Attachments are an easy way to add important information to bookings.
For example, you may need to attach a engineering certificate for a specific material lift on the crane. Just take a photo of the document or attach the file to the booking. It will be automatically saved to that booking and easily retrieved at any time.
Your traffic controllers or crane crew might also take photos of dockets or loads that turned up in an unsafe state, that way they are always saved to the booking and are easily retrievable.
