Learn how to validate figures, link audit evidence and detect inconsistencies across financial documents with AI.
Does ai/numbers only work on financial statements?
No. ai/numbers supports financial statement review, regulatory reporting validation, M&A due diligence, internal control assessments and any audit workflow where figures need to be validated against supporting documentation. The underlying engine — identifying figures, mapping them across formats, checking consistency — is the same regardless of the document type. The use case is broader than the financial-audit workflow it’s best known for.
What is ai/compare and how does it work with ai/numbers?
ai/compare is dnl’s document comparison module. It identifies changes between document versions so audit teams can focus on what changed rather than re-reading entire reports. When a client provides an updated financial statement or sustainability report, ai/compare highlights the differences, ai/numbers re-validates the affected figures, and ai/checklist re-opens the disclosure checklist items that the changes touch. Version control and change tracking are built in.
How does ai/numbers support disclosure consistency checks?
ai/numbers runs four kinds of disclosure consistency checks: mathematical (do the totals add up?), internal (is the same figure consistent across all places it appears in the report?), external (does the figure match the supporting documentation?), and prior-year (how has it changed?). Each check runs automatically across the full document set, and any discrepancy is surfaced for auditor review with the source references attached.
Does ai/numbers process Excel and PDF files?
Yes. ai/numbers processes both structured and unstructured formats, including Excel files, PDFs and report tables. It identifies figures consistently across formats — the same number in an Excel schedule, in a PDF disclosure note and in a supporting invoice gets mapped together. This is critical for tie-out work, where supporting documents almost always arrive in different formats than the financial statements themselves.
Can ai/numbers handle prior year disclosure comparison?
Yes. ai/numbers automatically compares current-year figures and disclosures against the prior-year report, flagging changed values, unusual movements, missing updates and roll-forward issues. The system surfaces what’s changed so auditors can focus on whether the change is reasonable, properly disclosed and appropriately supported — instead of manually re-reading every page of last year’s financial statements to find the differences.
How does ai/numbers support financial statement tie out?
ai/numbers automates tick-and-tie by identifying figures across the financial statements, notes, tables and supporting documents, then checking that every figure is consistent across each location it appears. It flags any discrepancy — a number that doesn’t match between the income statement and the supporting note, a total that doesn’t add up, a prior-year figure that’s changed — for auditor review. What’s typically hours of manual cross-checking becomes minutes of exception review.
What is ai/numbers?
ai/numbers is dnl’s module for financial statement tie out, mathematical consistency validation and prior year disclosure comparison. It identifies figures across financial statements, notes, tables and supporting documents, maps them to their references, and flags any inconsistency for auditor review. ai/numbers handles internal consistency, external validation against supporting documents and prior-year comparison — automating the tick-and-tie work auditors typically do manually.
