My office in NJ handles intake, scanning, printing, mailing (at PO across the street).... If I have questions, I call the client at my convenience.  If not, returns are completed and returned by mail, pickup in office, or portal....  pretty seamless....   I do have occasional clients (requesting in person meetings.... )  Thats not a problem either .........  I'm in Fl and less than a 20 minute uber from the airport...
