A regional utility company managing 650 field service vehicles across four service zones was facing a compliance crisis in early 2024. Preventive maintenance tasks were falling through the cracks — only 61% of scheduled PMs were being completed on time. Aging work order paperwork, disconnected depot operations, and zero real-time visibility into fleet health had created a system where breakdowns were routine and regulatory inspection failures were a quarterly concern. After deploying Oxmaint as their centralized CMMS, the utility company restructured its entire PM program — and within six months reached 96% PM compliance, reduced unplanned repair costs by 33%, and eliminated overdue inspection backlogs entirely. This is how they did it — and how your utility fleet can replicate the same outcome. Sign Up Free to start building a compliant, proactive fleet maintenance program today.
Build a 96% PM Compliance Program for Your Fleet
Oxmaint gives utility fleets the scheduling, tracking, and visibility tools to move from reactive breakdowns to proactive compliance — starting in week one.
The Challenge
Why 61% PM Compliance Was Threatening Operations and Contracts
61%
PM On-Time Rate
Nearly 4 in 10 scheduled preventive maintenance tasks were missed or deferred — leaving vehicles operating past recommended service intervals.
280+
Overdue PMs Monthly
Paper-based scheduling across four depots created a backlog that field supervisors had no practical way to track or prioritize.
22%
Emergency Repair Rate
More than one in five work orders were unplanned emergency responses — pulling technicians off scheduled work and compounding the backlog.
4 Depots
No Shared Visibility
Each service location managed its own paper logs. Fleet managers had no consolidated view of compliance status across the operation.
$61K
Monthly Emergency Costs
Unplanned repairs, towing, contract overtime, and expedited parts were draining the maintenance budget every month.
3 Audits
Regulatory Risk Events
Three regulatory inspection events in 12 months identified documentation gaps — exposing the utility to compliance penalties and contract risk.
The Solution
How Oxmaint Restructured the Entire PM Program
Oxmaint was selected for its ability to centralize multi-depot fleet maintenance operations, automate PM scheduling across 650 assets, and give fleet managers real-time compliance visibility without replacing existing telematics infrastructure. Implementation followed a phased approach designed to deliver measurable results at each stage before advancing to the next.
Six-Month Implementation Roadmap
From 61% to 96% PM compliance in structured phases
Phase 01
Weeks 1–3: Asset Registry and PM Schedule Build
All 650 vehicles registered in Oxmaint with service history, odometer data, and vehicle age. PM intervals configured from manufacturer specs and regulatory requirements. Automated schedule generated for all assets across all four depots. Compliance baseline established at 61%.
Phase 02
Weeks 4–7: Digital Work Orders and Technician Assignment
Paper-based work orders replaced with digital workflows. Technicians received mobile task assignments with vehicle data pre-loaded. Work order completion rates tracked in real time. PM compliance climbed from 61% to 79% within 30 days of this phase alone. Sign Up Free to see digital work orders in action.
Phase 03
Weeks 8–14: Parts Inventory Control and Reorder Automation
Spare parts digitized across all four depot locations. Minimum stock thresholds set for the top 35 high-frequency utility fleet parts. Automated purchase order generation triggered on stock depletion. Parts wait time dropped from 2.8 days to under 5 hours — removing a key bottleneck that was delaying PM completions. Book a Demo to review parts automation setup.
Phase 04
Weeks 15–24: Compliance Dashboard, Inspections, and Audit Readiness
Fleet-wide compliance dashboard deployed with daily PM status per vehicle. Digital inspection checklists assigned to pre-trip and post-trip workflows. Audit-ready maintenance records generated automatically. PM compliance reached 96% by month six. Zero overdue inspection backlogs recorded in final quarter.

Key Business Impact
Where the 35-Point PM Compliance Gain Came From
+18 pts
Digital Work Orders
Replacing paper with mobile-assigned digital work orders eliminated lost tasks and gave technicians clear daily PM priorities. Biggest single-phase compliance gain.
+9 pts
Parts Availability
Automated reorder cut parts wait from 2.8 days to 5 hours. PMs that previously stalled waiting for stock were completed same-shift.
+5 pts
Automated PM Scheduling
System-generated mileage and calendar-based PM schedules replaced manual tracking. No task could fall through the cracks across four depots.
+3 pts
Compliance Dashboards
Real-time fleet health visibility let managers intervene on at-risk vehicles before PMs became overdue — eliminating the backlog that had built over years.

"
We had been managing 650 vehicles across four sites with clipboards and spreadsheets. Oxmaint gave us one system where every PM, every inspection, every part order is tracked automatically. In six months we went from our compliance director flagging us in audits to our fleet being the benchmark across the division. The Book a Demo conversation we had before signing up showed us exactly what was possible — and the results matched.

Frequently Asked Questions
Fleet PM Compliance and Oxmaint — Common Questions
Is 96% PM compliance realistic for a large utility fleet?
Yes. Industry benchmarks show fleets with digital CMMS systems consistently reach 90–97% PM compliance versus 55–70% for paper-based operations. The key drivers are automated scheduling, mobile technician assignment, and real-time visibility — all provided by Oxmaint. Sign Up Free to configure your PM schedule today.
How quickly will we see PM compliance improvements after deploying Oxmaint?
Most fleets see measurable improvement within the first 30 days — primarily from digital work orders replacing paper and automated scheduling catching overdue tasks. This utility company gained 18 compliance points in the first month of Phase 2 alone.
Does Oxmaint integrate with existing fleet telematics systems?
Yes. Oxmaint connects to existing GPS and OBD-II telematics via standard APIs. Mileage and engine data feeds directly into PM scheduling — no hardware changes required. Book a Demo to confirm compatibility with your current setup.
Can Oxmaint manage PM schedules across multiple depot locations?
Yes. Oxmaint is built for multi-site operations. Each depot manages its own asset register and technician schedule while fleet managers see a consolidated compliance view across all locations — exactly how this utility company operated across four service zones.
Does Oxmaint support regulatory inspection documentation for utility fleets?
Yes. Oxmaint generates digital inspection checklists, captures technician sign-offs, and stores timestamped audit logs per vehicle. Regulatory audit preparation that previously took days is now available on-demand. Sign Up Free to explore inspection compliance workflows.
What is the typical ROI timeline for Oxmaint in a utility fleet context?
This utility company reduced emergency repair costs by $20,000 per month — achieving full platform payback within the first two months. Most fleets demonstrate positive ROI within 60–90 days through maintenance cost reduction and overtime elimination alone. Book a Demo for a custom ROI estimate based on your fleet size.
