Alternative Billing by Lawyers

I recently began representing a client that is using a large law firm for all of its single-plaintiff employment discrimination cases.  The large law firm charges for its services for that client on a flat fee basis, with the fee determined based upon the stage at which the case is resolved.  My law firm serves as local counsel for the large law firm on a case in Utah and is paid on an hourly basis.  I have been impressed, however, with the large firm's creative use of alternative, flat fee billing.  Lawyers and law firms need to continue to implement alternative fee arrangements that will lessen and eradicate billable hours.
