Is this D&D invoice payable?
Paste the text of one demurrage, detention or per-diem invoice (or upload a text-based PDF). We check it against the 20 elements required by 46 CFR §541.6 and the 30-day issuance rule in §541.7. Under §541.5, an invoice missing a required element eliminates your obligation to pay.
If the check finds a defect, we write your dispute letter for you — free, filled in with the exact rules your invoice failed, yours to send.

One invoice is a screen. The real money is in the pattern: we audit every ocean, D&D, chassis and drayage invoice from the last 12 months against the 20 elements, the 30-day clocks, terminal closures, availability records, your contracts and duplicate billing — and dispute what fails.
