoE Work Actually Looks Like

A legitimate QoE process involves 3 years of tax returns, 3 years of P&L statements, monthly bank statements, aged receivables, the general ledger, payroll records, and ideally the last 12 months of bank statements to reconcile cash deposits against reported revenue. That last piece (sometimes called proof of cash) is the gold standard. If cash deposits do not tie to reported revenue, nothing else in the analysis holds up.

The advisor or accounting firm doing the QoE normalizes the financials, documents every add-back with support, and identifies adjustments the seller has not disclosed. The output is a bridge from reported earnings to adjusted earnings that a lender can underwrite against.

Good QoE work does not just confirm the seller’s number. It builds the adjusted number from scratch and lets the seller’s claims prove themselves or fall apart.

When the seller’s reported SDE and the QoE-adjusted SDE match closely, that is a green light. When they diverge significantly, you have a negotiation or an exit.

And if a seller refuses to provide the documentation needed for a proper QoE? Walk. A seller who will not support their own numbers is telling you everything you need to know.

Frequently Asked Questions

What is a quality of earnings report in a business acquisition?

A quality of earnings report is a financial analysis that examines whether a business’s reported earnings are real, recurring, and sustainable. It normalizes historical financials by removing one-time items, correcting for aggressive add-backs, and adjusting for owner-related expenses. The output is an adjusted cash flow figure that buyers and SBA lenders can rely on when structuring a deal.

How do quality of earnings red flags affect the purchase price?

Directly. If QoE work reduces the adjusted SDE, the justified purchase price at the same multiple falls with it. A seller claiming $500K in SDE that normalizes to $380K after QoE adjustments is worth meaningfully less. Buyers should use QoE findings as a negotiating tool, not just a screening tool. Price adjustments and representations and warranties in the purchase agreement often flow directly from QoE findings.

Do SBA lenders require a quality of earnings analysis?

Not always in formal terms, but they perform their own version during underwriting. SBA lenders scrutinize add-backs and require documentation for any owner expense normalization. If the lender’s adjusted cash flow does not support debt service at a 1.25x minimum DSCR, the deal reprices or does not get approved. We target 2x because deals at that SBA floor are fragile and rarely worth pursuing.

What is the most common quality of earnings red flag in small business acquisitions?

Unsupportable add-backs to owner compensation. We see it across nearly every deal in the $500K to $5M range. Sellers routinely overstate how much of their personal lifestyle runs through the business. When a lender’s underwriter reviews the actual documentation, a significant portion of those add-backs gets rejected, compressing the adjusted SDE and often killing the deal at the original price.

When should quality of earnings work happen in the acquisition process?

Before you go hard on your equity injection or remove major contingencies. Ideally, basic financial review happens before you submit your LOI. Full QoE work happens during the due diligence window after the LOI is accepted, with the purchase price and structure subject to adjustment based on findings. Waiting until late diligence to discover major discrepancies is how buyers lose time, money, and credibility with lenders.
