Returns are a profit leak — not just a logistics problem

Most brands know their return rate. Few know which SKUs are bleeding money and why.

Without Retenza
  • You see a 15% return rate — but not which SKUs cause it
  • Return reasons are vague ("didn't like it") or missing
  • Ops fixes symptoms; nobody tackles root causes
  • Revenue leaks compound quarter after quarter
With Retenza
  • Every SKU ranked by returned revenue — worst offenders first
  • AI classifies root causes from free-text return comments
  • Prioritized action plan: what to fix, for which SKU, and why
  • Exportable dashboard you can share with your team today

What you get

Everything you need to turn return data into retention decisions.

SKU Ranking by Returned Revenue
