Tech Stack Audit: How to Find $30k+ in Annual Savings
A tech stack audit inventories every SaaS tool, integration, and manual workaround in your business, then identifies redundancy, underutilisation, and broken data flows. The average Australian SMB with 30+ tools finds $30k–$80k in annual savings from consolidation alone, before counting the operational efficiency gains.
If you can't list every SaaS tool your business pays for, what each one costs, and how many people actually use it, you need a tech stack audit. This isn't optional housekeeping. It's a financial exercise, and it pays.
Step 1: Build a complete inventory. Pull subscription data from your accounting system, credit card statements, and IT admin consoles. Include everything: project management, communication, CRM, analytics, design, HR, finance. Most businesses discover 20–40% more tools than they expected.
Step 2: Map utilisation. For each tool, document: how many licenses are paid for, how many people actively use it, which features are actually used, and whether the tool has overlap with another. Ask team leads directly. Dashboard login data tells part of the story, but actual usage patterns tell the rest.
Step 3: Map integrations and data flows. Draw how data moves between systems. Where are the manual steps? Where do people export from one tool and import to another? These manual bridges are both cost centres and error sources.
Step 4: Score and prioritise. For each tool, assign a keep/merge/replace/kill recommendation. The quick wins are tools that duplicate functionality (kill the more expensive one), tools with <30% utilisation (downgrade or replace), and integrations that require manual intervention (automate or consolidate).
Frequently Asked Questions
Annually at minimum. Quarterly reviews of SaaS spend (just the financial data, not a full audit) catch new tool sprawl early. A full audit is warranted after any major business change: acquisition, rapid hiring, or new product launch.
Involve team leads in the audit process. When they see the cost data and the manual workarounds mapped out, resistance usually shifts to enthusiasm. Focus on what they gain (less context-switching, better data) not what they lose.
Yes, but an external audit catches blind spots. Internal teams often have attachment to tools they chose or built workflows around. An external auditor brings pattern recognition from dozens of similar businesses and vendor-neutral recommendations.
