This is a preliminary, indicative check. A full audit additionally verifies invoice formal completeness, force majeure circumstances, and the fine print of your contract.
The calculator compares three things: the total number of days between container discharge and empty return, the free time specified in your contract, and the daily rate that applies after it. The result — what you should owe based on these numbers — is compared to the amount the carrier actually invoiced.
This is a preliminary, indicative check, not a full audit. It does not assess: the invoice's formal completeness (container number, B/L number, a clear period); force majeure circumstances (port congestion, a strike); the nuances of how weekends and holidays apply under your specific contract; or fine print that could change the standard calculation. A full D&D audit checks all of this in addition.
No. It's an indicative, preliminary calculation meant to help you quickly decide whether it's worth digging further. A formal claim to the carrier needs full documentation and contract analysis — that's exactly what a full D&D audit does.
Get in touch. The initial invoice review is free, and we only charge on what's actually recovered — if we recover nothing, you pay nothing.
As accurate as the data you enter. It doesn't account for holiday calendars, force majeure circumstances, or contract fine print — that's what a full audit checks, not a calculator.
Get in touch and we'll tell you within 15 minutes whether it's worth digging into.
