Modelling Unstructured Financial Data for Audit

Audit evidence is at its weakest when a system documents decisions but not the inputs behind them. Unstructured documents are the classic case: the invoice is a file; the obligation it proves is anywhere.

A canonical record, not a template match

The durable answer is a canonical document model: every source document maps into a typed record with fields, parties, line items, amounts and a reference to the original file. Templates can hint, but the model is what carries meaning.

Confidence you can audit

• Every extracted field carries a machine confidence and a human resolution when it is low
• Currency, date and amount validation run against what the document itself says
• Changes to the canonical record are versioned, never overwritten

Once the model exists, downstream systems — ERP integration, compliance screening, consolidation — consume the same typed record instead of re-parsing the file. The auditor follows one path from control to source document.
