What does a useful tech stack audit include?

A tech stack audit should show where software is helping the business and where it is quietly creating cost, risk, or drag.

Direct answer

A useful tech stack audit reviews SaaS subscriptions, infrastructure, integrations, security posture, vendor overlap, data flows, ownership, reporting gaps, and the systems that create operational or delivery bottlenecks.

The business reason

Tool sprawl often grows unnoticed. Teams add software to solve local problems, but no one reviews the total system.

Balazs's Tech Snapshot

The Tech Snapshot is a fast audit designed to uncover redundant costs, security holes, integration bottlenecks, and quick-win optimisations.

The goal

The best result is not a bigger tool list. It is a smaller, clearer, safer stack that supports how the business works.
