Three DIY Procurement Mistakes Smart Mid-Market Teams Keep Making
10/21/20263 min read


I want to be careful here. The people who make these mistakes are not careless. They are capable, busy professionals who have been asked to handle a specialist task on top of a full-time job. If anything, the mistakes show how reasonable the instincts are. They just tend to produce expensive outcomes.
After working with companies across the mid-market, I see the same three patterns over and over. Let me describe each one and what it costs.
Mistake One: Buying From Whoever Called First
It usually starts with a problem. The internet is slow, the phones are unreliable, a security alert has everyone on edge. Then, almost like clockwork, a salesperson calls. They are friendly, they understand the problem, and they have a solution ready. The relief of having an answer is powerful.
The trouble is that the first caller is rarely the best fit. They are simply the first caller. By the time you have signed, you have compared one option against nothing. A vendor-neutral process reverses that: you define the need first, then see several credible options, and the call becomes one input rather than the whole decision.
Mistake Two: Over-Relying on One Vendor's Account Rep
Account representatives are often knowledgeable, personable, and genuinely helpful. They are also, by role, focused on their own company's products. When you ask them about your whole environment, you get answers filtered through what they sell.
That is not dishonesty. It is perspective. A representative who sells networking will think about your problems as networking problems. One who sells security will see security problems. Neither can easily tell you when the best answer lies in a different category, or with a different provider. Over time, a single rep becomes your de facto advisor, with an incentive structure you cannot see.
Mistake Three: No One Is Auditing the Renewals
This one is the quietest and often the most expensive. Contracts get signed, filed, and forgotten. Years later, the renewal arrives with a higher price, an extended term, or a changed service level, and the notice window to object closed weeks ago.
Typical culprits include automatic renewals that need written notice 60 to 90 days ahead, annual escalators that compound, and quantities or tiers that no longer match what you actually use. None of it is hidden. It is simply in a document nobody has reread since the day it was signed.
Why These Mistakes Compound
Each mistake feeds the others. If you buy from the first caller, you rely on that vendor's rep, who then manages your renewals. The same party that sold you the service advises you on whether to keep it. It is a quiet conflict of interest built into the setup, even when everyone involved means well.
Over several years, a company can end up with a patchwork of overlapping services, uneven support, and prices that have drifted well above market, with no single person who can explain how it got that way.
What the Alternative Looks Like
Replacing these habits does not require a big project. It requires three changes. First, define the need before talking to vendors. Second, get comparable options from several providers across the market, not just the one in front of you. Third, assign an owner for every agreement, with a calendar of notice deadlines and a regular review of price and usage.
An advisor can do all three for you, and can keep doing them. But even if you never hire one, adopting these three habits will put you ahead of most buyers.
A Quick Self-Check
Try answering these without looking anything up. When does each of your major technology agreements renew? What is the notice window? Which of your providers did you compare against alternatives the last time you bought? Who in your company owns each contract?
If you can answer all four for your top five agreements, you are in better shape than most. If you cannot, that is useful information, and a good place to begin.
A Short Illustration
Picture a 180-person company whose internet went down twice in a month. A salesperson called the next morning with a faster plan. The IT manager, relieved, signed within a week. Later it turned out the outages came from an issue on the company's own side of the network, and the new plan, with a three-year term and annual increases, solved a problem the company did not have. This is a composite, not a specific client, but versions of it are common.
A slower process would have asked a different first question: what actually caused the outages? That question comes before any product, and it is the kind a neutral party is well placed to ask.
Why Smart People Fall Into This
These patterns are not about intelligence. They are about time and incentives. Your team is rewarded for keeping systems running, not for running a procurement process. Vendors, meanwhile, run sales processes every day and are very good at making the next step feel easy.
The remedy is not to distrust everyone. It is to put a small amount of structure around the decision so that urgency and familiarity do not make it for you.
The Bottom Line
These three mistakes are common, understandable, and fixable. If you would like a second set of eyes on your current agreements, Sigma Technology Consulting is happy to take a look as a vendor-neutral advisor.
