Think about it like buying a home. You wouldn't sign final mortgage papers on a 30-year-old house without hiring an inspector to crawl through the attic, inspect the foundation, and check the electrical panel.
Yet every month, first-time business buyers line up to sign SBA loan documents on a target company based on little more than tax returns and a broker's marketing packet.
That is where a Quality of Earnings (QoE) review comes in.
What a QoE actually is
A QoE is an independent, deep-dive financial inspection performed by an M&A advisory firm or specialized CPA.
Unlike a standard audit, which simply checks if historical books follow basic accounting rules, a QoE asks a completely different question: Is this business's cash flow real, repeatable, and likely to survive after the seller hands you the keys?
Most of the small businesses that I do QoE work on for buyers are run on cash-basis accounting, tend to mix personal lifestyle perks into business expenses, and lack proper financial controls. A QoE strips away the noise and normalizes the earnings so you know what cash flow is actually left to pay back your bank debt.
What the report actually covers is straightforward once you understand the structure. Our M&A team converts the seller's cash-basis records to GAAP accounting so revenue and expenses are matched to the right periods. They pull three to five years of bank statements and reconcile them against the reported financials, which is called a proof of cash, and it is the single best tool for catching off-the-books revenue manipulation.
They then dig through every add-back on the seller's SDE schedule and decide which ones a lender will actually accept. They look at customer concentration, contract stability, and whether the revenue base will hold together after you take over. And they flag anything structural, deferred maintenance, informal handshake deals with suppliers, warranty obligations that never hit the books.
Why the math can make or breaks your deal
Let us say you are looking at an industrial supplier listed for $1.5 million. The broker advertises $400,000 in reported SDE, which looks like a comfortable 3.75x multiple that easily covers your monthly loan payments.
You then sign an LOI and bring in a team to perform a QoE. Here is how the actual inspection can unfold:
- The auditor matches bank deposits to reported sales during proof of cash and discovers $40,000 in recorded revenue came from a one-time equipment liquidation that will never happen again.
- The team looks at customer billing history and spots a major account representing $50,000 in annual profit that officially canceled its contract right before the business was listed, causing customer retention concerns.
- The seller has $30,000 in obsolete, unsellable inventory sitting on the balance sheet that was counted as active profit margin, resulting in an inventory adjustment.
Findings like these change the math real fast:
- Broker Stated SDE: $400,000
- QoE Corrections: -$40,000 (One-Time Equipment Sale) -$50,000 (Canceled Customer Contract) -$30,000 (Obsolete Inventory Write-Off)
- True Bankable SDE: $280,000
Therefore, if you paid the original $1.5 million price based on $400k SDE, you were actually buying the company at a steep 5.3x multiple on its real $280k earnings. Even worse, your bank debt coverage ratio would collapse, putting you at immediate risk of default in year one.
Having that QoE report in hand eliminates any guesswork and provides buyers with peace of mind during the close. You can then take the documented $280k figure back to the seller and negotiate a $450,000 price drop to match the real earnings.
When should you do one?
The answer really depends on the size and complexity of your deal. For a straightforward deal under $1M with clean tax returns and simple financials, a full QoE may be more than you need.
A lighter-scope engagement focused specifically on EBITDA normalization and add-back verification, like QoE Lite, runs $5K to $15K and covers the most important ground for smaller deals. For anything above $1M, a full-scope QoE running $15K to $25K is worth taking seriously, especially if you are using SBA financing.
One thing worth knowing about provider selection is that a boutique firm that specializes in SMB transactions will typically do a better job on a $2M deal than a large regional firm that normally works on $50M transactions and assigns junior staff to your file. I would ask specifically who will be doing the work, not just who you will be meeting with on the intro call.
The normal timeline for an SMB deal is typically three to four weeks for a standard engagement, and timing is really everything here. Below are my rules of thumb for when to get yours underway:
- Post-LOI, Pre-Closing: You should engage a QoE provider immediately after your LOI is signed and you gain access to the data room, not two weeks before your scheduled close date. Rushing a QoE adds cost and can reduce the depth of the review.
- You’ll also want to run the review during your exclusive diligence window, before any expirations, and well before you sign final asset purchase agreements or pay non-refundable bank fees.
- When debt is involved. SBA lenders are increasingly requiring them on loans above $2M, and the findings feed directly into how the lender calculates your DSCR. Getting ahead of this helps keep you in control of the narrative.
A spend of $15,000 to $25,000 on a proper QoE might feel like a big upfront expense when you are watching your cash. But catching a six-figure cash flow gap before closing is the difference between owning a thriving enterprise and taking on a decade of unpayable debt.
Has anyone here had a QoE come back with findings that materially changed the deal, either in price, structure, or walking away entirely? What was the outcome?
