Why stacking 7 tools costs more than an integrated solution
7 tools in your stack? Here’s what it costs
You’ve carefully selected the best CRM on the market. Added the project management tool that everyone recommends. Opted for the best-rated time tracking solution. And topped it all off with an invoicing tool, a collaboration platform, reporting software and, of course, a few handy spreadsheets for special cases.
In short, you’ve built the perfect stack. The best in each category. A logical approach, don’t you think?
Except that this best-of-breed strategy hides a far less attractive reality. Beyond the monthly subscriptions you religiously pay, there are invisible costs that can easily multiply your bill by three or even four. Between phantom licenses, evaporating productivity and hours spent on maintenance, your “optimized” stack could well be your biggest hidden expense.
Let’s take a look at what this stack oftools really costs you.
The addition of licenses is just the beginning
If you think that the cost of your tools is limited to the monthly invoices you receive, here’s the reality.
The weight of subscriptions
The figures speak for themselves. In 2024, the average company will spend $1,040 per employee per year on SaaS subscriptions alone, according to a Gartner study. For a 25-strong agency, that’s already $26,000 a year. And we’re talking about an average here.
The problem? This average masks an even more worrying reality: the average company uses 125 different SaaS applications. One hundred and twenty-five. Let that sink in for a second. Even for a medium-sized organization, we’re easily talking about 7 to 15 main tools that gradually accumulate. You start with a CRM, add a project management tool, then a billing tool… and before you know it, the stack has exploded.
Phantom licenses put a strain on the budget
Here’s the kicker: companies are only using 49% of their provisioned licenses. In other words, you’re paying for more than half of the empty seats.
According to Zylo’s SaaS Management Index 2024, which analyzes over 30 million licenses and $34 billion in SaaS spending, companies waste an average of $18 million a year on unused licenses. Even if your agency doesn’t reach these figures, the principle remains the same on your scale.
In concrete terms, these phantom licenses come from :
- Employees who have left and whose access has been deleted
- Completed projects requiring temporary tools
- Trial periods turned into forgotten subscriptions
- Function changes where old tools remain active
A quick audit of your current licenses is likely to yield some unpleasant surprises.
Expensive redundancy
Now let’s talk about redundancy, that discreet but costly scourge. According to the same Zylo study, the average company has :
- 11 project management tools
- 10 team collaboration applications
- 15 online training platforms
In a typical agency, we often find this absurd configuration:
- A time tracking tool to keep track of time spent
- A project management tool to organize tasks
- A planning tool to manage resources
- Spreadsheets to manage project budgets
- A billing tool that asks for some of the same information again
The result? Five different tools that do partially the same thing, with multiple double entries and no coherent overview.
| Type of cost | Average amount | Source |
| SaaS expenditure per employee/year | 1 040 $ | Gartner 2024 |
| Waste of unused licenses | 18M/year (average company) | Zylo 2024 |
| Percentage of licenses actually used | 49% | Zylo 2024 |
| Average number of redundant tools | 11 (project management only) | Zylo 2024 |
The invisible cost of lost productivity
But the bill doesn’t stop there. The real cost lies in what your teams are NOT doing because of that scattered stack. And this is where the figures become truly alarming.
Context switching: the silent productivity killer
Imagine this scenario: your project manager consults the CRM to check customer information, switches to the project management tool to update a task, opens his time tracking tool to enter his time, then checks the spreadsheet to see if the project budget still stands. Four different applications for a single coherent action.
This constant to-and-fro between applications has a name: context switching. And it literally massacres your teams’ productivity.
The data speak for themselves. According to the Anatomy of Work Index, workers switch between 9 different applications on average every day. Some studies even show that developers switch tasks 13 times an hour, spending just 6 minutes on one task before switching to the next.
The cost? Context switching can reduce productivity by up to 40%. This isn’t a wild guess; it’s the result of multiple converging research studies, including one by the American Psychological Association, which shows that adults who regularly switch between tasks have significantly lower overall productivity.
Let’s translate that into hard-earned euros:
- For an employee who costs your organization €70,000 – €80,000 a year
- Recovering evenone hour of focus per day represents around €9,000 – €10,000 in annual production value.
- On a team of 20 people, €180,000 – €200,000 of production capacity is lost.
And that’s just one hour a day. For many teams juggling 7 or more tools, the actual loss is far greater.
Cognitive recharge time
Here’s another chilling figure: according to research by the University of California at Irvine, it takes an average of 23 minutes and 15 seconds to regain full concentration after an interruption. Some studies even extend this estimate to 25 minutes.
Think about it for a moment. Twenty-three minutes to regain your flow state after each change of context.
The typical scenario in an agency with a split stack:
- You work on a sales proposal (concentration required)
- Notification: a customer has replied in CRM → you switch over
- You answer, then you have to update the schedule → new tool
- Meanwhile, a question arrives on your billing tool
- Open your reporting tool to check a KPI
- You finally come back to your proposal… 23 minutes later
Recent research shows that a worker undergoes an average of 12 contextual changes in 30 minutes during active periods. With 23 minutes to recharge each time, it’s easy to see why 40% of productive time evaporates.
For an 8-hour day, that’s around 3 hours of lost productivity every day. Every day. For every employee.
The psychological and human cost
Beyond the raw productivity figures, context switching has a measurable and documented human impact.
45% of workers say they feel less productive because of constant juggling between applications, according to Cornell University’s Workgeist Report. And 43% say that frequently switching between tools and contexts is “very tiring” mentally.
A study at the University of California, Irvine, measured the psychological state of participants after just 20 minutes of repeated interruptions. The result: a significant increase in stress, frustration, perceived workload and pressure.
But your teams experience this all day, every day.
What are the medium-term consequences?
- Increased cognitive fatigue and risk of burnout
- Increased turnover (and associated recruitment/training costs)
- More frequent errors due to fragmented attention
- Reduced quality of service for your customers
An Atlassian report estimates that context switching costs the global economy around $450 billion a year. This astronomical figure reflects the scale of the problem on a global scale. For your agency, even if we’re talking “only” about a few tens or hundreds of thousands of euros, the impact on competitiveness is real and immediate.
Integration and maintenance costs
And there’s more to come. Every new tool in your stack creates friction, which is costly, but tends to be underestimated, if not completely forgotten.
Integration debt
“We’ll connect everything together later.” This is probably the most dangerous phrase uttered in modern agencies.
Reality? ” Later” never happens. Or under conditions so degraded that the result is worse than the initial problem.
Direct consequence:
- Double manual data entry: the same information entered in the CRM, then in the project management tool, then in the invoicing system
- Intermediate spreadsheet files to bridge the gap between two incompatible systems
- Weekly exports/imports carried out manually by an employee who wastes 2-3 hours a week on this task
- Exponential risk of error: every manual recopy is an opportunity to make a mistake
Time spent on these “computer plumbing” tasks? Easily 5 to 10 hours a week for an average team. That’s 250 to 500 hours a year that create absolutely no value for your customers.
The cost of training
Each tool added to your stack represents a new learning curve for your teams.
The impact is manifold:
- Initial training multiplied: training a team in 7 tools takes 7 times longer (often with 7 different trainers or tutorials).
- Extended onboarding: each new recruit must master the entire stack before becoming fully operational.
- Continuous updates: each tool evolves at its own pace, with its own interface changes and new features
Let’s take the concrete example of a new project manager joining your agency:
- With 7 tools: 1 to 2 weeks training, continuous training for 1-2 months, reduced productivity during this period
- With 1 integrated platform: 2-3 days’ training, operational in less than a week
What’s the difference? Around 6 to 8 weeks of productivity saved over the first year.
For a project manager who costs €60,000 a year, that’s around €7,000 in lost productivity just on onboarding.
Time-consuming hidden maintenance
Then there’s all that invisible maintenance time that silently accumulates:
Renewal management :
- 7 tools = 7 different renewal dates to follow
- 7 potential business negotiations
- 7 invoices to check and validate
- 7 risks of unwanted automatic renewal
Access and permissions management :
- 7 authentication systems to manage
- Create and delete accounts in each tool for each HR movement
- 7 different security policies to maintain
- 7 times greater risk of breach if a former employee retains access
Technical support and assistance :
- 7 different contacts in the event of a problem
- 7 help centers with their own logic
- 7 community forums to check out
- No global vision for cross-functional problems
Updates and compatibility :
- Each tool evolves independently
- Risks of incompatibility between versions
- Tests required for each major update
In total, for a person in charge of the operational management of your stack (often an IT or ops manager, or even a CFO), you can easily count on 5 to 10 hours per month of pure administrative work. Over the course of a year, this represents 60 to 120 hours devoted solely to keeping the stack afloat.
With an hourly rate of €60-80, we’re looking at €4,800 to €9,600 a year just in administrative maintenance time.
When the stack becomes a strategic brake
Beyond the euros and hours lost, a fragmented stack deprives you of a crucial competitive advantage: the ability to pilot your business in real time and react rapidly to opportunities.
The fragmented vision that costs opportunities
The fundamental problem with a dispersed stack? Your data is scattered in 7 different places, with no coherent overview.
The consequences are direct:
Impossible to see in real time
- Your sales data are in the CRM
- Project progress in the project management tool
- Financial data are in your accounting tool
- The resource schedule is… somewhere in a spreadsheet
- Result: no consolidated view of your business at any given time
Tedious, manual reporting
- At the end of each month, someone spends 1-2 days consolidating data from 7 different sources
- Dashboards are obsolete by the time they’re ready
- Consolidation errors are common
Decisions based on incomplete or obsolete data
- “We think project X is profitable, but we don’t have the latest figures.”
- “We’d have to check the team’s availability, but it’s complicated to cross-check.”
- “I don’t know exactly where we stand on our objectives for the quarter”.
Missed opportunities
- A potential customer asks if you can start a project next week: impossible to answer quickly without spending 2 hours checking 4 different tools
- You don’t detect when a project is going off course financially until it’s too late.
- Unable to quickly identify your most profitable activities and develop them further
Agility sacrificed on the altar of complexity
In a fast-moving market, the ability to pivot quickly is a major competitive advantage. A fragmented stack takes it away.
Longer reaction times
- Each decision requires consultation and cross-checking of several sources
- Processes are fixed because they depend on the complex articulation between several tools
- Modifying a process involves reviewing the logic of 5 or 6 tools
Difficulty adapting your offer
- Would you like to launch a new type of service?
- The first thing to check is whether your 7 tools can support this new workflow
- Then adapt the configuration in each
- Train teams in these new configurations using 7 different tools
- Estimated time: several weeks, even months
Vs. with an integrated platform :
- Centralized configuration of the new project type
- Unique training on the new process
- Can be deployed in a matter of days
The difference between seizing a market opportunity or passing it on to a more agile competitor.
Shadow IT: the cost you don’t even see
Now let’s talk about an insidious phenomenon: Shadow IT, i.e. the tools your employees use without your knowledge.
The figures are staggering: according to Zylo, more than a third of the applications used in companies are Shadow IT. And 67% of IT managers cite the purchase of unauthorized tools as one of their main challenges.
Why do your teams do this? Often because your official stack is so cumbersome and fragmented that they’re looking for workarounds to be efficient. “I use this personal to-do tool because our official tool is too complicated.” “I pay for a little SaaS out of my own pocket because it saves me 2 hours a week.”
The risks are many:
- Data security: your customer information circulates in unsecured tools
- RGPD compliance: you no longer control where personal data is stored
- Unchecked costs: subscriptions paid for by employees are nowhere to be seen
- Individual dependence: the day this employee leaves, no one knows how to retrieve the data.
Shadow IT is often the symptom of an overly complex official stack. And it adds yet another layer of hidden costs and risks.
The real calculation: how much does your stack REALLY cost?
Now let’s do the math. Here’s how to estimate the real cost of your software infrastructure, beyond simple monthly subscriptions.
4-step calculation methodology
1.Direct costs (the visible part)
- Total monthly subscriptions × 12 months
- Multiplied by the number of licenses per tool
- Added unused licenses (around 51% according to studies)
For an agency of 20 people with 7 tools at ~25 €/user/month on average :
- 7 tools × €25 × 20 users × 12 months = €42,000/year
But with 51% waste: real cost for effective use = ~85,000 €/year
2. Productivity costs (the hidden bomb)
- Time lost in context switching: 40% of an hour per day minimum
- Multiplied by your employees’ hourly rate
- Multiplied by the number of employees
- Multiplied by 220 working days
For a team of 20 people at an average cost of €60,000/year (i.e. ~€35/hr):
- 1h/day × €35/h × 20 people × 220 days = €154,000/year in evaporated productivity
And we remain conservative with only 1 hour lost per day.
3. Maintenance and training costs
- IT/ops admin time: 5-10h/month
- Initial training per tool × number of tools
- Support and troubleshooting
- Time to consolidate data for reporting
Estimate for a medium-sized agency :
- Administrative maintenance: 8h/month × €70/h × 12 = €6,720
- Ongoing training and onboarding: ~€8,000/year
- Total: approximately €15,000/year
4. Opportunity costs (the most difficult to quantify)
- Manual vs. automated reporting: time spent
- Delayed decisions: missed opportunities
- Projects not launched for lack of visibility
- Customers lost through lack of responsiveness
It’s hard to put a precise figure on it, but a single contract lost at €50,000 because you couldn’t respond quickly enough about your team’s availability is enough to ruin the year.
The sobering final calculation
Let’s take our example of a 20-person agency with 7 tools:
Actual annual cost of an exploded stack :
- Licenses (with wastage): €85,000
- Lost productivity (1h/day): €154,000
- Maintenance and training: €15,000
- Opportunity costs (conservative): €30,000
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
TOTAL COST: €284,000/year
Integrated solution :
- Cost of all-in-one platform: €50,000/year
- Productivity gain (75% of 154k): €115,000
- Maintenance savings (70%): €10,000
- Better responsiveness: opportunities seized
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
NET SAVINGS: ~€209,000/year
You read that right: for a 20-strong agency, the difference can amount to over €200,000 a year.
And these figures are conservative. Many agencies discover, when they do the exercise honestly, that their stack costs them even more.
Before Furious, we had several tools managed by division, but they were complex to manage. With Furious, we standardized everything with a dedicated tool for the agencies. It’s really been a game changer for internal communication and team productivity.

The integrated solution: ROI calculated in weeks
Faced with this reality, more and more agencies are opting for consolidation. And feedback shows that it’s not just a question of costs, but of overall performance.
Immediate benefits
From the very first month of migration to an integrated solution, the benefits are tangible:
One subscription instead of 7
- A single monthly invoice
- Only one annual renewal to manage
- Unique commercial negotiation
- Immediate administrative simplification
A single training course for the whole team
- Single learning curve
- Centralized documentation
- Rapid skills upgrading
- Accelerated onboarding of new recruits
A single point of contact for support
- No need to play ping-pong between 7 different supports
- Faster resolution of cross-functional problems
- A true partnership is possible
- Unique product roadmap to follow
Unified real-time data
- Consolidated view of your entire business
- Automatic, up-to-date dashboards
- Ability to make informed decisions quickly
- Early detection of problems and opportunities
Rapid return on investment
Studies on the ROI of integrated solutions show encouraging results. According to an analysis by WPForms (2024), the average ROI of an integrated CRM is achieved in 13 months. And that’s for a simple CRM, not a complete all-in-one solution.
For an all-in-one agency management platform, the typical timeline looks like this:
Month 1-2: Immediate savings
- Eliminate redundant licenses
- Stop unnecessary subscriptions
- First visible savings at the end of the first month
Month 3-4: Productivity gains
- Teams master the platform
- Context switching is drastically reduced
- The first productivity gains are becoming measurable
- Reporting becomes automatic
Month 6: Balance point
- Investment in migration pays for itself
- Optimized processes
- The learning curve is behind you
Month 12: Solid positive ROI
- All profits are realized
- Cumulative savings far exceed initial investment
- Your agency is more agile and competitive
To take our example of a 20-strong agency saving ~€209,000 a year, the ROI becomes positive as early as 3ᵉ months if the investment in migration and training is €50,000.
Long-term, game-changing gains
More than just financial ROI, an integrated solution transforms the way you work:
Simplified scalability
- Add a new user = one click, not 7 configurations
- Developing a new offer = setting up a workflow, not reinventing the wheel
- Grow from 20 to 50 people without your stack becoming unmanageable
Rediscovered agility
- Unified processes = ability to pivot quickly
- Faster response to calls for tender (all info in one place)
- Launch new services in days, not weeks
Real-time visibility
- Continuous activity monitoring
- Anticipating problems before they become critical
- Rapid identification of growth opportunities
- Decision-making based on fresh, reliable data
Increased competitiveness
- Free up your time and resources to focus on your core business
- Ability to respond faster than your competitors
- Improved customer experience (responsiveness, follow-up, transparency)
- Less tired, more committed teams
Things to remember
Stacking up 7 tools to “choose the best in each category” sounds logical on paper. In reality, it’s a strategy that can cost you 3 to 4 times more than the sum of simple subscriptions.
Between phantom licenses, productivity evaporated by context switching, time swallowed up in maintenance and integration, and missed opportunities due to lack of visibility, the real cost can easily reach €250,000 to €350,000 per year for a team of 20 people.
The real question is no longer “Can I afford to invest in an integrated solution?” but rather“Can I afford NOT to?”
In a market where every point of margin counts, where responsiveness is a decisive competitive advantage, and where the well-being of teams has a direct impact on their performance, continuing to pile up tools is like throwing money down the drain.
Consolidation is no longer a comfort option. It’s a strategic necessity to remain competitive.

Youmay be asking yourself
these questions.
01 On average, how many tools does an agency use?
A medium-sized agency (15-50 people) generally uses between 7 and 15 main tools to manage its business: CRM, project management, time tracking, invoicing, accounting, collaboration, reporting, etc. To these are often added secondary tools and Shadow IT (tools used by employees without official validation). To these are often added secondary tools and Shadow IT (tools used by employees without official validation). Studies show that the average company, across all sectors, uses a total of 125 SaaS applications.
02 How do I identify unused licenses in my stack?
There are a number of ways to do this: ask each tool for a license usage report (most SaaS products offer this feature), perform a monthly audit of the latest connections per user, cross-reference the list of licenses with your current organization chart to identify departed collaborators, and survey your teams directly on the tools they actually use on a daily basis. You can also use SaaS Management platforms that automate this detection. On average, 51% of provisioned licenses are not used, or are used only to a limited extent.
03 Isn’t an integrated solution more risky (everything in the same basket)?
This is a legitimate fear, but the reality shows the opposite. With 7 different tools, you have 7 potential points of failure, 7 security policies to maintain, 7 risks of breach, and no overall vision in the event of a problem. A quality integrated platform generally offers enhanced security (only one system to secure, but better), centralized backups, a single, clear SLA, and a dedicated support team. What’s more, modern solutions use robust cloud infrastructures with redundancy. The real risk is to have a system so complex that no one can really control its security.
04 How can I convince my team to give up their favorite tools?
Change is always a challenge. The key is to start from the day-to-day problems experienced by teams: time wasted looking for information in 7 different places, frustrating double entries, the impossibility of getting an overview. Involve your teams right from the start of the selection process, have them test the integrated solution beforehand, and show them in concrete terms how their daily lives will be simplified. Identify “champions” in each team who can evangelize the solution. And above all: support the change with high-quality training. Resistance drops drastically when people understand that the new tool will really save them time.
05 What is a realistic timeframe for migrating to an integrated solution?
For an agency of 15-30 people, you should generally allow 2-3 months for a well-prepared migration: 2-3 weeks of scoping and preparation (process mapping, data cleansing), 3-4 weeks of parameterization and data migration, 2-3 weeks of training and support for teams, then 3-4 weeks of running-in with close support. The trick is to proceed gradually: start with a pilot department, validate that everything is working, then roll out to the rest of the organization. Some agencies opt for a “big bang” migration during an off-peak period (August, end of year), while others prefer a more gradual approach over 4-6 months. The most important thing is not to neglect the training phase: this is what guarantees adoption.
