Jimmy,

You are right, invoices should be sequential, without gaps. Because of this, I don't think an invoice record should ever be deleted. If an invoice is printed, and the user deletes it, it should in reality be VOIDED...just like you would a check in your checkbook. The record should remain on file, with a zero amount, but marked as voided. Also, if you keep hardcopy invoices, the invoice should be printed out in its voided form and kept with other invoice copies.

Just my $.02.
