An agent sitting on unreconciled data does not give you fewer wrong answers. It gives you confident wrong answers, faster.
Most of what is being sold as finance AI assumes the boring work has already been done: that the chart of accounts matches how the business is run, that master data is maintained in one place, that a definition means the same thing in two reports. Where that is true, these tools are genuinely useful. Where it is not, they industrialise the confusion.
So we start where we always start. Fix the data and settle the process, then automate the parts that are repetitive and rule-based, and only then hand judgement to something that learns. That order is not caution for its own sake — it is the difference between a pilot that scales and a pilot that quietly gets switched off.
