Why I Stopped Expecting One Vendor to Know Everything (And Why You Should Too)

I Used to Think a Big Name Meant Everything

When I took over purchasing for our 50-person company in 2020, I had a simple rule: go with well-known brands. If a name was familiar, it probably meant they were reliable. That logic cost me a $2,400 headache in my first year—and taught me a lesson I still use today.

The best suppliers aren't the ones who claim they can do everything. They're the ones who tell you clearly what they're not good at.

How I Got Burned by a Name

Our office needed a commercial cookie oven for employee events. I searched online, and there it was: Otis Spunkmeyer. I knew Otis from the elevators in our building—huge company, global reputation. I assumed the cookie oven company was part of the same group. The price was listed at around $2,800. I placed the order without asking too many questions.

Fast forward two weeks: we received a countertop oven that was clearly meant for a kiosk, not a 50-person office. Worse, the invoice had a different company name, and our finance team rejected it because the vendor wasn't pre-approved. I ended up paying $200 in restocking fees plus the cost of a proper oven from a different supplier. Total lost: nearly $400 out of my departmental budget.

Everything I'd read about procurement said to go with established brands. In practice, I found that a brand name in one category doesn't mean expertise in another. Otis Elevator and Otis Spunkmeyer share only a name—nothing else. One is a global elevator pioneer (founded in 1853); the other is a baked-goods supplier. They don't even operate in the same industry.

The Harrison Gray Otis House Incident

Around the same time, a colleague asked me if our elevator vendor (Otis) also managed the historic Harrison Gray Otis House in Boston. I didn't know the answer, so I called our Otis service rep. He laughed and said, “That's a historic house museum—nothing to do with our elevators.” The confusion happened because the house was built for a man named Harrison Gray Otis, who has no connection to the elevator company except sharing the last name.

That moment stuck with me. If even well-educated professionals can confuse a supplier's scope based on a name, how many procurement mistakes are happening every day?

When I Tried to Get Everything from One Vendor

After the cookie oven fiasco, I swung the other way: I decided to consolidate as many purchases as possible with a single supplier. Our building needed screen door replacement for three exits. I approached a large facilities vendor who claimed they could handle “everything from elevators to window screens.” Their quote was competitive, so I went ahead.

The screen doors arrived two weeks late, with the wrong mesh size. The vendor argued it was “standard.” We ended up keeping them because we needed something, but they've never fit properly. A year later, I called a specialized door-and-window company. They had the right product in stock and installed it in two days—for 30% less than the “one-stop” vendor.

The conventional wisdom is that one supplier is easier to manage. My experience with those 60–80 annual orders suggests that relationship consistency often beats marginal convenience. But the real insight came when I compared our rush orders vs. standard orders over a full year: we were spending 40% more on artificial emergencies caused by using the wrong vendor.

Why Suppliers Who Say “We Don't Do That” Earn My Trust

Here's something vendors won't tell you: they'll often say yes to work they're not great at, just to keep your business. I've seen it with printers, IT vendors, and even cleaning services. The ones who are honest about their boundaries—like the Otis elevator tech who said “we don't service escalators older than 20 years, you need a specialist”—those become my long-term partners.

To be fair, there are exceptions. If your company has simple, low-risk needs, a generalist might work fine. But for anything involving safety (elevators), precision (screen doors), or food handling (commercial ovens), I'll take a specialist every time.

Consider this: when our office needed face paint for a company Halloween event, I didn't call our usual office supply vendor. I searched online for “where to buy face paint” and found a theater supply company. They gave me better pricing than the generalists could match. Same logic applies to everything else—know your supplier's core expertise, and don't expect them to be great at adjacent fields.

What About the Boston Scally Cap?

You might be wondering where the Boston scally cap fits in. It doesn't—except to illustrate my point. A scally cap is a flat cap popular in Boston. If I needed a batch of branded caps for a corporate event, I wouldn't look for a supplier named “Otis.” I'd go to a promotional products specialist. The name “Otis” doesn't automatically mean “hats” any more than it means “cookies.”

My Updated Vendor Selection Process

After five years of managing these relationships, here's what I now do:

• Check the specialization. If a vendor's website lists 15 unrelated product categories, I ask which one they're best at. The answer tells me everything.
• Ask what they won't do. “Is there any project you'd turn away?” If they say no, I'm suspicious. If they give a specific example, I trust them more.
• Compare apples to apples. For screen door replacement, I got quotes from three specialists and one generalist. The specialist quotes were within 5% of each other; the generalist was 20% lower but unreliable.

Granted, this requires more upfront work. But it saves time later. Our accounting team used to spend 6 hours monthly correcting vendor invoices. After I consolidated with the right specialists, that dropped to one hour.

Final Thought: Embrace Your Supplier's Boundaries

I still work with Otis Elevator for our vertical transportation needs—they're excellent at what they do. But I don't ask them about cookie ovens, screen doors, or historic houses. And I wouldn't expect them to.

The vendor who said “this isn't our strength—here's who does it better” earned my trust for everything else. That's the mindset I now bring to every procurement decision. You should too.

As of January 2025, Otis Elevator's global service network covers more than 2 million elevators and escalators. Their website explicitly lists what they offer: installation, maintenance, modernization. Nothing about cookies. Always verify a vendor's actual scope before assuming.
