If you'd like to gather extra information from a client during the booking process, Check Cherry makes it easy to do.
Just click on Manage --> Booking Engine --> Extra Questions.
Type in your question, select whether to show it during online booking or only on lead forms and internal uses, and select which packages this question applies to.
If you select only during online booking and proposal, when a client books online and selects one of the packages you have applied this question to, they will be asked the question during the online booking process.
If you select Only for lead forms or internal use, then your question will be available to add to lead forms and in the Additional Info section of each booking.
