## Registration

After entering `Invoice Number` and  `Invoice Date` please use `Check` and the system will check whether the corresponding invoice has already been recorded.

If there is an invoice with the same data, then the invoice will be displayed. With "Yes" the new invoice can still be entered and with "Cancel" the process can be aborted.
If the invoice number has not yet been entered by this date, a search form will appear.

All attachments will be stamped. After stamping, the stamp is issued again as an info box.
