You might be overthinking this one.  Just enter whatever date you wish as the invoice date instead of the date on the invoice.

Thanks! So the vendor invoice date in the system is different from the actual invoice. 

That is what you indicated you wanted.

The program uses the date field on each data entry screen to determine where the entry shows in the reporting.  If you use an October 2023 date now, your previous reporting to management will be out of date.  If you enter a Nov 2023 date, it will show on the Nov reports.  When doing this, I always indicated on one of the description lines when the original invoice date was and why it was changed.

Great advise. Thank you.
