- the invoices are created automatically (e.g. paypal) or by the shop owner
- cron job starts at 1 am
- System: Magento 220.127.116.11
- the cron shop will go through all invoices of the day before (0 am - 11:59:59 pm) and create a PDF invoice file for each invoice.
- the PDF invoice files will be placed on an external ftp server
- the ftp connection details can be in the source code because they will not change frequently. no admin frontend required.
- the implementation has to be encapsulated into a module (no coding in base or default)
