Solo CPAs and small accounting firms are managing dozens of clients, deadlines, and document requests across tax season and year-round. The right practice management platform turns that chaos into a repeatable, scalable system.
Client portal, e-signatures, workflow automation, billing, and CRM — all in one platform at a flat annual price
The most powerful workflow and team collaboration tool for accounting firms — ideal for firms with 3+ staff
Clean interface, strong client portal, and excellent tax resolution tools for solo practitioners
The average solo CPA manages 150–300 clients. During tax season, that means tracking hundreds of document requests, deadlines, e-signatures, and client questions simultaneously — often across email, text, phone calls, and paper. Without a system, things fall through the cracks. Clients get frustrated. Deadlines get missed.
Accounting practice management software centralizes everything: client documents live in one place, workflows tell you exactly where every engagement stands, and client portals eliminate the back-and-forth email chains that eat your day. The firms that adopt these tools typically reduce administrative time by 30–40% and can serve 20–30% more clients without adding staff.
Below are the platforms we'd recommend to a CPA opening a solo practice or a firm looking to systematize their operations.
TaxDome has become the dominant platform for solo CPAs and small accounting firms because of its pricing model: one flat annual fee covers unlimited clients, unlimited storage, and the full feature set. No per-user fees, no per-client fees. For a solo practitioner with 200 clients, TaxDome at ~$600/year is an extraordinary value compared to competitors charging $50–$100/user/month.
Karbon is the premium workflow and collaboration platform for accounting firms. Where TaxDome excels at client-facing features, Karbon excels at internal team operations — work management, task assignment, capacity planning, and email integration. If you have 3+ staff and are serious about systematizing your firm's operations, Karbon is the best tool available.
Accounting firms with 3+ staff who want to systematize operations, reduce missed deadlines, and have full visibility into every engagement. Not the right fit for solo practitioners.
Canopy is the most polished and user-friendly accounting practice management platform. If TaxDome's learning curve is a concern, Canopy is the easier on-ramp — most firms are fully operational within a week. It includes a client portal, document management, e-signatures, workflow, and billing. It also has the best tax resolution tools of any platform, making it a strong choice for firms that do IRS representation work.
