> Source: Used to run an e-commerce company that shipped up to 2 million packages annually. Once we optimised shipping and processing, customer service inquiries and complaints dropped dramatically, and customer trust / sentiment skyrocketed.

I used to work at company that shipped ~30k packages a day. I’d say 90% of customer complaints were about the delivery delays, and only 10% about the rest. It was really hard to optimize because we had 1M products and were using just-in-time logistics with very little inventory. This is a specific market that Amazon hasn’t really entered yet, but when they’ll do they’ll crush everyone.
