Can I check which vendors started a submission but did not finish?

Bonfire gives you visibility on Vendors' Submissions including the proposals that were not submitted.

If for any reason you need to take a look into the Vendors that started a Submission but did not submit at the end, you will be able to view this under the Work-in-Progress Submissions located on the Submissions page:

By expanding the view to show the suppliers, you will be able to view details such as:

• Supplier - The Supplier's Name
• Created - The day they started their proposal
• Progress - How far they got on completing the proposal
• Type - shows if the Submission was either External (made by the Vendor) or Internal (made by the Project Owner).
