Cloud Budgeting Isn’t Complete Without SaaS Budgeting. Find Out Why

TL:DR: True Cloud Cost Control Requires SaaS Spend Visibility

• Cloud budgeting has long centered on infrastructure spend, covering compute, storage, and networking from providers like AWS, Azure, and Google Cloud, but must now incorporate SaaS to reflect how organizations actually spend.
• SaaS now represents a massive and largely uncontrolled share of total cloud spending, and most cloud budgeting strategies fail to account for it.
• Organizations that leave SaaS out of their cloud budgets risk hidden spend, tool sprawl, and reactive financial decisions at renewal time.
• Effective cloud budgeting requires both infrastructure cost management tools and SaaS management practices working in parallel, creating visibility, predictability, and shared accountability across all cloud spend.
• Zylo’s SaaS management platform gives IT, Finance, and Procurement teams the visibility and control they need to close the SaaS gap within any cloud budget.

Ask most IT or Finance leaders what they mean by “cloud budgeting,” and you’ll get a familiar answer: tracking compute, storage, and networking spend on AWS, Azure, or Google Cloud Platform.

That answer is correct. Managing cloud infrastructure costs is essential, and a thriving ecosystem of tools helps organizations do exactly that.

But that answer is no longer the complete picture.

SaaS has quietly become one of the largest and fastest-growing categories of cloud spend. Large enterprises now average $246M in annual SaaS spending, according to Zylo’s 2026 SaaS Management Index. Yet most cloud budgets treat SaaS as an afterthought, or don’t address it at all.

That gap is costing organizations millions.

The Traditional Definition of Cloud Budgeting and Why It’s Changing

Cloud budgeting started with infrastructure, but the definition has expanded significantly as SaaS has become a dominant share of enterprise software spending.

What Traditional Cloud Budgeting Covers

Cloud budgeting, in its original form, refers to the process of planning, monitoring, and controlling spending on cloud infrastructure. That includes resources like:

• Servers and compute instances
• Databases and storage volumes
• Data transfer and networking costs

The above resources run on platforms like Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

Tools purpose-built for this category, including AWS Cost Explorer, Azure Cost Management, CloudZero, and CloudBolt, give IT and engineering teams visibility into:

• Resource-level consumption
• Cost allocation by team or workload
• Optimization levers like reserved instances and rightsizing

This category of cloud budgeting is important, as infrastructure spend is significant, variable, and requires technical context to manage well. The FinOps Foundation has built an entire practice framework around it, and organizations with mature FinOps programs have demonstrated meaningful cost savings as a result.

How SaaS Has Changed the Cloud Budgeting Equation

When organizations moved workloads to the cloud, they also began buying software differently. Instead of purchasing on-premises licenses, teams started subscribing to cloud-delivered SaaS tools, including:

• Salesforce
• Workday
• Slack
• Zoom
• Microsoft 365

These aren’t infrastructure costs, but they are absolutely cloud spending.

SaaS now represents the single largest category of software spending for most enterprises, and it’s growing faster than ever. Our data shows that large enterprises with 10,000 or more employees spend an average of $246M on SaaS annually, with portfolio sizes averaging 696 applications.

That’s a staggering amount of cloud spending that falls entirely outside the scope of traditional infrastructure budgeting tools.

A cloud budget that only manages infrastructure can tell you what your servers cost, but not what your software costs. And in today’s environment, software is often the larger line item.

Why Comprehensive Cloud Budgeting Must Include Both Infrastructure and SaaS

Comprehensive cloud budgeting requires visibility into all cloud-based spending. Spending falls into two distinct categories, each with different purchasing patterns, stakeholders, and management tools:

• Infrastructure as a Service (IaaS): the compute, storage, and networking your engineering teams provision
• Software as a Service (SaaS): the software applications your entire organization subscribes to

While they cannot be managed by the same tool, they do need to be managed with the same rigor.

Each category has purpose-built solutions:

• IaaS: tools like AWS Cost Explorer, CloudZero, and CloudBolt are built for compute and storage costs
• SaaS: SaaS management platforms like Zylo are designed for software portfolios, licenses, and renewals

Together, they close the loop on cloud spending. Missing either half means your cloud budget has a blind spot.

The Real Cost of Ignoring SaaS in Your Cloud Budget

When SaaS is left out of the cloud budgeting conversation, the consequences are predictable and expensive. Here are the three most common failure points.

• Hidden spend and budget blind spots
• Tool sprawl and overlapping functionality
• Reactive decisions at renewal time

Hidden Spend and Budget Blind Spots

According to Zylo’s 2026 SaaS Management Index, IT is responsible for only 15% of SaaS spend. The remaining 85% of spend—driven by business units and individual employees—is a material blind spot where unknown spend quietly grows and drains budgets.

Today, organizations invest heavily in SaaS, with the average large enterprise spending $246M annually. Year over year, that’s a 16% increase in spend, while enterprise app counts grew just 8%. Vendor price increases, variable consumption models, and artificial intelligence act as hidden cost accelerators that further illustrate this growth—and the financial risk of SaaS.

In 2025, expense-based shadow IT spend grew 267%. Meanwhile, spending on AI-native applications skyrocketed nearly 400% for large enterprises. Shadow AI is widening the gap between what organizations believe is in use and what’s actually being adopted.

Without complete visibility into cloud-based software spend, budgeting accurately at scale will be fundamentally impossible.

Tool Sprawl and Overlapping Functionality

Decentralized software purchasing drives SaaS sprawl, the quick expansion of applications in enterprise portfolios. Each year, portfolios expand by 37% on average, contributing new tools to the stack—along with duplication and overlapping functionality.

With nearly 700 applications in the average enterprise stack, redundancy is inevitable. Multiple teams subscribe to different tools that perform the same function, whether that’s project management platforms, video conferencing tools, or design applications. Every redundant subscription is money that could be eliminated or consolidated.

Without visibility into the full SaaS portfolio, identifying and eliminating that waste is nearly impossible.

Reactive Decisions at Renewal Time

Infrastructure costs fluctuate month to month, while SaaS costs are locked into contract renewal dates that come once a year (unless multi-year). According to the 2026 SaaS Management Index, enterprises face an average of 467 SaaS renewals per year—roughly 41 per month or 2 per business day.

Each renewal is an opportunity to rightsize licenses, renegotiate pricing, or eliminate tools that no longer serve the business. But only if you know they’re coming.

Without a proactive renewal management process, teams are perpetually behind:

• Contracts auto-renew before anyone reviews usage
• License counts get locked in based on outdated headcounts
• Negotiating leverage disappears because you’re inside the renewal window before you realize it

The FinOps discipline of continuous cost monitoring makes sense for infrastructure, where spending fluctuates daily. SaaS requires a different rhythm, one built around contract timelines, renewal preparation, and proactive license reclamation. Without it, you’re budgeting reactively.

How SaaS Budgeting Complements FinOps

FinOps has become the gold standard for cloud infrastructure cost management, but its original scope wasn’t built to handle SaaS. Here’s where the two disciplines meet, and what happens when you connect them.

The Limits of FinOps for Managing SaaS Spend

FinOps was built for infrastructure, and that’s where its tools and workflows excel. When applied to SaaS, the gaps become clear. The differences are fundamental:

• Infrastructure costs are measured in compute units, data transfer, and resource hours
• SaaS costs are measured in licenses, contracts, renewal dates, and user entitlements
• Infrastructure budgeting requires continuous usage monitoring
• SaaS budgeting requires contract governance and renewal pipeline management

These distinctions mean that even a mature FinOps program can carry significant blind spots when it comes to managing SaaS spend.

To that end, the FinOps Foundation has recognized the need to expand. According to the 2025 State of FinOps report:

• SaaS is now the fastest-growing area of FinOps responsibility, with adoption projected to reach 65% of teams within the next 12 months
• 63% of FinOps practitioners now manage AI spend, more than double from the year prior

As SaaS pricing models shift from flat seat-based fees toward consumption-based and hybrid structures, the financial management challenges look increasingly similar to cloud infrastructure management. Usage spikes, variable billing, and AI add-on charges all introduce the kind of volatility FinOps was designed to handle, but SaaS requires its own purpose-built layer on top.

FinOps brings analytical rigor to the cloud spend conversation. SaaS Management brings the contract visibility, license governance, and renewal infrastructure that FinOps alone can’t provide.

Where FinOps and SaaS Management Intersect

The most forward-thinking enterprises are already connecting these disciplines. At The Home Depot, ITAM and FinOps were consolidated under a single leader to unify forecasting, governance, and spend management across both cloud infrastructure and SaaS, a model that our index data identifies as where the market is heading.

The two disciplines each bring something the other lacks:

• FinOps provides the framework for continuous cost awareness, consumption analysis, and accountability
• SaaS Management provides the system of record, a centralized inventory of every application, contract, license, and renewal date across the organization

As Ridge Fussell, Senior Manager of FinOps at The Home Depot, put it: “We saved a lot of money at renewal because we were able to see what we actually had, what we were using, and reduce license counts.”

That’s the advantage of SaaS Management in a single sentence: complete visibility that makes every renewal decision data-driven.

What Effective SaaS Budgeting Looks Like in Practice

Getting SaaS into your cloud budgeting strategy requires building a parallel SaaS management capability that operates with equal discipline and feeds into the same financial planning process.

SaaS budgeting looks like:

• Establishing visibility across your entire SaaS portfolio
• Forecasting renewals rather than monthly usage
• Aligning licenses, contracts, and business plans
• Connecting SaaS budgets to hiring and growth forecasts

Establishing Visibility Across Your Entire SaaS Portfolio

Effective SaaS budgeting starts with discovery. You need to know what applications your organization has before you can budget for them intelligently.

This can be harder than it sounds. Because SaaS purchasing is decentralized, happening through IT procurement, business unit budgets, P-cards, and individual expense reports, no single source of truth typically exists. A SaaS Management Platform like Zylo solves this by ingesting data from financial systems, SSO, and expense platforms to create a complete, centralized SaaS inventory of every application in the portfolio.

With full portfolio visibility, you can:

• Identify redundant applications across teams and departments
• Surface unauthorized tools purchased outside formal procurement channels
• Understand the full scope of what you’re paying for and where spend is concentrated
• Establish a baseline for realistic budget planning and forecasting

That foundation is what makes any meaningful cloud budgeting conversation possible.

Forecasting Renewals Rather Than Monthly Usage

Infrastructure costs require daily or monthly monitoring because they fluctuate with usage. SaaS costs require a different forecasting model, one built around contract renewal dates.

Because SaaS savings only happen at renewal, your budget planning needs to map out what’s renewing when, and what each renewal opportunity is worth. With an average of 476 renewals per year at large enterprises, that’s a substantial pipeline of potential savings to manage proactively.

The most successful organizations begin renewal preparation at least 120 days in advance. Here’s the cadence that consistently drives results:

• 120 days out: validate whether the application should renew, confirm ownership, and assess redundancy
• 90 days out: execute license reclamation to determine actual license need
• 60 days out: benchmark pricing through commercial support or peer comparison to establish a fair-value position
• 30 to 45 days out: finalize a data-driven negotiation strategy with full context on usage, license levels, and pricing expectations

This cadence eliminates the reactive scramble and ensures you’re never caught by an auto-renewal you didn’t see coming.

Aligning Licenses, Contracts, and Business Plans

One of the most common and costly SaaS budgeting mistakes is planning license counts based on current headcount rather than actual usage, and then failing to adjust as the business evolves.

Roles change. Teams restructure. Applications get adopted by some departments and ignored by others. Without continuous license utilization data, organizations end up over-licensed across dozens of applications, paying for seats that no one uses. In fact, according to Zylo’s 2026 SaaS Management Index, 43% of licenses sit unused, driving $80.5M in wasted spend for enterprises annually.

Effective SaaS budgeting means aligning your license footprint to real usage and business plans. If you’re expanding headcount in one department, you need additional licenses. If you’re contracting or switching tools, you need to reclaim them before the next renewal. Getting that alignment right is how you convert license waste into budget savings. Zylo’s SaaS spend management capabilities make that alignment continuous rather than a once-a-year exercise.

Connecting SaaS Budgets to Hiring and Growth Forecasts

The most mature SaaS budgeting programs need to go beyond reacting to current usage data. They anticipate future needs, which requires connecting SaaS planning to HR and finance planning cycles.

Consider the questions that only get answered well when SaaS is treated as a first-class budget line item:

• When headcount is projected to grow by 200 in the next fiscal year, which SaaS licenses need to scale?
• When a merger or acquisition is on the horizon, what SaaS overlap needs to be rationalized?
• When a new product line launches, what software does it require?

These questions require SaaS to be planned proactively alongside infrastructure, headcount, and capital expenditures, rather than reconciled after the fact. Organizations that make this shift stop reacting to SaaS costs and start planning around them. For a deeper look at how IT leaders are approaching this shift, the CIO playbook for navigating cloud, SaaS, and AI covers the governance structures making this possible.

Ready to Close the Gap in Your Cloud Budget?

Cloud budgeting has always required discipline. What’s changed is the scope.

With SaaS representing hundreds of millions of dollars in annual spending at large enterprises, a cloud budget that stops at infrastructure is missing a growing share of total spend. The organizations with the most accurate cloud budgets treat SaaS with the same rigor they apply to infrastructure: building a complete inventory, tracking licenses against actual usage, and connecting software spending to business plans and headcount forecasts.
