Most home services acquisitions that fall apart do not fail because the business was bad. They fail because of what the buyer’s due diligence team found — or did not find — in the financials. The red flags are almost always discoverable before you go to market. The question is whether you found them first.
After working on both sides of home services transactions, these are the five findings that most reliably kill deals — or reprice them so aggressively that the seller walks away.
Your business is worth more than your broker thinks.
Brokers price what’s in front of them. We find the margin leaks and owner-dependency gaps that suppress your sale price — and fix them before you list.
1. EBITDA That Does Not Reconcile to the Bank Account
This is the foundational problem and the one that creates the most damage. The seller’s P&L says EBITDA is $800K. The quality of earnings firm pulls 24 months of bank statements, totals up the deposits, subtracts the disbursements, and the resulting cash flow does not tie to the reported earnings.
In home services, this happens constantly — and it is almost always a bookkeeping problem, not a fraud problem. The contractor’s books were never set up to be reconciled to reality. Revenue is recognized when invoiced, not when collected. Payments through third-party financing platforms (GreenSky, Synchrony, Wisetack) hit the bank at different amounts and different times than what the dispatch software shows. Expenses are categorized inconsistently. Bank reconciliations were never done — or were done incorrectly.
The result: the QoE firm cannot verify the earnings the seller is claiming, which means the buyer cannot trust the purchase price they agreed to. In the best case, the deal reprices downward to whatever EBITDA the bank statements actually support. In the worst case, the buyer walks because the financial uncertainty is too high to underwrite.
Every seller should be doing their own bank reconciliation exercise — comparing deposits to reported revenue, line by line, for at least 12 months — before entering a deal process. If you cannot bridge from your P&L to your bank account, a buyer’s QoE firm will not be able to either, and that is a deal killer.
2. Owner Add-Backs That Collapse Under Scrutiny
Owner add-backs are the single most contentious element of home services deal negotiations. The seller presents adjusted EBITDA with add-backs: above-market owner compensation, personal expenses run through the business, one-time costs that the seller claims will not recur. In theory, these adjustments show what the business would earn under new ownership.
In practice, QoE firms reject add-backs aggressively — and the gap between what the seller claims and what the QoE accepts is where deals blow up.
The most common rejections we see: owner compensation add-backs where the true replacement cost is higher than the seller assumed (the seller says a replacement GM costs $100K, the market says $140K — the add-back shrinks by $40K), personal expenses that lack documentation (a truck the spouse drives, but no mileage log or proof it is personal use), and “one-time” expenses that actually recur every year (annual equipment replacements coded as one-time, recurring legal fees called non-recurring).
The danger is not that add-backs exist — every business has them. The danger is that the seller builds their asking price on add-backs they cannot defend. If you are claiming $800K in adjusted EBITDA and the QoE comes back at $550K, the deal either reprices by 30 percent or it dies. Document everything with third-party evidence, and be conservative. See our exit prep guide for how to prepare add-backs that withstand scrutiny.
3. Revenue Declining During Due Diligence
The LOI is signed based on the trailing twelve months of performance. Then two to three months pass while the buyer completes due diligence. During that period, the QoE firm is tracking current performance in real time — and if revenue or margins are softening, it raises immediate concerns.
This happens more often than sellers expect. Sometimes the owner mentally checks out after signing the LOI, spending more time thinking about life after the sale than running the business with the same intensity. Sometimes it is genuine market softness — seasonal fluctuations, a slow quarter, a lost commercial contract. Either way, a declining trend during diligence tells the buyer that the EBITDA they are paying for may not be sustainable.
Buyers respond in one of three ways: they reduce the purchase price to reflect the lower run-rate, they restructure with an earnout tied to performance targets, or they walk. None of these are what the seller wants.
The lesson: run the business as if you are keeping it until the wire hits your bank account. Do not reduce marketing spend. Do not defer maintenance. Do not coast. The trailing performance during due diligence is the freshest data the buyer has, and it carries disproportionate weight in their decision-making.
4. Key-Person Dependency with No Retention Plan
In the skilled trades, the team is the business. If two or three technicians represent 40 percent of your revenue-generating capacity and they have no employment agreements, no non-compete clauses, and no retention incentives, the buyer is looking at a business that could lose half its productive workforce the moment the sale becomes public.
Labor in the trades is extremely competitive. Experienced HVAC, plumbing, and electrical technicians are in high demand. If word gets out about an ownership change, competitors will recruit your best people — and replacing them in this labor market can take months and cost tens of thousands of dollars per technician in recruiting, training, and lost productivity.
QoE firms flag this explicitly, and buyers model technician attrition into their acquisition economics. A business with employment agreements, reasonable non-solicitation clauses, and retention bonuses that vest over 12 to 24 months post-close is worth more — because the buyer has confidence that the revenue-generating team will stay through the transition.
Get agreements in place before you enter a deal process. This is not a last-minute fix — it requires genuine conversations with your team, competitive compensation packages, and incentives that actually motivate people to stay.

5. ServiceTitan Data That Does Not Match the Books
This is the red flag unique to home services that catches sellers off guard because they did not know the problem existed. The contractor’s dispatch software — ServiceTitan, Housecall Pro, or whatever they use — tracks jobs, invoices, and payments. QuickBooks tracks the accounting. In theory, these reconcile. In practice, they almost never do.
Payments marked as collected in ServiceTitan may not have actually hit the bank account, especially when third-party financing is involved. Jobs invoiced in the field software may not appear in QuickBooks. Revenue recognized in one system does not match revenue recognized in the other. The discrepancies accumulate over months and years, and by the time a QoE firm pulls both data sets, the gaps can be material.
Two things compound this. First, the accounting basis matters: if you are keeping the books on a cash basis, they will never give a buyer a full picture of the business’s performance — revenue and costs land whenever cash moves rather than when the work is actually performed, so margins, seasonality, and true profitability are all distorted. Buyers underwrite on accrual-basis financials, so cash-basis books have to be converted before anyone can trust them. Second, when your books do not tie to ServiceTitan, you have a direct conflict between the operational KPIs and metrics the buyer is evaluating — revenue, job counts, average ticket, and margins pulled from the dispatch system — and what your actual financial statements show. If those two numbers disagree, the buyer cannot tell which one is real, and every metric in your data room comes into question.
Why this kills deals: it creates doubt about the reliability of every number the seller has presented. If the buyer cannot trust that the dispatch data and the financial data tell the same story, they cannot trust the revenue, the job margins, or the EBITDA. The financial uncertainty gets priced into the deal as a discount — or the buyer decides the risk is not worth the complexity.
Fix this before due diligence. Reconcile your dispatch software to your books monthly. Resolve third-party financing payment discrepancies. Close open invoices. Make sure the two systems tell the same story — because if they do not, a QoE firm will find the gaps, and you will pay for them in the purchase price.
