Sometimes it may be necessary to resubmit a Job back into QuickBooks®. If this is the case, simply delete the Invoice checkbox in the Door Jobs > Add/Edit Jobs/List.
This will ask you a question if you are sure you want to submit it. After hitting yes, you will see that the date/time it was exported also is removed.
Doing this will allow one to resubmit that Job back into QuickBooks®.
