Where freight cost leaks hide in Australian invoices

Most freight invoices contain three to seven line items beyond the headline ocean rate. By the time the AP team receives them, the original quote has long been archived — and discrepancies quietly become normal.

We see five recurring leakage categories on AU-bound containers in 2025: origin local charges drift, ISPS surprises, AMS/ENS surcharges, detention day creep, and rounding on chargeable weight conversions. None are dramatic on their own. Together they routinely add 4–11% to landed cost.

The fix isn't more spreadsheets. It's tying every charge back to the original quote at the shipment level and making variances visible before payment, not three months later in a quarterly review.
