E-billing systems ring out the huzzahs for their systems’ ability to track the routing of invoices. Certainly, some bills involve review by more than one lawyer, because the work falls within multiple lawyers’ expertise. Here, routing capabilities might make some sense.
What I can’t imagine is that it is very common for a bill to be so large as to require sign-off approval by more than one lawyer. Most bills are modest, under $10,000, and most lawyers who are responsible for outside counsel probably have the sufficient authorization to approve them. Only an exceptional bill would require more than one signature. For this reason, I suspect the e-billing companies have hyped a need. (See my posts of May 14, 2003 on e-billing savings and July 30, 2005 on the focus of e-billing software.)
