The Hidden Cost of Choosing IT Vendors Without a Plan

Imagine an 85-person professional services firm running out of two offices. Last month, their internet connection went down. Three different vendors spent most of a day pointing fingers at each other before anyone made an attempt to solve the problem. The hardware reseller who handled the original office build-out said it wasn’t their equipment. The phone and network provider brought on when the second office opened said it wasn’t their line. The security vendor, added after a scare a couple years back, said their tool wasn’t involved either. As a result, solving the problem took longer than the actual fix required.

This hypothetical scenario illustrates a very important assumption that many businesses make: choosing a good vendor every time you need one eventually results in a good vendor setup overall.

As an IT provider that offers vendor advisory support, we have a clear reason to want you to think that vendor management is complicated. Instead, this article offers an honest look at exactly how and where ad hoc vendor decisions end up costing organizations like yours more than they appear to at first glance. This will show you what to check in your vendor setup, whether or not you ever bring in outside help.

Choosing a Vendor vs. Having a Vendor Strategy: Why They’re Not the Same Thing

Every vendor decision the firm made in our example passed a simple test. Did it solve the immediate problem in front of them? Was the price fair? Did the vendor show up and do the work? The hardware reseller delivered. The network provider got the second office online. The referral for cloud storage checked out. The security tool did what it promised. By that measure, they made good decisions.

But choosing well in a single moment and having a coherent overall setup are different skills. Think of it the way you’d think about furnishing a house one room at a time, with a different decorator for each room and no one ever stepping back to look at the whole house. Each room, taken alone, might look great. But the entire experience feels disjointed.

Adding vendors based on immediate needs doesn’t usually take into account whether a new vendor fits everything the business already has in place. This process doesn’t factor in whether a new purchase belongs next to what’s already there or works against it. A decision can clear the first test completely and still add friction the business doesn’t see for months.

This process can become even more difficult to manage when your IT stack becomes too unwieldy. Zylo found in its 2025 SaaS Management Index that even small organizations, those with 1 to 500 employees, run an average of 152 SaaS applications. That figure covers only software, not hardware, network, or phone vendors, but it illustrates how fast a vendor list grows even at modest scale, often faster than anyone is checking how the pieces fit together.

A vendor strategy is what makes an individual choice hold up over time, not just in the moment it’s made.

Five Ways Vendor Decisions Go Wrong Without a Plan

Paying Twice for the Same Capability

When nobody keeps a running list of what the business already has, it tends to create duplication. Maybe the Calgary office buys a backup tool with no idea that the Edmonton office already licensed something that does the same job. Or a marketing team signs up for a project management platform, not realizing operations switched to one that covers the same need months earlier. Each purchase looks reasonable in isolation, made by someone solving a problem quickly. But together, it means the business is paying twice (or more) for the same capability.

BetterCloud’s 2025 State of SaaS report and found that 33% of organizations had consolidated redundant apps or accounts in the past year. A third of the organizations that looked found overlap to cut. The other two-thirds either don’t have the overlap (unlikely in a growing business) or haven’t looked yet.

Vendor Lock-In with No Way Out

When your organization chooses a vendor without asking how hard it would be to leave, that can create a problem that stays invisible for years. At the time of signing, the questions that typically matter to most businesses are about price, features, and whether the vendor can do the job now. Downstream factors like data portability, contract terms, and migration cost rarely come up, because in the moment when you’re choosing a vendor, you’re not thinking about how it would be to drop them.

The cost shows up later: when your business outgrows a vendor, finds a better fit, or wants to renegotiate from a position of strength. You may discover your data lives in a format nothing else can read, the contract locks in another two years, or migrating means months of running two systems in parallel.  

No Integration Planning

If you simply select your vendors one at a time, each to solve the problem in front of the business at that moment, you won’t know whether they’ll work with what’s already in place. The result is a set of tools that can’t talk to each other. Someone on staff ends up manually doing the job that software should be doing: re-entering the same customer data in two systems, exporting a report from one platform to import into another, or reconciling numbers by hand because two systems that should agree don’t.

That labour cost never shows up as a line item, but as lost time that could have been directed towards meeting your critical goals. A business that would balk at an extra invoice for the same work each month absorbs this version without blinking, because it’s paid in hours instead of dollars.

No Clear Owner When Something Breaks

Remember our earlier example of the professional services firm whose internet connection failed?

In this scenario, let’s say a new security rule had been blocking traffic between hardware the reseller had installed and the line the network provider had added. The failure had crossed the boundary between three separate vendor relationships, and none of those vendors had ever been asked to own anything beyond their own piece.

It’s not that these vendors were intentionally shirking responsibility. Each one could reasonably point to their own system, note it was functioning, and conclude the problem sat elsewhere. They weren’t wrong within the narrow view of their own contract. It’s just that no one had a bird’s eye view of how the pieces of this company’s IT vendor management fit together. The business, meanwhile, ate an entire day of downtime while three vendors worked out among themselves whose job it was to look further.

Picking Technology Based on What You’ve Heard, Not What Fits

Often times, a business may hear about a technology, maybe from a competitor, a sales rep, or someone on staff who used it at a previous job and ask for that tool directly. But that might not always be the right approach.

Chad Cunningham, Director of Business Development at Ironclad TEK, has watched this pattern play out with customers directly. “What they ask for and what they need are sometimes two different things,” he says. “Sometimes a customer will come to you with a solution to their problem and ask if you can do this for them. But really the problem is solvable in a better way.”

The impact of a mismatch like this rarely shows up right away. It leads to overpaying for capability the business doesn’t use, or getting stuck with a tool that can’t quite do the job, sometimes for months before the workaround becomes its own ongoing cost, layered on top of whatever the tool cost to begin with.

This is why breadth of expertise during the vendor selection process is so important. Someone weighing a decision across networking, security, and software options, rather than evaluating a single requested brand in isolation, is in a position to catch the mismatch before it costs your business anything.

What Strategic Vendor Selection Actually Looks Like

For our example firm, addressing the issues in their IT vendor management wouldn’t necessarily mean starting over. Rather, they just need to adjust their approach going forward to following a clear strategy.

This means each new need gets checked against what’s already in place before anyone signs a new contract: does this use case require a new vendor, or does an existing one already cover it? Every new hardware, software and cloud solution will align with where the business is headed, not just the loudest pitch or the most familiar name.

The second critical part is that the full vendor list needs to be revisited on a schedule, not only when something breaks. In most cases, vendor management failures surface retroactively when something forces the issue: a duplicate discovered by accident, a migration attempted too late, an outage that crossed vendor lines. A periodic review catches the same problems before they cost your business time, money or opportunities.

Ultimately, the most effective vendor selection and procurement requires an IT department or an IT consultant that understands how you operate and understands the technology in depth. backed by a broad bench of technology vendor relationships. Making that kind of match well involves having access to a broad bench of technology vendor relationships, but as Cunningham puts it, it also takes current knowledge across a wide range of areas, not one specialty: “We’re bringing to bear network expertise, security expertise, desktop services expertise, Microsoft expertise, server expertise, backup expertise.”

The goal in this article is to help you recognize whether your vendor setup has grown complex enough to warrant a second look. Plenty of businesses are not at this stage yet. A business running one or two straightforward vendor relationships, with no overlap, no integration to worry about, and a clear line of accountability if something goes wrong, can be entirely fine managing that type of vendor setup on its own.  

Reasonable Decisions Don’t Add Up to a Strategy on Their Own

The assumption we opened with was that picking a good vendor every time adds up to a good vendor setup overall. Now it should be clear why strong IT vendor management doesn’t happen automatically. Each of our example firm’s vendors was an understandable choice at the time. None of them, added together, produced a business that could point to who owned an outage crossing vendor lines.

Most businesses only notice the cost of an uncoordinated vendor setup when something breaks, which is exactly what happened here.  That doesn’t have to be how you find out. You can run the check yourself: look at your own vendor list and ask where duplication, lock-in, integration gaps, or unclear ownership might already be sitting.

Frequently Asked Questions

What’s the difference between IT vendor management and just asking your IT provider for a recommendation?

A one-off recommendation answers the question in front of you: which tool is best for this specific need. Effective, strategic vendor advisory looks at the whole list of vendors your business already has, checks for overlap and gaps, and asks whether new decisions fit your overall goals, not just whether they solve today’s problem.

How many vendors is too many?

No fixed number applies across every business. The functional test is simpler: can someone name every vendor relationship the business has, and say clearly who owns each one? A business that can’t answer both quickly has more vendors than it can actively manage, whatever the count turns out to be.

Does vendor advisory cost extra on top of managed IT services?

This depends on the provider and the engagement. Some structure vendor selection support as part of an existing managed services or strategic IT relationship. Others bill it separately as project work. Ask directly rather than assuming either way, since providers structure this differently.

Is a vendor review worth it if we’re happy with our current vendors?

Being satisfied with each vendor individually and having a coordinated vendor setup are separate questions. The five patterns above (duplication, lock-in, integration gaps, unclear ownership, and mismatched fit) can all exist quietly even when every individual vendor is doing good work, and nobody has a complaint. A review adds visibility into the whole vendor list, not just each relationship taken one at a time.
