The CFO's Guide to Transaction-Ready Financials: What Buyers Actually Look At
John Stroud
Founder & CEO · 10 April 2026

A buyer's due diligence team does not read your financials the way your board does. Your board sees a growth story. Their analysts see a set of claims to be tested, assumptions to be challenged, and risks to be priced.
The gap between how sellers present their numbers and how buyers interpret them kills more mid-market deals than any other single factor. Understanding the different playbooks for buy-side and sell-side due diligence helps explain why. According to Embark, when a buyer's quality of earnings analysis reduces adjusted EBITDA by more than 15-20% below what the seller represented, the deal reprices or dies.
This guide covers what buyer DD teams actually focus on, where sellers most commonly stumble, and how to prepare before the first information request lands.
What Buyers Actually Look At
Buyer due diligence teams don't review your financials sequentially. They run five parallel workstreams, each designed to stress-test a specific dimension of your business.
Revenue Quality
The first question isn't "how much revenue?" — it's "how reliable is it?" DD teams decompose revenue by customer concentration, contract type, recurring vs. one-time, and geographic mix. They're looking for:
- Customer concentration risk — If your top 3 clients represent more than 30% of revenue, expect detailed questions about relationship stability and contract renewal history
- Revenue recognition practices — Aggressive recognition (booking multi-year contracts upfront, recognising revenue before delivery) gets flagged immediately
- Growth drivers — Organic growth vs. acquisition-driven vs. price increases vs. volume. Each carries different valuation implications
Earnings Normalisation
This is where most sellers get surprised. Buyers will reconstruct your EBITDA from scratch, adjusting for:
- Owner compensation above market rate
- One-time costs the seller claims won't recur
- Related-party transactions at non-market prices
- Expenses run through the business that benefit the owner personally
The most common DD finding: sellers overstate adjusted EBITDA by 15-25%. If your "normalised" EBITDA includes more than three adjustments, expect pushback on every one.
Working Capital
Buyers model a "normal" level of working capital required to run the business. Deviations from this norm at close become price adjustments — often material ones. They focus on:
- Accounts receivable ageing — A spike in 60+ day receivables signals collection problems
- Inventory levels — Excess or obsolete stock reduces the working capital baseline
- Payables timing — Stretching payables to inflate cash at close is transparent and penalised
Legal and Compliance Exposure
Financial DD teams coordinate with legal DD to identify contingent liabilities. Pending litigation, regulatory investigations, product warranty claims, and environmental exposure all get quantified and risk-adjusted.
Technology and IP
For technology-driven businesses, buyers assess IP ownership, key person dependencies in the development team, technical debt levels, and data security posture. A single unresolved cybersecurity vulnerability can delay or repricing a deal.
The Quality of Earnings Trap
Quality of Earnings (QoE) analysis is the single most important document in any transaction. The buyer will commission their own, typically from a Big 4 or mid-tier accounting firm. What you need to understand:
Your internal EBITDA is not what buyers will calculate. Every adjustment you've made will be challenged. Buyers' QoE analysts are specifically trained to find adjustments that don't hold up under scrutiny.
The best defence is offence. Commission your own sell-side QoE analysis before going to market. This lets you identify and address vulnerabilities before the buyer's team finds them. It also signals professionalism and reduces perceived risk.
Timing matters. A sell-side QoE completed 3-6 months before launch gives you time to fix issues. One completed the month before launch is just a preview of bad news.
A 12-Point Readiness Checklist
Before your first meeting with a potential buyer, every item on this list should be addressed:
| # | Area | Action | Priority |
|---|---|---|---|
| 1 | Accounting basis | Convert to accrual accounting if on cash basis | Critical |
| 2 | Chart of accounts | Clean up, standardise, remove legacy categories | High |
| 3 | Monthly close | Implement consistent monthly close process with reconciliations | Critical |
| 4 | Quality of earnings | Commission sell-side QoE from reputable firm | Critical |
| 5 | Working capital | Prepare 24-month working capital schedule with seasonality analysis | High |
| 6 | Revenue breakdown | Document revenue by customer, contract type, geography, and channel | High |
| 7 | Normalisation schedule | Prepare defensible EBITDA adjustments with supporting documentation | Critical |
| 8 | Related-party transactions | Document all related-party dealings at arm's length pricing | High |
| 9 | Tax compliance | Resolve any outstanding tax matters; obtain clearance certificates | Medium |
| 10 | Contracts | Organise all material contracts; flag change-of-control clauses | High |
| 11 | Data room | Populate virtual data room with 3 years of financials, contracts, and org docs | Critical |
| 12 | Management reporting | Prepare monthly management pack showing KPIs buyers will want | Medium |
The 80/20 rule of sell-side prep: Items 1, 3, 4, and 7 above address 80% of the issues that cause deals to stall or reprice. If you only have time for four things, do those four.
How AI Pre-Screens Your Own Financials
The traditional approach to sell-side preparation requires months of manual work and expensive advisory fees. AI-powered analysis changes the equation.
An AI platform can review your financial data, contracts, and operational documents in hours rather than weeks — identifying the same issues a buyer's DD team will find. This gives you a preview of your vulnerabilities before you're in the spotlight.
Specifically, AI analysis can:
- Flag revenue recognition practices that deviate from industry norms
- Identify working capital anomalies that would trigger buyer scrutiny
- Detect contract clauses (change of control, assignability restrictions) that affect deal structure
- Map customer concentration risk across revenue, receivables, and forward pipeline
- Score your data room completeness against standard DD request lists

The goal isn't to hide problems. It's to find them first, fix what you can, and have defensible explanations for what you can't. For a step-by-step look at what this rapid diagnostic looks like in practice, see how AI pre-screens your business for exit readiness in 48 hours.
Frequently Asked Questions
When should a CFO start preparing for a transaction?
Ideally 12-18 months before going to market. This provides time to clean up accounting practices, commission a sell-side QoE, resolve outstanding issues, and implement the reporting discipline buyers expect. Starting 6 months out is workable but limits your ability to address structural issues.
What is quality of earnings and why does it matter?
Quality of earnings (QoE) is an independent analysis that reconstructs a company's true earnings by adjusting for non-recurring items, normalising owner compensation, and testing revenue recognition practices. According to Northstar Financial Advisory, it's the single most influential document in setting final transaction value.
How much does sell-side due diligence typically cost?
Traditional sell-side QoE and financial DD from a mid-tier accounting firm typically costs $50,000-$150,000 for mid-market transactions ($10M-$200M enterprise value). AI-powered pre-screening can provide initial analysis at a fraction of this cost, helping prioritise where to invest in detailed advisory work.
What causes deals to fall apart during financial due diligence?
The most common deal-killers are: EBITDA adjustments that don't withstand scrutiny (reducing value below the seller's expectations), undisclosed liabilities discovered during review, working capital disputes, and customer concentration risk that wasn't adequately disclosed upfront.
Should the CFO or the CEO lead the sell-side process?
The CFO should lead financial preparation and data room organisation. The CEO should lead the narrative — the growth story, strategic vision, and management presentation. Both need to be aligned on the company's financial position and prepared for detailed questioning during management presentations.
