The hidden cost of multi-vendor IT: Why consolidation delivers more value

Organizations often look at licensing costs when choosing IT tools, but the cheapest option upfront doesn’t always translate to long-term savings. Many companies that adopt a multi-vendor IT setup, mixing platforms like Google Workspace, Slack, and AWS quickly realize that the hidden costs of managing such environments outweigh the initial benefits.

What if I told you that your “cost-saving” IT decisions could be quietly draining your budget and slowing your team down?

Although multi-vendor setups seem flexible, they often create higher expenses, inefficiencies, and added complexity. The reality is that technology consolidation, particularly with Microsoft 365, offers a clearer path to cost optimization and productivity.

When “cheaper” becomes more expensive

Take the example of a mid-sized organization that chose Google Workspace over Microsoft 365, focusing solely on licensing costs. On paper, Google Workspace Business Starter appeared to save money at $6–7 per user per month compared to Microsoft 365 Business Basic at $6 per user.

But the reality was more complicated. Their technology stack soon looked like this:

• Google Workspace for productivity and collaboration
• Slack for internal communication, even though Google Chat was included in their license.
• AWS for cloud infrastructure
• Microsoft 365 expertise already exists within their workforce.

Instead of streamlining operations, this fragmented approach introduced redundancy, integration challenges, and unexpected costs.

The real cost of multi-vendor complexity

Research shows that multi-vendor IT environments come with significant hidden costs that go well beyond licensing fees. Organizations dealing with multiple platforms face 3 major challenges:

1. Margin Stacking and Overhead Burden

Every vendor in a multi-vendor setup adds their own margin; whether it’s for hardware, software licenses, cloud services, or ongoing maintenance. This “margin stacking” drives up total IT costs considerably.

As of 2025, the organization was paying:

• Google Workspace licensing: $6–7 per user, per month
• Slack subscription: $8.75 per user, per month (Pro plan)
• AWS cloud services: Variable, but typically higher than integrated solutions.
• Additional costs: Integration and management overhead across systems

The result? A much higher operational expenditure compared to a consolidated approach.

2. Integration Complexity and Support Challenges

With multiple vendors, integration becomes complicated and support issues multiply. When problems occur, IT teams often face delays as they juggle different providers to identify the root cause, resulting in lengthy resolution cycles across multiple support channels. On top of that, overlapping features frequently lead to duplicate payments, while ongoing maintenance across diverse platforms adds even more cost and complexity to daily operations.

3. Workforce Training and Adaptation Costs

Technology adoption is only effective if employees can use the tools efficiently. In this case, most of the workforce was already comfortable with Microsoft 365, but moving to Google Workspace and Slack created challenges:

• Many employees only used basic features: Gmail or Docs, while advanced tools (e.g., Google Chat, Drive) had low adoption.
• Google Sheets was widely used (70% adoption weekly): Other apps lagged behind in business-critical usage.
• Teams struggled to adjust workflows: In Slack and Google Chat, slowing overall productivity.

This meant extra investment in training and a longer ramp-up before productivity gains could be realized. By contrast, staying with Microsoft 365 typically leads to faster adoption, smoother workflows, and reduced training costs – ultimately saving both time and money.

Comparing vendor choices vs. business impact

While multi-vendor environments may seem flexible, they often create overlaps and inefficiencies that drive hidden costs. The table below highlights specific examples of these redundancies, the better-aligned alternatives, and the resulting business impact.

All of this highlights a clear truth: while multi-vendor IT may seem like a shortcut to savings, in reality, it often traps organizations in a cycle of redundancy, inefficiency, and higher long-term costs.

So, what’s the smarter alternative?

The Microsoft 365 consolidation advantage

Microsoft 365 offers a comprehensive solution to address the challenges of fragmented, multi-vendor environments by delivering integrated services on a single platform.

A Unified Feature Set

With Microsoft 365 Business Premium ($22 per user/month), organizations gain access to:

• The full Office suite (Word, Excel, PowerPoint, Outlook)
• Microsoft Teams for communication and collaboration
• 1TB of OneDrive storage per user
• Advanced security features, including threat protection.
• SharePoint for document management and team collaboration
• Power Platform integration for workflow automation and analytics

This end-t0-end suite eliminates the need for multiple vendors, reducing complexity and ensuring a seamless user experience.

Total cost of ownership: Why Microsoft 365 wins

Cost comparisons reveal why Microsoft 365 provides greater value:

Microsoft 365’s integrated suite eliminates the need for Slack, reduces licensing overlaps, and delivers stronger value at a predictable cost.

Beyond cost: The strategic benefits of consolidation

The real advantage of Microsoft 365 goes beyond saving money; it’s about simplicity, productivity, and future readiness.

Enhanced User Experience and Productivity
Since most employees already know how to use Office apps, adopting Microsoft 365 is much smoother. With over 345 million users worldwide, the platform fits naturally into existing workflows, helping teams work faster without extra training.

Simplified Management and Security
Using one platform instead of juggling multiple vendors make IT management far easier. Microsoft 365 brings everything together with advanced security, centralized user management through Azure Active Directory, and consistent compliance across all apps.

Scalability and Future-Readiness
Microsoft 365 grows with your business. Automatic updates, seamless integration between tools, and enterprise-grade reliability with 99.9% uptime keep organizations agile and prepared for the future.

Moving from a multi-vendor environment to Microsoft 365 takes planning, but with the right approach, organizations can make the transition smoothly and see results quickly.

Migration considerations and best practices

Comprehensive Assessment
The first step is understanding what you already use. Audit current tools, identify overlaps and redundant costs, and assess where employees may need training. This helps build a clear roadmap for migration.

Phased Migration Approach
Shifting everything at once can overwhelm teams. A phased plan works better starting with email migration from Google Workspace to Exchange Online, then moving communication from Slack to Microsoft Teams, and gradually introducing Azure services where they fit best.

Change Management
Even with familiar Office apps, employees still need guidance. Leverage existing Microsoft 365 expertise, provide targeted training on new features, and set clear timelines and success metrics to keep the transition on track.

And to implement this roadmap effectively, organizations need the guidance of an experienced partner who understands both strategy and execution.
