No More Excel Formulas.
No More Surprise Costs.

Many freight forwarders and importers manage containers on spreadsheets, checking carrier websites manually and relying on formulas to track free time. CocoonDEM replaces this with automated demurrage and detention calculations.

The system stores customer-specific and default rates, tracks free time, calculates actual costs and helps teams act before charges damage margins.
