The shipping industry is full of its own unique terms and acronyms which can sometimes be confusing to those who aren't full-time members of that industry. Add on top of that the unique terms we use in the SaaS (Software as a Service) industry and even EasyPost's own unique terms and culture and it can be enough to make your head scratch.
