You got hit with another detention invoice last month. Maybe two. You paid them, grumbled, moved on — because that’s what everyone does in freight. But when you add up every demurrage and detention charge across a full year, the number is ugly. And nobody in your business is tracking whether those charges were avoidable, recoverable, or just the price of poor coordination upstream.
The Cost That Hides in Plain Sight
Demurrage and detention charges sit in a weird no-man’s-land in most logistics businesses. They’re not a line item anyone budgets for. They get coded to freight or general costs. Sometimes they’re buried in a supplier invoice, sometimes they land as a separate bill from the shipping line or terminal weeks after the container moved. Because no one aggregates them, no one sees the pattern. Was it the customer’s slow paperwork? Your yard’s capacity problem? A fumigation delay? A booking that should never have been confirmed on that vessel? Each charge has a cause, and each cause has a fix — or at least a conversation about who should actually be paying. Without that visibility, you absorb every dollar. An outsourced CFO Perth would call this what it is: margin you’re giving away because no one’s watching.
Why Your Current Reporting Misses It Completely
Your bookkeeper codes the invoice. Your accountant sees a freight expense. Neither of them asks whether that $1,400 container detention charge in Fremantle was caused by a customer who took four days to unpack, or a transport booking that fell through. The charge just becomes part of the cost base, and your quoted rates never reflect it. This is a structural gap. Your P&L tells you freight costs went up. It doesn’t tell you that $47,000 of those costs across the year were avoidable penalty charges with identifiable causes. A logistics CFO Perth would break those charges out, tag them by cause and customer, and give you the data to either recover the cost or prevent it. That’s the difference between reporting what happened and reporting what it means.
Recovering What’s Recoverable, Preventing What’s Preventable
Some of these charges belong on your customer’s account. Their late documentation, their slow receival — your detention bill. But you can’t back-charge what you can’t prove, and you can’t prove what you don’t track. Once you isolate demurrage and detention as their own cost centre, three things become possible. First, you can add surcharge or recovery clauses to customer contracts with real data behind them. Second, you can identify repeat operational causes — the same depot, the same customs broker, the same receival window problem — and fix them. Third, you can forecast the cost instead of being surprised by it. None of this requires new software. It requires a financial structure that makes these charges visible to the person making decisions. That person is you.
What a Proper Financial Structure Looks Like Here
At 360 Fox, we’ve seen freight operators absorb five to eight per cent of gross margin in charges they never properly tracked. That’s real money — often enough to fund a new hire or cover a rate increase you’ve been afraid to push through. The fix starts with carving demurrage and detention into a dedicated cost category, tagged by cause, customer, and lane. Then building a monthly view that shows you the trend, the worst offenders, and the dollar value of what’s recoverable. From there, your outsourced CFO Perth builds those charges into quoting models and customer reviews, so the cost either goes away or gets passed on. This is the kind of specific, operational finance work that changes how a logistics business actually runs — not a dashboard, not a forecast no one reads, but a structural change to how you see and manage a cost you’ve been wearing silently for years.
If you’re paying demurrage and detention charges every month and no one can tell you exactly how much, exactly why, or exactly who should be wearing it — that’s not a freight problem. It’s a finance problem. And it’s fixable.
