Upload the rate confirmation, capture arrival and departure proof, attach the POD, and generate a tamper-evident detention packet with a public verification link.
When detention gets denied, the question is not whether you typed an invoice. The question is whether you can prove what happened, when it happened, where it happened, and whether the paperwork changed later.
Your phone says you arrived at 8:47. The broker says 10:15. Without a sealed location-and-time event, it becomes a story contest.
A normal detention invoice can be changed, re-exported, renamed, or disputed. A sealed hash turns alteration into a visible failure.
Rate confirmation, arrival, departure, POD, and photos usually live in separate places. DetentionProof binds them into one packet.
If denying detention costs less than paying it, brokers deny it. Sealed evidence changes the cost of the argument.
The MVP stays narrow on purpose. One pain point. One money event. One packet a broker, factoring company, attorney, or collections firm can verify.
The agreed detention terms become the first link in the evidence chain.
Use the phone browser to capture arrival time, GPS coordinates, and location accuracy.
Capture departure the same way and calculate billable detention from the rate confirmation.
Upload the proof of delivery, dock photos, email screenshots, or any supporting documents.
Download the tamper-evident PDF and share the public verification URL with anyone.
Nobody should need an account to check a packet. The verifier shows whether the seal is intact, whether the documents match their hashes, and whether the arrival/departure events are present.
The user pays to create sealed packets. Brokers, factoring companies, attorneys, and collections firms verify for free.
