  • Read the table as a shortlist, not the whole decision.
  • Model AI and channel usage before trusting the headline plan price.
  • Run the final choice against real tickets, not an empty demo workspace.

What to validate in a trial

  1. 01Connect the main support channel and import the top articles or macros.
  2. 02Route at least one normal week of tickets through the workspace.
  3. 03Measure how quickly the team understands ownership, priority, and next action.
  4. 04Review AI-generated drafts or resolutions for source quality and tone.
  5. 05Compare the expected monthly invoice using real seat, channel, and AI usage assumptions.
