Unfortunately at this time PracticeWorks does not have the ability to add the Notation "Return Address Requested" below the address on statements.
I'm Tagging @Anon so he can see this as a suggestion for the software.
Robin, do you send statements by printing them out yourself, or sending them electronically through us or a third party clearing house?
This would be a benefit especially for the occasional statement the offices are sending manually. It would be the exception of statements being mailed by the practice although this would be very helpful.
