eInvoicing in Italy

Dear Joomlapolis,
starting from 1th january 2019 there will be mandatory electronic Invoicing in Italy. To issue electronic invoices to professionists or companies we'll need two additionals optionals invoices fields:
1. a PEC email address (certified e-mail);
2. a code identifier (unique and related to company - is different from VAT)

and sure fiscal code and/or VAT.

Could You suggest a solution?

Thanks!

Please see attachment (woocommerce example)

Best I can suggest is to collect that information at time of registration then within CBSubs > Settings > Display > Invoices substitute the fields you're using to collect that information into the invoice display.
