How to Audit SaaS Costs: Cut 30-50% in One Month
Most IT teams are overspending on SaaS by 30-50% without realizing it. Real audit results: a 50-person company found a $50K/year Slack overspend (wrong plan), discovered Teams could replace Zoom for free (already on M365), and cut Datadog costs by 60% by switching to Dynatrace. Here's the exact audit checklist IT managers use to reclaim budget.
The Overspend Problem (And It's Bigger Than You Think)
The average mid-sized company (50–200 people) spends $500K–$2M annually on SaaS tools. Typical findings:
- Slack overspend: Companies pay $165K/year for Slack Pro when Teams (often free via M365) would work just as well. Real example: 100-person team on Slack Pro = $165K/yr; same team on Teams Essentials = $480/yr (99.7% savings).
- Datadog overspend: Datadog's per-product billing (separate charges for infra, APM, logs) means bills balloon 5–10x expected cost. Dynatrace's flat-rate model costs 60% less at the same scale.
- Per-seat licensing waste: Teams buy seats for managers, executives, and inactive users. A 50-person team might be paying for 70 seats (40% waste).
- Forgotten subscriptions: Enterprise discovery tools (Torii, Zylo) find an average of 40% "shadow IT" — tools no one realizes the company pays for.
The Audit Checklist (Do This in 30 Days)
Week 1: Discover What You're Actually Paying For
- Export all active subscriptions: From your finance system (NetSuite, QuickBooks, etc.) or directly from Stripe/credit card statements. List tool, plan tier, annual cost, and number of users.
- Use discovery tools (optional): Torii, Zylo, or Blissfully scan your company's cloud accounts, credit cards, and SSO to find "shadow IT" — tools your team bought that finance doesn't know about.
- Create a SaaS inventory:** Google Sheets with columns: Tool Name | Plan Tier | Cost/mo | Users | Annual Cost | Business Owner | Last Renewal | Contract End Date
- Audit your top 20 by cost: Focus on the 80/20 rule. Your top 20 tools likely account for 80%+ of spend.
Week 2: Benchmark Against Market Rates
- Check if you're on the right plan: Are you paying for 10 users when only 5 are active? Are you on a premium tier when basic would work?
- Real example: Company pays $800/mo for HubSpot Professional (10 users) but only 3 people use it. Downgrade to HubSpot Starter ($50/mo) + Zapier automation ($25/mo) = $900/yr instead of $9,600/yr (91% savings).
- Check for free/cheaper alternatives: Use PricePulse or similar tools to find if competitors offer 50–80% cost savings.
- Slack Pro $165K/yr → Teams (free or $480/yr if not on M365)
- Datadog $5K/mo → Dynatrace $1,500/mo (70% savings)
- Zoom $15K/yr → Teams/Google Meet (often free via Microsoft 365/Google Workspace)
- Check for bundle/consolidation opportunities: If you use Slack + Zoom + Email, could Microsoft 365 or Google Workspace replace multiple tools?
Week 3: Negotiate Volume Discounts
- Identify tools with high renewal dates: 30–60 days before renewal, sales teams are most willing to negotiate.
- Get quotes from competitors first: Use competitor pricing as leverage. Tell Slack: "We're evaluating Teams (4x cheaper) — what discount can you offer to keep us?"
- Typical discounts available:
- Salesforce: 10–20% for annual contracts, 15–30% for 2+ year commitments
- HubSpot: 10–15% for annual payment
- Datadog: 10–25% depending on spend level ($50K+/yr unlocks better rates)
- Stripe: 10–30% at $1M+/month processing volume (enterprise only)
- Consolidation deals: "If we move from 4 vendors to 2, can you offer 20% discount?" Often yes.
Week 4: Execute Savings
- Downgrade/cancel tools: If cheaper alternative exists, test it with one team first (2-4 week trial).
- Rightsize user counts: Remove inactive users from paid plans. Typical company has 20–30% unused seats.
- Consolidate where possible: Replace Slack + Zoom with Teams, replace Intercom + Freshdesk with Zendesk, etc.
- Set up quarterly reviews: PricePulse or similar tools monitor price increases. Review new alternatives every 90 days.
Real-World Audit Examples
Example 1: 50-Person SaaS Startup
Found: $50K/year Slack overspend
Issue: Team was on Slack Pro ($165K/yr) with 120 seats (but only 50 people). They were also on Microsoft 365 Business Basic, which includes Teams for free.
Action: Migrated to Teams Essentials ($4/user/mo). Cost: $2,400/yr vs $165K/yr.
Savings: $162,600/year
Example 2: 100-Person B2B Company
Found: $50K/year monitoring overspend
Issue: Using Datadog for infrastructure monitoring ($3K/mo). Competitor audit showed Dynatrace could do the same for $1K/mo.
Action: Switched to Dynatrace Pro ($1,200/mo). Negotiated annual contract for 15% discount.
Savings: $25,200/year
Example 3: 200-Person Enterprise
Found: $120K/year in unused/duplicate tools
Issues: Paying for 4 CRM tools (HubSpot, Salesforce, Zoho, Pipedrive), 3 project management tools (Asana, Monday, ClickUp), 2 video conferencing (Zoom, Webex).
Action: Consolidated to Salesforce (CRM) + Asana (project mgmt) + Microsoft Teams (video) after negotiating 20% discounts across all three.
Savings: $120K/year
Most Common Overspends (And How to Fix Them)
Slack ($165K/yr for large teams)
Alternative: Microsoft Teams (free if you have M365, $4/user/mo if not). Same features, 99% cheaper. Savings: $150K–$160K/year for 100-person team.
Datadog ($24K–$120K+/yr depending on usage)
Alternative: Dynatrace ($15K–$40K/yr at same scale). Flat-rate pricing prevents surprise bills. Savings: $10K–$80K/year.
Zoom ($15K–$50K/yr for large teams)
Alternative: Microsoft Teams or Google Meet (often free via M365/Google Workspace). Savings: $15K–$50K/year.
Salesforce per-seat licensing ($30K–$150K/yr)
Alternative: HubSpot at smaller scale (better all-in-one value), Pipedrive (50% cheaper), or Zoho (60% cheaper). Savings: $10K–$100K/year.
Tools to Help with the Audit
- PricePulse: Monitors pricing changes on 80+ SaaS tools, alerts when competitors raise or lower prices.
- Torii, Zylo, Blissfully: SaaS spend management platforms that discover shadow IT and optimize licenses ($2K–$12K/yr).
- Fintech SaaS: Spend stack aggregators (still developing in 2026).
- Spreadsheet: A Google Sheet with your inventory is 90% as good as paid tools.
After the Audit: Stay Ahead
- Quarterly reviews: Every 90 days, check if new alternatives emerged, competitors lowered prices, or your team's needs changed.
- Monitor price increases: Use tools like PricePulse to get alerts when tools raise prices. Timing renegotiations around price hikes gives you leverage.
- Rightsize seats annually: Inactive users accumulate. Quarterly seat audits prevent 20–30% waste.
- Consolidate on renewal dates: Plan for contract end dates 60 days out so you have time to migrate if switching.
