Invoice immediatley. When you send it, tell the client you are sending it,
and that you could really use the money since this is how you pay the bills.
Call the client back in a few days to see if they got it. If they haven't
then offer to fax it to him. If they have it ask them how long it
For comparions, a nice aspect of j2ee applications IMHO is the
application server tends to be more general. ie. the application
server is not just the web server (as it is with mod_perl). I've found
j2ee features such as message beans, queues and such especially useful
for back-end work.
