CPA Hub works alongside your tax software

CPA Hub is practice management, not tax-preparation software. You keep preparing and e-filing returns in Drake, Lacerte, UltraTax CS or TaxAct. CPA Hub runs the work around the return: collecting documents, engagement letters and e-signature, billing, your written security plan (WISP), and your clients' permission to share their tax information.

1. CPA Hub — best for compliance + AI extraction

CPA Hub is built around two things small firms struggle with most: staying WISP-compliant and eliminating manual data entry. It generates a firm-specific Written Information Security Plan (IRS Pub 4557 / FTC Safeguards Rule) and maintains it, and it automatically extracts data from 26 IRS forms. Rounded out with client portals, secure messaging, document management, e-signatures, and Stripe billing, it aims to be the whole hub for a solo/small practice. A 14-day trial includes a live, hands-on demo. Best for: firms that want compliance and intake automation native, not bolted on.

2. TaxDome — best all-in-one

The most established platform, top-rated and trusted by 10,000+ firms, with deep, proven tooling across CRM, portals, documents, workflow, billing, and e-sign. If you want breadth and a large community, it's the safe default. Best for: firms that want the broadest mature all-in-one and will handle WISP compliance separately.

3. Canopy — best AI tax workflow (premium)

Canopy is purpose-built with a polished end-to-end AI pipeline (Smart Intake → Smart Prep → Smart Delivery). It's highly rated. Standard is $74 per user per month billed annually, rising to $109 and $149 on higher tiers, with modules priced separately — so cost scales with headcount. Best for: firms that want a mature AI workflow and have the budget.

4. Karbon — best for team collaboration

Karbon's strength is turning email into tasks and giving a team one source of truth. If your bottleneck is communication across staff, it shines. Best for: multi-person firms whose constraint is collaboration.

5. Financial Cents — best budget option

The most affordable on this list, focused on simple, effective workflow and task management for small firms. Best for: very small or new firms where price is the deciding factor.

What it costs a four-person firm

Most practice management software charges per person. CPA Hub charges by how many clients you have, with no limit on users. Here is a year of each platform for a four-person firm, billed annually, base subscription only, at each vendor's published price.

Software How it's priced Four people, one year
CPA Hub By client count, unlimited users $790 (up to 50 clients) · $1,590 (up to 150) · $3,290 (up to 250)
Financial Cents (Team) $49 per user, per month $2,352
Karbon (Team) $59 per user, per month $2,832
Canopy (Standard) $74 per user, per month; some modules extra $3,552
TaxDome (Pro) $1,000 per seat, per year $4,000

Hire a fifth person and every line but one goes up by a seat. CPA Hub's price includes the written security plan (WISP) and AI document reading. Add-ons and card fees are extra on every platform, including ours.
