Assurance
AttestWorkAudit, review, compilation, preparation, AUP, and examination engagements in one workspace.
The engagement file your AI can work in - and your CPA signs. Plan, import the trial balance, request PBC items, let the bots draft the workpapers, and clear review notes - built by auditors with decades of experience, including the Big 4, and part of the integrated WorkpaperOS platform.
No card required. Sign-up takes 60 seconds.
AI does the heavy lifting
Bots draft the workpapers. Your CPA signs.
AttestWork puts AI bots on the repetitive parts of an engagement - tying the trial balance to the general ledger, gathering evidence for each area, drafting procedure results the way the app is wired, and assembling the financial statements. Your firm's CPA reviews the drafts, revises where relevant, and signs off as preparer and reviewer. Nothing is 'done' until a person at your firm marks it prepared and reviewed - WorkpaperOS never puts anyone in your loop.
- Connect your AI over MCP
- Engagement setup + template agility
- PBC, Drive sync, and AI on watch
- Drafted workpapers + sign-off rails
A typical flow
Bots do the repetitive work; a person reviews and signs off wherever judgement matters.
One engagement, start to signed
Decades of audit experience, wired into the bots.
AttestWork was designed and configured by CPAs and Chartered Accountants who spent their careers in audit firms, including the Big 4. That experience is in the product: the templates, the procedures that cite the standards they satisfy, the risk defaults, and the guardrails that decide what a bot may never touch. The bots draft the way experienced auditors work - then your CPA reviews, revises where needed, and signs off as preparer and reviewer.
- 1Connect your AI in five minutesAdd the WorkpaperOS connector to Google Antigravity, Claude, or ChatGPT - one URL, OAuth sign-in, firm-scoped, revocable.
- 2Say “set up the audit”Upload the engagement letter and the bot scaffolds the complete file - 84 sections, standards-referenced procedures, add-ons attached. Or pick templates manually.
- 3Plug in Google Drive and seed PBCEvery request gets a synced Drive folder and an in-app folder. Clients deliver through the portal or the shared folder - same file room.
- 4Put your AI on watchSchedule your assistant to index new uploads, match them to PBC requests, and draft follow-ups for your approval.
- 5Import the numbersUp to ten years of trial balances (QBO exports import directly), automatic TB-to-GL tie-out, mapping, and AJEs that flow everywhere.
- 6Plan like a partnerComputed materiality, assertion-level risk with the AU-C 240 revenue presumption wired in - flowing straight into the sampling engine - and expectations-driven analytics.
- 7Bots draft real workpapersCash schedules with agreed-to-TB ticks, PP&E rollforwards rebuilt from your firm's own Excel templates, evidence linked to every procedure.
- 8Your CPA signs - and the rails holdBot edits reopen stale sign-offs, reviewed procedures refuse overwrites, and every AI action lands in the MCP log.
Every guardrail in that flow - the templates, the defaults, the refusals - is a decision made by auditors with decades inside firms including the Big 4. The bots carry the experience. Your firm carries the license. The file shows both.
