AttestWork vs Engagement CS

AttestWork is a web workspace for audit, review, compilation, preparation, agreed-upon procedures, and examination engagements. It imports trial balances and general ledgers, compares account balances, and surfaces exceptions. Document processing extracts text and structured fields from scanned PDFs, images, and ledger exports. Teams can search indexed engagement files, including OCR-processed PDFs, and an assistant can draft procedure documentation and workpaper tables using engagement context and files. Firms can connect AI clients such as Claude, ChatGPT, Gemini Spark, or another MCP client through an OAuth-secured connection. The workspace tracks prepared-by-client requests and can link client responses to the relevant request and procedure. Preparers and reviewers must sign off, and editing resets the affected sign-off tier. WorkpaperOS says it does not train its own models on customer work; files are kept in private buckets with short-lived signed links. A five-day trial costs nothing, with no card required. Professional is $57.50 a month for three months, then 115 USD per month; Premium is $92.50 a month for three months, then 185 USD per month.

Engagement CS is financial audit management software that also supports compilations, reviews and tax engagements. Its paperless process tracks work from engagement creation through archiving, with workpaper diagnostics and audit checklists. Teams share access to their work in a central binder. Workpaper tools described in the web demo include importing balances, rolling workpapers forward, tracking and routing work, and recording sign-off. Engagement CS includes workpaper templates, review workflows and audit reporting. The product page says it integrates with Microsoft Office and PPC guidance; the web demo describes links to PPC's Checkpoint Tools and SMART Practice Aids. Thomson Reuters offers a cloud trial that runs on a remote server accessed over the internet, but it cannot save or restore databases from a local workstation or LAN drive, and trial data is erased between visits. Connecting to the cloud trial requires a browser add-in download to the local PC. A separate download trial requires an account login or contact form submission. The product is paid, with pricing on request, and is listed for web and Windows with hybrid deployment.
