Business acquisition checklist

General guidance only. Due diligence scope depends heavily on the target business, industry, and deal structure. This checklist identifies common areas for review - it doesn't replace a professional due diligence process led by attorneys, accountants, and industry specialists. See our full disclaimer.

A business attorney leads formal due diligence, drafts and negotiates the purchase agreement, and structures the deal to minimize your post-closing risk exposure.

Why does the asset vs. stock purchase decision matter so much?

In an asset purchase, the buyer acquires specific assets and liabilities they agree to assume - generally leaving behind unknown or undisclosed liabilities with the seller. In a stock purchase, the buyer acquires the entire legal entity, including all its liabilities, known and unknown, unless specifically excluded in the purchase agreement.

Asset purchases generally offer buyers better protection against hidden liabilities (undisclosed lawsuits, unpaid taxes, environmental issues) but can be more complex to execute, since each asset and contract may need individual transfer, and some contracts require third-party consent to assign. Stock purchases are often simpler to execute but expose the buyer to more undisclosed risk, making thorough due diligence even more critical.

Once you've settled on deal structure, use the business entity selector to confirm the right structure for your acquiring entity, and the contract clause analyzer to review the purchase agreement itself.

What's the most commonly overlooked due diligence category?

Contract review is frequently underweighted relative to financial due diligence. Buyers focus heavily on verifying financial statements but sometimes miss that key customer or vendor contracts include "change of control" provisions allowing the other party to terminate if the business is sold - discovering this after closing, when a major customer walks away, can undermine the entire value of the deal.

Similarly, employee-related liabilities (unpaid wages, misclassified workers, pending discrimination claims) are sometimes underexplored relative to their potential financial and legal exposure. Use the misclassified worker screener if you have concerns about the target's workforce classification practices during due diligence.

How long should due diligence realistically take?

Timeline varies enormously by deal size and complexity, but rushing due diligence to close a deal quickly is one of the most common regrets acquirers report after the fact. Smaller, simpler acquisitions might reasonably complete diligence in 3 to 6 weeks, while larger or more complex deals often take 2 to 4 months or longer, particularly when regulatory approvals or complex contract assignments are involved.

Building adequate time into the deal timeline for professional due diligence (accountants reviewing financials, attorneys reviewing contracts and legal exposure, and where relevant, industry specialists reviewing operations) is far cheaper than discovering a serious problem after the deal has closed and the seller's obligations to cooperate have ended.

Frequently asked questions

Representations and warranties are statements the seller makes about the business (accurate financials, no undisclosed litigation, valid ownership of assets, compliance with laws) that form part of the purchase agreement. If a representation turns out to be false, the buyer typically has a contractual right to seek indemnification for resulting losses, which is why thorough reps and warranties, backed by adequate escrow or holdback provisions, are a critical protective mechanism beyond due diligence alone - due diligence reduces the chance of surprises, while reps and warranties provide recourse if surprises happen anyway.

An escrow or holdback sets aside a portion of the purchase price (commonly 10% to 20%, held for 12 to 24 months) to cover potential indemnification claims if a representation or warranty turns out to be false, or if an undisclosed liability surfaces after closing. This gives the buyer recourse without needing to pursue a seller who may be difficult to locate or collect from after the deal closes and proceeds have been distributed. The exact percentage and duration are heavily negotiated and depend on the perceived risk level of the specific deal.

Strongly recommended for any acquisition of meaningful size. A QoE report, prepared by an independent accounting firm, goes beyond standard financial statement review to assess the sustainability and accuracy of reported earnings - identifying one-time items inflating profitability, aggressive accounting practices, or revenue recognition issues that a simple review of tax returns or basic financials might miss. Sellers sometimes present financials in the most favorable light possible, and a QoE report provides an independent check specifically designed to catch this.

Depends heavily on deal structure. In a stock purchase or merger, employees generally continue under the same employment terms unless changed after closing. In an asset purchase, employees are technically terminated by the seller and rehired by the buyer, which can trigger notice requirements under the WARN Act for larger workforce changes, and requires careful handling of benefits continuity, accrued PTO, and employment agreement transitions. Review existing employment agreements and any change-of-control provisions during due diligence to understand your specific obligations and options.

Very important, particularly for businesses where the seller's personal relationships and expertise drive significant value. Without a seller non-compete, the seller could theoretically start a competing business immediately after closing, using knowledge and relationships built at the business they just sold, undermining the value the buyer paid for. Non-competes tied to the sale of a business generally receive more favorable enforceability treatment under state law than employment-based non-competes, even in some states that heavily restrict the latter, since courts recognize the buyer's legitimate interest in protecting the goodwill they purchased.
