How to Audit and Cut Your Team's SaaS Spend

The average company spends 30% more on SaaS than it realizes. Tools added for specific projects never get cancelled. Free trials converted to paid without review. Tools that one team uses while another team has a duplicate covering the same function.

A SaaS audit is the systematic process of finding and eliminating this waste. Done once, it typically surfaces significant savings. Done on a regular cadence, it keeps the stack clean as the company grows.

Here's the step-by-step process.

Step 1: Build the Complete Inventory

The first step is also the hardest: getting a complete list of every tool your team pays for. SaaS subscriptions hide in three places:

Company credit cards: Pull 12 months of statements and look for recurring charges. Sort by vendor and amount. Anything with "monthly" or recurring billing is a candidate for the list.

Individual expensed tools: Employees who expense software subscriptions through their personal cards. Depending on your approval process, these may be well-documented or nearly invisible. Ask managers to survey their teams.

Annual contracts and enterprise agreements: These often don't show as monthly charges. Check with your CFO or finance team for any annual SaaS commitments.

Build a spreadsheet with: tool name, vendor, monthly cost (normalized to per-month even if billed annually), primary use case, team or department using it, contract renewal date, and who owns the relationship.

Getting this list complete is the hardest part of the audit. It's common to discover tools nobody remembers signing up for still billing the company card.

Step 2: Categorize by Usage

For each tool, categorize it:

Critical: The team couldn't function without this tool for a week. Core infrastructure.

Useful: People use this regularly and it makes work better, but there's a possible alternative or consolidation path.

Occasional: Used for specific projects or by a subset of the team. Worth questioning.

Unknown: Nobody is sure who uses this or why. Flag for investigation.

Unused: The subscription is active but usage is negligible or zero.

Getting real usage data is better than asking people. Most enterprise tools have admin dashboards showing active users and usage frequency. Pull these before the audit conversations — it's harder to justify a tool when the admin dashboard shows 3 of 20 licensed users logged in the last month.

Step 3: Identify Overlap

With a categorized inventory, look for functional overlap — two or more tools covering the same use case.

Common overlaps:

• Multiple project management tools (one team uses Asana, another uses Monday, a third uses Notion for project tracking)
• Duplicate communication tools (Slack for some teams, Teams for others, plus email)
• Both a dedicated time tracker and time tracking built into the project management tool
• Both a dedicated invoicing tool and invoicing capability in the accounting software

Overlap is expensive for two reasons: the direct cost (paying for two tools doing one job) and the integration cost (data that should be in one place is split, requiring manual reconciliation or automation).

For each overlap, identify the consolidation path: which tool wins? Which gets cancelled? How does data migrate?

Step 4: Apply the Sunset Criteria

For tools in the Unused and Unknown categories, the default decision should be cancellation, not investigation. If nobody can explain why the company is paying for it, stop paying for it.

For tools in the Occasional category, ask: is this worth the per-seat cost for the number of people who actually use it? A $15/seat tool with 20 seats, but only 5 people who log in regularly, is a $225/month cost for what is functionally a 5-seat tool. Either reduce to 5 seats, find a cheaper alternative, or cancel.

For tools in the Useful category with available alternatives or consolidation paths, do the cost comparison including switching cost. If consolidating from five tools to two saves $800/month but costs 40 hours of migration work at $75/hour (=$3,000), the payback period is under four months. Usually worth it.

Step 5: Calculate the Before and After

After completing steps 1–4, calculate:

Current monthly spend: Total of all tools in inventory

Target spend after consolidation: After cancellations, seat reductions, and tier downgrades

Annual savings: The difference × 12

Implementation cost: Migration time, data cleanup, onboarding to new tools

Payback period: Implementation cost ÷ monthly savings = months to recover

Present this calculation to whoever approves the changes. A well-documented audit with clear savings and a defined payback period is easy to approve.

The Template

Tool Inventory:
| Tool | Monthly cost | Users | Usage level | Category | Action |
|------|-------------|-------|-------------|----------|--------|
| [Tool] | $X | X of X | High/Med/Low/None | Critical/Useful/Occasional/Unused | Keep/Reduce/Cancel |

Summary:
Current monthly spend: $X
After changes: $Y
Monthly savings: $Z
Annual savings: $Z × 12

How Often to Repeat This

A one-time audit is valuable. A recurring practice is more valuable.

Suggested cadence:

Quarterly mini-audit: 30 minutes. Check for new tools added since the last audit, tools from completed projects that weren't cancelled, and seat counts that have drifted above actual headcount.

Annual full audit: 2–4 hours. Full inventory rebuild, usage data review, consolidation opportunities assessment. Align with annual budget cycle.

Event-triggered audit: Whenever you hire aggressively (tool seats may need adjustment), experience significant team structure changes, or before signing any new annual contract (check whether you already have overlap with existing tools).

The teams with the cleanest, most cost-efficient stacks aren't the ones that made all the right decisions upfront. They're the ones that review and prune regularly.

For a related perspective on why tool sprawl is so common and costs more than people realize, why your team has too many SaaS tools and why cheap SaaS tools often cost more than you think are worth reading alongside this audit process.
