Hi, everyone...

I've incorporated the comments everyone offered on invoicing into a new
document, which seemed like the best way of retaining comments and local
practice details while keeping the working document as clear as
possible.  The new document is at:

https://docs.google.com/document/d/1V_PeTvrVMzxIwogcrmjlk7mwLPN9k7-rDf8m1SWe7sk/edit?usp=sharing

Hopefully I've appropriately addressed the feedback provided; please let
me know if I've missed or misstated anything or if you have questions
about anything in the document.  I'd suggest that we discuss the
comments I've added in an upcoming call.

Best,
Kathryn
