Dwellback’s demurrage invoice audit
Dwellback audits U.S. ocean-import demurrage and detention invoices, offers a calculator, and prepares disputes over charges it says may be challengeable.
- For
- U.S. ocean-freight importers
- Worth noticing
- Its worked invoice flags a 34-day billing delay, terminal-closure days, and missing invoice disclosures.
Field notes
The page walks through demurrage (a full container at the terminal) and detention (carrier equipment held after pickup), then applies four cited rules to an invoice. Its sample is explicitly labeled made-up: it flags a bill sent 34 days after the final charge, terminal-closure days, and missing dispute or compliance details. Dwellback says importers file any FMC complaint in their own name; the page does not independently establish how the rules apply to a specific case.
