You've built two years of booking history in Calendly. Your clients know their timezone is saved, their preferred meeting duration is there, their notes about dietary restrictions sit in your booking records. Then you decide to switch platforms—maybe to something that handles WhatsApp or integrates deeper with your CRM. You log out of Calendly and discover the hard truth: your booking history doesn't follow you. Neither do customer preferences, timezone settings, or the metadata that makes rebooking faster. Calendly stores it. Calendly owns it. And Calendly won't hand it back in a format you can use elsewhere. This isn't accidental design. It's a retention mechanism—expensive enough to rebuild that most teams stay put. What Calendly actually exports (and what it doesn't) Calendly offers a data export function. It looks responsible. The reality is narrower. What you can get: A list of scheduled events (date, time, attendee name, attendee email) Basic event metadata (duration, meeting link if you added one) A CSV file you can technically open in Excel What you cannot get: Conversation history from your booking confirmation emails or follow-ups Custom fields you created (dietary restrictions, company name, project reference) Timezone preferences linked to specific contacts No-show data or cancellation patterns Notes you added to individual bookings Recurring client preferences ("always book Tuesdays at 2pm") The exported CSV is a transaction log, not a customer record. It answers "what meetings happened" but not "who are my repeat clients and what do they need." Why this matters when you switch platforms Imagine you're a wellness coach with 40 regular clients. You've built Calendly over 18 months. Each client's file contains: Their preferred session length (30 or 60 minutes) The timezone they always book from A note: "prefers morning slots, no calls after 6pm" Booking frequency pattern (weekly, biweekly, monthly) A custom field: payment method already on file You export from Calendly and get a CSV with dates, times, and email addresses. You import into a new platform. Now you have 40 meetings with no context. Your new system treats them like cold bookings. You'll spend 10 hours re-entering client preferences because the data format your old platform used isn't compatible. Worse: if you're moving to a CRM-integrated booking system , your customer records stay disconnected. A client books a session, but their booking doesn't pull their contact history, deal status, or email threads from your CRM. You lose the connective tissue that made your old system efficient. The cost of switching platforms isn't just the new subscription—it's the hours you spend manually recreating customer context that your old system wouldn't export. Which booking platforms actually export complete data We tested export functions across six platforms commonly used by SMBs. Here's what each one hands you when you leave: Acuity Scheduling: Exports bookings, custom fields, and client contact info as CSV. Notes attached to bookings come through. Timezone data is included at the event level, not the contact level—you'll need to manually link it back to client records in your new system. Better than Calendly, but still a manual step. Setmore: Provides a basic booking export (dates, times, attendee). Custom fields are included only if you flag them in the export dialog—easy to miss. Conversation history from reminder emails is not included. Timezone preferences do not transfer. Square Appointments: Integrates with Square's ecosystem; exports booking history and basic client fields. If you're moving to a non-Square system, the export is serviceable but incomplete—custom fields don't always map, and timezone logic requires manual rebuild. If you stay in Square's world (payments, POS, etc.), the handoff is cleaner. Calendly: As described above. Minimal export. Designed to discourage migration. Outlook / Google Calendar + Zapier: If you're booking through calendar providers directly, you get event data but no booking-specific metadata. You'll need a third-party tool like Zapier to export to CSV, and you'll still lose custom client fields. This setup fragments data across multiple systems. Orin Bookings : Exports bookings, customer contact records, custom fields, timezone preferences, and notes as structured CSV and JSON. Because booking is built into the same platform as your CRM , customer data doesn't fragment—bookings pull contact history and deal context automatically. When you export, you get the full customer record, not just the calendar event. Switching away means you take your complete customer file with you. The reusability test: Can you actually use the export? Exporting data is one problem. Using it in a new platform is another. A truly portable export must include: Custom fields with their logic intact. If your old platform had a "preferred time of day" field with radio buttons (morning / afternoon / evening), can your new platform impo
