It started with a spreadsheet. A boring, unremarkable spreadsheet I put together in Q1 of 2019 when my CFO asked a simple question: "Are we getting the best deal on our cable and accessory orders?"
Six years later, that spreadsheet has grown into a monster. 190+ line items across 8 vendors, cumulative spending of roughly $180,000—maybe $175,000, I'd have to double-check the totals. It's the kind of data that tells stories most procurement people never get to see because they're too busy putting out fires.
What it taught me about buying from companies like Nexans SA—and what it revealed about my own blind spots—changed how I think about every vendor relationship I manage.
The Assumption That Cost Us
Here's the thing most buyers get wrong: they focus on per-unit pricing and completely miss the setup fees, revision costs, shipping surcharges, and compatibility headaches that can add 30-50% to the total. That's what I call an outsider blindspot.
When I started tracking, I assumed the vendor with the lowest quote on power cable would give us the lowest total cost. That's not how it works. Not even close.
Take our experience with accessory enclosures in 2022. We needed weatherproof enclosures for a utility project—standard stuff, nothing custom. Vendor A quoted $420 per unit. Vendor B quoted $380. I almost went with B until I calculated the real numbers:
- Vendor B charged $45 per unit for mounting hardware (included with A)
- Vendor B had a $200 flat "small order" fee for orders under 50 units
- Vendor B's shipping added 12% vs A's 6%
Total per-unit cost with B: $492. With A: $445. That's a 10.5% difference hidden in fine print. Vendor A wasn't cheaper—they were just more transparent.
—though I should note this was a comparison of two specific quotes on a specific product line. Not every comparison shakes out this way.
When "One-Stop Shop" Becomes a Red Flag
Around 2021, we started getting pitched by vendors claiming to handle everything—cables, connectors, enclosures, terminations, even installation. The promise was seductive: fewer vendors, simpler logistics, one throat to choke.
But here's where my expertise boundary stance kicks in. The vendor who says "we do it all" is usually telling you they do a lot of things adequately. Not excellently.
"The vendor who said 'this isn't our strength—here's who does it better' earned my trust for everything else."
That actually happened. In 2023, I was evaluating a potential supplier for power accessories—the Platinum BP5450 was on the list—and their sales rep straight-up told me: "We're good at connectors and accessories. For high-voltage cable terminations above 15kV, we'd recommend Nexans or another specialist. That's not our lane."
I respected that so much I put them on our approved list for everything else. Specialists who know their limits are more reliable than generalists who overpromise.
(I should add: this doesn't mean we only work with specialists. We use broader-line suppliers for commodity items. But for anything mission-critical—and power accessories often are—specialization matters.)
The Hidden Cost of "Cheap"
In Q2 2024, we had an incident that cost us $1,200 in rework because I went with a budget option on enclosure gaskets. The "cheap" option was $8 less per unit. The gaskets failed within 6 months. We had to send a crew back to replace them at $380 per trip, plus lost time.
People think expensive vendors deliver better quality because they charge more. Actually, vendors who deliver quality can charge more. The causation runs the other way. That's a case of causation reversal I see all the time in procurement.
Looking back, I should have specified higher-grade materials upfront. At the time, the price difference seemed like free money. It wasn't.
What the Data Actually Shows
After tracking 190+ orders over 6 years in our cost tracking system, I found that roughly 65% of our "budget overruns" came from three causes:
- Incomplete specifications (27%) — asking for "a cable" instead of "a 15kV shielded power cable with XLPE insulation"
- Rush order premiums (22%) — last-minute orders that could have been planned
- Compatibility issues (16%) — accessories that didn't match the cable spec
We implemented a policy requiring detailed specs confirmed in writing before any PO, and we cut overruns by about 40% the following year. Not bad for a policy that costs nothing to enforce.
The Lesson I Keep Relearning
If I could redo my approach to vendor evaluation from day one, I'd change one thing: I'd track total cost from the start, not unit price. But given what I knew then—nothing about how much those hidden fees would add up—my approach was reasonable for the time.
The vendors I trust most now are the ones who help me avoid those hidden costs. Nexans power accessories, for example—I've ordered the Platinum BP5450 several times. The per-unit price isn't the lowest. But the total cost is, because the spec is clear, the compatibility is documented, and I've never had a reorder due to quality failure.
"The lowest quoted price often isn't the lowest total cost. The vendor who helps you see the full picture—that's the one worth keeping."
That spreadsheet I started in 2019? It's still growing. And it still surprises me.
— A procurement manager who learned the hard way that unit price is just the cover price. The real story is in the fine print.
