If you notice a gap in the sequence of your system-generated order numbers, don't be alarmed. This does not necessarily mean that there are missing, deleted, or voided orders.

There are many use cases for the numbers that are created by the system, and not all of them are uniquely allocated to new orders. Some examples include: A number is applied to show the payment form at checkout; when the form has not been submitted; or when the customer card has been declined for online payments, and the system then allocates and sends the next invoice ID number in line for the retry. Additionally, the invoice ID number advances to the next in line when there are member sign-ups, because the payment processor also needs unique IDs for zero amount authorizations.
