Deal Diligence · Sell-Side & Buy-Side
Quality of Earnings done by operators.
Every deal hangs on two questions: are the earnings real, and do they survive the handoff? LIMESTONE answers both. On the sell side, know your number before a buyer prices it for you. On the buy side, know what you're buying before you wire. Operator-grade, independent, and built for lower-middle-market deals, roughly $500K to $5M of EBITDA.

Diligence is the most common place a signed deal dies.

Quality of earnings reviews
Ryan, a CPA, has run more than a hundred of these, buy-side and sell-side. Whatever a buyer's reviewer will do to your numbers, he's already done it to someone else's.

Signed LOIs never close
Diligence findings are the leading cause. The deals that close are the ones whose numbers were proven before anyone tested them.
~90% vs ~50%
Who gets a sell-side QoE
Around 90% of PE-backed sellers commission one before going to market. Barely half of founder-led sellers do. The prepared negotiate against the unprepared, and it shows up in the price.

Why Operators
The report and the exhibit book prove what happened. We also advise on what to do next.
Most reviews at this deal size come back as a checklist. A buyer reads one and still doesn't know if the earnings are real, or what to do if they aren't. LIMESTONE goes further, because we have run businesses ourselves: we can tell you which problems are fixable, which ones move the price, and which ones kill the deal.
The add-back we strike most often is not the country club or the truck. It is the one-time consulting fee that turns up in all three years. Nobody is lying; they just never had a reason to look.
That's the pairing you hire. The CPA who has been the buyer's reviewer, and the operator who carried a company through a $200M sale. The numbers, proven. The judgment on whether they hold. One without the other is half an answer.
The Buyer’s-Eye Read
What a buyer actually checks, and what we find first.
Proof of cash
LIMESTONE ties every dollar you claim you made to the bank account. Bank statements are the hardest thing in a deal to dress up, and the proof of cash is the first test a serious buyer runs.
The add-back test: real, provable, defensible
Every add-back has to clear three gates. Real: it isn't a true go-forward cost, it's non-recurring, personal, or restated to a market rate. Provable: a statement or contract backs it. Defensible: you can explain it to a skeptical buyer out loud. Fail one, it comes off. No source, no add-back.
Revenue quality & concentration
Recurring versus one-off, and who your top customers really are. Concentration is one of the first things a buyer discounts for, and a lender may flag a single customer over 15 to 20%.
Net working capital peg
The quiet deal-killer, and the gas you're expected to leave in the tank at close. LIMESTONE sets and defends the peg before you sign, so the true-up ninety days later lands as arithmetic, not as a surprise.
WHAT IT COVERS
What a QoE answers, and what it doesn’t.

IF YOU'RE BUYING
Everything you know about this business came from the person selling it.
The memo, the add-back schedule, the explanation for why last year was soft: all of it was assembled by someone with a reason to make it look good. That's not an accusation, it's the structure of the transaction. LIMESTONE reads the numbers the way a skeptical lender would, and we tell you what we find while there's still time to use it: what's real, what's padded, what working capital will actually cost you on day one, and whether the earnings walk out the door with the owner. If a lender is relying on the report, we build it to that standard.
And if you're buying with an SBA loan, you're guaranteeing that debt personally. That makes this the cheapest protection in the whole deal.

IF YOU'RE SELLING
Run the exam on yourself before the buyer does.
A sell-side review is the trial run for the buyer's diligence. LIMESTONE stages your data room, pressure-tests the numbers, and surfaces what a buyer would flag while there's still time to fix it and while the cards are still in your hand. The two deal-killers are time and surprise, and both are removable. A document you can turn around in a day signals a real business. Weeks signals something else.

THE SECOND QUESTION
The seller's numbers are history. Whether they hold for a new owner is a different question.
Where a financial scope stops, ours can keep going: owner dependency, concentration tested rather than tabulated, bench depth, and on buy-side deals, where the seller allows contact, reference calls to the customers themselves. Where they don't, that restriction is itself a finding. The Quality of Earnings answers the first question, are the earnings real. This answers the second, do they survive the handoff.

How We Quote
One number, before you commit. No meter.
LIMESTONE scopes on a short call and comes back with one fixed fee, usually within a business day. It goes in writing before work starts and does not move unless you ask. Anything outside it is priced and approved first, never absorbed quietly.
On a deal this size we will usually come in under a national or large regional firm, and the partners who scope the work are the ones who do it.
Not ready for a full review? Plenty of what we see does not need one: an offer on the table, a CIM you are reading, a straight answer on whether a deal is worth chasing. Tell us the question and we will quote one number.
What You Receive
The Report. The written conclusion, section by section, in prose. It states what we found and what it means, and it is the only one that carries our conclusions.
The Exhibit Book. The evidence: an executive dashboard, then one exhibit per page in the same order as the report. Every page names the tab in the workbook its figures came from.
The Workbook. The cleaned Excel file the whole package is built from, so you or your advisor can audit any number back to its source.
How We Communicate
You will never wonder where this stands.
A written update every week, and a call whenever it needs one. You see the draft before anyone else does. We call you the day before the readout, so nothing in it is a surprise. If the findings move the price, you get one clean recommendation, not a series of haircuts.
How We Use AI
The systems do the retyping. The judgment is ours.
AI takes the repetition out of the routine work, and Crunchafi lands three years of a target's ledger standardized in days rather than a week of re-keying. That time goes into the analysis and the calls. The opinion stays human, and you own your data.
Scope
Most deals at this size land on Core.
