The Progress tab shows you the responses from the suppliers that have been invited to the event.
i. The first column 'Preview' shows whether suppliers have previewed the event and which suppliers haven't. Example above shows that all suppliers have previewed the event. Tracking this allows you to know at what stage of the event your suppliers are at.
ii. The second table 'Accepted Invitation' lists the suppliers that have accepted the invitation to your event. Example above shows that all suppliers have accepted the event. Accepting invitation denotes their commitment in submitting a quotation or bid for your event.
iii. The third table 'Submitted Submission' shows which companies have made a submission and which have not. You may contact suppliers that have not submitted and find out about the delay, send them a reminder or communicate with them via messages.
These tables help you keep track of activity and responses of suppliers and allows you to check their submission progress; if they did or did not receive the invite, did not accept the invitation or have not yet to submit the documents.
