For the past few months I’ve used Duotrope to track my fiction submissions to various markets. Previously I was using Google Sheets, with different sections of one large spreadsheet to track stories and submissions, markets, and responses. The sheet worked great for a long time, but once I had over twenty stories, hundreds of responses from publishers, and dozens of markets to track, the spreadsheet solution became unwieldy. I started to miss things, and in one cases submitted a story twice to the same publisher. I also started to submit fewer stories, simply because of the difficulty in using the spreadsheet. Time for a new solution!
