In today’s fast-paced world of mergers, acquisitions, and corporate investments, financial due diligence plays a critical role in supporting sound decision-making.

At Williamson & Croft, we recognise that behind every balance sheet and income statement lies a broader commercial narrative, one that needs to be carefully assessed before any deal is signed.

Appointing an experienced and commercially focused financial due diligence advisor at the earliest possible stage can be the difference between a smooth transaction and an expensive oversight.

In this article, we explore the value of appointing Williamson & Croft as your dedicated financial due diligence advisor and why our team should be your first call when a deal is on the horizon.

What Is Financial Due Diligence?

Financial due diligence is the process of reviewing and analysing a company’s financial affairs in detail to understand its true financial position.

This exercise provides critical insight for buyers, investors, lenders, or business partners, helping them make informed choices about the risks and opportunities attached to a transaction.

Typically, it includes analysis of:

  • Historical trading performance and profitability
  • The sustainability and quality of earnings
  • Working capital requirements
  • Tax compliance and liabilities
  • Off-balance-sheet risks
  • Forecast assumptions and key sensitivities

It is not simply a compliance exercise, it’s about building confidence, revealing hidden issues, and supporting negotiations.

Why appoint Williamson & Croft?

1. We focus on what matters commercially

At Williamson & Croft, our due diligence work goes beyond verifying numbers. We interpret the financial information within the commercial context of the deal. This means helping you answer key questions like: Is this business really generating sustainable profits? Are the reported margins credible? Could there be a future cash shortfall based on current working capital usage?

By cutting through complexity, we give you a clear view of the financial picture, and its implications for value, risk, and strategy.

2. We tailor our approach to your needs

Every deal is different. Whether you’re a private equity investor, an acquirer of an owner-managed business, or planning a strategic merger, we tailor our scope and deliverables to align with your objectives. We’ll work with you at the outset to understand what really matters. Whether it’s cash flow sustainability, exposure to contingent liabilities, or the strength of internal controls.

We’re used to working with a wide range of stakeholders, from legal teams and lenders to corporate finance advisors, ensuring our work fits seamlessly into the broader transaction process.

3. Seamless integration with tax & compliance advisory

Because our team includes tax and accounting specialists, we can offer integrated advice across areas such as:

  • Tax due diligence and exposure analysis (corporation tax, VAT, PAYE, R&D)
  • Capital allowances and property-related tax risks
  • Employment tax and off-payroll working compliance
  • Group structuring and post-deal tax planning

This joined-up approach ensures all financial and tax angles are considered, helping to reduce surprises post-deal and support value creation.

4. Partner-led delivery

At Williamson & Croft, our work is partner-led. This means you benefit from the direct involvement of senior professionals who bring real-world experience and judgment to every engagement. We’re responsive, proactive, and hands-on, something our clients consistently value.

Our due diligence process

Here’s what to expect when you engage us:

Initial Scoping
We take the time to understand your objectives, whether you’re buying, selling, investing, or refinancing. We’ll agree on the areas of focus and the depth of analysis needed.

Information Review
We request and review relevant financial and tax data, such as management accounts, statutory filings, working capital reports, tax returns, contracts, and forecasts.

Detailed Analysis
We analyse historical financials, normalise earnings, assess forecast assumptions, review key balance sheet items, and identify tax and compliance risks.

Reporting
We present our findings in a clear, structured report with executive summaries, detailed schedules, risk flags, and recommendations. We also provide verbal feedback and Q&A support to help you interpret the results.

Ongoing Support
Our support doesn’t end with the report. We’re on hand to advise during negotiations, assist with SPA drafting (e.g. warranty and indemnity input), and provide ongoing tax planning post-transaction.

Why timing matters

Too often, financial due diligence is treated as a box-ticking exercise, brought in too late in the process. Early-stage input from the right advisor can help shape the deal, from initial valuation and heads of terms through to negotiation of purchase price adjustments and post-deal planning.

By appointing Williamson & Croft early, you gain insight that could significantly alter the terms, or even your willingness to proceed. We give you the confidence to ask the right questions, challenge assumptions, and ultimately make better decisions.
