Project Inbox
Houses all of the ITBs Riffle has found for your team; think of them as your inbound leads.
Occasionally, if Riffle cannot find a source project, you will also see addendums & GC comments.
Opportunities
Houses all of the ITBs your team has accepted.
Includes only bids/projects your team wants to actively pursue & track.
The difference
Riffle works to keep the "noise" of messy ITBs separated from your real opportunities.
