Replaced on the GRAJ protocol. One fee. 195 countries. Join the protocol.
A replacement is two movements and one commercial decision: something comes back, something goes out, and somebody decides who pays. Systems that model it as a single event lose the inventory on one side and the cost on the other.
The returned item is stock with a condition and a disposition — resell, repair, scrap. The replacement is an outbound shipment with its own cost. Netting them into "a replacement" makes both invisible.
A defect, a wrong item shipped and a change of mind are three different answers, and deciding the policy in advance is what stops each case becoming a negotiation the customer wins or loses on persistence.
Individual replacements are noise. The same product replaced repeatedly is a quality signal, and it is only visible if the reason was recorded rather than the cost being absorbed.
Designed, not built. Returns exist as records on the protocol; a replacement flow that links the inbound and outbound movements and their cost does not.
