I am adding invoices from 2007 into Billings and want to know if there is a way to change the 'invoice sent on' to a specific date rather than the current date.

I am also interested in this. I am adding my information from 2007 and it automatically sets the date of a sent invoice to the current date, even if I set the invoice date myself.

I too would like to know how to do this. While I enter invoices and payments with the correct 2007 year, Billings seems to only watch the 'Sent On' date for the invoice when creating reports. There must be a way to get past this? Why have an option to add a date to an invoice if it is ignored?
