Prove retail transaction retention before the launch cutoff

Retention decisions become difficult when the same record supports operations, investigation, and regulated handling.

Deleting too little and deleting too much can each create lasting exposure.

I need the history when something gets disputed, but I don’t want my data handled carelessly.

Runs a small bottle-shop group using transaction reporting to investigate refunds and inventory discrepancies.

What pulls against what

  • data minimization vs. dispute evidence
  • launch deadline vs. classification certainty
  • centralized controls vs. operational access
  • automated catalog signals vs. verified lineage

What is at stake

Incorrect retention could create compliance exposure or erase evidence needed for disputes. The migration must be right before irreversible deletion begins

This is the setup. The work is inside.

Running it puts you in the room: the full situation and its constraints, stakeholders who push back in their own words, and the decisions that are yours to make. What you produce becomes a Day One Plan — work you can show someone instead of describing.
