It depends on the platform. Most, like SnapDocs have Accept, Decline AND Counteroffer options. You can always counteroffer if the fee is too low. In the example that you gave I would assume that the $85 fee includes printing 2 sets of documents (one to sign and one to leave with the borrower, because the majority of signings require that you print documents) and no faxbacks (because it is normally stated in the notification if fax backs are needed). So, if you are ok with the $85 fee including printing and no faxbacks then accept the offer, and then if you are selected immediately verify with the contracting company exactly what is needed and renegotiate the fee at that time if you require a higher amount to provide the service that they are requesting. Or decline the assignment at that time if they are unwilling to meet the amount that you want.
