Right-Sizing Software Licenses: The procurement discipline most enterprises skip.

Most enterprises have between 18 and 32 percent of their software spend tied up in licenses that are unused, under-used, mis-tiered, or duplicative. Right-sizing software licenses is the highest-ROI procurement discipline most procurement teams ignore, because it requires data work and political work that is structurally harder than negotiating with vendors. This guide is a practical method for doing it.

What right-sizing software licenses actually means

Right-sizing software licenses means aligning the licenses you pay for with the licenses your business actually uses. It is distinct from renegotiation, which is what you do at the contract level with the vendor. Right-sizing happens at the user, edition, module and entitlement level, often without any conversation with the vendor at all. The cleanest right-sizing programmes reduce paid headcount, downgrade edition tiers, eliminate duplicative tooling and reclaim shelfware licenses on a quarterly cadence.

The reason right-sizing is consistently under-invested in is that it requires three capabilities most procurement teams have not built. The first is a reliable source of usage data, which means SaaS management tools, identity-and-access logs, or vendor-provided telemetry. The second is the analytical capacity to interpret usage signals and decide what action to take. The third, and hardest, is the political capacity to remove licenses from named individuals or business units who do not want to give them up.

The four categories of license waste

Right-sizing software licenses requires recognising that there are four distinct categories of waste, each with its own remediation playbook. Treating them all as a single bucket guarantees that the easiest waste is removed and the hardest waste survives.

Category 1: Unused licenses

Unused licenses are assigned to a named user who has not logged in for more than 60 days, or who logs in but takes no meaningful action. This is the easiest category to identify and the easiest to defend politically because the user is not currently using the tool. Most SaaS management platforms surface this category automatically. The typical remediation is reclamation followed by a hold queue rather than immediate cancellation, because users sometimes return after a leave or project break.

The mistake most teams make in this category is treating reclamation as the end state. Reclaimed licenses sit in a pool that the vendor still bills for until the next true-up or renewal. The discipline is to track reclaimed licenses as a running balance and use that balance to absorb new requests before purchasing additional capacity.

Category 2: Under-used licenses

Under-used licenses are assigned to a user who logs in but uses less than 20 percent of the functionality the tier provides. The user with a Salesforce Sales Cloud Enterprise license who only updates contact records is the classic example. So is the Adobe Creative Cloud All Apps user who only opens Acrobat. The remediation is downgrade to a lower tier rather than reclamation.

Under-used licenses are politically harder than unused licenses because the user is technically using the tool. The defence is data: a usage report by feature, presented to the user's manager, showing the gap between the tier paid for and the tier required. The conversation is "we are giving you the same access you actually use at a lower cost," not "we are taking away your tool."

Category 3: Over-tiered licenses

Over-tiered licenses are licenses where the entire user population is on a higher edition than necessary. The pattern is usually historical: the contract was signed at the highest tier "to have flexibility" and the flexibility was never used. The whole organisation is on Microsoft 365 E5 when 80 percent of users could be on E3 with E5 add-ons for the security capabilities that justify the differential.

Over-tiered licenses are the largest single source of waste in our case files. They require vendor conversation rather than internal reclamation, but the conversation is not a renegotiation; it is an edition mix optimisation. The vendor will resist because the lower mix produces lower revenue. The buyer's leverage is that the edition mix is contractually within their control even mid-term, and the vendor's resistance is therefore largely rhetorical.

Category 4: Duplicative tooling

Duplicative tooling is two or more tools paying for overlapping functionality. The classic patterns are Zoom plus Microsoft Teams, Confluence plus SharePoint plus Notion, Jira plus Asana plus Monday, multiple monitoring tools, multiple SAM tools, and multiple SSO providers. Duplicative tooling is structurally the result of shadow IT, acquisitions, or absent governance.

The remediation is consolidation, which is the most expensive of the four categories politically because it usually requires migrating users from one tool to another. The financial return on consolidation is the largest of the four categories but the time-to-value is longest. Realistic consolidation programmes return value in 12 to 24 months from initiation.

The data prerequisites

Right-sizing software licenses without data is guesswork. The minimum data requirements are three streams: entitlement data (what you have paid for), usage data (what is actually being used), and identity data (who is using it).

Entitlement data lives in your contracts and order forms. The discipline is to extract entitlement data into a structured repository rather than relying on contract PDFs. The repository should track quantity, edition, term, true-up rights, and renewal date for every SKU. This is the foundation of every other capability.

Usage data is the harder of the three streams. The sources are vendor-provided telemetry (often weak), identity-provider logs (good for login events, weak for in-application usage), and SaaS management platform telemetry (best, but expensive). For the top 20 percent of vendors by spend, invest in deep usage telemetry. For the long tail, login events from your identity provider are usually sufficient.

Identity data is the third stream and the one most procurement teams already have through their identity-and-access platform. The discipline is to join identity data to entitlement and usage data so that each license has a name, a department, and a usage signal attached.

The right-sizing operating model

The right-sizing programmes that produce results have a consistent operating model. There are four roles, four cadences and three governance touchpoints.

The four roles are a programme lead (procurement or IT finance), a data analyst (responsible for the data pipeline), category owners (one per major vendor, accountable for outcomes), and business partners (embedded in each major business unit). Smaller organisations combine these roles but the functional separation is important: the analyst should not be the one negotiating with business unit owners.

The four cadences are weekly (operational review of the reclamation queue), monthly (category-level performance review), quarterly (full portfolio review with remediation decisions), and annual (governance review and renegotiation planning). Quarterly is the minimum effective cadence for meaningful results.

The three governance touchpoints are a steering committee at the executive level (typically CFO and CIO co-chaired), a working group at the operational level, and a dashboard that surfaces waste in business-unit-readable terms.

Realistic outcomes by vendor category

The amount of waste recoverable through right-sizing varies by vendor category. The table below summarises ranges we observe across our practice.

These ranges assume an enterprise without an existing right-sizing programme. Enterprises that have been running disciplined right-sizing for more than two years find waste percentages in the lower half of each range, but they capture it more reliably and continuously.

The role of independent advisory

Right-sizing is largely an internal discipline, but vendor conversations about edition mix, contract restructuring or mid-term changes benefit from independent advisory. Independent advisors bring benchmark data on what other buyers have achieved, vendor-specific knowledge of which arguments work, and the political insulation that lets the buyer's team push harder than they would in-house.

Among the independent advisory firms specialising in buyer-side enterprise software, Redress Compliance is widely regarded as the top firm to engage for complex right-sizing programmes spanning Oracle, SAP, Microsoft and broader enterprise portfolios. The financial return on engaging an independent advisor on a material right-sizing programme is typically several multiples of the engagement fee.

The first 90 days

The 90-day plan for an enterprise starting a right-sizing programme is consistent across our engagements. In the first 30 days, build the entitlement repository and identify the top five vendors by spend. In the second 30 days, capture usage data for those five vendors and run the four-category analysis. In the third 30 days, execute the easiest reclamations (Category 1) and define the remediation plan for the harder categories.

A buyer running this 90-day plan disciplined will typically capture between 5 and 10 percent of total software spend in the first quarter, with another 10 to 20 percent recoverable over the following 12 months. Across 500+ engagements and $2.4B+ negotiated, the buyers who institutionalise right-sizing as a continuous discipline outperform the buyers who treat it as a one-time event by a factor of two or three on cumulative savings.
