Please add an option to select in Sales preferences, so when creating an invoice it defaults to today's date, not the last entered date.
"Default Date Setting/Preference"
It makes sense. For the most part we require the invoice date to be the day we are actually doing the invoice. Yes, sometimes invoices need back-dating, but only sometimes. I can't tell you how many invoices I've done without realising the date is not "Todays date". At the very least the program could pop up a warning box asking if we're sure about the date not being that of today.
