If I have already mailed in an application with a check based on the net premium instead of gross, what is going to happen?

Whether a policy is Issued or placed under a 60 day binder, TWIA will mail your office a 30-day invoice representing the gross premium minus the net payment received (in most cases the amount invoiced will be the commission withheld by the agent when the application was submitted). If the invoice is not paid, cancellation of the binder or policy will follow.
