How to Audit Your Martech Stack (And Stop Paying for Tools You Don't Use)
Marketing technology has a spending problem. The average marketing team uses 12 tools. Many of those tools overlap in functionality, integrate poorly with each other, and are used by only a fraction of the team. The result is a stack that costs more than it should, produces less than it could, and creates more friction than it removes.
A martech audit is the process of systematically evaluating your current stack, identifying what's working and what isn't, and building a leaner, more integrated set of tools that actually supports your marketing goals.
Step 1: Inventory Everything
The first step is simply listing every tool your marketing team uses — including tools that were set up years ago and are still being paid for even though no one remembers why. Pull your credit card statements and your team's app subscriptions. You'll almost certainly find tools you forgot you were paying for.
For each tool, document: what it does, who uses it, how often it's used, what it costs, and what it integrates with. This inventory is the foundation of everything that follows.
Step 2: Map to Marketing Functions
Once you have your inventory, map each tool to the marketing function it serves. A useful framework organizes martech into six functional categories:
| Function | Examples |
| Advertising & promotion | Google Ads, Meta Ads, LinkedIn Ads |
| Content & experience | CMS, landing page builders, video platforms |
| Social & relationships | Social scheduling, community management, CRM |
| Commerce & sales | E-commerce platform, payment processing, CPQ |
| Data & analytics | GA4, BI tools, attribution platforms |
| Management & operations | Project management, collaboration, reporting |
Step 3: Evaluate Integration Quality
A martech stack is only as good as its integrations. Tools that don't talk to each other create data silos, manual work, and attribution gaps. For each tool in your stack, evaluate: does it integrate natively with the other tools it needs to connect with? Are those integrations reliable? Are they being used?
Poor integration is often more costly than the tool subscription itself, because it creates hidden costs in manual data entry, reporting errors, and missed automation opportunities. Our Martech Stack Audit & Build service specifically evaluates integration quality as a core part of the audit.
Step 4: Score Each Tool
With your inventory, functional mapping, and integration assessment complete, score each tool on three dimensions: value delivered, usage, and integration quality. Tools that score low on all three are candidates for elimination. Tools that score high on value but low on usage are candidates for training. Tools that score high on value but low on integration are candidates for replacement.
Step 5: Design the Future Stack
The output of a martech audit isn't just a list of tools to cut — it's a blueprint for the stack you want to build. This blueprint should be driven by your marketing strategy and your automation goals, not by vendor relationships or historical inertia.
A well-designed martech stack has a clear "system of record" for each data type, clean integrations between tools, and a rationalized number of tools that your team can actually use well.
The ROI of a Leaner Stack
The ROI of a martech audit comes from two sources: direct cost savings from eliminating unused tools, and indirect value from better data quality, more automation, and less manual work. Most audits we conduct identify 20–30% cost savings.
