Measuring service quality

How do you measure a freight forwarder's service quality?

A freight forwarder's service quality comes down to six measurable indicators: on-time delivery against the quoted transit time, incident rate by type, response time to messages, the gap between quoted and invoiced price, per-shipment satisfaction, and NPS. What makes a figure useful is not its level but its definition: always ask for the denominator, the scope, the period, and what is excluded from the calculation. A forwarder who cannot answer is not measuring.

Most freight tenders compare prices and promises. Almost none measure service quality, because there is no shared set of metrics: every forwarder presents the figures that suit it, with its own definition. Here are the six metrics that make a real comparison possible, and the questions that tell you whether a claimed figure means anything.

The six metrics that matter

1. On-time against the quoted transit time. The share of shipments delivered within the transit time sold in the accepted quotation. This is the central metric: “reliable” means “hits its dates”. It is computed shipment by shipment, comparing what was sold to what happened — never by comparing two averages.

2. Incident rate, broken down by type. The share of shipments that hit at least one disruptive event, with the breakdown: rollover or cargo split, booking to redo, pre- or on-carriage to rearrange, customs inspection, document to correct, cargo lost or damaged, invoicing dispute. The breakdown tells you more than the headline rate — it shows where the provider is weak.

3. Responsiveness. The share of client messages that got a first human reply within a stated threshold, during business hours. Pin down the threshold and the time zone: “within 30 minutes during the handling office’s business hours” is not the same claim as “within 4 hours”.

4. The gap between quoted and invoiced price. The share of shipments invoiced within a tight band around the quote. Some gaps are unavoidable and legitimate: demurrage and detention, storage, truck waiting time, customs inspection. They must be excluded from the calculation and stated as such. The rest — rate error, forgotten line, stale rate card — is a measurable failure.

5. Per-shipment satisfaction. The share of shipments rated positively by the client at delivery. Simple, but only if the response rate is published alongside: 98% satisfaction on 3% of shipments rated means nothing.

6. Net Promoter Score. Promoters minus detractors. Useful for the trend, fragile when few people answer: always ask for the response rate.

Checking a claimed figure: four questions

A percentage on its own is never verifiable. Four questions are enough to tell a measured figure from a manufactured one.

  • What is the denominator? 96% of what: of all shipments, or only of those the client bothered to rate? And what share of the activity does the measurement actually cover? A provider can give you that coverage rate without disclosing its volumes, which are commercial data.
  • What is the scope? Which entity, which corridors, which modes. A group figure presented as a local one is a false figure.
  • What is the period? A year-to-date number smooths what a quarter reveals. Ask for both.
  • What is excluded? This is the most revealing question. An honest methodology writes its exclusions before publishing its result: cancelled files, client-caused delays, shipments in transit, cost lines that cannot be anticipated.

A provider who answers those four without preparation genuinely measures. A provider who offers to come back to you does not.

Writing them into a contract

Three rules make a service quality commitment usable:

  • Write the definition, not just the target. “95% on time” commits to nothing without the formula, the denominator and the exclusions.
  • Set a quarterly review. A month is too noisy; a year is too late to correct anything.
  • Provide for access to anonymised raw data. A metric you cannot recompute is a statement, not a measurement.

Why almost nobody publishes these figures

Because publishing them means agreeing to show the bad quarters too. Most forwarders prefer hand-picked references and satisfaction rates with no denominator. That is exactly what makes the exercise discriminating: a provider willing to define its metrics, measure them across its whole scope and publish them at a regular interval is taking a risk the others decline.

At OVRSEA these metrics are tracked internally at group level, with their definitions, known biases and exclusions documented. A quarterly publication is in preparation, on the principle described here: the figure, its formula, its scope, its coverage and its extraction date. Volumes are not published: they are commercial data, and the coverage rate is enough to make a percentage interpretable.

FAQ

Which service quality metrics should I ask a freight forwarder for?

Six are enough: the percentage of shipments delivered within the transit time quoted, the share of shipments that hit an incident and its breakdown by type, the percentage of client messages answered within a stated threshold, the gap between quoted and invoiced price, the share of shipments rated positively by clients, and the Net Promoter Score. Ask for the last twelve months, with the coverage rate of each measurement: what share of the activity the percentage actually covers.

How do I check whether a claimed on-time rate is honest?

Ask three questions. On-time against what: the transit time sold in the accepted quotation, or an estimate revised along the way? What tolerance applies: delivered to the day, or plus or minus two days? What is excluded: cancelled files, client-caused delays, shipments still in transit? An on-time rate without those three answers cannot be compared between forwarders.

What counts as a good on-time rate in international freight?

There is no reliable public benchmark, because almost no forwarder publishes its figures and definitions vary. The order of magnitude depends mostly on mode and corridor: a direct air shipment and an ocean shipment with transhipment are not equally exposed. What is comparable is the trend of one metric over time at one provider, and how that provider handles the shipments that run late.

Why is my freight invoice different from the quotation?

Some cost lines cannot be anticipated at quotation time: demurrage and detention, storage, truck waiting time, customs inspection. Those are legitimate. Other gaps come from a rate error, a line forgotten in the quote, or an out-of-date rate card: those are avoidable, and a serious forwarder tracks them as incidents. Ask for the share of your shipments invoiced within 5% of the quote.

How do I write service quality into a freight contract?

Define every metric in writing with its formula, denominator and exclusions, set a quarterly review, and require the provider to supply anonymised raw data on request. A numeric commitment whose definition is not written down is worthless: at the first disagreement, each side defends its own way of calculating.
