How do you make customer address a mandatory field they supply when booking?

[BalloonBoutique]

I take bookings on square appointments for customers either to come to me for collection or I go to them, however I want to start taking their address as part of their booking process, so that I can send a contract with their address included. 

How can I do this?

Hi @BalloonBoutique, welcome to the Seller Community 🙂 

Apologies for the delayed response on this. 

From your Square Dashboard > Appointments > Settings > Appointment Preferences - what setting do you have enabled? 

If for Where do you accept appointments?  you have At both my business and the customer‘s location enabled, it should create a field at checkout for your customers to input their address. 

Let me know how this looks for you.
