The intent of the Interested Vendor List (IVL) feature is to collect a list of vendors interested in competing for the opportunity or vendors interested in subcontracting opportunities.
The contracting officer is the only person who can determine whether to include an IVL and the view settings for an IVL.
Both contracting officers and contract specialists can view an IVL. Vendors responding to an IVL must be logged into SAM.gov to respond.
