So here's the thing. I manage ordering for a mid-sized regional airport—think a few hundred staff across three terminals, plus the maintenance hangars and parking structures. It's not a massive operation like Dallas/Fort Worth, but it's big enough that I spend about $1.2M annually on everything from cleaning supplies to HVAC filters. And for the past few months, I've been wrestling with one question: is it better to find a vendor who can do everything, or work with specialists who only do one thing really well?
You'd think the answer is obvious—consolidation saves time, right? Fewer invoices, fewer relationships to manage, simpler accounting. That was my thinking when I took over purchasing back in 2020. By 2022, I'd consolidated from 15 vendors down to 6, and by 2024, I was down to 4. Each time, I was chasing that same promise: "We handle everything you need."
And each time, I learned that promise comes with a hidden cost.
This whole topic came up because we're finally replacing our parking structure lighting—old metal halide fixtures that are costing a fortune in maintenance. I've been looking at suppliers, and the name that keeps coming up is sports lighting manufacturer like Musco. But I'll get to that. First, let me explain why I've become a skeptic of the "one-stop shop."
The Surface Problem: Too Many Vendors, Too Much Admin Work
Look, every procurement person has this pain. Processing 60-80 orders annually across multiple vendors is tedious. Each vendor has their own invoice format, their own PO process, their own delivery window. You spend half your time just reconciling paperwork.
In our 2024 vendor consolidation project, I calculated we were spending roughly 8 hours a month just on order processing for our lighting-related vendors alone. That's a full day out of my month that could be spent on—I don't know—actually improving something.
So when a company says "we can handle your lighting, your electrical, maybe even your HVAC controls," it sounds appealing. One contract, one invoice, one relationship. Who wouldn't want that?
But here's where it gets tricky.
The Deeper Reason: When "Everything" Means "Nothing Special"
I've had this conversation with at least three different facilities managers at industry meetups over the past year. The pattern is always the same: a vendor pitches themselves as a full-service provider, and initially it works great for the basic stuff. But when you need something specific—like, say, lighting for a 60-foot-high hangar ceiling with specific uniformity requirements—they start to struggle.
Part of me wants to believe in the one-stop shop. On one hand, it simplifies my life considerably. On the other hand, I've seen the quality drop-off when vendors step outside their core competency. A commercial electrical contractor might be great at wiring offices but completely miss the mark on sports lighting specifications. They don't understand glare control for players or the specific mounting heights needed for even coverage.
I have mixed feelings about generalists. On one hand, they're convenient. On the other, I've had to redo work because a "full-service" vendor didn't have the specialized knowledge they claimed. How I reconcile this? I've started asking vendors point-blank: "What is your core focus? What do you do better than anyone else?"
A vendor who said "this isn't our strength—here's who does it better" earned my trust for everything else.
The Cost of Getting It Wrong
The most frustrating part of vendor management: the same issues recurring despite clear communication. You'd think written specs would prevent misunderstandings, but interpretation varies wildly, especially when a vendor is trying to fit your project into their available product range rather than recommending the right solution.
I remember a situation back in 2022. We needed lighting for a hangar expansion—high ceilings, needs to be bright enough for maintenance work but not create shadows that hide cracks on aircraft surfaces. Pretty specific requirements. We went with a vendor who claimed they could do it all. They installed standard high-bay fixtures. The lighting was uneven, created glare issues, and the maintenance crew complained within a week.
The upside of going with a specialist was clear in hindsight: better specs, fewer headaches. The risk of going with a generalist was wasted time and rework. I kept asking myself: is the convenience of a single vendor worth potentially getting subpar results for specialized needs?
Calculated the worst case: complete redo at $12,000. Best case: it works well enough. The expected value said go with a specialist for specialized needs, but the downside of managing another vendor felt annoying. In the end, the redo cost us time and budget—and it made me look bad to my VP when the project ran over.
That unreliable supplier made me realize: convenience that compromises quality isn't really convenience at all.
The Specialist Approach: Knowing Your Limits
This brings me back to the lighting decision we're facing now. Replacing parking structure lights isn't the same as lighting a hangar, but it's still a specialized application. You need fixtures that can handle outdoor conditions, provide even illumination across large areas, and work with controls for energy management. And the mounting height and light distribution are different from, say, a warehouse or an office.
When I look at a sports lighting manufacturer like Musco, I know what I'm getting. They're not trying to sell me office lighting or residential fixtures. Their focus is large-scale outdoor venues—sports fields, airports, large facilities. Their Green Generation technology is specifically designed for high-mast applications where efficiency and uniformity matter.
And here's the thing: they'll tell you when a standard solution won't work for your specific site conditions. They'll talk about the variables—mounting height, reflective surfaces, ambient light, control system integration. That's the mark of someone who actually knows their space. They're not promising a generic product that "works for everything."
I'd rather work with a specialist who knows their limits than a generalist who overpromises. The vendor who said "this isn't our strength—here's who does it better" earned my trust for everything else they do well.
Now, I'm not saying generalists are useless. For basic, standardized needs—desk lamps, standard office lighting, basic electrical work—a full-service vendor can be perfectly fine. The convenience of one contract and one invoice has real value.
But when the requirements get specific? When you're dealing with 80-foot mounting heights, specific light uniformity ratios, or control integration across multiple zones? That's when you want someone who breathes that stuff every day.
Per FTC guidelines (ftc.gov), claims like "full service" or "complete solution" need to be substantiated. If a vendor says they can handle everything, ask for examples that prove it. Specifically ask about projects similar to yours, not just vaguely related work.
So Here's What I Do Now
After the hangar lighting disaster, I changed my approach. I still use generalists for standard stuff—basic maintenance, consumables, things where specifications are well-established. But for anything specialized—lighting for high bays, outdoor areas, anything with specific performance requirements—I go to specialists.
My process is pretty simple:
- For standard needs: one or two full-service vendors. Simple, efficient, cost-effective.
- For specialized needs: 2-3 targeted RFQs with specialists who clearly focus on that area.
- I ask every vendor: "What's your core expertise? What project makes you most proud?"
- I check if they're transparent about what they don't do well.
For example, when I was getting quotes for our parking structure lighting replacement, I specifically looked for vendors with experience in airport parking facilities and high-mast outdoor lighting. That led me to companies like sports lighting manufacturers who have done similar projects for stadiums and large venues. Their experience with specific mounting heights and light distribution patterns is directly applicable.
Bottom line: a specialist who admits their boundaries is more trustworthy than a generalist who promises the moon. I've learned that the hard way—through budget overruns, delayed timelines, and at least one awkward conversation with my VP about why a "simple" lighting project needed a redo.
The most reliable vendors I work with now are the ones who said early on: "We're great at X. For Y, we recommend talking to someone else." That honesty built more trust than any claim of being a one-stop shop ever could.
