To reduce SaaS costs without taking away tools employees rely on, first build a dependable inventory of applications, owners, contracts, paid seats, actual usage, integrations, and data sensitivity. Then right-size licenses, test overlap before consolidating, and retire software only with a documented migration and access-revocation plan. A staged review—with business owners involved and productivity monitored—can reduce waste without treating low usage as proof that a tool has no value.
Why start with an inventory instead of a cancellation list?
A cancellation list built from invoices alone can miss tools bought on employee cards, applications accessed outside single sign-on (SSO), and software with seasonal or occasional use. The opposite problem is also common: a paid seat may remain assigned even when its user has left or no longer needs it. Neither the invoice nor a login count, by itself, tells you whether a service is safe to cut.
FinOps Foundation guidance treats SaaS discovery, inventory, data ingestion, monitoring, reporting, and value assessment as connected capabilities. Its 2024 summit polls found that about 70% of FinOps practitioners reported managing SaaS and about 65% reported managing licensing. In the Foundation’s 2025 survey, respondents represented organizations responsible for more than $69 billion in cloud spend; workload optimization and waste reduction was the top FinOps priority, 50% reported optimization remained a priority, and 63% reported managing AI spending. These are survey findings about FinOps practitioners and organizations, not a forecast of savings for an individual company.
What should a useful SaaS inventory contain?
Bring together finance, procurement, identity, IT, security, and the teams that use the applications. Reconcile different names for the same product, distinguish purchased seats from active users, and record where the information came from and when it was checked. Use browser or network discovery only where company policy and applicable privacy requirements permit it.

#1 Best Overall
| Inventory field | What to record | Why it matters |
|---|---|---|
| Application and supplier | Product name, supplier, edition or tier, and any duplicate or related product names | Helps identify overlapping subscriptions and match invoices or identity records to the right service. |
| Owners and users | Business owner, technical owner, department, seats purchased, seats assigned, active users, and the usage period checked | Creates a route for decisions and separates a license count from evidence of use. |
| Cost and contract | Invoice or procurement source, contract terms, renewal date, seat minimums, and known pricing changes | Shows when action is possible and helps prepare for renewal using actual usage rather than guesswork. |
| Workflow and value | Outcomes the application supports, critical tasks, peak or seasonal patterns, and the minimum workflow that must remain available | Prevents a low-frequency but essential process from being mistaken for waste. |
| Dependencies and data | Integrations, data classification, access method, and relevant business or technical dependencies | Surfaces the operational and information-security consequences of changing or retiring the service. |
| Purchase path | Whether the service came through procurement, an expense claim, a department budget, or another approved route | Reveals applications that a central contract list or invoice feed may not capture. |
Use finance invoices, procurement records, identity-provider and SSO logs, expense reports, permitted browser or network discovery, and user interviews as complementary inputs. Flag conflicting or missing records for an owner to resolve; do not silently treat missing usage data as proof that nobody needs the application.
How should you decide what to keep, reduce, consolidate, or retire?
Make decisions at the application and workflow level. For each candidate, compare total cost with active and peak use, business outcomes, support burden, risk findings, integrations, and the cost and effort of switching. Route the decision to the business owner and technical owner rather than relying on a single utilization threshold.
| Situation | Action to consider | Required safeguard |
|---|---|---|
| High business value or a critical workflow | Keep the service and protect the access, support, and resilience it needs. | Document its owner, required workflow, dependencies, and renewal evidence. |
| More paid seats or a higher tier than current needs justify | Right-size seats or evaluate a lower tier. | Check peak and seasonal use, feature dependencies, and team exceptions before changing access. |
| Two or more tools appear to overlap | Test whether one service can cover the necessary workflows before consolidating. | Compare integrations, data, task completion, and user requirements—not just product labels. |
| No active owner or apparent use | Investigate whether the service is abandoned, intermittently used, or still supports an essential process. | Confirm with affected teams, plan any data export, and revoke access in a controlled sequence before retirement. |
| A renewal is approaching | Renegotiate using verified seats, usage, outcomes, and contract requirements. | Start with the inventory and owner review early enough to make a considered decision before the renewal date. |
Low use is a prompt to investigate, not an automatic cancellation rule. A small number of users may maintain a critical control, handle a periodic reporting task, or need access only during a seasonal peak. Conversely, a popular tool is not automatically good value if its cost, risk, or duplicated capabilities outweigh its outcomes.

How can you make changes without disrupting work?
Use a controlled change plan rather than removing seats or switching products across the organization at once.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problems- Define the workflow that must survive. Ask the business owner and affected users to list essential tasks, integrations, data, permissions, and peak periods. Set a clear success measure, such as completing the required task or preserving a critical integration.
- Run a pilot. Test a proposed seat reduction, tier change, or replacement with a representative team. Include users whose work depends on unusual features or less frequent tasks.
- Prepare the move. Write a migration runbook covering communications, training or office hours, data export, access changes, support contacts, and a rollback path if the essential workflow fails.
- Stage the change. Make changes in phases and provide an exception route for teams that can show a legitimate business need, such as a peak or seasonal requirement.
- Check impact after each phase. Monitor task completion, adoption, support tickets, and incidents against the baseline. Pause or roll back if the change is harming a critical workflow or creating a material operational problem.
How do you prevent SaaS sprawl from returning?
Put a lightweight review in front of new purchases. The goal is not to make every request slow; it is to find an existing approved service, establish an owner, and identify cost and risk before a new contract or account becomes difficult to track.
- Ask what workflow or outcome the requester needs and whether an existing tool already covers it.
- Record the proposed business owner, technical owner, users, data involved, integrations, expected cost, and procurement route.
- Review security, privacy, access, data retention, supplier terms, and renewal conditions at a level proportionate to the service and information involved.
- Set an approval path and a place to store the decision, contract, and renewal date so the service enters the inventory when it is approved.
The U.S. Centers for Medicare & Medicaid Services’ SaaS Governance model describes tracking usage and evaluating products for authorization in a setting where customers have limited visibility into providers’ infrastructure and may face unexpected risk. That model supports making discovery and review part of intake, rather than trying to reconstruct the application portfolio only at renewal time.
Which supplier risks should a review cover?
For an application that handles company or customer information, ask the supplier and internal reviewers for evidence relevant to the service and its data. NIST guidance addresses third-party acquisition and software supply-chain risk, including software bills of materials (SBOMs), vendor-risk assessment, open-source controls, and vulnerability management. CISA’s Secure by Demand guidance recommends making security an explicit procurement requirement.
- Security practices: How does the supplier develop and update the software, manage vulnerabilities, and provide vulnerability-disclosure information?
- Access and incidents: What access controls are available, and what incident-notification commitments apply?
- Data handling: Where is data processed or stored, which subcontractors can access it, how long is it retained, and how can it be deleted?
- Resilience and exit: What evidence is available about service resilience, and can the organization export its data in a usable format when leaving?
- Assurance and commercial terms: What audit evidence can the supplier provide, and how can pricing, renewal terms, or seat requirements change?
Match the depth of review to the sensitivity of the data, the service’s importance, and the access it receives. Record unresolved risks with an accountable owner and a decision; a completed questionnaire alone does not make a risk disappear.
Can SaaS management or SSPM tools help?
SaaS spend-management platforms can help bring contracts, invoices, licenses, and usage into a more consistent view. SaaS security posture management (SSPM) tools can add API-connected visibility into application configuration, access, data protection, vulnerabilities, and compliance gaps. These tools can improve discovery and route findings, but they do not replace owners who decide what is valuable or who fix a problem.

When comparing options, test them against the same inventory and success measures. Consider:
- Discovery coverage, invoice and contract ingestion, and the granularity of seat and usage data.
- Identity and application API integrations, business-owner workflows, and renewal or approval controls.
- Security configuration checks, data-protection and compliance coverage, reporting, and data export.
- Implementation effort, portability and exit support, and total cost at the organization’s scale.
CMS reports using AppOmni for its SaaS governance and says onboarding eligible applications typically takes one to two weeks. That is CMS’s reported experience for eligible applications, not a general implementation estimate for other organizations or products.
What should happen at quarterly reviews and before renewal?
Review the portfolio at least quarterly and revisit each service before its renewal. Compare the current cost with active and peak usage, outcome measures, support burden, risk findings, integration dependencies, and switching costs. Record the evidence, decision, approver, and any follow-up action in the inventory. That record makes the next review faster and gives procurement a fact base for renewal or exit decisions.
