We need the option to have invoices emailed for Squarespace charges and to be able to choose the address they are sent to for each different site on an account.
This question was raised once before, but was closed with the reasoning that (paraphrased)
"It sucks that you can get your invoices emailed, but you do get a handy notification email before being charged to let you know the charge is coming"
I find this an unacceptable response. I have designed many sites for different people and I need them to be automatically sent invoices when they are charged by Squarespace.
