Auto capture credit card question

[badrocks]

My client want to do an auto capture to the credit card they have on file. Auto capture works fine for recurring charges like hosting. This client is being charged for billable hours. At the end of the week I create a billable time entry for the hours and set it to invoice on the next cron run. The due date by default is set to the date the item is created. The next cron run and the invoice is created but there is no attempt to capture. I'm guessing that this is due to the fact that I have my automation settings set to attempt capture 0 days before and only attempt once. I'm trying to figure out a solution to this. Is there any way to make it attempt capture when the invoice is created if it's due? If not, is setting it to retry capture again one time one week later and setting the first reminder to 8 days the best solution? Will that solution work?
