You asked
Does it replace the clerk?
The short answer
No. It makes the clerk's job possible to hand off. It puts the procedures into the system, so the office keeps running and a new clerk can do the work without decades of memory.
The job stays in your hands. The software carries the deadlines and the steps, and a person still runs the office.
The test that it worked is simple: a successor completes a real case, start to finish, unassisted.
