What is Amazon’s invoice defect rate (IDR) and how does it work?
Selling on Amazon is about much more than just fighting for rankings and optimising ad spend; it is fundamentally about meeting strict performance standards. One critical metric you cannot afford to ignore is the Invoice Defect Rate (IDR).
