A senior reviewer on every job
A junior reviewer checks each prepared job, then a senior has to check the junior’s review before anything is signed off, and that senior standard lives in a few people’s heads. The work runs across Xero, XPM, SharePoint and Karbon and none of them check each other, so a miss (a workpaper that does not reconcile, a document filed against the wrong template) only surfaces when someone senior happens to catch it.
An operating layer across all four systems that applies the firm’s own senior-review standard. The agent checks the junior reviewer’s work the way a senior would, sends it back to the junior reviewer with specific notes, and escalates only the calls that genuinely need a partner’s judgement. Deterministic checks reconcile the numbers, the agent reviews the rest, a human signs off.
