Automatically create invoice of unbilled/logged tasks

Is there a way the system can automatically, on the 1st of the month, check for any unbilled/logged tasks, create an invoice and email to client? If there are no unbilled hours for a client, no invoice is generated.

I have several clients where I add hours throughout the month. I tend to “forget” to go in and invoice for all unbilled hours. It would be great if the system could do this for me.

Thanks.

Sorry, it isn’t supported
