Returns change more than revenue
A return can affect inventory, fees, settlement timing and the customer outcome. Counting returned units without following the related financial entry leaves part of the story unresolved.
Keep event types separate
A customer return, RTO and cancellation represent different operational situations. Keep their labels intact wherever the marketplace report provides them.
Review patterns at SKU level
Repeated reverse movement around one SKU can point to sizing, image, description, quality or fulfilment issues.
