Payment Method DirectDebit - Invoice can not be sent at invoice date automatically...?!

Payment Method DirectDebit - Invoice can not be sent at invoice date automatically...?!

We are using Zoho Subscriptions for our SaaS-Business in Germany.

We understand, that the function of sending invoices automatically to customers is linked to the successful payment of the invoice, but concerning to legal and ususal reasons (in Austria, Germany, Switzerland and most of the countries in EU) the invoice has to be sent on the day or the day after invoice date to customers – it must not be addicted to the payment and for example,  when payment was not successful, no invoice will be sent…


When using the payment-option Direct-Debit this would mean, that the invoice would be sent 7-10 days later than the invoice date, that is not acceptable.
The solution should be easy, there has to be created a new mail notification "ACH payment initiated with attached invoice pdf"
Please add that to your Roadmap - Thx!
