What is a punchcard?
A new unit of audit work.
A punchcard is a structured piece of audit work — a request, a test, a review step — with everything it needs to be completed and traced back to evidence. Send one to a client. An agent completes it. You review it. Together, punchcards make up the complete work of the audit.
1. Send
A structured request with selections, support types, and fields to extract. Clients see exactly what's needed — and get instant feedback when something doesn't tie out.
- Invoice — Selection #042
- Bank statement — Selection #042
- AR aging — doesn’t tie to TB
- Shipping doc — Selection #042
2. Complete
An AI agent reads the evidence, extracts the fields, runs the comparisons, and prepares the workpaper with citations. Mechanical work runs at scale. Judgment stays with the auditor.
3. Review
Every cell carries a reasoning trace and clickable citation. Validate, override, comment, and sign off — then export standardized workpapers without leaving the spreadsheet.
Flagship capability
CoAudit: substantive testing in minutes.
CoAudit is the first punchcard most firms send. Plain English in, audit workpapers with citations out. Up to 10× efficiency on substantive testing — without giving up judgment, traceability, or review.
Reads the documents your auditors do
Contracts, invoices, bank statements, payroll, debt agreements, revenue documents, offering memos. Extracts the fields and runs the comparisons.
Cites back to source evidence
Every conclusion is inspectable. One click takes you to the exact page, the exact line, the exact paragraph the agent reasoned from.
Built for substantive testing — and SOX
Great at substantive testing, revenue and expense testing, search for unrecorded liabilities, and operating-effectiveness testing of SOX controls.

What auditors are saying about CoAudit
In her first day using CoAudit, a senior at Richey May completed revenue testing across 41 selections and 123 supporting documents in 30 minutes — work that would normally take days to do manually.
CoAudit gives our auditors back the hours that don't require professional judgment, so they can spend more time where the risk actually lives.
Steve Checketts
Partner, Richey May
For a new classification standard on insurance investment bonds, I had CoAudit scan 12,750 pages of offering memos across 15 selections and quote the sections supporting each classification, against a flowchart I wrote. That isn't a procedure we would have attempted manually.
CoAudit didn't just make the work faster — it let us do work we wouldn't have done at all.
