When you CHANGE TERMS to update your price, does that get flagged as an update to the potential client? Do they get a notice? Does your proposal get moved to the top? Curious.
If you are already interviewing with the client (meaning they have accepted your proposal or you accepted their invite), then you'll be able to add a message when proposing different terms. If your proposal hasn't been accepted, the client isn't specifically notified if you propose different terms, they will see the new bid amount when they view your proposal.
