Business Sale Due Diligence Checklist for Texas Owners: 60-Item Data Room & Pre-LOI Audit
Signing a Letter of Intent (LOI) does not mean your business is sold—it means the buyer now has 60 to 90 days of binding exclusivity to audit every invoice, tax return, permit, and contract looking for reasons to re-price the deal. Over 40% of lower-middle-market transactions suffer a price retrade or stall between Day 25 and Day 45 of due diligence because the seller opened a data room before checking what was inside. Use this 6-workstream Texas due diligence checklist to audit your records before you grant exclusivity.
1. Six Due Diligence Workstreams Every Texas Buyer & SBA Lender Audits
Whether your buyer is a private equity platform, a regional strategic acquirer, or an individual operator backed by an SBA 7(a) acquisition loan (SBA SOP 50 10 8), their accountants and transaction attorneys request the exact same six folders on Day 1 of exclusivity:
| Diligence Workstream | Core Data Room Documents (Items 1–60) | Texas Statutory & Underwriting Standard | What Triggers a Price Retrade or Holdback |
|---|---|---|---|
| 1. Financial, QoE & Federal Tax (Items 1–12) | 3 years federal tax returns (Forms 1120-S / 1065 / 1120) + IRS Form 4506-C transcripts; 36-month monthly accrual P&L and balance sheets; 24-month bank statements for Proof of Cash; documented add-back binder; draft IRS Form 8594 allocation. | SBA SOP 50 10 8 IRS tax-transcript verification; IRC §1245 depreciation recapture; BVR / IBBA QoE standards. | Tax return revenue doesn’t tie to bank deposits, or personal expenses buried in COGS lack receipts (see How to Prepare Financials). |
| 2. Working Capital, AR/AP & WIP (Items 13–22) | 12-month trailing Net Working Capital (NWC) schedule; aged AR and AP reports; physical inventory count; job-by-job ASC 606 WIP schedule (Costs in Excess vs. Billings in Excess of Costs); deferred maintenance-contract revenue rollforward. | ASC 606 percentage-of-completion accounting; Texas Property Code Ch. 53 statutory 10% construction retainage rules. | Upfront customer mobilization deposits were spent before work started, creating a dollar-for-dollar WIP over-billing deduction at close. |
| 3. Texas State Tax & Payroll Clearances (Items 23–30) | Texas Franchise Tax Public Information & Ownership Reports; 36 months Texas Sales & Use Tax filings (resale/exemption certificates); Comptroller Form 86-114 request; 3 years IRS Form 941/940, W-2/1099 registers, and Texas Workforce Commission (TWC) unemployment tax account status. | Texas Tax Code §111.020 successor tax liability; Texas Labor Code Title 4 TWC experience-rating transfer; worker classification audit. | Missing resale certificates on commercial jobs or unfiled Franchise/Sales Tax returns force a 10%–20% closing escrow freeze until Form 86-114 clears. |
| 4. Trade Licenses, Permits & Regulatory (Items 31–40) | Active corporate and individual qualifier licenses; municipal permit logs; EPA/TCEQ environmental registrations; OSHA 300/300A injury logs and Workers’ Comp Experience Modification Rate (EMR) letters for the past 3 years. |
TDLR (Tex. Occ. Code Ch. 1302 ACR & Ch. 1305 Electrical); TSBPE (Ch. 1301 Plumbing RMP & 22 TAC §367.3); SBA SOP 50 10 8 12-month seller transition cap. | Selling founder is the sole Master Electrician, RMP, or Class A ACR qualifier, or company EMR exceeds 1.15 (see Texas license rules). |
| 5. Customer Contracts, MSAs & Concentration (Items 41–50) | Top 20 customer revenue history (3 years, anonymized in Stage 1); active Master Service Agreements (MSAs), PM contracts, and open purchase orders; vendor/distributor supply agreements; warranty reserve and callback history. | Change-of-control & anti-assignment clauses in commercial MSAs; customer concentration thresholds (>15% single account). | Top 2 customers represent 40%+ of revenue on terminable-at-will POs, triggering a 25%–35% contingent earnout holdback (see Concentration Guide). |
| 6. Corporate Governance, Liens, Fleet & Leases (Items 51–60) | Certificate of Formation, Operating Agreement / Bylaws, and Texas Certificate of Fact (Status); SOS UCC-1 lien search; bank/equipment payoff letters; TxDMV vehicle titles; commercial real estate NNN lease (or OpCo/PropCo draft lease) + Phase I ESA if real estate is included. | Texas Business Organizations Code (TBOC); Texas Bus. & Com. Code Ch. 9 UCC-3 releases; commercial landlord assignment consent. | Old SBA/bank blanket UCC-1 liens were never terminated, or third-party landlord refuses to assign the shop lease without a personal guarantee extension. |
2. How to Stage Your Data Room Across the 60-Day Post-LOI Exclusivity Window
Never dump unredacted customer contacts, employee cell numbers, or competitive bid sheets into a virtual data room on Day 1. Use a staged disclosure gate tied to buyer milestones (see our Unsolicited PE LOI Checklist):
| Diligence Window | What Buyer & Lender Audit | What Seller Releases in Data Room | Mandatory Buyer Milestone Gate |
|---|---|---|---|
| Pre-LOI (Days -30 to 0) | Historical earnings power, revenue mix, add-back credibility, and high-level working capital baseline. | 3-year recast T12 accrual summary, anonymized customer concentration table (Customer #1–#20), and proposed NWC peg formula. | Buyer signs NDA and submits written LOI with explicit NWC peg formula and cash-at-close breakdown. |
| Stage 1A: Days 1–20 (Financial & QoE) | 24-month Proof of Cash, general ledger transaction export, tax transcripts (Form 4506-C), and WIP/inventory cut-off. | Full QuickBooks accrual backup (customer PII masked), bank statements, tax returns, and invoice-backed add-back binder. | Day 25 Gate: Buyer delivers preliminary Quality of Earnings (QoE) findings and confirms headline price in writing. |
| Stage 1B: Days 21–40 (Legal, License & Lender) | Corporate governance, UCC liens, insurance/EMR, lease assignment, TDLR/TSBPE qualifier continuity, and SBA/senior bank underwriting. | Redacted MSA templates, equipment/fleet title list, insurance policies, qualifier agreement, and initial Asset/Stock Purchase Agreement draft. | Day 40 Gate: Buyer delivers formal bank/SBA credit commitment letter and initial Purchase Agreement mark-up. |
| Stage 2: Days 41–60 (Final Schedules & Close) | Final Disclosure Schedules, unredacted customer contract verification, Texas Comptroller Form 86-114 clearance, and closing funds flow. | Unredacted customer names, key-manager transition meetings, UCC-3 payoff letters, and signed Form 8594 / Closing Statement. | Day 60 Wire: Escrow release and Day-1 wire transfer (model yours in our Seller Net Proceeds Calculator). |
3. Four Texas Diligence Traps to Fix 90 Days Before Opening a Data Room
1. Clear Dormant UCC-1 Liens at the Texas Secretary of State
Paid-off SBA loans, EIDL loans, or equipment leases often leave active UCC-1 financing statements on file in Austin. Run a $15 Texas SOS UCC search now and force prior lenders to file UCC-3 terminations before a buyer’s attorneys use them to delay closing.
2. Audit Sales Tax Exemption & Resale Certificates
In Texas commercial remodeling and industrial service work, missing Texas Sales & Use Tax resale/exemption certificates (Form 01-339) create statutory successor liability under Texas Tax Code §111.020. Audit your top 25 commercial accounts so your Comptroller Form 86-114 clears cleanly.
3. Convert 1099 Crew Leaders or Lock In W-2 Qualifiers
Buyers scrutinize worker misclassification (1099 installers driving company trucks) and single-point-of-failure trade licenses. Elevate a W-2 manager as your registered TDLR or TSBPE qualifier with a stay-bonus agreement before diligence begins.
4. Pre-Draft Your Disclosure Schedules & NWC Collar
Most deal fatigue happens in Weeks 5–7 when sellers scramble to populate 40 pages of APA Disclosure Schedules. Build your asset register, contract list, and 12-month accrual NWC peg before signing the LOI.

Questions Texas Owners Ask About Business Sale Due Diligence
How long does due diligence take when selling a business in Texas?
In lower-middle-market Texas business sales ($1M to $25M enterprise value), binding post-LOI due diligence typically runs 45 to 75 days for private equity add-ons and 60 to 90 days when SBA 7(a) acquisition financing is involved under SBA SOP 50 10 8. Assembling your 60-item data room before signing the LOI routinely cuts 20 to 30 days off the closing clock and eliminates week-6 price retrades.
Why do buyers retrade the purchase price during due diligence?
Over 40% of lower-middle-market deals suffer a price retrade or structure change between Day 25 and Day 45 of exclusivity because the buyer’s Quality of Earnings (QoE) team discovers unverified seller add-backs, cash-to-accrual revenue cut-off errors, unrecorded WIP over-billings (billings in excess of costs), or undisclosed customer churn while the seller is locked into a binding no-shop period.
What is a Texas Comptroller Form 86-114 Certificate of No Tax Due and why does it hold up closings?
Under Texas Tax Code §111.020, a buyer of a Texas business becomes personally liable for the seller’s unpaid Texas Franchise Tax and Sales & Use Tax up to the purchase price unless the buyer withholds funds in escrow or obtains an official Certificate of No Tax Due (Form 86-114) from the Texas Comptroller of Public Accounts. Requesting Form 86-114 and TWC unemployment tax clearance early prevents a 10% to 20% tax-escrow freeze at closing.
When should I share customer names, employee wages, and vendor pricing in the data room?
Never upload unredacted customer names, technician cell numbers, or proprietary vendor rebates in Stage 1 (pre-LOI). Use anonymized Customer IDs (Customer #1, #2, #3) and masked employee rosters through LOI execution and initial QoE proof-of-cash verification; release unredacted customer contracts and key-employee introductions only in Stage 2 (the final 10 to 15 days before closing) after QoE and lender credit approval are complete.
What UCC-1 and equipment title documents are required to close a cash-free, debt-free sale?
To close a cash-free, debt-free transaction in Texas, your counsel must run a Texas Secretary of State UCC lien search (Texas Business & Commerce Code Chapter 9), obtain formal payoff letters and UCC-3 termination commitments from every bank, SBA lender, or equipment lessor, and assemble clear TxDMV certificates of title for all service trucks, trailers, and titled rolling stock.
