Clarity before commitment
What is buy-side financial due diligence?
Buy-side financial due diligence is an independent review of a target company's financial information, commissioned by the buyer before an acquisition. It examines the quality of earnings, cash flow, working capital, net debt and financial risks, so the buyer can confirm the price, negotiate terms and avoid paying for problems they did not know about.
It is different from an audit. An audit gives an opinion on historical accounts. Due diligence answers the buyer's commercial questions: what profit is genuinely repeatable, how much cash the business will need after completion, and what liabilities should come off the price.
We work with first-time and repeat SME acquirers, management buyout teams, search funds and investors. Each review is scoped to the target, the deal structure and the decisions you need to make.
When buyers bring us in
Situations where buy-side due diligence pays for itself
Buying your first business
You have agreed heads of terms and need an independent view before committing personal capital or debt.
Acquiring a competitor or supplier
You know the market, but need to test whether the target's numbers support the price and your integration plan.
Management buyout
The management team is buying and needs to understand maintainable earnings and how much debt the business can carry.
Search fund or investor acquisition
Your investors expect evidence-based findings on earnings quality, cash conversion and downside risk.
Lender or investor requirement
A bank or backer wants financial diligence before releasing acquisition funding.
Something does not add up
Profit looks strong but cash looks weak, or the seller's figures change between versions. You need answers before exclusivity runs out.
What's included
Understand the business. Challenge the price.
Your proposal sets out exactly what is included, what is excluded and what you receive. Most reviews cover some or all of the following.
Quality of earnings
Test how sustainable reported profit is, adjusting for one-off income, exceptional costs, owner remuneration and accounting judgements.
Revenue and margin analysis
Examine revenue mix, customer concentration, recurring income and margin trends, and where performance relies on a few customers or assumptions.
Working capital and cash conversion
Analyse debtors, creditors, stock and seasonality, and the gap between profit and cash. Establish a normal level of working capital for the deal.
Net debt and debt-like items
Review borrowings, cash and exposures such as deferred income, tax liabilities, director loans and leases that may reduce the equity value.
Forecasts and downside scenarios
Challenge forecast assumptions against historical trading and funding needs, and make the key sensitivities visible.
Decision and negotiation support
Turn findings into price adjustments, warranty and indemnity points, and questions for the seller. We coordinate with your legal and tax advisers.
What we look for
Common financial red flags in SME acquisitions
These issues come up repeatedly in UK SME deals. Each one can change the price, the structure or whether you proceed at all.
- Overstated adjustments to EBITDA"One-off" costs that recur every year, or owner costs added back without evidence.
- Customer concentrationA large share of revenue from one or two customers, often without long-term contracts.
- Working capital squeezed before saleDebtors chased hard and suppliers paid late to flatter cash at completion.
- Revenue recognised too earlyIncome booked before it is earned, particularly on projects, subscriptions and deposits.
- Hidden debt-like itemsUnpaid tax, HMRC time-to-pay arrangements, deferred income, director loans or overdue creditors.
- Weak financial recordsManagement accounts that do not reconcile to the statutory accounts, bank or VAT returns.
- Margins that do not hold upGross margin propped up by stock valuation, capitalised costs or unusual period-end entries.
- Forecasts that ignore historyHockey-stick growth with no evidence from pipeline, contracts or past trading.
Choosing the right review
Buy-side due diligence vs vendor due diligence vs audit
Each serves a different purpose. Buyers often receive vendor reports or audited accounts and wrongly assume no further work is needed.
| Buy-side financial DD | Red-flag review | Vendor DD | Statutory audit | |
|---|---|---|---|---|
| Commissioned by | The buyer | The buyer | The seller | The company |
| Purpose | Inform price, terms and the decision to proceed | Spot deal-breakers early | Prepare the business for sale and speed up the process | Opinion on historical accounts |
| Depth | Tailored, detailed review | Narrow and fast | Broad, seller-led | Compliance-focused |
| Looks forward? | Yes: forecasts, cash needs and downside | Limited | Often | No |
| Best for | Buyers moving towards completion | Buyers deciding whether to proceed | Sellers preparing an exit | Annual reporting |

Start with the right question
Match the review to your decision
Choose the situation closest to yours. Final scope and timing are agreed after a first conversation.
Prioritise headline earnings, cash conversion, customer concentration and major information gaps. A red-flag review is narrower than full financial due diligence, and we will be clear about what it does not cover.
A financial review covering quality of earnings, working capital, net debt and forecasts, with a clear information request list and a findings discussion before you negotiate final terms.
Focus on maintainable earnings, funding capacity and downside headroom, alongside the financial risks and assumptions that matter to lenders backing the buyout.
Discuss the right scope for your dealHow we work
From first conversation to a clear next move
Define the decision
Agree the target, deal stage, access to information, timetable and who will rely on the report.
Request and analyse
Issue a tailored information request, review the records, test key reconciliations and question management.
Surface the findings
Flag material issues as they emerge, separating evidence from open questions, so nothing lands as a surprise.
Support your next move
Deliver the agreed report and talk through what it means for price, funding, completion mechanics and further diligence.

Kish is an ICAEW Chartered Accountant whose background spans Big Four audit, investment banking and corporate advisory. He founded Consult EFC to bring that standard of financial analysis to UK founders, SME acquirers and management teams.
Every engagement starts with the question you need answered, not a generic checklist. We agree the scope, explain our assumptions and make the findings usable in negotiation.
Book a free 30-minute callBuyer outputs and the next decision
A practical findings pack links each issue to its evidence, financial effect, unanswered question and proposed follow-up. The agreed format can include:
- A decision summary prioritising material findings and gaps.
- Reported-to-adjusted earnings, revenue and cash conversion schedules.
- Working capital, cash, debt and debt-like item analysis using proposed deal definitions.
- Forecast sensitivities, outstanding requests and questions for management or other advisers.
For example, a recurring cost described as an add-back needs evidence before the buyer accepts higher maintainable earnings. The review can explain the issue; the SPA and negotiations determine any contractual consequence.

Buy-side financial due diligence FAQs
Who commissions buy-side financial due diligence?
The acquiring business, management buyout team or investor commissions the review to support an acquisition decision. The scope reflects the target, deal structure, risks, information available and intended users.
How is buy-side due diligence different from seller preparation?
Buy-side work challenges the target’s information for the purchaser. Seller preparation helps the owner organise, reconcile and explain information before a buyer investigates it. They serve different clients and do not replace one another.
Is financial due diligence an audit or assurance engagement?
No. Financial due diligence is a transaction-focused review within an agreed scope. It does not provide an audit opinion or examine every matter that could affect the acquisition. We explain the evidence, limitations and areas requiring other specialist review.
What will the buyer receive?
The agreed output can include an executive findings summary, supporting schedules for earnings, revenue, working capital and net debt, open questions and implications for the transaction. Format, recipients and any reliance terms are confirmed before work begins.
Can you provide an initial red-flag review?
Yes, where agreed. A red-flag review addresses selected decision-critical areas with a narrower scope than a fuller review. It can leave important matters unexamined, so the proposal and report state its limits.
Which target-company records are needed?
Normally accounts, monthly management information, ledger data, bank and debt schedules, revenue by customer, contracts, receivables and payables ageing, payroll, stock and forecasts. The request list is tailored to the target and scope.
When should a buyer commission the review?
Agree the scope once the proposed transaction and access to target information are sufficiently clear. Leave time before signing to investigate findings and coordinate with legal, tax and other advisers. Exclusivity and the deal timetable affect the practical sequence.
Does financial due diligence determine the final price?
No. Findings can inform negotiations, forecasts and completion-account definitions. The buyer and seller negotiate the price and contractual terms, with legal advice where needed. A finding does not automatically create a particular price adjustment.
How are fees and delivery dates agreed?
We review the target, data condition, depth of work, intended outputs and deadline before proposing a fee and timetable. Missing information or additional questions can affect delivery and are discussed promptly.
Can a bank or another party rely on the report?
Only where the engagement and reliance arrangements expressly allow it. We identify intended recipients and permitted use in writing. Legal, tax, commercial and technical reviews remain separate unless specifically agreed.
