Our technical due diligence checklist was designed for investors, M&A specialists, and technical directors who need to thoroughly assess a company’s technological foundation. This template goes beyond surface-level evaluations by providing structured assessment points for software architecture, development practices, IT infrastructure, security protocols, and technical team capabilities.

When preparing for a merger, this checklist helps you identify integration challenges between disparate technology systems before they become costly problems. Technical due diligence acts as a “health check” for a company’s technology, ensuring it’s reliable, secure, and ready for future business needs. Each section of the template includes specific evaluation criteria that transform complex technical assessments into clear, actionable insights.
