With every service there needs to be a feauture which can be set to default requesting the customer to add specific information before a booking can be made. So for my business my customers require me to attend different properties to conduct my services. Each time they select a service they will then need to enter the property address they want me to attend, enter the contact details of the person living/moving into the property, location where to collect the keys from and any extra notes. If the requested information is not completed the booking cannot be made. This information will also need to be visible to the customer when viewing their bookings.
