Event Organiser's Migration & Data-Rescue Checklist (fill-in, 2026)

A fill-in worksheet for event organisers whose ticketing service has shut down. PassMarket closed on June 30, 2026, and its ticket management tool is announced as available until August 31, 2026 (planned). The sheet covers what to rescue before that deadline (attendee records, survey responses, revenue and payout records, event page copy, ticket configuration), an inventory of the channels through which you can still reach attendees, a formula and worksheet for calculating the effective cost of a new platform yourself, and the steps to launch a first event on it. Anything the official announcement does not state — when in-service messaging stops, the export specification for attendee lists and survey data, the timing of payouts — is marked "to be confirmed" rather than asserted. It does not rank providers; it supplies the formula and the checklist.
