Worked example
A 3,500 TEU importer, start to finish.
Annual D&D billed: $480,000. At a 65% defect rate, $312,000 is disputable. At a 75% credit rate, $234,000 comes back.
On Enterprise BCO the cost is $29,400 in platform fees plus a 12% success fee of $28,080, $57,480 in total. Net direct cash recovery: $176,520, a 4.1x return.
Calculator FAQ
How is the estimate calculated?
65% of billed D&D is assumed to carry a Part 541 or incentive-principle defect, and 62% to 97% of defective dollars are credited, with 75% as the expected case. Plan cost uses the tier for your TEU band. The free audit replaces these assumptions with your actual invoices.
Is the 30-day dispute window always exactly 30 days?
At least 30 calendar days from the invoice issuance date. A billing party can give longer, and its invoice must state the timeframe. Treat 30 days as the floor.
What date counts as 'last incurred'?
The last day a charge accrued: typically the full out-gate for demurrage and the empty in-gate for detention or per diem.
