A file, not a finding
The output is the thing a disputes desk would have built by hand: a dated timeline with sources, the clause quoted, the arithmetic, the amount at stake, what evidence would make it stronger and who has that evidence — and the letter, ready to send.
Carrier formats
Carriers want disputes in their format: a portal form with specific fields, an email to a specific address with the invoice number in the subject, attachments in a specific order. Templates for the major carriers are maintained; your own can be added. The draft is produced in the right one.
Missing evidence
"Request the empty-return EIR from Trucker X" or "ask the terminal for the yard-hold record for 9–11 Sep" — with the contact if it is in your workspace. Disputes filed with gaps get rejected; the list is there to close them first.
Second rounds
When the carrier replies, forward the reply. The agent reads the stated ground, checks it against the booking and contract, and drafts the response — or recommends closing the dispute if the carrier is right, and records why.
What it does not do
It does not send. A person reviews and presses the button, in the portal or the mail client.
