Too many to list here, but one of my most useful ones is a Python script to help pay out affiliates. It crawls through monthly CSV files provided by my payment gateways, finds sales and returns by a specific affiliate, calculates what I owe them and returns a dollar amount, a sales break down for each course, how to send it (paypal, wire, etc.) and who to send it to. It's nice because it takes around 2 minutes to payout everyone each month with a very high confidence level in the results. Prior to the script, it was a stressful work flow with many chances of human error. I only did it once before automating it. Another script I use helps me invoice my freelance clients each month. It's a Bash script and is open source https://github.com/nickjj/invoice https://github.com/nickjj/invoice. It saves me a ton of time every month since I can calculate how much I need to invoice folks in a few seconds with it.
