What Is Due Diligence?
Due diligence is the investigation carried out before purchasing a business. Its purpose is to verify the seller's claims, identify risks and confirm that the business is worth the agreed purchase price.
Professional investors never rely solely on the information presented in a sales listing. Instead, they carefully examine financial records, legal documents, contracts, assets, customers and operational systems before completing a transaction.
Financial Due Diligence
Financial records provide the clearest picture of how a business performs. Buyers should request sufficient information to understand profitability, cash flow and future sustainability.
Financial Documents to Request
- Profit and Loss Statements
- Balance Sheets
- Cash Flow Statements
- Corporation Tax Returns
- VAT Records (if applicable)
- Bank Statements
- Sales Reports
- Accounts Receivable
- Accounts Payable
- Management Accounts
Financial Questions to Ask
- Is revenue increasing each year?
- Are profits consistent?
- Are there outstanding debts?
- What are the largest business expenses?
- How dependent is the business on one customer?
- Are there seasonal fluctuations?
Legal Due Diligence
Legal due diligence confirms that the business owns what it claims to own and that there are no hidden legal issues that could affect the purchase. A careful legal review protects buyers from unexpected liabilities after completion.
Documents to Review
- Certificate of Incorporation
- Articles of Association
- Shareholder Agreements
- Business Licences
- Insurance Policies
- Employment Contracts
- Commercial Property Leases
- Supplier Agreements
- Customer Contracts
- Non-Disclosure Agreements

Legal Questions to Ask
- Are there any ongoing legal disputes?
- Has the business received regulatory penalties?
- Does the business own all intellectual property?
- Are contracts transferable to a new owner?
- Are there outstanding warranty claims?
- Are all required licences current?
Operational Due Diligence
Operational due diligence helps determine whether the business can continue operating successfully after ownership changes. Buyers should understand how the business functions on a day-to-day basis and whether it relies heavily on the current owner.
