GAASFlow

Purpose: GAASFlow is cloud audit engagement software for independent and growing CPA firms, with a shared engagement file for evidence, conclusions, review notes, and sign-offs.
Trial-balance workflow: Users can import trial balances by CSV or paste, map accounts to cycles, seed lead workpapers, and view prior-year variance and materiality assistance.
Workpapers and review: The product provides guided workpapers, evidence attachments, workpaper-linked review notes, electronic preparer and reviewer stamps, locks, and partner approval controls.
PBC portal: The client PBC portal provides expiring, token-scoped access to existing requests, while clients cannot access internal workpapers, risks, conclusions, or review notes.
Exports: GAASFlow can generate a governed report-package PDF and portable engagement ZIP with an integrity manifest; released engagements can also have a client-delivery DOCX.
Integrations: CSV and pasted trial balances are the supported self-service import path; QuickBooks Online and Xero API adapters require configuration, and customer-facing self-service authorization is not generally available.
Security: The stated controls include HTTPS/TLS, provider-managed database-volume encryption at rest, firm-level tenant isolation, role-based access, optional or firm-required TOTP MFA, and session revocation.
Compliance limits: GAASFlow says SOC 2, SAML/SSO, and an independent penetration-test summary are on its roadmap and are not currently claimed as completed or available.
Methodology: GAASFlow describes its methodology as an original, firm-adaptable toolkit and says it is not AICPA-endorsed or a substitute for professional standards or firm methodology.
Product limits: The product is an engagement file rather than a full general ledger; Excel workbook import and a complete statistical sampling package are not currently included.
Support: Starter includes standard product support, Professional adds priority support, and Firm includes a named support contact and security-questionnaire support.
Trial terms: The 7-day trial includes the working application, three user seats, and the completed Summit Ridge sample engagement, with no credit card required.
Price from: $349/mo
