Humans (accountants) are non-deterministic, so unsure if an LLM would be better or worse if we threw more effort at the problem. But in general, I tend to side with the "lets leave the math to purpose built models/applications" instead of generalized LLMS. LLMs are great if you are just aiming for "good enough to get through next quarter" type results. If you need 100% accuracy, an LLM isn't going to cut it.

Human accountants also have a very important property: liability. If a certified accountant told me to do X, I'm covered (at least to the point they would assist in recovering, or I can get compensation through their insurance). If LLM tells me, I'm in a bigger problem.

Most small businesses cannot afford CPAs for everyday tasks. At best a CPA signs off on the annual summaries. Most day to day work is done by bookkeepers who are not CPAs.

In my area (Vermont) the going rate for a good CPA is $200/hr. Bookkeepers are $20-30/hr.

I'm sure that any accounting trick that an LLM can think of is something that is also used by some shady human accountants. The proper response should not be to avoid/prohibit AI but to improve the validation mechanisms.

No, I think in this particular case the proper response is for honest companies to avoid any systems which invent nonexistent transactions to reconcile books. Most businesses don’t want to misrepresent their books, irrespective of the existence of shady accountants.

It is really really common for book keepers to create transactions to reconcile books. Not okay, but ‘journal entries’ are pervasive.

Hey all, member of the benchmark team here! The goal for this project was to see how LLMs well could do bookkeeping without an overly opinionated scaffold. We gave them access to processed transaction records and code execution tools, but it was up to them to choose exactly how to use those. Claude and Grok 4 did reasonably well (within CPA baselines) for the first few months, but tended to degrade as more data came…

It's a start. The world needs a better way to handle bookkeeping, and the existing tools sure aren't cutting it. Bookkeeping for my small business runs into the tens of thousands of dollars every year, and the amount of human error associated with processing assorted ecommerce and other transactions is astounding, even after extensive planning and SOPs. The other pain point is Quickbooks. The tool is so sprawling and…

How small is your small business? My book keeping expenses are $120 a year, the cost of excellent saas software. I’ve found double entry books one of the most beautifully simple, yet powerful ideas I’ve ever come across. It’s hard to imagine how a balance sheet could be improved or disrupted. The balance sheet for my small business is the same as Apple and Alphabet’s and that still blows my mind.

There is "LLM misinformation" insurance, a very new branch of cyber insurance.

If the "extremely precise requirements" can be cheaply and automatically validated, it's much easier to have the AI generate spam on a loop until it passes all the tests.

You're saying P=NP, I think.

Not to agree with GP, but I think it’s more accurate to say they’re saying “if validation is quick (to code), who cares how long a solution takes an AI because computation is cheap.”

They’re not really making any claims about how quickly the AI can solve relative to the validation, which is what P vs NP is about.
