A SWITCH WITHOUT SURPRISES

Take your real workflow into the trial.

  1. Write the reason for leaving. Identify the failed requirement, its business impact and the acceptance test for the replacement.
  2. Price an actual month. Include staff, resources, booking revenue, messages and any package-related charges.
  3. Test the awkward case. Recreate a calendar conflict, an overlapping rental or the final group seat, then cancel and inspect the payment outcome.
  4. Reconcile before switching. Confirm future reservations, customer notices and outstanding balances with the destination vendor. Keep the old records until the transition is checked.
