Business Due Diligence Checklist for Buyers

Financial records

Request enough evidence to reconcile reported earnings and understand cash needs.

• Three to five years of tax returns, income statements, balance sheets, and cash-flow statements.
• Current year-to-date statements and the comparable prior-year period.
• Bank statements, accounts receivable and payable aging, inventory, debt, and capital-expenditure history.
• A schedule and support for every proposed owner add-back or normalization.

Legal, ownership, and tax

Have qualified advisers confirm the seller’s authority to transact and identify obligations that could follow the assets or entity.

• Formation documents, ownership records, permits, licenses, contracts, leases, liens, litigation, claims, and regulatory correspondence.
• Federal, state, payroll, and sales-tax filings and notices.
• Intellectual property, privacy obligations, and required third-party consents.

Operations and commercial quality

Determine whether the company’s revenue and operating capability will transfer after the owner exits.

• Top customers and suppliers, contract terms, concentration, churn, pipeline, pricing, and competitive position.
• Employee roster, compensation, tenure, benefits, classification, key-person risk, and retention concerns.
• Equipment condition, facilities, maintenance, insurance claims, systems, cybersecurity, and business continuity.

Turn findings into decisions

A checklist is useful only when exceptions affect the deal. Assign each item a status, evidence source, reviewer, and due date. Classify unresolved issues as informational, a closing condition, a price or structure adjustment, a post-close action, or a reason to withdraw.

What the checklist cannot replace

The scope changes by industry, state, transaction structure, and company size. Use legal, tax, accounting, environmental, insurance, lending, and technical professionals when the issue requires licensed or specialized judgment.
