In prepaid retail, returns are the exception — most buyers keep what they paid for. In cash on delivery, refusal at the door is built into the model. A seller running at a 60% delivery rate is sending four parcels back for every six that land.
That flow has to be designed, not improvised. Parcels that sit in a corner of the warehouse are capital the seller has already paid for and can no longer sell.
Returned orders come back to our warehouse at no extra charge — only the delivery attempt is billed. Units are inspected and put back into your available stock, and the reason is recorded against the order so the pattern is visible rather than anecdotal.
