# What is technical due diligence, and how should a company prepare?

Technical due diligence is the review investors, acquirers or large customers run on a company’s technology: how the system is built, who owns the code and accounts, how secure and scalable it is, and what it costs to run. Prepare by documenting the system, fixing quick wins and writing down known risks before they are found.

## What this means in practice

- Expect questions on architecture, code ownership, licences, security practice, data handling and costs.
- Make sure the company, not a vendor or individual, owns the code, domains and cloud accounts.
- Write down known risks with a dated plan; surprises cost more than disclosed issues.
- Have one person able to answer technical questions consistently and with evidence.

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.

## See it as a workflow

- [Technical due diligence preparation](https://lidvizion.ai/use-cases/technical-due-diligence-prep/): Get the technology, code and security story in order before investors or an acquirer ask, so diligence confirms the plan instead of derailing it.
