Hello,
There are any way in database or application to delete Deleted Invoice?
Thanks
Nevermind, was a problem with my browser cache 
Does not work for me. What to do in this situation ? Month after month “deleted” records will clutter database unspeakably.
It cannot be solution to purge clients, etc. It is extreme option.
