Flux analysis

Period-over-period variance with commentary that can only quote figures actually in the data.

Close → Flux analysis.

Which accounts moved materially between two periods, and what moved them.

Variances are selected on a dual threshold — a percentage and an absolute amount — so a 400% swing on a $12 account does not crowd out a 6% swing on a $400,000 one.

Each variance is then decomposed deterministically: which vendors, customers, projects and entities actually account for the movement. Commentary is drafted from that decomposition and may contain only figures present in it.

That constraint is the point. Asked why travel expense rose, a model will happily answer "due to the annual sales conference in March" — fluent, plausible, entirely invented, and about to be signed off by a controller. Here, if the cause is not in the decomposition, the commentary does not claim it.

Commentary is drafted for review and approved by a person before it goes anywhere.
