Acquisition Due-Diligence Checklist

Track diligence requests for a business acquisition across transaction scope, entity authority, financials, assets, liabilities, contracts, employees, licenses, cybersecurity, financing, ROBS boundaries, closing deliverables, and post-close integration.

Direct answer: this checklist helps a buyer organize evidence and assign follow-up before using ROBS, SBA debt, seller financing, buyer cash, or another funding mix. It does not make a legal, tax, accounting, fiduciary, lender, SBA, valuation, insurance, environmental, cybersecurity, or investment conclusion.

How to use the checklist without overstating it

Use the checklist as a planning control, not as a representation that diligence is complete. A business acquisition can involve legal existence, financial quality, contracts, employees, taxes, licenses, financing, and benefit-plan issues. SBA 7(a) materials confirm that loans can support changes of ownership and working capital, while SBA SOP materials govern lender origination requirements [1] [2]. That means the diligence file should tie requested evidence to both deal risk and financing conditions.

The status labels are intentionally narrow. Not started means the request has not been reviewed. In review means someone is evaluating the evidence. Cleared for planning means the item has enough support for planning at this stage. Needs follow-up means an issue, gap, or condition remains. Not applicable means the item is excluded from the progress denominator but still counted separately.

Do not paste confidential documents into this page. The checklist stores nothing, has no note fields, and does not need cookies, query parameters, or local storage. Keep names, account numbers, tax IDs, payroll data, customer data, passwords, and private documents in the secure diligence room or advisor-controlled system.

Decision boundaries and escalation examples

Use advisor escalation when the evidence changes deal economics, closing permission, employee obligations, financing, or ROBS plan operations. Examples include:

  • A seller credit appears in both the purchase-price adjustment and the lender sources-and-uses schedule. Ask the CPA and lender to prevent double counting.
  • The buyer entity is an LLC, but the ROBS structure expects a C corporation sponsoring a qualified plan. Coordinate deal counsel, ERISA counsel, and the ROBS provider before documents are signed.
  • A UCC search, tax notice, or litigation demand suggests a lien or contingent liability. Closing counsel should connect payoff, release, indemnity, escrow, or purchase-structure decisions.
  • Employees will become eligible for the buyer corporation's qualified plan after closing. ERISA counsel or the plan administrator should review eligibility, disclosures, testing, and employer-stock availability.
  • A franchisor, landlord, regulator, lender, or supplier must consent before transfer. Track the condition owner, deadline, and consequence in the purchase agreement.

ROBS diligence boundaries

IRS materials describe a ROBS transaction as involving a new C corporation, a qualified plan, a rollover or transfer to that plan, and the plan's purchase of employer stock [3] [4]. The checklist therefore separates ROBS-funded corporate equity from buyer cash and asks for plan documents, trust evidence, stock purchase records, corporate resolutions, and valuation support.

IRS materials also identify valuation, filing, prohibited-transaction, business-failure, bankruptcy, lien, and dissolution concerns, and state that determination letters do not approve plan operations [3]. A checked or cleared status in this tool does not establish adequate consideration, fiduciary prudence, plan qualification, prohibited-transaction compliance, or employee access under plan terms.

Primary-source context for regulated areas

Employee benefit plan data can create cybersecurity responsibilities. DOL states that EBSA cybersecurity guidance applies to employee benefit plans and that cybersecurity is a concern for all such plans [5]. The checklist includes plan-service-provider and access-control prompts for that reason.

Some acquisitions, franchises, distributorships, or seller-assisted opportunities may involve disclosure regimes or regulated transfer approvals. State licensing, professional-board, alcohol, childcare, healthcare, environmental, franchise, and other regulated industries require jurisdiction-specific review beyond this page.

Model affordability separately

Diligence issues should feed a separate price, debt-service, DSCR, and liquidity model.

What to record outside this browser tool

Keep a secure issue log with request, document location, reviewer, status, deadline, decision, source document, and unresolved risk. Use this page only for category-level status tracking. That keeps private diligence evidence out of browser form fields while preserving a defensible review process.
