AttestWork vs CORAA

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.

CORAA is an audit engine for Indian CA firms that automates ledger scrutiny, vouching, reconciliation, working papers, and audit workflows. Its internal-audit system organizes client delivery across scopes of work, data requests, risk and control matrices, cycle programmes, evidence, observations, management responses, action tracking, and recurring monitoring. The engine tests the full ledger and suggests classifications and findings; auditors can accept or override those suggestions and retain professional judgement and sign-off. CORAA supports working papers and reports including Form 3CD, CARO 2020, Schedule III, and an Independent Auditor’s Report under SA 700. Connections include a desktop connector for Tally Prime, OAuth for Zoho Books, and Excel uploads for SAP S/4HANA, NetSuite, Busy, and Marg; MS Dynamics and QuickBooks are listed as coming. The cloud service works in a browser on desktop, laptop, tablet, or mobile, and Android and iOS are also listed. The 10-entity pack costs ₹30,000, with unlimited users and all features included. A free trial is available; there is no free plan.
