How do I import my existing bookings?

Setup → Import bookings: spreadsheet or Google Calendar.

Open Setup → Import bookings.
Choose Upload a spreadsheet (CSV or Excel), paste your Google Calendar secret iCal address, or Upload an .ics file.
Check the preview: customers, addresses, services and cleaners are matched by name; repeats become regular cleans.
Confirm the import.

No emails are sent for imported bookings. If something went wrong you can undo the whole import from the same screen. Importing the same calendar again only adds new bookings.
