This happens to me a lot, but it's basically a kind of technical debt. Most of the time the upfront time investment to automate something properly versus doing it manually is hard to justify. Especially if it's a task that only I understand and now I need to document the problem and the automation instead of just the problem.

Business logic doesn't make for elegant APIs that I can hide behind a script and throw on a server, even if it's repetitive or tedious.
