A 17% reduction in annual maintenance costs is achievable without switching vendors—simply by auditing your spare parts ordering pattern. That's the single biggest finding from my deep dive into our KONE elevator service contracts and historical spending data.
Over the past 6 years, I've managed our building's KONE equipment maintenance budget—roughly $180,000 in cumulative spending. I've negotiated with 15+ vendors for parts, service contracts, and emergency repairs. And one thing became crystal clear: the cost spike we all feel isn't in the monthly fee. It's in the parts.
Where the Real Cost Creep Happens
You might think the bulk of your budget goes to the base service contract—the one that covers labor, inspections, and basic oil changes. You'd be wrong. At least, that's what my spreadsheet said when I started tracking every single invoice in our procurement system back in 2023.
I compared costs across 8 different maintenance quotes over 3 months using my total-cost-of-ownership (TCO) spreadsheet. Every time, the base fees were within a few hundred dollars of each other. But the parts markup? Wildly different. Vendor A quoted a door hinge (KONE door hinge part) at $48. Vendor B quoted $38. I almost went with B until I cross-referenced it with our reliability data.
Turns out, the 'cheaper' part from Vendor B failed 18 months earlier on average than the OEM part from Vendor A. That's a hidden cost. Replacing a hinge means labor, downtime, and tenant complaints. The $10 saving costs me $200 later. Every cost analysis pointed to the budget option. Something felt off. Turns out that 'saving money' upfront was just a preview of 'spending later.'
The Strategy That Cut Our Costs by 17%
Looking back, I should have done this two years earlier. If I could redo that first year, I'd invest in better data tracking upfront. But given what I knew then—nothing about how dramatically parts costs varied—my choice was reasonable.
Here's what I did. I collected every invoice for KONE elevator services and parts for the past 3 years. Then, I created a simple spreadsheet divided by part type. I noticed that our 'spare parts' category had the highest variance. A sliding door for an elevator (KONE sliding door part) could cost between $250 and $400 depending on the vendor and the urgency of the order.
The key move was shifting from reactive ordering to planned ordering. Instead of calling a vendor when a part broke and paying emergency rates, I built a 6-month forecast based on our historical failure data. Then, I negotiated bulk pricing with the vendor for those pre-identified parts.
After tracking 45 orders over 2 years, I found that 68% of our 'budget overruns' came from emergency part sourcing. We implemented a policy requiring a 4-week lead time for non-critical parts and cut those overruns by 31%.
The result? Our annual spend on KONE escalator parts dropped by 17%. Not by switching vendors. Not by cutting corners. But by aligning our purchasing process with the actual lifecycle of the parts.
The 'New Normal' in Elevator Maintenance
What was best practice in 2020—just pay the monthly fee and call for parts as needed—may not apply in 2025. Labor costs are up. Part lead times are longer. And the margins on those 'cheap' third-party parts are shrinking as OEM parts become more differentiated.
Industry data from FTC guidelines on advertising remind us that claims like 'OEM equivalent' must be substantiated. But in practice, 'equivalent' isn't always 'equal.' The technology in a KONE Ecodisc® system isn't just a motor—it's a proprietary energy‑efficient design. A generic part might fit, but will it perform?
The fundamentals haven't changed—safety and reliability are still paramount—but the execution has transformed. A procurement manager who doesn't audit their parts spending is leaving money on the table. And a building that doesn't plan for parts replacement is risking a 'downtime emergency' that costs $400 in rush fees for a single door hinge.
Knowing When the Strategy Doesn't Apply
This approach works for routine, predictable maintenance. If you're dealing with a major modernisation—a full elevator cab replacement or a machine room‑less (MRL) installation—the cost structure is entirely different. Those projects require a separate bid process and don't follow the same parts ordering logic.
Also, if your building has only one elevator, the savings might be smaller. The 17% reduction was calculated on multiple units, which allowed for statistical smoothing of failure intervals. For a single unit, a single 'emergency' can eat up the savings of a whole year.
Finally, this isn't a license to squeeze your current vendor to the bone. The relationship still matters. I still use the same vendor we started with, but now we talk in terms of 'forecasted volumes' and 'lead time commitments' rather than just price. It's a partnership, not a one‑time negotiation.
So, if your elevator maintenance budget is climbing and you're wondering where the money went, don't just look at the service contract. Open the invoice log. Look at the parts. That's where the real cost creep lives.
