The SLA says 98% on-time. The monthly report says you missed it — again — and now there's a chargeback, a frustrated customer and no clear answer as to why. Missed delivery windows aren't random; each one has a cause, and the biggest controllable cause sits in your own yard. OXMAINT AI is the AI-powered maintenance management software that turns every SLA breach into a tracked corrective action and keeps the delivery fleet road-ready — or book a demo of the breach-to-work-order loop in OXMAINT AI.

Delivery SLA Management: Carrier Performance Metrics & Compliance
A missed service window is a penalty, a lost customer, and a cause nobody wrote down. OXMAINT AI is the AI-powered CMMS that logs each SLA breach as an issue, routes it to a ranked corrective work order with a root cause, and attacks the one miss you fully control — vehicle downtime — with PM that keeps trucks road-ready for their windows. Fewer breakdowns against the clock, and a paper trail behind every number on the carrier scorecard.

The SLA Metrics That Actually Get Measured
Carrier performance lives or dies on a handful of numbers, each defined precisely so the scorecard can't be argued with. These are the metrics every delivery SLA is built on — start free and track every SLA breach in OXMAINT AI.
On-Time Delivery (OTD)
Share of orders delivered by the promised date or window.
Target 95–98%
On-Time In-Full (OTIF)
On time and complete — the retailer's combined compliance bar.
Target 98%
Transit Time vs Target
Actual door-to-door time against the committed lane time.
Within lane SLA
First-Attempt Delivery
Delivered on the first visit, no re-attempt or re-route.
Target 95%+
Exception Rate
Shipments that hit a delay, hold or failed-delivery event.
As low as it goes
POD Compliance
Proof of delivery captured and matched to the order.
Target 100%
What Breaks an SLA — and Who Owns the Fix
Not every miss is yours to fix, and that is exactly why a breach needs a cause tagged to an owner. Some causes belong to the carrier, some to the weather — but the two that cost the most are the two you control, and both are maintenance jobs.
CARRIER
Capacity & Cut-Off Miss
Carrier ran out of capacity or missed the pickup cut-off. Logged to the carrier scorecard.
EXTERNAL
Weather & Bad Address
Storms, road closures or a wrong address. Documented, but outside your direct control.
YOURS
Vehicle Breakdown
A truck down mid-route misses every stop after it. The single biggest controllable cause — and a maintenance one.
YOURS
Missed Preventive Maintenance
The breakdown that was due. Skipped PM turns into a roadside failure against the clock.
OPS
Driver No-Show
No driver, no route. A staffing and dispatch gap that needs its own corrective action.
OPS
Route & Dispatch Error
Bad sequencing or a late dispatch. A planning fix, tracked like any other.
The Carrier Scorecard
One ranked view tells you who is holding the SLA and who is costing you penalties. Grade each carrier and lane on OTD and OTIF, see the penalty exposure, and route the fixable causes to action — schedule a walkthrough of the carrier scorecard in OXMAINT AI.

From Missed Window to Closed Corrective Action
A breach on a report changes nothing. A breach with a cause, an owner and a work order changes the next month's number. This is the loop OXMAINT AI runs the moment an SLA is missed.
1Detect Breach
A missed window or failed delivery flags against the SLA.
2Classify Cause
Carrier, external, fleet or ops — tagged to an owner.
3Route
Fleet repair, carrier action or dispatch fix.
4Raise WO
A ranked corrective work order with the cause attached.
5Verify
Fix confirmed; the vehicle or process back in service.
6Close
Root cause and action saved to the record.
Road-Ready Is On-Time: The Fleet-Reliability Side
A carrier scorecard tells you that you missed. It doesn't stop the next miss. For your own fleet, the stop is maintenance — and it is the part OXMAINT AI owns outright. Start free and put your delivery fleet on OXMAINT AI.
Fleet PM Calendar
Service by mileage, engine-hours or date so a due repair is done on the bench, not on the route.
Pre-Trip Readiness
A mobile check before each run — brakes, tyres, lights, fluids — so the vehicle leaves fit for its windows.
Breakdown → Downtime Link
Every roadside failure logged to the vehicle, the route it broke and the SLA it cost.
Downtime Root Cause
Recurring failures trended by vehicle and system so the real cause is fixed, not re-patched.
How OXMAINT AI Supports Delivery SLA Management
OXMAINT AI doesn't replace your TMS or carrier portal — it is the AI-powered maintenance management software that turns SLA misses into corrective action and keeps the fleet that hits those SLAs reliable. Put your first lane and vehicles on it when you start free and build your SLA corrective-action log in OXMAINT AI.
SLA Breach → Work Order
Every missed window becomes a ranked corrective work order with a cause tagged to an owner.
Fleet PM & Readiness
Preventive service and pre-trip checks so vehicle downtime stops costing delivery windows.
Carrier & Vehicle KPI Log
OTD, OTIF and exception rates kept per carrier, lane and vehicle, with the history behind each.
Downtime Root-Cause Analytics
Breakdowns and misses trended so the recurring cause is fixed, not just this month's penalty.
Corrective-Action Trail
Every breach, cause and fix on one record — the evidence a compliance review asks for.
Multi-Site SLA Board
One view across lanes, carriers and depots — on-target, watch or breach — with open work orders.
A Penalty Without a Cause Is a Penalty You'll Pay Again.
The difference between a breach and a fix is the work order — the cause tagged, the owner named, the vehicle serviced. OXMAINT AI closes that gap on one screen, per carrier, per lane, per truck.
EXPERT REVIEW
Written for logistics, delivery-operations and maintenance teams. OXMAINT AI is a maintenance management platform, not a TMS or carrier-tracking system — it works alongside your TMS and carrier portals, turning SLA breaches into corrective work orders and keeping your own fleet road-ready so fewer misses trace to downtime. OTIF bars and penalty terms vary by retailer and contract; the figures here are published benchmarks, not a guarantee of results.
Frequently Asked Questions
Is OXMAINT AI a TMS or carrier-tracking system?
No — it is the maintenance and corrective-action layer. It takes the SLA misses your TMS and carrier portals report, turns each into a ranked work order with a root cause, and keeps your own fleet maintained so fewer misses are downtime.
Start free and log your first breach in OXMAINT AI.
What are the core delivery SLA metrics?
On-time delivery, on-time in-full, transit time versus target, first-attempt delivery, exception rate and proof-of-delivery compliance. OTIF is the bar most retailers hold suppliers to, commonly 98%.
Book a demo of the carrier KPI log in OXMAINT AI.
Why tie delivery SLAs to maintenance at all?
Because the biggest controllable cause of a missed window is a vehicle that breaks down or skipped its service. Preventive maintenance keeps trucks road-ready, so fewer SLA misses are self-inflicted.

What happens when an SLA is breached?
The miss is flagged, the cause is classified and tagged to an owner, it is routed to a fleet repair, carrier action or dispatch fix, a corrective work order is raised, the fix is verified, and the record is closed with the root cause.

Can it show carrier performance across lanes and sites?
Turn Every Missed Window Into a Fix That Sticks.
Put your carriers, lanes and delivery fleet on OXMAINT AI: SLA breaches routed to corrective work orders, fleet PM that keeps vehicles road-ready, and a carrier scorecard across every lane and depot — so next month's number is one you can defend.
