How to Prepare for Business Sale Due Diligence in Florida

When you accept a letter of intent from a qualified buyer, the deal isn't done—it's just starting. The 45 to 90 days that follow, known as due diligence, are when buyers verify every claim you've made about your business. They will pull your financials, interview your key employees, review your customer contracts, examine your legal history, and pressure-test your EBITDA. If what they find matches what you represented, you close. If it doesn't, the price drops—or the deal dies entirely.

At CBH Business Group, we've guided sellers through hundreds of Florida business transactions. The sellers who close quickly and at full price are the ones who prepared long before a buyer showed up. This guide walks through exactly what due diligence covers, what gets deals killed, and what you need to have ready before you go to market.

What Buyers Actually Examine During Due Diligence

Due diligence is not a single checklist—it's a full audit of your business across five categories: financial, legal, operational, commercial, and tax. Buyers in the Florida lower-middle market (businesses doing $3M to $50M in revenue) will typically deploy an accountant, an attorney, and often a third-party quality of earnings (QofE) firm to conduct the review in parallel.

Here's what falls under each category:

Financial: Three to five years of audited or reviewed financial statements, federal and state tax returns, monthly P&Ls, accounts receivable aging reports, accounts payable schedules, bank statements, and a normalized EBITDA recast that adjusts for owner perks, one-time expenses, and non-recurring revenue.

Legal: All customer and vendor contracts, lease agreements, employment agreements, non-compete agreements, intellectual property ownership, pending or historical litigation, and any regulatory compliance matters specific to your industry.

Operational: Organizational charts, key employee compensation and retention agreements, supplier relationships, technology systems, and process documentation that demonstrates the business runs without being entirely dependent on the owner.

Commercial: Customer concentration analysis (how much revenue comes from your top five clients), customer churn rates, pipeline health, marketing channels, and competitive positioning.

Tax: Sales and use tax compliance, payroll tax history, outstanding IRS or state notices, and any deferred tax liabilities that could affect the buyer's net return.

The Documents You Need to Prepare Before Going to Market

The businesses that close cleanly are the ones that have already assembled their documentation before a buyer ever asks. Waiting until you're in due diligence to pull together five years of financials, track down old contracts, and reconstruct employee agreements adds weeks to the process and signals disorganization to buyers who are paying close attention.

Start with this core document set:

• Federal tax returns (Form 1120 or Schedule C/K-1) for the last three to five years
• Monthly P&L statements for the current year-to-date and prior two years
• Balance sheets for the last three years
• Accounts receivable aging report (current)
• A normalized EBITDA recast with add-backs clearly documented and defensible
• All customer contracts and revenue agreements, including any auto-renewal or termination clauses
• Lease agreements for all locations (real estate, equipment, vehicles)
• Payroll records and current employee roster with compensation
• Business licenses, permits, and any professional certifications required in your industry
• Documentation of any pending litigation, past settlements, or regulatory actions
• Intellectual property registrations (trademarks, patents, software ownership)
• Vendor contracts and supplier agreements with key terms

If you're in a regulated Florida industry—healthcare, childcare, insurance, real estate, contracting—add your licensing records, any state board correspondence, and compliance documentation specific to your sector.

EBITDA Multiples by Industry in Florida: What's at Stake

Understanding why due diligence matters financially helps sellers take it seriously. A clean due diligence process that confirms your numbers protects your multiple. Problems uncovered mid-process typically result in price reductions of 0.5x to 2.0x EBITDA—sometimes more.

Industry	Typical EBITDA Multiple (Florida LMM)	Key Due Diligence Risk
HVAC / Home Services	4x – 6x	Customer concentration, technician dependency
Healthcare / Medical Practices	5x – 8x	Licensing compliance, payer mix, physician agreements
Construction / Roofing	3x – 5x	Bonding capacity, backlog verification, subcontractor agreements
Professional Services (CPA, Legal)	3x – 5x	Client portability, non-compete enforceability
SaaS / Technology	5x – 9x	Churn rate, IP ownership, recurring revenue quality
Manufacturing / Distribution	4x – 6x	Equipment condition, inventory accuracy, customer contracts
Landscaping / Pest Control	3x – 5x	Route documentation, equipment age, crew retention

A $2M EBITDA business trading at 5x is worth $10M. A 0.5x multiple reduction discovered in due diligence—say, because your top customer represents 35% of revenue—costs you $1M at closing. That's real money, and it's almost always preventable with advance preparation.

The Three Things That Kill Florida Business Deals in Due Diligence

After closing dozens of Florida transactions and watching others fall apart, CBH consistently sees three deal-killers that could have been addressed before going to market.

1. Undisclosed liabilities. Buyers run detailed searches on Florida business entities—UCC filings, judgment searches, tax liens, pending lawsuits, and environmental liabilities. If something surfaces in due diligence that wasn't disclosed upfront, trust collapses immediately. Buyers don't just reprice the issue—they start questioning everything else you've told them. Disclose proactively and document the resolution. A settled lawsuit from three years ago is not a deal-killer. An undisclosed ongoing dispute absolutely can be.

2. Customer concentration above 25%. This is the single most common issue we see in Florida service businesses. If your top customer represents 30%, 40%, or 50% of your revenue, buyers apply a significant risk discount because a single relationship termination could cripple the business post-close. The fix takes time—12 to 24 months of actively diversifying your revenue base—which is why we recommend starting the process two years before you plan to sell. If you're already under LOI with concentration risk, be prepared for a lower multiple, earnout provisions, or a longer seller holdback period.

3. Owner dependency that isn't documented away. If the business runs through you—you hold the key customer relationships, you're the licensed professional, you make all major decisions—buyers will pay less because they're acquiring risk, not just cash flow. Documenting your processes, building a management layer, and transitioning customer relationships to your team before going to market directly increases what you'll get at closing. We've seen this single change move a multiple by half a turn.

How to Set Up a Virtual Data Room

A virtual data room (VDR) is a secure, organized digital folder system that houses all your due diligence documents. It's the professional standard in Florida M&A transactions at the $5M+ level and increasingly expected even in smaller deals. Setting one up before you go to market sends a signal to buyers that you're organized, prepared, and serious—and it dramatically compresses the time from LOI to close.

Your data room should be organized by category, not by document date or type. A clean structure looks like this:

• 01 – Financials: Tax returns, P&Ls, balance sheets, bank statements, EBITDA recast
• 02 – Legal: Contracts, leases, litigation history, IP registrations, corporate formation docs
• 03 – Operations: Org chart, key employee agreements, process documentation, equipment list
• 04 – Commercial: Customer list (can be anonymized initially), top 10 customer revenue breakdown, churn data
• 05 – Tax: State and local tax filings, sales tax compliance records, any IRS correspondence
• 06 – HR: Payroll summary, PTO liabilities, benefits summary, independent contractor agreements
• 07 – Insurance: Current policies with limits, claims history

Free tools like Google Drive work for basic use. Paid VDR platforms like Datasite, Intralinks, or even Dropbox Business add permissions management and audit trails—useful for tracking exactly what a buyer's team has reviewed. For most Florida lower-middle-market deals, a well-organized Google Drive or SharePoint folder is sufficient.

Timeline: What to Expect From LOI to Close

Florida business sales in the $3M to $30M range typically run on this timeline after an LOI is signed:

• Days 1–10: Buyer's legal team drafts the purchase agreement framework; VDR access is granted; buyer delivers due diligence request list.
• Days 10–45: Active due diligence phase—financial review, legal review, customer and vendor interviews, facility inspections if applicable.
• Days 30–60: Quality of earnings report delivered (if buyer engaged a QofE firm); purchase price adjustments negotiated based on findings; representations and warranties negotiated in the purchase agreement.
• Days 60–90: Final purchase agreement signed; financing commitments finalized (critical for SBA-financed deals); regulatory approvals obtained if required by industry.
• Days 75–90+: Closing date.

Sellers who arrive at due diligence without organized documentation routinely add 30 to 60 days to this timeline. In a rising interest rate environment, that delay is expensive for buyers—and can give them grounds to reprice or walk away from the deal entirely.
