it appears your response answers the question how to send invoices in Batch but not the original question "how does the SEND LATER check box function work in the invoice section?"  can you please help with the original question... my understanding is that when you enter an invoice date and check the "Send Later" box then the invoice SHOULD send the invoice AUTOMATICALLY on the invoice date but that's not what I'm experiencing.  I would appreciate if you can explain how to use the Send Later function when creating invoices correctly?

Thanks!!
