Punchcard is the assurance system of action for modern audit teams, risk consultants, and their clients. Built by Substantive AI, Inc., Punchcard helps audit professionals move from scattered requests, messy evidence collection, and manual testing into one structured AI-powered workspace for audit work.

Auditing depends on trust, judgment, and traceable evidence, but too much of the work still lives across spreadsheets, email threads, file folders, PDFs, and disconnected workpapers. Punchcard brings that work together. Its platform helps teams manage PBC request lists, collect client support, organize audit evidence, run substantive testing, prepare reviewable workpapers, and review financial statements with clear citations back to source documents.

Punchcard is designed for the way auditors actually work. Clients get clear request flows that explain what is needed and keep every upload tied to the right item. Auditors get AI agents that can read contracts, invoices, bank statements, payroll files, debt agreements, revenue documents, and other audit evidence; compare support against assertions and risks; flag issues; and produce workpapers that remain inspectable, editable, and ready for human review.

The company’s flagship capability, Punchcard CoAudit, lets audit teams ask questions in plain English, analyze evidence, trace conclusions to exact pages or rows, and take the next action without leaving the audit workflow. Punchcard supports external audit, internal audit, SOX controls testing, substantive testing, financial statement review, evidence collection, and audit workpaper automation while keeping professional judgment in human hands.

Punchcard exists to make audits feel simple again: clearer for clients, faster for teams, more traceable for reviewers, and higher quality for the firms responsible for assurance.
