Frequently asked questions
What are the key differences between TaxDome and Onvio?
TaxDome is an all-in-one platform that combines workflow automation, client communication, CRM, e-signatures, billing, a branded client portal, mobile apps, and team collaboration tools in a single subscription.
Onvio offers core practice management tools, such as document management, time and billing, client portal, and project tracking, but lacks advanced communication tools, AI capabilities, deep integrations, and cohesive automation.
How does the pricing structure compare between TaxDome and Onvio?
TaxDome offers transparent pricing based on active clients, not seats: $1,500 a year covers 150 active clients, with additional clients starting at $15 each and lower rates as your volume grows. The plan includes 20 seats and all core features.
Onvio’s pricing is modular: Essentials and Advanced packages cost $2,275 CAD/year and $4,075 CAD/year, respectively, with additional user fees ($135 CAD to $200 CAD per user annually), which puts 20 seats at $4,840 CAD on Essentials and $7,875 CAD on Advanced. Add-ons are required for critical tools.
Do TaxDome or Onvio offer tools specific for bookkeepers?
Yes, TaxDome provides a Bookkeeping Hub with real-time general ledger access and seamless integration with clients’ books, included in the plan at no separate charge. Other platforms typically price this kind of offering separately.
Onvio offers time and billing and project tracking features, but lacks specialized bookkeeping features like GL workflows or automation for bookkeeping tasks.
Is Onvio a legacy solution?
Onvio is a widely used cloud platform with roots in traditional practice management, and some firms describe it as more legacy-style. Its modular packages with add-ons for critical tools, limited mobile support (no client mobile app), and lighter communication, AI, and integration options are the main reasons firms look for a more modern platform.
If you want a single vendor to handle client communication, automation, bookkeeping features, and more natively, TaxDome is designed for that use case.
Do TaxDome or Onvio offer tools specifically for tax preparers?
TaxDome supports an end-to-end tax workflow: intake via organizers, automated document requests, KBA-capable e-signatures, and integrations with tax programs.
Onvio supports source document collection and invoicing via their portal but lacks essential tax workflow features.
How do e-signature capabilities compare between TaxDome and Onvio?
TaxDome offers KBA-compliant e-signatures, meeting IRS requirements for forms like 8879, and supports advanced and qualified electronic signatures (AdES and QES), which meet EU and international standards for global compliance
Onvio provides basic e-signature capabilities via integrations.
What automation and AI features does each platform offer?
TaxDome provides workflow automation, conditional triggers, and AI-powered reporting with dashboards and natural-language search.
Onvio lacks AI automation and advanced triggers.
Which platform provides stronger data protection and compliance features?
TaxDome is SOC 2 Type II certified, offers firm-wide activity feeds, security audit trails, and enforced 2FA policies, ensuring enterprise-grade compliance.
Onvio delivers robust security and encrypted storage, though it does not promote firm-level audit controls or 2FA enforcement in the same way.
Can I bring my firm from Onvio to TaxDome?
Of course! If you have an existing account with Onvio, we have multiple import tools that allow you to bring your firm over to TaxDome quickly and easily. To support your transition, we offer a discount of up to 6 months’ worth of TaxDome free.
