How to Perform a Proper Audit of Your Marketing Technology Stack

In today’s digital-first world, marketing teams often rely on dozens of different technologies — from CRMs and automation platforms to analytics, AI tools, content systems, and more. As stacks grow, they often become inefficient: tools overlap, integrations fail, and value is left on the table. Conducting a structured audit of your martech stack enables you to regain clarity, reduce waste, and realign your technology to support your business goals.

At Digital Practice, we view a martech audit not as a one-time exercise, but as a strategic process integral to long-term growth, operational efficiency, and data-driven decision-making.

Why a Martech Stack Audit Is Critical

It is no longer enough to simply collect tools. According to Gartner, marketers currently utilize just 42 percent of the capabilities of their martech stack. Gartner
This sharply underlines how much potential value is being left unused.

Meanwhile, the martech landscape is expanding at an unprecedented rate. There are now more than 14,100 marketing technology products, according to the 2024 Martech Landscape, representing a 27.8 percent growth year over year. Harro+1
With that many options, it is easy for organizations to accumulate overlapping or low-utility tools.

Beyond wasted spend, the risk of fragmented systems and data silos grows as stacks become more complex. According to research by G2, 51 percent of marketers say that integration challenges have hindered them from adopting new tech. G2 Learning Hub
An audit helps you uncover these inefficiencies and build a more cohesive and effective infrastructure.

Lastly, tool adoption is not always effective. According to Selling Simplified Insights (citing Gartner), only 58 percent of an organization’s martech capabilities are actually used. Foundry
That means nearly half of your stack might be underutilized — which is why a review is so important.

Step One: Inventory Every Tool You Use

To begin, you must map out every single marketing tool and platform currently in your environment. This includes marketing, sales, customer success and any other functions that contribute to customer engagement.

Your inventory should include:

In 2025, the State of Your Stack survey found that 68.6 percent of companies are already using generative AI tools in their martech stack. MarTech
Identifying these emerging tools in your stack early helps you understand where future spend may be going, especially if adoption is growing quickly.

Step Two: Evaluate Usage and Adoption

Once you know what tools you have, the next step is to assess how effectively they are being used.

According to a G2 survey, although marketing departments may subscribe to many tools, weekly active usage is often low. Their data shows that many marketers with 10 or more tools only use five or fewer tools each week. G2 Learning Hub
This underutilization often represents wasted budget and missed opportunity.

In addition, Gartner’s research shows that utilization of martech capabilities has declined: in 2022, marketers reported only 42 percent usage of their tool capabilities, down from 58 percent in 2020. Gartner
Reasons include overlapping functionality, lack of training, and complexity of the ecosystem.

To evaluate usage:

  1. Look at internal metrics (login frequency, feature usage, team engagement)
  2. Interview your teams to understand whether they feel the tools help or hinder
  3. Identify licenses that are rarely used or features that go unused
  4. Assess whether teams are trained and empowered to get the most from each tool

This diagnostic step helps you understand adoption barriers and decide where to invest in training, consolidation or retirement.

Step Three: Map Integrations and Data Flow

A powerful marketing stack is not just a collection of tools, but an interconnected system with clean data flowing between platforms. Without integration, you may have silos, manual handoffs, or unreliable reporting.

Research supports how critical this is: G2’s survey data shows that seamless integrations are now mission critical for marketers. G2 Learning Hub
Meanwhile, fragmentation remains a big issue: The Digital Bloom report found that about 65.7 percent of B2B marketers cite data integration difficulties in their stacks. Predictable Growth Agency

Your audit should examine:

By mapping your data pipelines, you can identify disconnects, eliminate manual work, and improve the accuracy of performance measurement.

Step Four: Evaluate Performance Against Business Objectives

Technology should support your strategic goals, not just sit in the background. In this step, you assess each tool’s impact on the business.

Consider key business objectives — for instance: lead generation, customer retention, customer experience, revenue acceleration, automation efficiency — and gauge how each tool contributes. You might ask:

According to Ascend2’s “Future of the Martech Stack” survey, only 34 percent of marketers believe their stack is very successful at helping them achieve strategic goals, while 59 percent say it is only somewhat successful. Ascend2
This indicates that many organizations are not fully leveraging their martech to drive business impact.

Step Five: Analyze Total Cost and Contract Terms

A detailed cost review is essential to understand ROI and uncover waste. Start by aggregating subscription costs, license fees, data usage charges, and support costs.

Gartner research highlights that underutilization is a common issue — many organizations invest heavily but reap only a fraction of the value. Gartner
Meanwhile, a report from Selling Simplified Insights estimates that only 58 percent of martech capability is actually used by most companies. Foundry
That gap represents potential savings or optimization.

During the audit:

This cost analysis is fundamental to making informed decisions about which tools to keep, which to renegotiate, and which to retire.

Step Six: Identify Gaps, Redundancies, and Opportunities

Now that you understand your tool inventory, usage, integrations, business alignment, and cost, you can identify where your stack is underperforming and where you can improve.

During this phase, look for:

According to the MarTech 2025 “State of Your Stack” report, 62.1 percent of marketers say they use more tools than they did two years ago, often driven by rapid AI adoption. MarTech
This growth creates both opportunity and risk; identifying where newer or homegrown tools add real value is a key outcome of the audit.

Step Seven: Develop a Roadmap and Governance Plan

Once you have clarity on what works, what does not, and what is missing, you can define a plan of action. Your roadmap should include short-term, mid-term, and long-term initiatives, along with ownership and governance.

Key elements of a strong action plan:

  1. Prioritized list of tools to retire, consolidate or expand
  2. Timeline for implementation, migration or decommissioning
  3. Updated process documentation and workflows
  4. Training plan for teams on optimized use of retained tools
  5. Governance framework to manage future purchases, integrations and training
  6. Metrics and KPIs to track success (cost savings, adoption improvements, data quality, business impact)

Without governance, martech audits may provide short-term clarity but fail to produce long-term change. At Digital Practice, we emphasize establishing a governance model that is both flexible and structured to adapt to evolving marketing strategies.
