My $4,200 Mistake: Why I Stopped Buying the Cheapest Elevator Parts (And Why You Should Too)

Last year, I almost got us into deep trouble. All because I was trying to save a few hundred bucks.

I'm a procurement manager for a mid-sized office building in Chicago. I've been managing our service contracts and parts orders for about six years. Our annual maintenance budget for building systems—elevators, HVAC, plumbing—hovers around $180,000. It's my job to make every dollar count.

And for most of those six years, I thought I was pretty good at it.

The Problem: A Broken Stair Lift

It started with a phone call from our facilities team. The stair lift in the east wing was out of commission. Not a major emergency—no one was stuck—but it was a problem. We have a few tenants who need it to access the mezzanine level, and they were getting restless.

I got the part number from our lead technician: a drive motor assembly for a ThyssenKrupp stair lift. Standard stuff. I started doing what I always do—calling around for quotes.

Vendor A, our regular supplier for OEM parts, quoted me $2,800. It was a genuine ThyssenKrupp part, with a warranty, and they said they could ship it in three days.

Vendor B, a well-known online marketplace for elevator parts, quoted me $2,100. The part was listed as "compatible" and "high-quality." They said it would ship in two days.

The difference was $700. Almost 25% less. I thought, "This is a no-brainer. Why would I pay for the brand name when I can get a compatible part for less?"

The $700 Savings That Cost Us $4,200

I approved the order for Vendor B. The part arrived on time. Our technician installed it in a few hours. The stair lift was working. Everyone was happy.

For about two weeks.

Then the stair lift started making a grinding noise. Then it stopped moving entirely. The tenant had to be helped out of the lift by our maintenance staff. Not a great look for a building that prides itself on being modern and accessible.

Our technician checked it out. The cheap drive motor had failed. Burned out. He showed me the part: the shaft was warped, the bearings were shot. It was clear it wasn't built to the same specifications, even though it looked similar from the outside.

So now we had to take the failed part out, order a replacement, and pay for the labor to install it again. We went back to Vendor A, bought the genuine ThyssenKrupp part for $2,800, and paid for expedited shipping to get it in two days.

Let's do the math:

• Cost of first part (Vendor B): $2,100
• Cost of installation labor (first time): $800
• Cost of removal & re-installation labor (second time): $1,600
• Cost of genuine part (Vendor A): $2,800
• Total cost of the "cheap" route: $7,200
• Total cost of choosing OEM from the start: $3,600
• Net loss from trying to save money: $3,600

A $700 savings turned into a $3,600 loss—a $4,200 swing against us. That's not just a mistake. That's a budgeting disaster.

People assume the lowest quote means the vendor is more efficient. What they don't see is which costs are being hidden or deferred.

The Real Cost of the 'Lowest Quote'

This wasn't just about one stair lift. This was a pattern I hadn't seen because I wasn't looking at the total cost.

For years, my procurement policy was simple: get three quotes, pick the lowest one that meets basic specifications. That's what I was taught. That's how you save money, right?

Wrong.

I started auditing our spending over the last six years. I went back through every invoice, every service ticket, every warranty claim. What I found was sobering.

About 18% of our "budget overruns" came from situations just like the stair lift—cheaper parts that failed prematurely or didn't fit correctly. We spent $12,000+ on emergency service calls that would have been unnecessary if we'd used the right parts the first time.

The hidden costs were everywhere: technician callbacks, extended downtime that frustrated tenants, and the lost productivity of our facilities team chasing failures instead of doing preventative maintenance.

What I Changed in Our Procurement Policy

After that stair lift disaster, I completely overhauled our parts-buying process. Here's what I implemented:

1. The TCO Rule

Before we approve any parts purchase, we have to calculate the Total Cost of Ownership (TCO). This includes:

• The initial purchase price
• Expected lifespan (based on manufacturer spec or past experience)
• Installation labor costs
• Likelihood of rework or failure (historical data helps here)
• Warranty terms (OEM parts typically have 12-24 months; cheap ones have 90 days, if anything)

2. The 3-Quote Process, Modernized

We still get three quotes. But we don't just pick the lowest price. We rate each quote based on TCO. If a quote from an OEM supplier costs 30% more but has a 50% longer warranty and a proven reliability record, it's usually the winner.

3. The Part Criticality Matrix

We classify each part into three tiers:

• Critical (Level 1): Drive motors, controllers, safety brakes. OEM only. No exceptions.
• Standard (Level 2): Door operators, floor sensors. We will compare OEM vs. quality compatible, but only from vendors with a 3-year track record of positive reviews.
• Consumable (Level 3): Buttons, lights, filters. Cost matters more here, but we still verify specs.

4. Track Every Part Failure

Our technician logs every part failure in a simple spreadsheet. We track part number, vendor, date installed, and date failed. This gives us real data on reliability, not just marketing hype. After 18 months, we can see crystal clear patterns.

The Result: We Cut Overtun Costs by 20%

These changes weren't complicated. They just took discipline. And the results speak for themselves.

In the 12 months since we implemented these new policies, we've cut our budget overrun costs by 20%. That's about $4,000 in real savings—more than making up for the stair lift disaster. More importantly, our elevator and lift downtime is down by 30%. Our tenants are happier. Our facilities team isn't constantly in fire-fighting mode.

Is the OEM part always the right answer? No, not always. There are some decent compatible parts out there. But you have to know which ones, and you have to measure their performance, not just trust their price tag.

But this I know for sure: The cheapest part is almost never the cheapest in the long run. Especially when you're dealing with something as critical as a stair lift or an elevator.

From the outside, it looks like you're just being cheap. The reality is you're signing up for a future of rework, delays, and frustrated customers.

I learned that lesson the hard way, on a Tuesday morning, with a very annoyed tenant stuck in a broken lift. Take my advice: calculate the TCO. It's the real price.
