I got annoyed of all the crappy invoicing tools, so we built something custom for https://m9rx.com/

I've also had to build a bunch of small tools since we don't want to be locked into crappy cloud services.

We also funded a small improvement into hledger, because we are trying to use a % of our income to vote with our feet.

If people really want to use our invoicing and other small tools, we'll consider open sourcing them or selling them for cheap. Not sure if this is useful or a distraction.
