Why You Need a SaaS Inventory
A SaaS inventory is the foundation of effective software spend management. Without a complete, accurate list of every tool your organization uses, you cannot optimize costs, manage security, or make informed decisions about your software stack.
Yet surprisingly few companies maintain one. Surveys show that only 25% of companies have a complete inventory of their SaaS tools. The rest are managing their second-largest expense category essentially blind.
Building a SaaS inventory is not glamorous work, but it pays for itself many times over by enabling cost optimization, security improvements, and better governance.
What to Track for Each Tool
A useful SaaS inventory captures the following for every subscription:
Basic Information
- Tool name and vendor
- Category: What function does it serve? (project management, CRM, communication, design, etc.)
- URL for the tool's login page
- Owner: Who is the primary business owner responsible for this tool?
- IT admin: Who manages the technical administration?
Financial Information
- Monthly/annual cost (base subscription)
- Pricing model: per-seat, flat-rate, usage-based, tiered
- Current tier/plan
- Payment method: Which card or account pays for this?
- Contract type: Monthly, annual, multi-year
- Contract start date and renewal date
- Auto-renewal terms and notice period
Usage Information
- Number of licenses purchased
- Number of active users (logged in within the past 30 days)
- Key departments/teams that use the tool
- Critical dependency: Is this tool critical to any core business process?
Security and Compliance
- SSO integration: Is the tool connected to your identity provider?
- Data sensitivity: What type of company data does this tool access or store?
- Compliance certifications: SOC 2, GDPR compliance, HIPAA, etc.
- Data residency: Where is data stored geographically?
Where to Find Your SaaS Data
No single source captures everything. Plan to pull data from multiple places:
Financial Sources
- Corporate credit card statements (request 12 months of history)
- Accounts payable records and purchase orders
- Employee expense reports
- Bank statements for direct debit payments
IT Sources
- Identity provider (Okta, Azure AD, Google Workspace) connected applications list
- SSO dashboard showing all integrated tools
- MDM (Mobile Device Management) for mobile apps used for work
- Network monitoring tools that can detect SaaS traffic
- Browser extension data showing tool usage
People Sources
- Department heads and team leads (survey them about tools their teams use)
- IT help desk tickets (common tools appear in support requests)
- New employee onboarding lists (what tools do you provision for new hires?)
Building Your Inventory: Step by Step
- Start with financial data: Pull all software charges from the past 12 months. This gives you the cost baseline and catches every paid tool.
- Cross-reference with IT data: Match financial entries against your identity provider and SSO data. This adds tools that might be on free tiers or paid for personally.
- Survey employees: Send a brief survey asking each employee to list the tools they use for work. This catches tools that bypass both finance and IT.
- Consolidate and deduplicate: Merge data from all sources, remove duplicates, and create a single master list.
- Enrich the data: For each tool, fill in the tracking fields described above (cost, users, contract details, etc.).
- Categorize: Assign each tool to a functional category. This enables you to spot duplicate tools easily.
- Validate: Share the inventory with department heads for review and correction.
Maintaining Your Inventory
An inventory is only valuable if it stays current. Set up processes to maintain accuracy:
Ongoing Updates
- Require the procurement process to update the inventory when any tool is added or removed
- Schedule monthly checks against financial records to catch new charges
- Review and update usage data quarterly
- Update contract details when renewals are negotiated
Quarterly Reviews
- Check for tools with low utilization (below 50% of licenses active)
- Verify that ownership information is still accurate (especially after organizational changes)
- Review upcoming renewals and flag any that need attention
- Identify new duplicates that may have emerged
Automation Options
Manual inventory management works but does not scale. As your tool count grows, automation becomes essential:
- Spreadsheet-based: Suitable for companies with fewer than 30 tools. Low cost but high maintenance and prone to going stale.
- ITSM integration: Tools like ServiceNow can track software assets as part of broader IT service management. Moderate cost and effort.
- Dedicated SaaS management platform: Efficyon automates the entire process—discovery, categorization, usage tracking, cost analysis, and renewal management. This is the most efficient approach for companies serious about ongoing optimization.
Your SaaS inventory is not just an administrative exercise. It is the foundation that enables cost optimization, security management, and informed decision-making about your software stack. Start building yours today, and you will be surprised at what you find.
