What to ask vendors before buying

1. How do you handle role-based reviewer permissions at engagement, folder, and document level?
2. What are the max file sizes and performance limits?
3. Do you support check-in/check-out, version control, and audit trails?
4. Can reviewers approve/comment without seeing restricted sections?
5. How are sign-offs captured and retained?
6. Can permissions be synchronized with Azure AD / SSO?
7. What’s the experience for large PDF/Excel workpapers?
8. Do you support templates, rolling forward engagements, and task dependencies?
