I think there’s a difference between _wanting_ something to work and _needing_ something to work. Enforced standardized invoicing might be a very tidy and neat solution, but tidiness and neatness are not a good enough argument to mandate it in my opinion. There’s no end to the areas of our lives that could be regulated if that’s the standard we’re aiming for, and I don’t particularly want to live in such a uniform, straightjacketed environment.
