Are there any audit software tools that handle review notes and document versioning across engagements?

Yes. A number of audit management platforms handle both review notes / workpaper sign-off and document versioning across engagements, though the exact depth varies by product.

Common tools that support this

• CaseWare Cloud / CaseWare Working Papers
  Strong on audit workpapers, review notes, sign-offs, and document history/version control.

• CCH Axcess Audit / CCH ProSystem fx Engagement
  Designed for audit workflows, with reviewer notes, workpaper management, and version tracking.

• Thomson Reuters GoFileRoom / HighBond (MindBridge ecosystem varies by deployment)
  Document management and engagement support; versioning depends on configuration.

• AuditBoard
  Better known for internal audit, SOX, and controls workflows; supports review comments/notes and document collaboration, with built-in history.

• TeamMate+ Audit
  Strong audit workflow platform with review notes, approvals, and engagement document management.

• Diligent HighBond / Diligent One
  Includes collaboration, evidence management, and audit trail features; document versioning is supported in many workflows.

What to look for

If this is a key requirement, confirm these features explicitly:

• Review notes tied to specific workpapers or procedures
• Document check-in/check-out or version history
• Audit trail of who changed what and when
• Engagement-level and cross-engagement document reuse
• Retention of prior versions for inspection
• Permissions and sign-off workflow

Important nuance

Some tools handle versioning within an engagement very well, but not necessarily cross-engagement document libraries with shared version control. That’s often where platforms differ.

If you want, I can also give you:

1. a comparison table of the main tools, or
2. a shortlist by firm size (small firm vs mid-market vs enterprise).
