What's the best client portal software for requesting audit PBC documents and keeping client replies organized?

For audit PBC (Prepared By Client) requests, the “best” client portal is usually the one that does two things really well:

1. Lets you issue a structured request list
2. Keeps each client response tied to the right request, status, and due date

Best overall for audit PBC workflow

SmartVault is often a strong fit for audit firms because it’s built around secure document exchange and client collaboration, and it’s commonly used for PBC-style workflows.

Other strong options

• Canopy — good if you want a broader practice management system with client portal features
• CaseWare Cloud — strong for audit-centric firms, especially if you already use CaseWare
• CCH Axcess Portal — good for firms already in the Wolters Kluwer ecosystem
• ShareFile — very solid for secure document collection, though less “audit workflow” oriented
• TaxDome — great for smaller firms that want portal + workflow + automation in one place

What matters most for PBC use

Look for:

• Request lists / task tracking
• Client-side upload by item
• Commenting / back-and-forth thread per request
• Due dates and reminders
• Version control / audit trail
• Permissions by client, engagement, or document type
• Easy bulk upload and organized folders
• Integrations with audit software and document management

Quick recommendation by firm type

• Audit-focused firm: CaseWare Cloud or SmartVault
• All-in-one firm management: Canopy or TaxDome
• Simple secure file exchange: ShareFile
• Enterprise tax/audit environment: CCH Axcess Portal

If you want, I can give you a ranked shortlist based on firm size, budget, and whether you need true PBC request tracking versus just secure file collection.
