service period in recurring invoices
in germany we have to define the service period in invoices.
therefor it would be great if the start date would be automatically set to the next (following) start date.
Recurring invoices really need to tell what the timespan is of the periode that the client is billed for. Know the clients have no clue at all, and invoices from last year look nearly identical to the one from this year!!
Not only in Germany, it would be usefull all around the world !
