A new client fills out your web form. Someone reads it, copies the same facts into Clio, drafts the same engagement letter from the same template, and emails the same follow-up questions. That's an hour of staff time, and the matter hasn't started yet.
Month end is worse. Prebills print, and partners sit with a red pen turning "attn to file, 1.5" into narratives that survive the client's outside counsel guidelines. Meanwhile the inbox holds three court notices with deadlines nobody has calendared and four clients asking for updates nobody has sent.
None of this is legal work. All of it is done by people you pay to do legal work.
