10 steps to optimize your SaaS costs

Organizations routinely waste ~40% of SaaS budget on redundancy and shelfware — while app counts grow ~18%/year. This guide sequences the work so finance, IT, and security pull in the same direction, starting with why SaaS spend discipline matters.

What you’ll implement (high level)

1. Build a complete SaaS inventory (including Shadow IT).
2. Measure real usage (not “we bought seats”).
3. Remove or reallocate waste (downgrades > cancellations when possible).
4. Centralize contracts and renewal dates (stop silent renewals).
5. Negotiate with usage evidence (facts beat narratives).
6. Automate monitoring with tools like Avanoo to catch drift early — including Shadow IT.

Step 1: Build a trustworthy SaaS inventory

Combine IdP (Okta, Microsoft Entra ID, Google Workspace) with finance (Spendesk, Pennylane, Payhawk) and browser telemetry for apps purchased on cards or used as freemium.

Shadow IT is why SSO-only inventories lie: employees will use ChatGPT or Claude because it solves an immediate problem.

Once discovered, classify tools by function and status: approved / under review / unsanctioned. That classification drives SaaS management priorities.

Capture contract and cost metadata

Record monthly/annual costs, modules, owners, and renewal + notice windows — ~89% of SaaS contracts auto-renew by default.

Category	What to store
Admin	Vendor, owner, department, approval status
Finance	Cost, payment method, invoice linkage
Contract	Start date, renewal date, notice period, uplift clauses
Usage	Seats bought vs active users, last login buckets

Step 2: Analyze usage and find duplicates

Segment users into power / casual / read-only patterns — but validate with business owners before pulling seats from tools with naturally bursty usage (e.g. recruiting, e-signature).

Find functional duplicates

Group apps by category (storage, PM, comms) and pick a standard. Example tension: Dropbox vs Google Drive vs Box — paying for two solves the same collaboration problem twice.

Category	Common duplicates	Action
Files	Dropbox vs Google Drive vs Box	Pick one standard
Projects	Asana vs Jira vs Monday	Standardize on one
Chat	Slack vs Teams	Decide consciously
E-sign	DocuSign vs Adobe Sign	Consolidate volume

Step 3: Remove waste (without breaking teams)

Start with leavers: SSO automation should revoke access broadly, but you still need a license reclamation practice for apps outside SSO.

Downgrade premium tiers when advanced modules aren’t used — most waste is wrong tier, not “wrong tool.”

Consolidation improves security too: fewer vendors means fewer data processors to assess — see CISO compliance patterns.

Step 4: Centralize contracts and renewal governance

Move from “spreadsheets owned by one hero” to a shared system: owners, renewal dates, price uplifts, seat counts, and exit clauses.

Avanoo helps teams centralize discovery and catch duplicates that finance-only systems miss — see the retail SaaS savings case.

Calendar renewals aggressively

Set alerts 30–90 days before renewal and before notice deadlines. Missed dates are how “one more year” happens at the worst pricing.

Step 5: Negotiate with data (and focus on top vendors)

Use active usage charts and feature adoption metrics — especially for expensive CRM / collaboration stacks. Apply the 80/20 rule: a small set of vendors usually drives most spend.

If list pricing is sticky, trade for case study participation, logo rights, or improved SLAs — not every win is a line-item discount.

Step 6: Monitor continuously (SaaS is never “done”)

Dashboards should track cost per active user, seat utilization, and month-over-month app sprawl. Pair metrics with quarterly business reviews.

Automation platforms like Avanoo connect SSO + finance + browser signals to detect Shadow IT and Shadow AI drift early — the same drift that quietly recreates waste after a “successful” audit.

"Avanoo gave us full visibility into SaaS and AI usage, strengthened security, and helped optimize costs effectively." — Pierre M., CIO (Big Four)

Conclusion

SaaS optimization is not a one-time project — it’s an operating cadence: inventory, measure, reclaim, centralize, negotiate, monitor. If you only do the first two steps, savings decay within a quarter.

Automation reduces the human tax of keeping the inventory true — which matters because auto-renew clauses and decentralized buying will otherwise undo your progress.

FAQs

We don’t have a reliable SaaS inventory — where do we start?

Start with invoices + IdP exports + top 20 vendors by spend. You’ll immediately find duplicates and obvious shelfware.

How do we detect Shadow IT without blocking teams?

Pair approved alternatives with guided discovery (nudges) and transparent policies — blocking alone pushes workarounds underground.

Which KPIs prove savings?

Track recovered seats, vendor consolidation count, renewal avoidance (auto-renew traps prevented), and YoY SaaS cost per employee.
