I have installed A2Billing 1.9.4 and set things up in such a way that an invoice is created on a specific day.
I have also set up e-mail so the client can receive the invoice via e-mail.

1. I would like to send an e-mail automatically on that specified day to the client with the invoice attached to it – not just that which
is put into the "invoice_to_pay" e-mail template.
2. I would also like to have the report of the month’s calls included in the invoice.

Can someone advise me on how to do this?

take a look at A2billing/Cronjob/a2billing_batch_billing.php file.
