Invoicing question

Does anyone here invoice AHEAD of time? For example, invoice submitted on 10-01-2019 for services rendered through 10-31-2019 with net7 as payment terms? Also, the date on the invoice directly above the PO# is set for the last day of the service period which would be for
10-31-2019. When I submit invoices the system kicks back a confirmation email so I have that for my records to confirm date of submission.
This is what my client expects and I'm ok with it. They pay well and on time nearly all the time. I was just wondering if others do this too? And, I know its not common.
