Buy-Side AdvisoryA deal you close on verified numbers, not on the seller's story.

End-to-end buy-side advisory: synergy modeling, Quality of Earnings, operational and commercial diligence, SPA risk allocation, price-chip negotiation. Each finding turns into either a price chip or a walk-away, before the wire goes out.

What the Story Leaves Out

Information asymmetry

You've seen the Confidential Information Memorandum. You've heard the founder's story. It sounds like a goldmine.

But in M&A, the difference between a successful acquisition and a million-dollar mistake usually comes down to what wasn't said: whether the revenue is sticky, whether the team is staying, whether the "synergies" are real or just math on a slide.

When Projections Meet the First Quarter

Capital at risk

Growth through acquisition puts real capital and your reputation on someone else's data. The challenge is making sure the asset performs the way you projected once the deal closes.

One overlooked tax liability or an aging tech stack can erase years of expected profits.

Buying More Than a Balance Sheet

Information parity

You're buying a culture, a customer list, and a set of processes, and the seller knows all three better than you do.

Finding the target is only the beginning; the real work is closing that information gap before you price the deal. That gap is exactly what I close.

No strings attached

Send me the seller's CIM, model, or financials. I review the assumptions, structure, and outputs, and reply with the three findings that matter most before you submit an offer.

Reply within one business day.
No automated funnel.

The seller has run this business for years. You have a CIM and a few weeks. I verify the revenue, recompute the margins, and test every assumption the seller has presented as fact.

While you focus on strategy and cultural fit, my work goes into the inner workings of the business. My job is to give you the confidence to walk away from a bad deal, or the evidence to negotiate a better price based on hard data, not the founder's narrative.

The best entry prices are where other buyers aren't

Auction processes with five bidders produce full prices. The better economics sit in three places most buyers avoid, because each one demands work they can't do in-house. That work is exactly what I do.

Distressed and special situations

Motivated sellers

Insolvency sales, restructurings, carve-outs from groups under pressure. The price reflects the seller's situation, not the asset's quality, and that spread is the opportunity.

These deals reward speed, hard verification, and risk allocation in the SPA. I separate the businesses that are cheap for a reason from the ones that are cheap because the seller ran out of time.

Assets below replacement cost

The replacement cost test

The oldest test in value investing: what would it cost to build this capacity from zero today? When you can buy equipment, facilities, contracts or an installed customer base for less than it costs to recreate them, the downside has a floor.

I run the replacement cost math next to the earnings math, and the deal only proceeds when both support the price.

Off-market and low-competition deals

Proprietary deal flow

Owners approaching retirement without a banker, businesses that never reach a listing, sectors too small for the funds to bother with. Fewer bidders means better entry prices and saner terms.

I run direct, confidential outreach to targets that fit your criteria, so you negotiate one-on-one instead of bidding against a room.

Five phases, no surprises after the wire goes out

Five phases, signed off step by step, so you watch the diligence take shape and never receive a black box at close. Some phases are pure investigative work and stay on my desk; others need you in the room, your lawyer at the table, or the seller's team across it. When a step needs a skill outside mine, sector benchmarks, tax structuring, environmental review, I bring in a specialist I have worked with before instead of improvising.

1

Preliminary review, synergy modeling, NBO

Target analysis & deal architecture

The seller's data gets screened for early red flags, then the target modeled against your existing financials to validate that the synergies are real and not just math on a slide. From there I frame a non-binding offer with terms that protect your right to adjust as findings emerge: a clean entry that signals you are a serious, sophisticated buyer.

2

QofE, operational, commercial, legal review

Quality of Earnings & due diligence

One-time gains and accounting noise get stripped from the financials to expose the true recurring cash flow under your ownership. Customer concentration, contract stability, middle-management strength, IP ownership, employment disputes, and regulatory exposure all get reviewed: every risk that does not show up on a balance sheet.

3

Payment terms, earn-outs, SPA risk allocation

Transaction structuring

I design how you actually pay: balancing cash at closing with deferred payments, earn-out KPIs tied to verifiable performance, and indemnities, holdbacks, or escrow accounts in the SPA. The structure incentivizes the founder to deliver on promises and shifts the risk of anything I found in diligence back onto the seller.

4

Price chip, conditions precedent, fund transfer

Final negotiation & closing

Findings get converted into negotiation leverage: a price chip where the diligence exposed a gap, tightened earn-out thresholds where the projections looked stretched. I oversee the final signing and verify every condition precedent has been met before a single dollar moves. You become the owner of a verified asset.

5

Earn-out tracking, KPI verification

Post-closing monitoring

If the deal includes an earn-out, the work continues. I monitor the agreed indicators against the targets set in structuring, so future payments reflect the actual performance of the asset, not the spreadsheet projection that existed only in the seller's pitch deck.

Share the seller's CIM, model, or financial pack. I review the assumptions, structure, and outputs, and reply with the three findings that matter most before you submit an offer.

Questions I get on every first call

Deal size, QofE, distressed acquisitions, walk-aways and pricing come up almost every time. Short answers below, longer answers on the call.

Do I need a buy-side advisor for a small acquisition?

The smaller the deal, the bigger the mistake is relative to your capital. A $2M acquisition with an undisclosed customer-concentration problem hurts a private buyer far more than a $200M deal hurts a fund. The diligence scales down; the need for it does not.

What is a Quality of Earnings report and do I need one?

A QofE strips one-time gains, owner adjustments and accounting noise out of the seller's numbers to show the real recurring cash flow you would own. If the price is based on EBITDA, and it almost always is, then the QofE is the document that tells you whether that EBITDA exists. Lenders increasingly require one.

Can you help with distressed or insolvency acquisitions?

Yes, and they are a focus. Distressed deals compress the timeline and shift the work toward fast verification and SPA risk allocation. I help you confirm what you are buying, price the risks you are inheriting, and structure protections for the ones you cannot eliminate.

What happens if you find a deal-breaker?

You walk away, and that is a successful engagement. The retainer bought you the protection. Roughly speaking, the most profitable deals I have worked on are some of the ones my clients never closed.

How do you charge?

A retainer covers the diligence work, sized to the complexity of the target. A success fee is paid only at closing, with the retainer credited in full against it. You pay for the result, not for the time.
