If you've searched for a client portal for your accounting firm, you've run into the same problem every firm runs into: there are a lot of tools, they all claim to solve "client communication," and the pricing pages tell you very little about which one actually fits a firm your size.
This is a working reference, not a ranked "best to worst" list — the right platform depends heavily on whether your firm's real bottleneck is document volume, client adoption, full practice management, or something narrower. Below are eight platforms accounting firms commonly evaluate for the client-facing layer of their practice, with current pricing (verified against vendor pricing pages and, where a vendor page couldn't be independently confirmed, cross-checked third-party trackers, noted where that applies) and a short, honest read on who each is actually built for.
Quick Comparison

Osuria
Osuria is a branded digital workspace built specifically for the client-facing layer of an accounting firm's operations — secure document collection, centralized client communication in place of scattered email threads, proactive scheduled updates, and task requests, all inside an environment that carries the firm's own brand rather than a third-party interface. It's designed to sit alongside your existing tax, billing, and practice-management software, not replace it.
Osuria doesn't publish self-serve pricing; firms get a number sized to their size and needs through a short walkthrough rather than a price list. That's a real trade-off worth weighing against the published-price tools below — some firms want budget certainty before ever talking to anyone, others would rather have the conversation and get a tailored answer. See the full Osuria vs Liscio, Osuria vs SmartVault, Osuria vs TaxDome, Osuria vs Canopy, Osuria vs Karbon, Osuria vs Financial Cents, and Osuria vs SuiteFiles comparisons for the detailed breakdowns.
Liscio
Liscio is a purpose-built client communication and collaboration platform for accounting and tax firms, centered on encrypted messaging, secure file sharing, e-signature, and two-way email integration. Liscio restructured its plans in 2026 into three published, per-user tiers: Intelligent Files at $19/user/month (document exchange and e-signature only), Liscio Platform at $49/user/month — its most popular tier, adding full messaging and workflow — and Tax Team at $99/user/month for deeper tax-specific features (all billed annually; a la carte add-ons like client organizers run $5 each). Liscio's mobile-first apps are a genuine strength for driving client adoption, though it's deliberately narrower in scope than a full practice suite.
SmartVault
SmartVault is a document management and client portal platform with unlimited cloud storage, a branded portal, and unlimited external clients built into its core offering. Its three tiers — Business Pro, Accounting Pro, and Accounting Unlimited — run roughly $55–$85/user/month billed annually (with 2–3 user minimums), adding accounting-specific integrations, bulk print organizers, and e-signature/ID verification as you move up tiers. It's a strong fit for firms whose real pain point is document volume and compliance depth rather than communication breadth — the platform's center of gravity is files, not the broader client relationship.
TaxDome
TaxDome is a full practice-management platform combining workflow automation, CRM, billing, and a client portal in one system. Pricing is structured around annual per-seat commitments rather than simple monthly rates: roughly $700–800/seat/year on a 1-year Essentials (solo-only) commitment, scaling to around $1,000–1,200/seat/year on Pro and Business tiers, with discounts for 2- and 3-year commitments. It's the right shortlist candidate for firms that want to consolidate practice management and the client portal into a single platform rather than running the portal alongside separate practice-management software.

Canopy
Canopy is a full practice suite — CRM, document management, workflow, billing, payments, and a client portal — sold across three main tiers: Standard at $74/user/month, Plus at $109/user/month, and Premium at $149/user/month (all billed annually), with an Enterprise tier priced on request. The tiers differ mainly in automation depth rather than feature access; specialist modules like tax workflow automation and tax resolution are billed separately on a consumption basis. Canopy suits firms that want one system covering practice management end-to-end, not just the client-facing layer.
Karbon
Karbon is built around team workflow and collaboration — task management, email-to-workflow triage, and firm-wide visibility into who's doing what — with a client portal as part of the package rather than the centerpiece. Pricing runs $59/user/month on the Team plan and $89/user/month on the Business plan (both billed annually), with custom Enterprise pricing above that; there's no free or solo tier, just a 14-day trial. Karbon is the strongest fit for firms whose primary pain is internal task and workflow visibility, with client communication as a secondary layer on top.
Financial Cents
Financial Cents is practice-management software aimed at smaller firms that want workflow, deadline tracking, and client communication without the complexity (or price) of an enterprise suite. It's priced at $19/user/month on the Solo plan, $49/user/month on Team, and $69/user/month on Scale (billed annually; the branded client portal is only available from the Scale tier up), with custom Enterprise pricing above that. It's a reasonable shortlist entry for very small or solo practices prioritizing affordability over depth, but firms should check specifically which tier actually includes the branded portal before comparing headline prices.
SuiteFiles
SuiteFiles is a document management platform for professional-services firms, with unlimited document signing, advanced PDF tools, and a personalized client portal available from its Super Suite tier up. Based on third-party pricing trackers (SuiteFiles' own pricing page could not be independently confirmed at the time of writing), Semi-Suite runs around $225–250/month flat for up to 10 users and Super Suite around $210–225/month flat for up to 5 users, with custom Enterprise pricing above that. The flat, banded pricing can work in a firm's favor at higher headcounts, but it's worth confirming current figures directly with SuiteFiles before budgeting against them.
How to Actually Choose
Start from your firm's real bottleneck, not the feature list. If it's document volume and compliance depth, SmartVault or SuiteFiles deserve a serious look. If it's full practice management — you want workflow, billing, and the portal in one system — TaxDome and Canopy are built for that, and Karbon if internal team workflow is the sharper pain point. If it's a small firm wanting lightweight, affordable practice management, Financial Cents is worth a look. And if your bottleneck is that clients simply won't use whatever portal you already have — because it doesn't feel like it belongs to your firm — that's the specific problem Liscio and Osuria are each built to solve, with the trade-off between Liscio's transparent published pricing and mobile-first messaging versus Osuria's single branded workspace and tailored, request-based pricing.
Whichever direction your firm leans, it's worth seeing the actual client experience before you commit a year of budget to it. Explore the Digital Workspace or start using Osuria to see what a branded, consolidated client workspace looks like against your firm's own client base.
