In E-commerce, a 4.5-star rating vs. a 4.8-star rating is a massive difference in revenue. If a customer receives a damaged item or the wrong size, their first instinct is to leave a bad review. Change their path by including a 'Something Wrong?' QR code on your unboxing card.
The customer scans the code, sends a photo of the issue, and you offer an instant replacement or refund. This 'heroic' customer service prevents the 1-star review and often results in a glowing review about your brand's integrity.
