Business acquisition due diligence: what to check first
A practical buyer checklist for cash flow, bookkeeping, working capital, concentration risk and negotiation.
Due diligence starts by reconciling reported profit with actual cash movement. A buyer should check sales quality, collections, debt, inventory, tax and legal commitments, customer concentration, owner dependence and the realistic cost of running the company after closing.
Start with the quality of financial information
A clean presentation is not the same as a reliable business. Request several years of income statements, balance sheets, bank statements and tax filings, then reconcile significant differences. The interview with M&A analyst Elena Yankovskaya highlights how weak management accounting and figures that exist only in an owner’s memory create uncertainty over what is actually being purchased.
Ask what happens if the seller is no longer available to explain day-to-day operations. If sales, purchasing and profitability cannot be reproduced from records, the buyer needs a deeper review and a wider margin of safety.
Check cash rather than accounting profit
Profits can look healthy while cash is trapped in receivables, stock or long customer payment terms. Map receivables aging, inventory turnover, supplier payables, seasonal cash needs, payroll and customer deposits. Estimate normalized cash that could support debt service and investor distributions after necessary reinvestment.
Distinguish recurring operational cash flow from one-time owner actions, such as temporarily delaying vendor payments before a sale. A quality-of-earnings review may be appropriate for material acquisitions.
Investigate dependency and hidden obligations
Assess how much revenue depends on a few customers, employees, licenses, suppliers or the seller personally. Review material contracts, leases, permits, litigation and related-party transactions. The UAE-focused conversation with Gadzhimurad Magomedrasulov stresses that a transaction is not just agreeing a headline price: structure and transferability matter.
Document what will remain with the acquired entity, what requires consent and what must be rebuilt after the transaction. This is particularly important in cross-border acquisitions.
Turn diligence findings into decisions
Classify findings into deal-breakers, price adjustments, protections in transaction documents and an operating plan. An unresolved issue can justify an escrow, earn-out, working-capital adjustment or a decision not to proceed—depending on law and transaction structure.
There is no universal “correct discount” to demand. Strategic buyers may value synergies differently from a financial buyer. Underwrite the asset you can actually operate, not just the attractive scenario in the seller deck.

Common questions
Does EBITDA show how much cash an owner can withdraw?
No. EBITDA excludes some economically important costs. Examine working capital, capital expenditures, debt service and taxes before estimating distributable cash.
Is every accounting problem a deal-breaker?
No. Some issues can be remediated or priced, but unreliable information raises diligence costs and uncertainty.
