How I tested client portals for accountants
I spent a few months testing client portals used by accounting firms of all sizes, from solo practitioners to multi-partner offices. The goal was to see how each platform supports daily accounting work like client onboarding, document collection, billing, and collaboration.
Here’s what I evaluated:
- Setup and onboarding: How easy it was to create a client workspace, import contacts, and start sharing files without support.
- Client experience: Whether clients could review, sign, and pay without confusion or extra instructions.
- Workflow handling: How automation manages recurring jobs like bookkeeping, payroll, or tax prep.
- Team visibility: Whether managers could see what was in progress, overdue, or waiting on a client.
- Security and compliance: How tools protect financial data through encryption, permissions, and audit trails.
- Integrations and flexibility: How well each platform connects with QuickBooks, Xero, and other accounting software.
