You just walked out of a meeting where your Chief Marketing Officer asked you why the return on investment for marketing is not changing even though you are spending more money on tools than you ever have before. You open up a spreadsheet. Start counting all the tools you are using. You have an email platform, a customer relationship management system, a social scheduling tool, search engine optimization software, a webinar tool, an analytics platform, lead enrichment, attribution software, content management and a paid ads dashboard. You stop counting at fourteen tools. Realize you really cannot remember what half of them do or when anyone last used them.
What do then? You audit your set of tools. Martech audits are very important for optimizing costs and better results.
That is the moment when most marketing teams need a martech stack audit to understand they need to take a look at all the marketing technology tools they are using. Martech takes up nearly 22% of total marketing spend and its dispersion across teams can make management challenging. The numbers show that this is a problem. According to a survey by Gartner in 2025 companies are only using 49% of the martech tools they pay for. This means that the average company is only using about half of the tools they are paying for. For a business that spends $500 a year on marketing technology, that is approx $190,000 wasted with nothing to show for it.
A proper martech stack audit is how you stop that bleeding. This guide will show you how to do this step, by step and then how to use what you learn to make a plan that will save money and make your marketing work better at the same time.
What a Martech Stack Audit Actually Is (And What It Is Not)?
A martech tools audit is a review of every tool in your marketing technology stack. It looks at what each tool does, how much it costs, how often people use it, how well it works with tools and if it really helps your business.
This is not something you can do in one afternoon by making a list of tools. It is also not about getting rid of tools to save money. The goal of a marketing technology stack audit is to get a picture of your tools so you can make good decisions about what to keep, what to get rid of, what to replace and what you still need.
A lot of teams do not do a marketing technology stack audit because it sounds like a lot of work and nobody wants to tell their boss that a tool they liked two years ago is not being used. Not doing the audit usually costs more money than doing it. The Digital Bloom found that a good audit can help you recover 15 to 30% of the money you waste on tools. That is a lot of money that you can save.
Step 1: Build a Complete Inventory of Your Marketing Technology Stack
You cannot review what you cannot see. The first step is to get all the tools out of peoples heads and into one place.
This sounds easy. It is not. In companies different teams pay for different tools from different budgets. The social media team has tools that the marketing team does not know about. The sales team uses a tool that does the thing as a tool the marketing team already pays for. Someone signed up for a trial a long time ago and never cancelled it when it started costing money.
Start by making a list of all the software tools that your company pays for. Ask your IT or finance team to help you because sometimes tools are bought with department money that the marketing team does not control. Then ask each team member what tools they use every day. You will probably find some tools that you did not know about.
Step 2: Score Each Tool in Your Martech Tools Audit
Now that you have a list of your martech tools the next thing to do is score each tool so you can compare them in a fair way. This means you will not just be listening to the person who talks the most in a meeting.
A good martech stack audit looks at four main things.
- Usage rate: How often do people actually use this tool? Some tools will give you information about how many people have logged in. Others will need you to ask around. If you have ten licenses for a tool and two people have used it in the last ninety days that is a problem with the martech tool.
- Feature utilization: Just looking at how people use a tool is not enough. A team might use a tool every day. They might only use one or two of its features. For example, research by SALESmanago in 2025 found that 99% of marketers do not use all the features of their marketing technology. Also 62% of marketers said they only use between 57% and 75% of the features. If you are paying for the expensive version of a tool but you are only using the basic features of the martech tool then you are probably wasting your money on the martech tool.
- Integration quality: How well does this tool work with all the tools in your marketing technology stack? A tool that does not work well with tools is a problem. It means someone on your team has to move data from one tool to another by hand, which takes a lot of time and can cause mistakes with the martech tool.
- Business impact: This is the thing to measure but it is the most important thing to consider for your martech tools. Can you see how this tool is helping your business, such as by increasing sales or revenue? If you really cannot see any connection between the tool and your business results after trying to find one that is a big warning sign for the martech tool.
Step 3: Identify Overlap and Redundancy
This is the part where we usually find the money in a martech stack audit. Overlap happens when two or more tools in our marketing technology stack do the thing. This is really common. We see it with analytics tools. Social media tools overlap too. Email and marketing automation platforms can also overlap.. Content tools overlap as well.
In 2024 and 2025 we saw a lot of tools come out for AI writing and content and this created a whole new layer of redundancy. This is because teams started using three or four of these tools without stopping to think about whether they needed them all. Research says that analytics, social management and content tools are the areas where we see the most redundancy in B2B marketing stacks.
Each of these areas usually has two to four tools that do things and we could probably get by with just one. So we need to go through our list of tools and group them by what they do not by what the people selling them say they do. Then we have to ask ourselves the question: if we could only keep one tool in this area, which one would we choose and why.
Sometimes the answer is easy to see. Times we need to take a closer look. It is always worth taking the time to think about it.
Step 4: Audit Your Integrations and Data Flows
A lot of martech optimization work comes down to fixing how tools talk to each other. If we have ten tools that work together they will usually do better than twenty tools that do not. So when we are looking at our integrations we need to check each pair of tools that should be sharing data.
We need to ask: is the connection working and how often does it update? Is it updating enough for what we need? Do the numbers match up on both sides?
For example if our CRM says we got 500 leads from a campaign. Our marketing automation platform says we got 430 then something is not working right. Marketing Mary’s framework did a report on integration audits. It said that when integrations fail it can cost us a lot of money. This is because our marketing team has to spend a lot of time fixing things that should happen automatically. We need to flag any integrations that are broken or not working right or giving us data. These need to be fixed before you can trust any of your reporting, and you cannot make good martech optimization decisions from reporting you do not trust.
Step 5: Calculate the Real Cost of Your Marketing Technology Stack
Now that you have a good idea of what you have and how well each tool is working you can get a better sense of what your marketing tools are really costing you.
This is not just about adding up how much you pay for each tool every month. The real cost also includes the time your staff spends managing each tool, the time it takes to train people, the cost of dealing with tools that do not work well together and the cost of missing out on things because you did not have the right information.
When you add all these costs up the total is usually a lot higher than you thought it would be. This is not a conversation to have but it is necessary because it helps make the case for making things better.
Step 6: Make A Plan To Improve Your Marketing Tools
This is where looking at your marketing tools turns into making them better. Based on what you found out in the steps you should now have a list of things to do.
There are all kinds of things to do.
- Cuts: these are tools that nobody uses or tools that do the same thing as another tool or tools that do not really help your business. You should cancel these tools soon as you can.
- Downgrades: these are tools where you pay for a lot of features but only use a few. You can save money by downgrading to a version or by negotiating a better deal.
- Integration fixes: these are tools that do not work together. You should fix the ones that’re most important to your work first.
- Training investments: these are tools that could be really useful but are not being used well because your team does not know how to use them. Sometimes the best thing to do is not to get rid of a tool but to teach your team how to use it.
- Replacement evaluations: these are tools that are not working well but are still important. You should look carefully at whether you should replace them.
- Fills: these are things your marketing tools are missing. You should only think about adding tools after you have dealt with all the other problems. Adding tools too soon just makes things worse.

How Often Should You Run a Martech Stack Audit?
The honest answer is that most teams do not do this enough. Research from The Digital Bloom found that 58 percent of organizations do a stack audit every year, which is a good starting point. However for teams that are growing fast or going through big changes it makes more sense to do a lighter review every six months.
The marketing technology landscape is changing all the time. New tools are coming out, old tools are getting features that make other tools unnecessary and the way teams use these tools is changing in ways that are not always easy to see. Doing a regular martech stack audit a simple one helps you avoid letting problems build up for years before someone finally decides to fix them.
The Difference Between a Martech Audit and Marketing Technology Optimization
Sometimes people use these two terms to mean the thing but they are actually different. A martech stack audit is like a checkup. It shows you what you have, how well it is working and where the problems are.
Martech optimization is what you do with the information you get from the audit. It is a process of making your marketing technology stack work better over time. This includes using the information from the audit to make changes, making sure different tools work together, training people to use the tools, creating ways to measure how well the tools are working and making sure you think carefully before adding or removing tools.
The audit is a project that has a beginning and an end. Martech optimization is something you need to keep doing all the time. You need to do both. They are not the same thing. One of the mistakes teams make is thinking that the audit will fix all their problems instead of using it as a starting point for ongoing optimization.
FAQ: Martech Stack Audit and Marketing Stack Management
What is the main goal of a martech stack audit?
The main goal is to get a clear and accurate picture of your entire marketing technology stack, what you have, what it costs, how well it is being used, and how well it connects. From that picture you can make real decisions about where you are wasting money, where performance is suffering, and what changes will actually move the needle. Most teams find significant savings in their first martech tools audit because nobody has looked at the full picture in one place before.
How long does a martech tools audit take?
It depends on the size of your stack. For a smaller team with 10 to 20 tools, a thorough audit can be done in two to three weeks. For enterprise marketing teams with 50 or more tools, it can take six to eight weeks to do properly. The inventory and scoring phases take the most time. The integration audit and optimization planning are faster once you have solid data to work from.
What is the difference between martech optimization and just cutting tools?
Cutting tools is one possible outcome of martech optimization, but it is not the whole thing. Martech optimization is the broader process of making your marketing technology stack work better. Sometimes that means cutting. Sometimes it means downgrading tiers. Sometimes it means fixing integrations, investing in training, or replacing a tool that is not performing well with one that fits better. Pure cost-cutting without a performance lens often ends up removing tools that teams actually needed, which causes a different set of problems.
How do you know when your marketing stack management needs a proper audit?
A few strong signals: your team regularly complains about not being able to trust the data, you have multiple tools doing similar things and nobody is sure which one is the “real” one, your martech spend has grown but results have not, you have had significant team turnover and nobody is sure who owns what, or it has been more than a year since anyone took a full look at the stack. Any one of those is a good enough reason to start a martech stack audit now rather than waiting.
