The contact forms are perfect if you like to gather a lot of extra info at once, for example, with a new client. You can send them to all your new clients and they are totally configurable so you can choose the questions.
Contact forms can be embedded into email templates or added to the message buttons, making gathering info super efficient.
Check-in forms are associated with a particular appointment and are perfect for gathering last minute emergency contact info or doing a health check with the pet on arrival, for example.
Check-in forms are brilliant at helping you to easily upsell spa packages too, as they can be designed to lead a client through all the great options for their furry friend.
