Demurrage & detention costs exploded 3-5x post-COVID. Legacy audit companies use manual labor and check 10-20% of invoices. AuditDray audits 100% of invoices in under 60 seconds — and auto-generates disputes with evidence.
Cass, CTSI-Global, Trax — they're 15-30 year old companies using hundreds of manual reviewers. They can't audit D&D well because they lack container tracking data.
Legacy auditors check a sample. 80%+ of your invoices go completely unchecked. Errors slip through every month.
Manual data entry, spreadsheet reconciliation, back-and-forth. By the time they find errors, dispute windows are closing.
With hundreds of human reviewers on payroll, legacy companies charge $5-15 per invoice — and still miss most errors.
One invoice. Six AI steps. Every charge line verified against your contract. Errors flagged with evidence. Dispute letter ready to send.
This demo runs automatically. 5 charge lines, 3 errors found, $1,425 in savings.
Other tools stop at a list of errors. AuditDray closes the loop — every overcharge automatically becomes a dispute with a professional letter, contract references, correct calculations, and a container event timeline.
Every charge line verified: free time calculation, rate tier, container size, hold periods, return dates. 9 error types detected.
Contract clause references, correct calculation breakdown, container event timeline, and confidence score — all packaged automatically.
Professional dispute letter with specific charges disputed, requested credit amount, and all supporting evidence. Download PDF or send directly.
Every one costs real money. Legacy auditors miss most because they lack container tracking data and can't reason over complex contract terms.
Carrier counted fewer free days than your contract allows. Off by one day at $300/day adds up fast.
Billed at the day 6-10 rate when container was still in the day 1-5 tier. Rate tiers exist for a reason.
Charged 40' rate on a 20' container. We auto-detect container size from ISO 6346 number format.
Container had customs/freight hold but the clock kept running. Your contract excludes hold days — we verify.
Container returned Monday, invoice bills through Wednesday. We cross-reference return dates against charge periods.
Terminal closed Sat/Sun but invoice counted both. Contract excludes non-operating days — we check every one.
Same container, same dates, billed on two invoices. Invisible across hundreds of invoices per month.
Days × rate ≠ line total. Rounding, wrong multiplication, or plain arithmetic mistakes on the invoice.
Contract says availability, carrier started at discharge — often 1-2 days earlier. We know the difference.
This product couldn't exist two years ago. Now it can.
GPT-4o vision reads PDFs as images — any format, any layout, any carrier. No OCR templates. No data entry. Near-human accuracy on tables, rates, and dates.
Post-COVID, demurrage & detention charges skyrocketed and haven't come back down. A mid-size shipper now pays $300K+/year in D&D alone. The pain is acute.
Terminal APIs, tracking services, and EDI feeds now provide container movement data (discharge, availability, holds, return) that legacy auditors never had access to.
Cass, CTSI-Global, and Trax use hundreds of manual reviewers. We built it with AI from day one.
Drag the slider to see estimated annual savings based on a 15% average D&D error rate.
AuditDray is built by the tech co-founder of PortPro, a drayage TMS used by carriers across the US. Years of building tariff matching engines, container tracking systems (TrackOS), D&D calculation logic, and billing exception workflows.
This domain expertise — understanding how free time rules interact with terminal operations, how holds pause billing, how tiered per diem rates apply across container sizes, how ISO 6346 container numbers encode size data — is what makes our AI accurate where others fail.
No monthly fees. No per-invoice charges. Pure savings-share. If we don't find overcharges, you pay nothing.
Send us 3 months of D&D invoices + contracts. We audit every invoice and deliver a detailed savings report. Free.
If we find savings, we charge a percentage of recovered amounts. You keep the majority. We grow when you save.
