Preparing event exports for a CLV assessment

Clean exports shorten a customer lifetime value assessment more than any fancy chart. Before our kickoff we ask for a short list of fields and a note on timezone.

Minimum useful fields

  • Anonymous user or device key
  • Install or registration timestamp
  • Acquisition source as your team defines it
  • Purchase or renewal timestamp and net amount
  • Refund timestamp when applicable

Timezone and currency

Pick one timezone for the study—Asia/Bangkok is common for our local clients—and state the currency of amounts. Mixing USD cents with THB baht without a flag creates false payback stories.
