Buyers check nine things before they write an offer on your business: trailing 12-month EBITDA and SDE, customer concentration, revenue trend, owner dependency, recurring revenue, worker classification, accounts receivable aging, contract transferability, and tax-to-P&L alignment. According to Axial's Dead Deal Analysis, Miss two or three of these and you don't get a lower offer. You get no offer, or a signed LOI that dies in diligence. Fix all nine in the 90 days before you go to market and you walk into the room with use instead of hope.

I've reviewed hundreds of deal packages through AIN. The ones that fall apart at LOI always fail on the same 3-4 hygiene items. It's never the revenue story. It's the books.

The LOI Is Not the Finish Line. It's the Test.

Owners treat a signed letter of intent like a closed deal. It isn't. Axial's Dead Deal Report on 2025 transactions found that non-QoE diligence findings caused 25.3% of broken LOIs, and quality-of-earnings EBITDA discrepancies caused another 21.3%. Add those together and you get 46.6%. Nearly half of every dead deal died because the buyer looked closely and didn't like what they found. Financing problems, the thing owners fear most, caused only 10.7%.

The math repeats in deal after deal. A buyer who agrees to 5x a claimed $2M EBITDA is offering $10M. If quality-of-earnings work finds the real, defensible number is $1.6M, the same 5x multiple now supports $8M. That's a $2M haircut on one clean discrepancy. The buyer isn't punishing you. They're correcting the deal to reflect reality.

CT Acquisitions puts it plainly: exit readiness is a program, not a scramble. Prepared firms sell for 12-17% higher multiples than firms that scramble to assemble a data room after a buyer shows interest. And a 2026 ACG survey found buyers exercising "extreme discipline" this year. Multiples for A-grade targets are insanely high. Lower-grade companies are not getting bids at all. There is no middle anymore. You're either the business that gets fought over or the business that gets ignored.

That's why I built The 90-Day Bottleneck Audit. It's the fastest path to closing the nine gaps that kill deals before an offer gets written, done in the three months before you go to market.

The 90-Day Bottleneck Audit: 9 Items Buyers Check Before an Offer

Work through these in order. Each one takes two to six weeks to fix properly, and several can run in parallel.

1. Trailing 12-Month EBITDA and SDE, With Documented Add-Backs

What it is. Your normalized earnings number, built from net income plus interest, taxes, depreciation, amortization, and owner-specific add-backs like above-market salary, personal vehicle expenses, and one-time legal costs.

Why buyers care. Every dollar of accepted add-back increases your sale price by your multiple. Every dollar of rejected add-back does the opposite. A buyer's quality-of-earnings analyst treats every claimed add-back as an audit finding waiting to get tested, not a number to take on faith.

How to fix it in 90 days. Build an add-back schedule with a paper trail for each line: canceled checks, invoices, W-2s, contracts, calendar entries. Sellers with full documentation typically retain 85-95% of claimed add-backs through QoE. Sellers with none lose 30-50%. On a $2M-$5M deal, that gap is worth $200K-$800K. Cap your total add-back load below 25-30% of reported EBITDA. Above that, buyers assume the books are dirty even if every line is legitimate.

2. Customer Concentration

What it is. The percentage of your annual revenue that comes from your single largest customer, and from your top five combined.

Why buyers care. Above 20% from one customer, buyers start modeling what happens to your cash flow if that account leaves the week after closing. Concentration in the 25-40% range typically cuts sale price 10-20%. Above 40%, the discount runs 20-30% or more, and many SBA lenders won't finance the deal at all. Businesses under 10% concentration trade at roughly 5.4x EBITDA in the lower middle market. That multiple compresses to around 3.1x once a single customer hits 40-50% of revenue, a 43% swing on the same underlying earnings.

How to fix it in 90 days. You can't manufacture new customers in three months, but you can lock the risk down. Get a multi-year contract with defined renewal terms on any account above 20%. Document tenure, retention history, and whether the relationship touches your management team, not just you. A 12-month termination notice cuts the discount from 20-30% down to 5-10%, because it gives a buyer a protected runway even if the customer eventually leaves.

3. Revenue Trend: Three-Year Growth vs. Flat vs. Decline

What it is. Your top-line trajectory over the trailing three years, not just the most recent 12 months.

Why buyers care. A single strong year on top of two flat or declining years reads as an anomaly, not a trend, and buyers price anomalies at a discount. They want evidence the business is compounding, not a lucky quarter.

How to fix it in 90 days. You won't rewrite three years of history. You can build the bridge that explains the trend, month by month, with specific drivers, so a buyer sees a business they understand instead of a number they're suspicious of. If growth stalled for a clear reason, one lost customer, one bad hire, document it and show the recovery already underway.

4. Owner Dependency Score

What it is. How much of the business runs through you personally: hours worked per week, key vendor and customer relationships, sole signing authority, undocumented processes that live in your head.

Why buyers care. Buyers aren't just acquiring your financial performance. They're acquiring a system. If every pricing decision, every key relationship, and every employee issue routes through the owner, the buyer sees a job, not a business. This typically shows up as a longer required transition period, a bigger earnout, or a lower multiple entirely.

How to fix it in 90 days. Delegate signing authority on routine purchases and vendor approvals. Write down your top five customer and vendor relationships and introduce a second point of contact for each. Document your three most owner-dependent processes as step-by-step SOPs. This is the highest-use project on this list, because owner dependency touches every other item on this audit.

5. Recurring Revenue Percentage

What it is. The share of total revenue that comes from contracts, subscriptions, retainers, or service agreements, as opposed to one-off project or transactional work.

Why buyers care. Recurring revenue is easier to underwrite, easier to finance, and commands a materially higher multiple than lumpy project revenue, because it's more likely to still be there in year two under new ownership.

How to fix it in 90 days. Convert your best transactional customers to service agreements or retainers wherever the relationship supports it. Even a 12-month agreement with auto-renewal changes how a buyer classifies that revenue. Move recurring revenue up before you go to market, not after.

6. Employee and Contractor Classification (1099 vs. W-2)

What it is. Whether the people doing recurring, controlled work for your business are correctly classified as employees or independent contractors under federal and state tests.

Why buyers care. Misclassification liability transfers to the buyer at close. Acquirers calculate it as a range, typically 15-30% of a contractor's annual compensation per year of engagement in back taxes and penalties, and either deduct the midpoint from price or hold it back in escrow. For five contractors at $60K each over two years, that's a $90K-$360K swing.

How to fix it in 90 days. Run a classification review on every 1099 worker who looks like an employee: fixed hours, single client, company equipment, day-to-day integration into your team. Reclassify where the facts require it, or restructure the engagement so it clearly satisfies your state's test. Document the analysis even for workers you keep as contractors. Buyers don't need proof you're clean. They need evidence you checked.

7. Accounts Receivable Aging

What it is. The breakdown of what customers owe you by how long the invoice has been outstanding: current, 30 days, 60 days, 90-plus days.

Why buyers care. A founder sees receivables as money that belongs to the company. A buyer sees aged receivables as risk they might never collect. Once a meaningful share of AR crosses 60 days, many buyers discount it sharply or exclude it entirely from the working capital target, which comes straight out of your proceeds at close.

How to fix it in 90 days. Run an aging report today. Call every account over 45 days personally. Tighten payment terms on new invoices and enforce them. Write off or reserve against anything genuinely uncollectible rather than letting it inflate a number a buyer will strike anyway. A clean, current AR ledger at close is worth more to you than a bloated one you have to defend.

8. Lease and Contract Transferability

What it is. Whether your facility lease, equipment financing, and key vendor and customer contracts can legally transfer to a new owner, and on what terms.

Why buyers care. A change-of-control clause that requires landlord or vendor consent, or that triggers a termination right, can blow up a deal in the final weeks even after price and terms are agreed. Buyers don't want to discover an assignment problem during exclusivity. They want to see it's already solved.

How to fix it in 90 days. Pull every lease and material contract and read the assignment and change-of-control language specifically. Where consent is required, start the conversation with the landlord or vendor now, quietly, before a buyer's attorney forces the issue on a deadline. A pre-cleared assignment path removes a variable that otherwise sits in the buyer's favor during the final negotiation.

9. Tax Return Alignment With P&L

What it is. Whether your reported revenue and expenses on your tax returns match what your internal profit and loss statements show, for at least the trailing three years.

Why buyers care. This is the trust killer above all others. A buyer's CPA will reconcile your tax returns against your P&L as one of the first steps in diligence. A discrepancy doesn't just raise a question about that one number. It raises a question about every number you've presented, and confidence, once shaken, doesn't come back easily.

How to fix it in 90 days. Reconcile your last three years of tax returns against your internal financials line by line. Where they diverge, whether from aggressive tax positions, timing differences, or informal bookkeeping, document the reason in writing before a buyer asks. If you find real gaps you can't explain, get your CPA involved now. A discrepancy you disclose and explain is a footnote. A discrepancy the buyer finds on their own is a reason to walk.

Why 90 Days Beats a Scramble

None of these nine items requires a year of preparation. They require focus and a deadline. Exit readiness is a program, not a scramble, and prepared firms sell for 12-17% higher multiples than firms that try to assemble this after a term sheet is already on the table. Health is a financial asset. A business with clean books, contained owner dependency, and defensible numbers isn't just easier to sell. It's worth more, because the buyer isn't pricing in the risk of what they haven't found yet.

Run this audit even if you're not selling for two years. The habits it builds, monthly reconciliation, documented add-backs, a real AR process, make the business easier to run, too.

FAQ

How long before a sale should I start pre-LOI financial hygiene work? Start the full 90-Day Bottleneck Audit at minimum 90 days before you plan to go to market, and ideally 6-12 months out if your books have real gaps, undocumented add-backs, or unreconciled accounts. Owner dependency and customer concentration take longer to move than the other seven items.

What's the single item most likely to kill my deal? EBITDA discrepancies from quality-of-earnings review and non-QoE diligence findings together account for close to half of all broken LOIs. Undocumented add-backs and tax-to-P&L mismatches are the two issues inside that category that surface most often and destroy buyer trust fastest.

Do I need a formal quality-of-earnings review before going to market? If your enterprise value is above roughly $2M, yes. A sell-side QoE, run on your own timeline before a buyer's QoE finds the same issues mid-exclusivity, costs $20K-$40K and routinely pays for itself by catching what would otherwise trigger a retrade.

What customer concentration level should worry me? Any single customer above 20% of revenue gets flagged in a serious buyer's process. Above 40%, expect a 20-30% price discount or a deal structure that shifts risk back onto you through an earnout or escrow. Below 15% is the safe zone most advisors target.

Can I fix owner dependency in just 90 days? You can't eliminate it, but you can reduce it: delegate signing authority, introduce a second contact on your top relationships, and document your most critical processes. Buyers reward visible progress here even when it isn't finished, because it shows the business can survive a transition.
