When the reservation is made and confirmed in the system, the guest will receive a confirmation email. In that email, there is a button that says "Add your info".
There is also a so-called Before start email that can be sent out from the Reservation module > Mailing > Before start. By sending this email, you are asking the client to finish online check-in, and at that time they can provide you with credit card details.
When the guest clicks on that button, they will link to the Guests platform, where they will provide details including name, email, address, and payment card information.
These details can also be filled in by guests at the time of online check-in.
