Hi The_Doc
Apologies, for the confusion on my previous response. With what it sounds like you are asking, you would like to have 1) invoice created automatically on a monthly basis 2) have a day of the month it is sent out.
So you can either have the system remind you to create it, or have it record those transactions automatically.
But this would just create the transaction. You would then need to set an invoice reminder so customers would get an invoice at the specific date of month you prefer.
So the recurring invoice creates it, then the invoice reminder you set as a specific date emails it.
Here is more information on both of those features:
Recurring Transactions
Invoice Reminders
Please let me know if you have any further questions.
