We've had a few clients, for especially for pipeline/nontraditional projects, request access to the portal after the engagement end date to keep track of candidates we submitted. That said, leaving the project open messes with the accuracy of our data, so we'd like to still be able to close them when the engagement ends or we make a placement. This could be a passive revenue generator for us, as candidates we submit are subject to the terms of our agreement for an additional period of time and so, if a client chooses to hire them for another role, we would still be owed a placement fee.
