Once the Heads of Terms are agreed, the Due Diligence (“DD”) process begins. This is where the buyer takes a detailed look beneath the surface of the business – financials, tax, commercial contracts, employees, legal matters, technology, customers…the list goes on.

For sellers, this stage is often the most intense. DD requires substantial input from the sellers and key staff, including finance teams, HR, and operations many of whom may not directly benefit from the sale and must keep the process confidential.

Preparing these teams early is essential. It is common for businesses to reward staff who play a major role in supporting the transaction through bonuses or other incentives.

Professional advisers are equally critical. They help coordinate responses, manage specialist DD streams, ensure accuracy and consistency, and protect your position during the process.

A well managed DD process reduces friction, keeps the deal moving, and helps minimise lastminute price adjustments.

Working alongside your lawyers, PEM’s deal specialists can manage and respond to DD enquiries, identify risk areas early, and help you prepare your business effectively if you are considering a future sale.
