Items here are not assigned to any vendor yet — usually because they were shared from WhatsApp / Mail, dropped into the OneDrive watched folder, or couldn't be auto-clustered. Pick a vendor for each, optionally tag a product code, and they'll move into that vendor's timeline.
Inbox empty
Nothing pending. New items arrive here when you share a file from WhatsApp / Mail to "Sourcing", or when the OneDrive watcher picks up a new file.
