Ignition + Karbon: The Complete Practice Management Stack
Most growing Canadian accounting firms use both tools together. Each handles a different part of the client lifecycle.
Ignition
Proposals, Engagement Letters, and Billing
~$135 CAD/mo
- Proposals with embedded pricing and e-sign
- Automated engagement letter generation
- Recurring billing with auto-collect
- Deep Xero and QBO invoice sync
Karbon

~$80 CAD/user/mo
- Workflow templates for recurring tax and bookkeeping work
- Email triage linking messages to client work items

Ignition automates getting paid — proposals, engagement letters, and billing. Karbon automates getting work done — workflows, email, and client communication. Together they cover the entire client lifecycle from first proposal to final deliverable.

Karbon
Top PickThe core practice management platform — workflow automation, email triage, client portal, engagement letters, and billing
From ~$80 CAD/user/mo
Team plan ($59 USD/user) — per-user pricing
Karbon is used by Canadian accounting firms of all sizes as the central hub for client management. It now covers the full client lifecycle: workflow templates (tax returns, monthly bookkeeping, year-end), email triage, a client portal (Karbon for Clients), engagement letters (Karbon Engagements), and invoicing with payment collection. It integrates with Xero Practice Manager and supports Canadian tax workflow templates. Many firms pair Karbon with Ignition — using Ignition for streamlined proposal-to-payment automation and Karbon for everything else.
Strengths
- Comprehensive workflow templates for recurring work like monthly bookkeeping, T2 prep, and HST filing — the best in the category
- Email triage system that links incoming client emails directly to relevant work items, reducing inbox chaos
- Client portal (Karbon for Clients) where clients can upload documents, complete tasks, view invoices, and communicate securely
- Engagement letters and proposals (Karbon Engagements) with built-in e-signatures, connected directly to workflows and billing
Watch For
- Per-user pricing adds up quickly for larger firms — a 10-person firm pays ~$800+ CAD/month
- Engagement letters feature (Karbon Engagements) is newer and less mature than Ignition for high-volume proposal workflows
- Steep onboarding process with a significant time investment to set up workflow templates properly
CPA Verdict
Karbon is the most comprehensive practice management platform for accounting firms, now covering workflow, client portal, engagement letters, and billing. For firms that want one platform for client management, Karbon alone may be sufficient. However, many firms still pair Karbon with Ignition — using Ignition for its more polished proposal-to-payment automation (especially for high-volume client onboarding) and Karbon for workflow, email triage, and the client portal. This combination covers the full client lifecycle.
Ignition
The engagement and billing add-on — proposals, engagement letters, and automated payment collection
From ~$135 CAD/mo
Core plan ($99 USD) includes proposals, e-sign, and billing
Ignition integrates directly with Xero, QuickBooks Online, and Xero Practice Manager, making it a natural fit for Canadian cloud accounting firms. Proposals can include multi-currency pricing (CAD/USD), and engagement letter templates can be customised for Canadian regulatory requirements. The platform handles recurring billing with automatic payment collection, which eliminates the accounts receivable problem that plagues most Canadian accounting firms.
Strengths
- Proposals with embedded pricing options that clients can accept and e-sign in minutes, eliminating back-and-forth emails
- Automated engagement letter generation tied to the accepted proposal, ensuring compliance without manual document creation
- Recurring billing with automatic payment collection (credit card or direct debit), reducing accounts receivable to near zero
- Deep Xero and QBO integration — accepted proposals automatically create invoices in your accounting software
Watch For
- Starting at ~$135 CAD/month ($99 USD), it is a significant cost for solo practitioners or very small firms with limited client volume
- The proposal builder has a learning curve, and importing existing templates takes time during initial setup
- Not a practice management tool on its own — it handles proposals and billing but not workflow, email triage, or client communication
CPA Verdict
Ignition is the platform we recommend for the proposal-to-payment problem specifically. If your firm spends hours creating engagement letters, chasing signatures, and following up on invoices, Ignition eliminates all of that. It pairs with Karbon as the complete practice management stack — Ignition for getting paid, Karbon for getting work done.
TaxDome
Smaller firms wanting an all-in-one platform for client management, workflow, invoicing, and a client portal
From ~$90 CAD/mo
Per-firm pricing ($66 USD) — unlimited users on higher plans
TaxDome is an all-in-one practice management platform that combines client portal, workflow management, invoicing, proposals, and document management in a single system. For Canadian firms, it supports e-signatures on engagement letters, recurring invoicing in CAD, and basic workflow templates for Canadian tax deadlines. The unlimited-user pricing on higher tiers makes it cost-effective for growing firms.
Strengths
- All-in-one platform covering client portal, workflow, invoicing, proposals, and document management — fewer tools to manage
- Unlimited users on higher plans, making it cost-effective for firms adding staff without increasing per-seat costs
- Client portal with secure document sharing, e-signatures, and messaging — clients have one place to interact with your firm
Watch For
- The workflow module is less sophisticated than Karbon for complex recurring work like multi-step tax preparation
- Proposal and billing features are less polished than Ignition — functional but not as streamlined
- The interface tries to do everything, which can feel overwhelming and less focused than specialised tools
CPA Verdict
TaxDome is a solid choice for smaller Canadian accounting firms (1-10 staff) that want one platform for everything rather than managing multiple subscriptions. It handles the basics of proposals, workflow, invoicing, and client communication well. However, firms with complex workflows or high proposal volume will find Karbon (for workflow) and Ignition (for proposals/billing) to be stronger in their respective areas.
How We Tested
Seb Prost, CPA
10+ years CRA experience
We evaluated each platform from the perspective of a Canadian CPA running a cloud accounting firm. We tested proposal creation speed, engagement letter automation, Xero and QBO integration depth, workflow template flexibility, and billing collection rates. We also assessed Canadian tax workflow support and pricing in the context of typical Canadian firm sizes. Platform pricing was verified in March 2026.
The Bottom Line
For Canadian accounting firms, the ideal setup is Ignition plus Karbon together. Ignition handles the proposal-to-payment cycle with the most streamlined automation in the category, while Karbon manages everything else — workflow, email triage, client portal, and team coordination. Karbon now also offers its own engagement letters and billing, so it can work as a standalone platform for firms that want fewer tools. TaxDome offers the best all-in-one value for smaller firms that want simplicity over specialisation.
