Solid job unearthing the numerous billing system challenges (almost triggering PTSD from prior experiences interacting with such systems...). While I haven't fully checked out the details of the solution you offer, I'm excited to see builders embarking on building better solutions :huggingface
I occasionally get PTSD flashbacks from my time maintaining a home brew billing system.
That shit is hard. There are so many ways to fuck it up because you didn’t know what you were doing. The list of unknown unknowns for a billing system are huge unless you are an actual expert in billing, which you aren’t and neither is anybody in your team.
