AttestWork vs Caseware Audit

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.

Caseware Audit is a web and Windows audit workflow covering planning through sign-off. It connects trial balance data with risks, procedures, evidence, notes, issues, and sign-offs in one live file, so team updates appear in real time. PEG-aligned planning uses guided prompts to tailor pre-built content and align objectives, risks, and procedures. Integrated journal-entry analytics identify anomalies and trends for focusing audit testing. AI assistance can summarize client support, extract details, and answer audit questions in context. From mapped accounts, the product can generate draft ASPE and ASNPO statements and export GIFI data to a tax-preparation tool. It supports engagements under International Standards on Auditing and Canadian Auditing Standards. Imports can come from Caseware Working Papers, desktop accounting software, engagement files, Excel or CSV, and structured accounting files. Caseware lists workpaper templates, evidence collection, review workflows, audit reporting, and a client portal. Cloud data uses AES-256 encryption at rest, TLS in transit, multifactor authentication, and role-based access controls. Pricing is available on request.
