I consistently have this issue. All of my recurring invoices are NOT checked to automatically send. Quickbooks still sends the invoices. Not for all clients though. It is random. I will even go through and make sure the box is NOT checked prior to the date the invoice is set to generate and yet it will still send. I have contacted support and unfortunately no resolution, all I have been told is to be sure the box is not checked and it took over an hour for them to give me that final resolution. There is obviously a glitch in the system. Also, when you choose to update changes made to the invoice itself it will automatically check the auto-send box in the recurring template. but it doesn't happen every time.
