@dascpa I'm not suggesting how to run your practice, just trying to bring you up to date on today's shipping terminology.  "Ground Advantage" is what the United States Postal Service used to call  First-Class Package, Parcel Select Ground, and Retail Ground    It is not the United Parcel Service "Ground" service that you quote.  USPS is not UPS.  Apples are not oranges.  Try USPS Ground Advantage, your clients will like it because it costs less for the same delivery time.
