AttestWork
What AttestWork is
AttestWork is a workspace for audit, review, compilation, preparation, agreed-upon procedures, and examination engagements. It brings those workflows together with workpaper templates, evidence collection, review workflows, audit reporting, and a client portal. Teams can import trial balances and general ledgers, compare accounts, and surface exceptions. Document processing extracts text and structured fields from scanned PDFs, images, and ledger exports, while indexed engagement files can be searched by staff and connected AI agents. Its assistant can use engagement context and indexed files to draft procedure documentation and workpaper tables. Firms can connect Google Antigravity, Claude, ChatGPT, Gemini Spark, or another MCP client through OAuth-secured access. The product tracks client requests and links responses to related procedures. Preparers and reviewers must sign off, and editing work resets the affected sign-off tier. WorkpaperOS says it does not train its own models on customer work. The five-day trial is $0; paid plans are listed from $115/mo after the introductory period.
