AI document extraction for auditors preparing audit evidence

Prepare invoice and statement rows for working papers while retaining a clear route back to the source evidence.

Try a document extraction

Audit preparation often starts with a folder of invoices, bank statements, and supporting documents. Dynamite Docs can extract draft document fields and table rows for a working-paper register. The reviewer compares the result with the original file before the data enters a test schedule.

Choose the fields for the procedure you intend to perform. An invoice register for vouching may need supplier, invoice number, date, currency, amount, and a reviewer-assigned evidence reference. A statement schedule may need account, period, and transaction detail. Keep the population definition, exclusions, and sampling decisions in the audit team’s own working papers.

Documents to prepare

Invoice evidence

Capture supplier, document number, document date, currency, line values, tax, and total. Retain credit notes as separate documents and preserve signs rather than merging them into invoice totals.

Statement schedules

Extract transaction rows and period balances. Check that the complete statement is present and that page order has not changed during scanning.

Supporting records

Prepare fields from purchase orders or expense evidence using the schema needed for the procedure. Add source locators yourself when assembling the reviewed register.

Review against the source

  • Compare identifiers, dates, and amounts with the source rather than relying on a confidence score.
  • Verify document count, page completeness, repeated documents, and omitted rows before treating the register as a population.
  • Keep extraction corrections separate from evidence observations and record the reviewer and review date in your working papers.
  • Retain the original evidence under your firm’s retention and access policies; an exported row is not the original document.

Prepare a reviewed handoff

  1. Define the preparation schema

    Select fields that support the planned procedure. Include currency and source identification, and document how unreadable or missing values will be treated.

  2. Review each extracted record

    Check the proposed values beside the source. Leave unresolved fields blank or flag them for follow-up rather than filling in an assumed value.

  3. Transfer checked rows to the working paper

    Export to Excel, CSV, or JSON. Verify counts and totals after import and attach the evidence references, reviewer notes, and procedure documentation required by your firm.

Use the accepted output

The output is a reviewed preparation table for an audit team’s existing working papers. Excel supports a register and exception sheets. JSON can carry fields and rows for an internal application with a defined schema.

Processing choices and allowances

Choose hosted AI, your own provider keys, or local Ollama on an eligible plan. Each successfully processed hosted page uses one PE. Free and Hobby BYOK use the same PE allowance; Pro and Ultra BYOK cost zero PE, with provider charges and limits still applying. Failed pages cost zero PE.

Check current plans, page limits, and capabilities and review storage and data-residency policies before processing sensitive records. Local model inference is a separate choice from browser-local file storage.

Workflow boundaries

  • Dynamite Docs does not select samples, determine evidence sufficiency, or issue audit conclusions.
  • Extraction cannot authenticate a document or prove that a recorded transaction occurred.

Questions about this workflow

Are exported rows audit evidence by themselves?

They are a preparation aid. Keep the original documents and the firm’s evidence references, and assess the information under your own audit methodology.

How should unreadable values be handled?

Record the exception and request a clearer source or other appropriate evidence. Do not infer a missing amount simply because it makes a total balance.
