Let business set required fields for customers via a checkbox - for example, "Emergency Contact" might be a required field for their clients, but not for another business
From Justin Holland of Elevate Barre:
Have our customers enter more of their information online.
It is difficult to capture this information when people sign up online and if we need to contact someone in an emergency we may not have that information. I would say that should be put to the very top of the stack so business can capture the information that is needed. Thank you for your help and have a great rest of your day!
