How to Audit SaaS Spending

A practical process for finding unused licenses and duplicate tools.

SaaS spending tends to grow quietly. A team signs up for a tool on a corporate card, another department buys a similar product, and licenses keep renewing long after the project ends. Without regular audits, organizations routinely pay for duplicate, unused, or oversized subscriptions.

A structured audit surfaces these problems, gives you facts for renewal negotiations, and helps you align software spending with actual business value.

Step 1: Build a complete inventory

You cannot manage what you cannot see. Start by collecting every SaaS application that is being paid for, including expenses on corporate cards, invoices from vendors, and charges buried in cloud marketplaces.

  • Pull accounts payable and card transaction data for the last 12 months
  • Ask department heads for tools their teams use
  • Check single sign-on logs and identity provider application assignments
  • Review cloud marketplaces for subscriptions provisioned through AWS, Google, or Microsoft

Step 2: Map owners and use cases

Every application should have a named business owner. Without ownership, renewals happen on autopilot and no one is accountable for value. For each tool, record:

  • The department or team that requested it
  • The business problem it solves
  • Whether it overlaps with another tool already in use
  • The number of provisioned, active, and engaged users

Step 3: Identify waste

Waste usually falls into a few predictable categories. Look for each one in your inventory.

  • Unused licenses: users who are provisioned but have not logged in recently
  • Duplicate tools: two or more products solving the same problem across teams
  • Oversized tiers: premium plans where standard or lower tiers would suffice
  • Zombie subscriptions: recurring charges for projects or employees that no longer exist

Step 4: Take action and set a rhythm

An audit is only useful if it leads to action. Prioritize the largest contracts and the clearest waste. Cancel or downgrade tools that no longer justify their cost, consolidate duplicates where one tool can serve multiple teams, and renegotiate renewals based on actual usage data.

Set a recurring review cycle. Quarterly checks work well for fast-growing organizations; twice a year is sufficient for more stable environments. The key is making SaaS visibility a habit, not a one-time project.
