Yep! Client records can be created individually, imported from another system or spreadsheet (CSV), or they're created automatically when an appointment is scheduled. If the first name and last name are different than an existing client, then a new entry will show up in your client list.
Select to "Edit" one client record to match the first name and last name to another client record. Select to "Save Changes", and this will automatically merge the two clients together.
Have two different clients with the same name? Contact Acuity support, and we'll be able to help!
