There have been many advances in the field of freelance writing over the last few years: for most publications it is no longer necessary to send in an SASE (self-addressed stamped envelope) query; electronic payments outpace snail mail checks; social media has made it easier to connect to other writers and editors, etc.
The business side of freelance writing has gotten easier with more online applications streamlining mundane tasks many writers loathe. Shoeboxed is one great app that moves shoeboxes full of receipts out of the closet and into cyberspace.
