Your cargo moved.
Your fees deserve scrutiny.
Demurrage and detention charges aren’t always justified. PortProof audits your invoices online and disputes incorrect fees—so you only pay us when money is recovered.
For importers. Entirely online. Recovery-based fees.
The PortProof principle
A charge on an invoice isn’t proof you owe it.
What you can expect
No recovery, no fee.Our payment depends on money recovered, not invoices reviewed.
Evidence before escalation.We build disputes around the invoice, the timeline, and the cause of delay.
An honest assessment.Not every fee is recoverable. We won’t promise that yours is.
From invoice to evidence
Keep goods moving.
We’ll question the charges.
A terminal closure, unavailable chassis, or congested port can leave you paying for a delay you didn’t cause. We look beyond the total to understand what actually happened.
What we review
- Demurrage: time billed while a container remains at the terminal.
- Detention: time billed before equipment is returned.
- Incorrect billing, late invoices, and delays outside your control.
- 01
Share the invoice and timeline
Start online with your demurrage or detention invoice. We’ll identify the supporting records needed, such as availability dates, return records, and delay notices.
- 02
Put each charge under review
We audit the billed dates, invoice timing, and circumstances of the delay to identify fees with a basis for dispute.
- 03
Make the case for recovery
We prepare and pursue evidence-backed carrier disputes. You keep running your import operation; we handle the recovery work.
- 04
Pay only when funds are recovered
Our fee is tied to the recovery. If no money is recovered, you don’t pay PortProof a recovery fee.
Aligned incentives
Recovery first. Our fee second.
You only pay when money is recovered. Contact us to discuss your invoices and agree the recovery fee before work begins.
Don’t let questionable fees go unquestioned
Start with one invoice.
Tell us what you were billed and what caused the delay. Let’s find out whether there’s a case for recovery.
