Every accounting workflow has a simple requirement that "AI agents" often struggle with: the same inputs must produce the same outputs, every time, in a way an auditor can trace. If a reconciliation runs twice and returns two different totals, nobody can defend either number. That is the core problem we set out to solve.
Most AI accounting tools run every transaction through a language model. The model looks at the data, makes a judgment, and returns an answer. It can be impressive — and it can be wrong in ways that are extremely hard to spot, because the output is different on every run and there is no deterministic record of how it was produced.
For a bank reconciliation, a month-end close, or an AP process, that is not acceptable. These are processes where the audit trail matters as much as the result. If a client asks "how was this number produced?", the answer should not be "the model decided it."
Our pipeline runs the bulk of the work as SQL against a DuckDB engine. Matching, classification, and validation are deterministic queries: the same query over the same data returns the same result, on demand, every time. A model drafts each query and a person on your team approves it before it is frozen for replay; a schema change or a new period forces a re-review. That gives you three things at once:
Beyond drafting queries, the LLM is reserved for genuinely ambiguous cases the rules cannot confidently resolve — the transactions where no deterministic rule can decide, and a human would need to look anyway. Those calls are narrow, targeted, and logged like everything else.
Because execution is SQL-first, the chain of custody is concrete. Every SQL query, every LLM call, and every human approval or override is written to the audit trail. When an auditor asks how a figure was produced, the answer is a specific, reproducible query — not "the model did it."
This is the difference between software that supports accounting work and software that *replaces it with a black box*. The workflows we build are designed to be verified, not trusted on faith.
We put our money where our mouth is: our public benchmark publishes the inputs, the prompts, and our own failures. On the aviation billing case, 12 of 12 leading AI models got the total wrong; our engine matched month one exactly and missed month two by $707 — published, with the root cause. Read the methodology and reproduce it yourself.
If you are evaluating accounting automation, ask the vendor one question first: *do deterministic checks run before the LLM, or is the model doing the whole job?* The answer tells you whether you are buying repeatability — or a guess.
