Due diligence advice and reports

Corporate finance

Buy, sell, invest with confidence.

Whether you’re buying or selling a business, due diligence is a critical step to protect value and reduce risk. It establishes the accuracy of key information and supports better decision-making throughout the M&A process. At RSM, we deliver clear, thorough, and actionable due diligence reports. Our experienced team helps you understand the financial, operational, and tax risks of your transaction so you can move forward with confidence.

What our due diligence covers

Our financial due diligence is tailored to each deal but typically includes:

Detailed analysis of historic performance, quality of earning, cash flows, working capital needs and cash / debt.
Review of financial systems, controls, and tax positions.
Assessment of management forecasts and key operational risks.
Clear summaries of findings, risks, and recommendations.

We also highlight potential integration issues to support a smooth post-deal transition.

After the deal — supporting your next steps

We know the first 100 days post-acquisition are crucial. Our team stays with you to support smooth integration, provide ongoing financial and operational advice, and help with tasks such as bookkeeping, payroll, HR, and VAT compliance.
