On-time delivery and transit accuracy
Every carrier review starts with on-time delivery rate, and nearly every one measures it too loosely. A flat "percentage delivered on time" hides the real story. The useful version breaks down by carrier, service level, lane, destination region, and time period. In B2B supply chains, the same discipline rolls up into OTIF (on time, in full), which pairs delivery timing with order completeness.
Transit time accuracy adds a second lens: how closely does the actual delivery date match the estimated or promised date? A carrier might hit a 95% on-time target on a generous three-day SLA while consistently missing a tighter next-day window on the same lane. Without lane-level segmentation, that problem stays invisible.
First-attempt delivery success rate captures a cost that on-time metrics miss entirely. A parcel delivered on the second attempt might still count as "on time," but the failed first attempt generated a customer service contact, a redelivery cost, and a dent in customer confidence.
nShift Track's Carrier Performance Report measures each of these delivery performance metrics against carrier-specific SLAs, filterable by carrier, product, and date range.
Exceptions and service quality
Exception rate tracks the events that disrupt delivery: failed attempts, held parcels, misroutes, address issues, returns to sender. Measured in aggregate, it is a health indicator. Measured by carrier and lane, it is a diagnostic tool.
Damage and claims rate matters most when measured by route, carrier, and package type rather than as a global average. A high claims rate on a specific lane suggests a handling problem at a hub or a packaging mismatch for that route, both of which are fixable once identified.
nShift Track's Performance Exception Detail report breaks down exception frequency by type across carriers. The normalized status library means the same exception category maps consistently regardless of how each carrier labels it internally.
Are your carriers charging what they quoted?
Carrier costs rarely match the rate card exactly. Accessorial charges, fuel surcharges, dimensional weight adjustments, and out-of-area fees accumulate. Rate adherence tracking compares what carriers quoted against what they actually charge, shipment by shipment.
Invoice deviation tracking goes further. nShift Track's Invoice Control compares your calculated freight rate against the carrier's billed amount and flags mismatches. The Deviation Report exports verified discrepancies for use in carrier billing reconciliation, turning a manual audit into a systematic process.
Systematic invoice auditing routinely surfaces billing corrections that manual spot-checks miss, particularly on accessorial charges and dimensional weight adjustments that compound across high shipment volumes.
Rate adherence and invoice deviation tracking answer whether a carrier billed what it quoted. A deeper question is coming next: whether the invoice matches what actually shipped. nShift is building toward that next layer of freight and parcel invoice auditing, matching every invoice line against your contract and your real shipment record.

How much can you see between pickup and delivery?
A carrier that delivers on time but provides no scan updates between pickup and delivery creates a different kind of cost: customer service inquiries, internal tracking workarounds, and a branded tracking page with nothing to show.
Status reporting quality measures the percentage of shipments where the carrier provides confirmed pickup, in-transit, and delivered statuses. Some carriers report fifteen events per shipment. Others report two. That gap directly affects how much your customer service team can see and how much your customers can see on their tracking page.
For TMS customers, the Analytics Status sheet is specifically designed to analyse the status quality from the carriers, showing the percentage of shipments with each status type and how that quality varies over time and between carriers.
