If your company ships less than 20 packages per day, you can easily fulfill and ship them on your own by using the software and services from major shippers such as the U.S. Postal Service (USPS), UPS and FedEx.
Software from these carriers can be used to process domestic and international shipments, handle routing and billing, print labels and pick-up records, track packages, order supplies and view time-in-transit options. Customers can track shipments through companies' Web sites; find estimated delivery times; and compare, price and select the various shipping services.
Options offered for basic ground delivery run from overnight to seven days. "Two to three days" is becoming the norm for residential delivery.
