The Detention Fee You're Forgetting to Bill (And How to Fix It)

Detention fees are legitimate revenue you have already earned. Most fleets under-bill them for structural reasons, not careless ones. Here is a practical system to capture them.

A detention fee is a charge applied when your vehicle is held at a loading or offloading point beyond the free time agreed in the contract. It compensates you for an asset that is earning nothing while somebody else's process runs late. It is ordinary, contractual revenue — and it is one of the most consistently under-billed lines in trucking.

Why detention fees slip through

The reason is structural rather than careless. Detention is observed by the driver, at the gate, hours from the office. That observation has to survive a journey through dispatch and into invoicing, and at each handover it loses precision. By invoice time the timing is approximate, nobody is certain the delay qualified, and the safest thing to do is drop it.

  • No standard way to log delay start and end times at the moment they happen
  • Ambiguity about what qualifies as billable under the specific contract
  • Disconnected records between driver, dispatcher and finance
  • No link between the delay and the trip it belongs to, so it is invisible at invoicing

What detention is worth

The amount is easy to underestimate because each individual instance looks small. It is the frequency that matters.

Worked illustration: A fleet running 120 trips a month, where one trip in five incurs four billable hours at KES 1,500 per hour, is owed 24 × 4 × 1,500 = KES 144,000 a month, or about KES 1.7 million a year. Substitute your own trip count and rate — the point is that the annual figure is rarely small.

That revenue requires no new clients, no new vehicles and no rate negotiation. It is work already performed under terms already agreed.

How to set up a detention tracking system

  1. Write down what qualifies. Free time, hourly rate and any cap should come straight from the contract, per client, so nobody has to make a judgement call at the gate.
  2. Give the driver one place to record arrival and release times at the moment they happen, not from memory at the end of the day.
  3. Attach the detention record to the trip, so it travels with the vehicle, driver, client and route rather than sitting in a separate log.
  4. Review detention weekly against trips, so a missing entry is caught while the driver still remembers the day.
  5. Reconcile at invoicing by pulling from the trip record rather than from anyone's recollection.

In Travada, detention is a first-class income type alongside rate income. Both are recorded against the same trip, so the per-trip profit figure already includes detention and the invoice can be reconciled against the trip record rather than reconstructed.

The negotiating benefit nobody expects

Consistent records change the conversation with a client. An operator who can show that a particular consignee held vehicles for an average of five hours across forty trips is not making an accusation — they are presenting a pattern. That is a far stronger position for renegotiating free time or rates than a general complaint about delays, and it frequently reduces the delays themselves.

Detention fees: common questions

What is a detention fee in trucking?

A detention fee is a charge for time a vehicle spends waiting at a loading or offloading point beyond the free time agreed in the contract. It compensates the carrier for an asset that is idle and unable to earn, and is normally billed per hour after a stated threshold.

How much detention can I charge?

The amount is set by your contract with the client, not by a regulated rate, so it varies by agreement and by market. What matters more than the rate is that the free-time threshold and the hourly charge are written down per client before the delay happens, since fees agreed after the fact are the ones that get disputed.

When does detention time start?

Typically at the end of the contracted free period, which itself starts when the vehicle arrives and reports for loading or offloading. Because the start point is contractual rather than universal, the arrival time needs recording at the moment it happens — reconstructed timings are the most common reason a detention claim fails.

Why do fleets fail to bill detention?

Almost always because the information degrades in transit. The driver observes the delay, dispatch hears about it later, and finance invoices later still. Without a record attached to the trip at the time, the claim becomes a matter of memory, and uncertain claims get dropped rather than argued.

Should detention be tracked separately from rate income?

It should be recorded as its own income type but attached to the same trip. Keeping it separate lets you see how much of your revenue depends on delays, which is useful for client negotiations; attaching it to the trip ensures it reaches the profit figure for that journey rather than sitting in a log nobody reconciles.
