We charge clients a monthly hosting fee that is automatically charged to our clients credit card via Authorize.net 

While we have all of these clients setup via Zoho books to automatically receive an invoice - can the following be done: 

1. The email is automatically sent out monthly, with no need for us to manually send out the emails (by default it's saving a draft not automatically sending it out) 

2. In many cases, these invoices are already paid. We would like the invoices to show paid, not offer the option for the user to pay with the balance. 

3. This one may not be possible. Instead of setting up the recurring billing with auth.net directly - can we use zoho books to automatically send out the invoice on the same day of the month but before doing so automatically charging the credit card on file via authorize.net Zoho integration? 

Thank you.
