Every month, same ritual. Open the browser, navigate to the invoice generator, update the date, bump the invoice number, change the line item description, download the PDF, open my email, attach it, send it.

It's maybe five minutes. But it's five minutes of pure purgatory.

So I built my own. And I kind of love it.

A little context

I'm a Senior Support Engineer; I'm not a full-blown developer, but I know how to build things — and there's always the good ol' Claude Code to help me ship faster. This project started as a weekend idea and turned into something I actually use every month.
