When a cement plant's kiln main drive gearbox fails and an external contractor takes seven days to complete a repair that should take four, the extra three days of downtime costs more than the contractor's entire annual billing. Yet in most plants, the only record of that event is an invoice — no response time logged, no quality rating captured, no repeat failure count tracked. The next shutdown cycle, the same contractor is called again because no one can prove the last job went wrong. OxMaint Contractor Performance Records change this by attaching every vendor interaction to the work order that generated it — response time, repair duration, invoice vs quote variance, post-repair failure rate, and quality sign-off — creating a factual performance history that surveyors, finance teams, and procurement managers can all read from the same screen.

VENDOR MANAGEMENT — CEMENT MAINTENANCE
Your Best Contractor and Your Worst One Look Identical — Until OxMaint
OxMaint tracks vendor response time, repair quality, invoice accuracy, and repeat failure rates across every cement plant work order — giving procurement the data to reward good contractors, replace poor ones, and negotiate from a position of fact.
What Gets Measured — and Why Each Metric Matters
01
Response Time
Time from work order issue to contractor on-site, measured against the SLA commitment. Every hour of late response on a kiln stoppage is a production hour lost — tracked per call-out, averaged per vendor.
What it catches: slow emergency mobilisation
02
Repair Duration vs Estimate
Actual labour hours on the job compared to the quoted scope. Contractors who consistently run 30–50% over estimate are either scoping poorly or padding hours — both cost the plant money beyond the invoice.
What it catches: scope inflation and inefficiency
03
Invoice vs Quote Variance
Final invoice compared to accepted quote for every job, tracked cumulatively. A contractor averaging 18% invoice uplift across 12 jobs is a systematic overspend pattern — visible only when every job is recorded against the same vendor ID.
What it catches: consistent overbilling patterns
04
Repeat Failure Rate
If an asset repaired by a contractor fails again within 90 days, OxMaint flags the new work order as a repeat failure and links it to the prior repair. A contractor whose work fails at three times the plant average is a liability, not a resource.
What it catches: poor repair quality
05
Compliance and Sign-Off Rate
Permit compliance, safety observations, and quality sign-off completion rates per contractor. Vendors who cut corners on PTW documentation or skip post-work sign-off create audit exposure — the record shows it before an auditor does.
What it catches: compliance shortcuts
06
Cost per Repair — Trend
Average contractor cost per repair type over time, compared across vendors doing similar work. If Contractor A averages $8,400 per kiln bearing job and Contractor B averages $5,200 for equivalent scope, the data makes the case for a vendor switch.
What it catches: cost competitiveness
VENDOR SCORECARD — BUILT FROM EVERY WORK ORDER
Stop Renewing Contracts Based on Relationships. Start Using Performance Data.
OxMaint builds a vendor performance record automatically from every work order your contractors touch — response time, quality, cost, and repeat failures. Your next contract negotiation starts with a scorecard, not a handshake.

Scores calculated automatically from OxMaint work order data — no manual vendor assessment required.
From Performance Data to Procurement Action
Score A — Preferred Vendor
Vendor is added to the preferred supplier list for that work category. Future work orders auto-suggest this contractor. Their rates and SLAs are used as the benchmark for competitive tenders.
Score B/C — Performance Review
Procurement initiates a quarterly performance review meeting with the vendor. Specific metrics — invoice variance or repeat failures — are presented from OxMaint data. Improvement targets are set and tracked in the next quarter's scorecard.
Score D — Contract Challenge
OxMaint generates a performance summary report for the vendor file. Procurement uses the documented history to require competitive re-tender, impose penalty clauses, or terminate the contractor relationship — with a factual basis that protects against disputes.
Frequently Asked Questions
How are vendor scores calculated — can we customise the weighting?
OxMaint calculates vendor scores from configurable metric weights. A cement plant that prioritises repeat failure rate above invoice variance can increase the weighting on quality metrics; a cost-focused plant can weight invoice accuracy more heavily. Scores update automatically as work orders close against each vendor.
Book a demo to configure vendor scoring for your plant's priorities.
Can we track sub-contractors, not just the lead contractor company?
Yes. OxMaint supports vendor hierarchies — a lead contractor company with individual technician or crew records beneath it. This allows plants to identify that a contractor firm scores well overall but one specific crew has a consistently high repeat-failure rate, enabling targeted action rather than blanket contractor replacement.

Does OxMaint track contractor safety performance, not just repair quality?
Yes. Safety observations, near-miss reports, permit violations, and toolbox talk compliance linked to a contractor's work orders flow into the performance record. Plants required to demonstrate contractor safety management for ISO 45001 or internal HSE audits use OxMaint contractor safety data as the primary evidence source.
How long does it take to build a useful vendor performance history in OxMaint?
Actionable performance trends typically emerge after six to twelve weeks of consistent work order closure with contractor data attached. Plants that import historical work order data from prior CMMS systems can build a meaningful vendor baseline from day one of OxMaint deployment rather than waiting for new data to accumulate.
Can vendor performance reports be shared with the contractor directly?
Yes. OxMaint generates a vendor-facing performance report — showing their own scorecard data for the defined review period — that can be exported as a PDF and shared in a performance review meeting. Contractors who see their own response time and repeat failure data respond to improvement targets more constructively than verbal feedback alone.
