SAM and ITAM are complementary disciplines of IT asset governance: SAM (Software Asset Management) controls software licenses, usage rights, and compliance, while ITAM (IT Asset Management) manages the entire lifecycle of hardware, software, cloud, and contracts. Integrated by a reliable CMDB, SAM and ITAM reduce waste and audit risk.<\/p>\n

SAM and ITAM: what each discipline covers<\/h2>\n

ITAM is the practice of registering, controlling, and optimizing all of an organization's IT assets, from purchase planning to disposal. This includes servers, laptops, networks, software, SaaS subscriptions, cloud resources, and the contracts that support each of them. The goal is to know what exists, how much it costs, who uses it, and what risk it represents.<\/p>\n

SAM is the ITAM subset dedicated to software. It compares what is installed or in use with what the company is entitled to use, i.e., usage rights, contracts, and licensing rules of each manufacturer. The result is a licensing position, which shows where there is excess (shelfware) and where there is exposure to audit penalties.<\/p>\n

In practice, SAM and ITAM answer different questions. ITAM asks "what assets do we have, where are they located, and how much do they cost over their lifetime?" SAM asks "are we using more, less, or exactly what we purchased?" Both questions depend on a reliable inventory, and that's where the disciplines intersect.<\/p>\n

Differences between SAM and ITAM<\/h2>\n

The key difference between SAM and ITAM is scope: ITAM covers all asset types and all phases of the lifecycle, while SAM delves deeper into the analysis of software licenses and usage rights. The table summarizes the most relevant differences for those who need to decide on investment priorities.<\/p>\n\n\n\n\n\n\n\n\n\n\n

There is also HAM (Hardware Asset Management), which deals with the hardware lifecycle and is also part of ITAM. Thus, ITAM functions as the umbrella discipline, and SAM and HAM are its two best-known branches. For a more in-depth look at SAM, it's worth reading the article about it. Reasons for implementing SAM<\/a>.<\/p>\n

Where SAM and ITAM overlap<\/h2>\n

SAM and ITAM share the same starting point: a complete and up-to-date inventory. Without knowing which devices exist and what is installed on them, ITAM cannot measure lifecycle cost and SAM cannot calculate licensing position. Therefore, both programs often fail for the same reason: data quality.<\/p>\n

Flexera's 2026 State of ITAM report indicates that only 361% of organizations have complete visibility into their assets and that only 311% have visibility into AI software.Flexera, 2026<\/a>; press release<\/a>The same study reports that 48% of organizations were audited in the last year, which shows that compliance pressure is real and recurring.<\/p>\n

The ISO\/IEC 19770-1:2017 standard establishes requirements for IT asset management systems and is the international process reference for those who want to structure ITAM in an auditable way.ISO<\/a>She doesn't prescribe tools, but rather practices that support both SAM and ITAM.<\/p>\n

How to integrate SAM and ITAM with CMDB and CSDM<\/h2>\n

Integration between SAM and ITAM occurs when both programs consume the same inventory, maintained in a... CMDB<\/a> Governed. The CMDB records the configuration items and their relationships, and the ITAM adds the financial and contractual context for each asset. SAM uses this set to reconcile installations and usage against vested rights.<\/p>\n

The CSDM (Common Service Data Model) completes the integration by linking assets and configuration items to business services and applications. This means that licensing costs are no longer a line item on a spreadsheet but become attributable to a service, allowing for renewal decisions based on usage and criticality. To understand the model, see the guide... CMDB implementation with CSDM in ServiceNow<\/a>.<\/p>\n

In ServiceNow, ITAM and SAM operate on the same platform and share the CMDB, which avoids parallel inventories. ServiceNow platform<\/a> It also allows for triggering workflows based on licensing data, such as initiating a reharvesting task when a license is not in use. 4MATT, a ServiceNow Elite Partner in Brazil with over 110 certified specialists, works on implementing these areas; its SAM practice was recognized in...

ROI of SAM and ITAM: how to calculate<\/h2>\n

The ROI of SAM and ITAM is calculated by comparing the investment in the program with the measurable benefits it generates, using a baseline defined before implementation. The formula is simple: ROI = (benefits \u2013 investment) \/ investment. The difficulty lies in defining which benefits are included in the calculation and how to measure them without double counting.<\/p>\n

The table below lists the most commonly used sources of benefit and the evidence required for each. Values should come from the organization's own historical data, not market averages.<\/p>\n\n\n\n\n\n\n\n\n\n
Source of benefit<\/th>\nHow to measure<\/th>\nRequired evidence<\/th>\n<\/tr>\n<\/thead>\n
Unused licenses deleted or redistributed<\/td>\nAnnual cost of recovered or non-renewed licenses<\/td>\nUsage versus rights report, before and after<\/td>\n<\/tr>\n

Operational hours saved<\/td>\nHours of manual inventory and reconciliation eliminated, multiplied by the hourly cost.<\/td>\nTime tracking before automation<\/td>\n<\/tr>\n
Underutilized or obsolete hardware<\/td>\nCost of assets recovered, reused, or disposed of within the timeframe.<\/td>\nInventory with life cycle<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

There are two useful benchmarks for sizing the potential. Flexera's 2022 State of ITAM report pointed to a waste of 38% of spending on desktop software, 34% on data centers, 33% on SaaS, and 33% on IaaS and PaaS (Flexera, 10\/2022<\/a>In 2016, Gartner stated that organizations can cut up to 30% from software costs with three SAM best practices (Gartner, July 19, 2016<\/a>These are research data with explicit dates, and not a promise of results for any company.<\/p>\n

For a defensible ROI from a financial standpoint, three precautions are helpful: record the baseline before any changes, count each savings only once, and separate realized benefits from projected benefits. SAM and ITAM programs typically deliver the first gains in renewals and audits, and operational efficiency gains appear as automation matures.<\/p>\n

Common mistakes when dealing with SAM and ITAM.<\/h2>\n

The most frequent mistake is implementing SAM and ITAM as separate projects, each with its own inventory. The result is conflicting numbers between teams and a licensing position that no one can audit. The solution is to start with a single inventory, maintained in the CMDB, and treat SAM as an analysis layer on top of it.<\/p>\n

The second mistake is measuring only the tool, and not the process. Without responsible parties, update routines, and indicators, the inventory loses quality in a few months. The third is ignoring cloud and SaaS, which today account for a large part of the spending and require collection through integration, not just through an installed agent.

Frequently asked questions about SAM and ITAM<\/h2>\n

What is the difference between SAM and ITAM?<\/h3>\n

ITAM manages all IT assets throughout their lifecycle, including hardware, software, cloud, and contracts. SAM is the software-focused subset of ITAM: it reconciles what is in use with licensing rights to ensure compliance and avoid unnecessary spending.<\/p>\n

Is SAM part of ITAM?<\/h3>\n

Yes. SAM is one of the disciplines of ITAM, alongside HAM (hardware). In many organizations, both are operated by the same team or the same set of processes, with shared inventory.<\/p>\n

Do I need a CMDB to have SAM and ITAM?<\/h3>\n

It's not mandatory, but it's what underpins the integration. A governed CMDB provides the inventory and relationships that SAM and ITAM consume, reduces parallel inventories, and allows linking license costs to business services through CSDM.<\/p>\n

How do you measure the ROI of SAM and ITAM?<\/h3>\n

Define a baseline before deployment and compare it to the measured benefits: recovered licenses, reduction in renewals, corrected audit exposure, operational hours saved, and assets reused. Apply the formula (benefits \u2013 investment) \/ investment, counting each saving only once.<\/p>\n

Which standard guides IT asset management?<\/h3>\n

ISO\/IEC 19770-1:2017 establishes requirements for IT asset management systems and is the international process reference. It defines practices, not tools, and can be used to structure both SAM and ITAM.<\/p>\n

Where to start a SAM and ITAM program?<\/h3>\n

Start with inventory: find out what exists, standardize the software by product and edition, and link each item to its contract. Then, prioritize the vendors with the highest spending and audit risk, and only then expand to cloud, SaaS, and other assets. To learn about the services approach, see the pages on...
