Every document a shipment needs, in one file
Open a shipment and Sila lists every document it requires, who provides each one and by when. Every party submits into the same file.

What's in a shipment file
The checklist
Built from the goods' tariff lines, origin and terms; each item has an owner and a due date.
Duty and approvals, early
The duty estimate and the agencies that release the goods, before they ship.
Requests and reminders
Each party gets a link to what it owes, and a reminder when it is due.
The importer decides who gets what
Documents reach the importer first, who sends each on to the parties that use it, by hand or automatically as it comes in.
Company papers from the account
Given once at registration; every file reads them from there.
One timeline
Every submission, check and signature in order; nothing sent is overwritten.
