LLMs by their inherent nature cannot be relied on to be true and correct, which by coincidence are the only traits that matter in accounting.

If you want better software, then sure, maybe a coding assistant can help you write it faster, but when it comes to actually doing accounting I would not rely on an LLM in any way shape or form any more than I would do so for law.

Bingo! You found the prize! Putting tech that is prone to hallucination in charge of anything that has serious consequences when it's wrong is a terrible idea. You do not want hallucinated payments or receipts, or legal citations. You want these things to be both true and correct, EVERY TIME.
