What is audit software?

Audit software is the set of tools an audit firm uses to plan, perform, document and review an audit: engagement and workpaper management, client requests and evidence collection, data extraction and analytics, confirmations, and increasingly AI that drafts testing and reads documents. It is separate from the client's accounting system, which it examines.
