I also believe that clients will pay more for better reporting. The current issue of Inc. magazine makes that point in an article, "How Would You Make Over the U.S. Postal Service?"
Sean Harper, Co-founder, TSS-Radio, had to say:
"When it comes to shipping small packages, the USPS is cheaper than its competitors and offers comparable and sometimes even faster delivery times. However, since it doesn't offer reliable tracking, we pay a premium to ship most of our packages with UPS. If the USPS tracked packages as well as UPS, it could capture a lot of business."Reliable tracking is another way to say reporting. The USPS does offer tracking that you can pay for, but I believe it's not available for every type of shipping.
