🔬 360° pre-close acquisition audit — financials, operations, legal & risk

You don’t just need
to verify the numbers.
You need to audit
the whole deal.

A P&L review catches financial fraud. A full acquisition audit catches everything else — the operational liabilities, the legal exposure, the key-man dependencies, and the customer risks that destroy businesses in the first 90 days after close.

How it’s different

A P&L review is not an acquisition audit.

Financial verification tells you whether the seller’s earnings are real. A full acquisition audit tells you whether the business you’re buying is actually transferable, defensible, and sustainable under new ownership.

The acquisitions that destroy first-time buyers are rarely financial frauds. They are businesses where the customer left with the owner, the staff quit within 90 days, the key contract wasn’t assignable, or the equipment needed $200K in replacement the month after close.

The full audit catches all of it. Before you sign.

What we find

The risks that destroy acquisitions — and how we score them

Every finding in the audit is scored by severity: High, Medium, or Low. High-severity findings have specific dollar amounts attached. You walk into renegotiation knowing exactly what each issue costs.

High-severity risks (price-adjusting)
⚠️

Unverified add-backs

Add-backs without primary source documentation are rejected by buyers

High
⚠️

Customer concentration over 25%

Single customer above 25% of revenue on month-to-month terms

High
⚠️

Non-assignable contracts

Customer or vendor contracts that require consent to transfer

High
⚠️

Undisclosed deferred maintenance

Equipment or facilities requiring capital expenditure within 90 days

High
⚠️

Revenue timing manipulation

Billing pulled forward into the sale period to inflate TTM revenue

High
Medium & lower severity risks
📋

Missing SOP documentation

Core processes undocumented — increases integration risk and timeline

Medium
👤

Owner key-man dependency

Defined functions only owner can perform without a documented backup

Medium
📄

Licenses in owner’s personal name

Permits that require re-application under new ownership

Medium
💼

Below-market staff compensation

Key employees paid below market — retention risk post-close

Lower
🏢

Lease term under 18 months remaining

Short lease term without renewal option reduces buyer confidence

Lower
Every High-severity finding is documented with a specific price adjustment recommendation at your agreed multiple. You never negotiate with a vague concern — you negotiate with a number.
Heather Griffith Barber
About Heather

I built the 5-pillar framework because a P&L review was never enough.

Heather Griffith Barber has spent her career at the intersection of acquisition strategy and financial verification. She built Utah’s largest vehicle wrap company from scratch at 23 and spent the years that followed helping buyers and sellers navigate the information asymmetry that defines small business M&A.

She is the author of The Due Diligence Bible — the 220-page framework that forms the foundation of the 87-checkpoint Audit My Acquisition methodology — and the creator of the Buy Scale Sell valuation platform used by 900+ acquisition professionals.

The 5-pillar audit was built because she watched buyers get destroyed by risks that a financial review would never have caught: the 40% customer who left with the owner, the lease that expired at month 4, the key technician who quit on day 31.

What a full audit found that a P&L review would have missed.

First acquisition — HVAC business

“The financial review found $89K in bad add-backs. Fine. But the operational audit found that the owner personally managed all 14 key accounts. The human capital pillar scored it as a high-severity key-man risk. We renegotiated $340K off the price and added a 12-month earnout. That finding alone was worth 36x the audit fee.”

JM
James M.
Dallas, TX
$340K renegotiated from operational finding
Rollup operator — third acquisition

“The legal pillar found that the top-revenue customer contract had a change-of-control clause. The seller had never mentioned it. That single clause would have let the customer walk away at close — 38% of revenue gone on day one. The audit saved the deal by forcing a contract renegotiation before close.”

SK
Sarah K.
Chicago, IL
38% revenue risk identified and mitigated
ETA searcher — pest control acquisition

“The equipment audit found the fleet needed $180K in replacement within 18 months. None of it was in the P&L. The deferred maintenance score was high-severity. We adjusted the purchase price down $180K dollar-for-dollar. The $9,500 audit paid back 19x before we even closed.”

Common questions

What buyers ask before they start an audit.

How is this different from EarningsVerified.com?
EarningsVerified is a fast, financial-focused verification service — ideal for buyers who need a P&L scrub and QoE report quickly. Audit My Acquisition is the comprehensive 5-pillar acquisition audit covering financials, operations, legal, human capital, and market risk. For deals above $795K, you want the full audit. For a fast red-flag check, EarningsVerified is the right starting point.
What deal size warrants a full acquisition audit?
We recommend the full 87-checkpoint audit for any deal above $500K. Below that, the $795 Red Flag Diagnostic Call call is usually sufficient for a first pass. The full audit is most valuable for deals in the $795K–$5M range where the operational, legal, and human capital risks are material and the purchase price impact of any finding is significant.
What documents do I need to start the audit?
At minimum: 3 years of P&Ls and tax returns, the signed LOI, a customer revenue report, and an equipment/asset list. As the audit progresses, we will request additional documents by pillar — contracts, lease agreements, org chart, payroll records, software subscriptions. We provide a full document request list on Day 1.
Can the audit findings be used to renegotiate the purchase price?
Yes — this is the primary use case. Every high-severity finding includes a specific price adjustment recommendation at your agreed multiple. Buyers use our deal recommendation memo to renegotiate purchase price, add representations and warranties, structure earnouts, or walk away entirely. The memo is specifically formatted for LOI renegotiation conversations.
How is the audit delivered?
You receive a structured audit report organized by pillar, each section containing: the checkpoints reviewed, findings at each checkpoint (scored High, Medium, or Low), supporting documentation references, and purchase price impact calculations. A separate deal recommendation memo summarizes all renegotiation opportunities with specific dollar amounts. Both documents are in PDF format, ready to share with your attorney and lender.
