Checklist for Due Diligence in Company Sales

Before a company is sold, buyers want to know exactly what they’re getting into. This checklist provides a comprehensive overview of all documents and information that are examined during due diligence – legal, financial, business, and technological.
The list appears frighteningly long. Prepare the documents early. A structured due diligence not only increases the chances of sale but also the selling price – through transparency, trust, and minimized risk for the buyer.
With this checklist, you keep track and ensure that your company is ready for inspection – clear, complete, and convincing.
