Supplier collection works best when each request explains what is missing, why it is needed, who can see it, and when the task expires. Broad shared folders make confidentiality and completion hard to audit.
A practical preparation workflow
- 1
Create a task from specific case gaps.
- 2
Collect bounded fields, files, and plots.
- 3
Freeze the submitted response and show buyer progress.
What to check
- Task scope and expiry
- OTP and replay protection
- Autosave conflict handling
- Confidential upstream routing
Keep this limitation visible
The Supplier Portal collects evidence; it does not authenticate supplier statements.
