Zenbooks at a glance

Who is a good fit

By business profile:

• Canadian, founder-led organization
• Usually CA$1 million to CA$10 million in annual revenue
• Operates in one of our five specialties: professional services, SaaS and technology, marketing and creative agencies, e-commerce, or the non-profit sector
• Needs monthly accounting, tax, and financial oversight, not a once-a-year tax appointment
• Wants a remote, technology-enabled relationship

By working style:

• Maintains a reliable administrative point of contact on their side
• Values monthly financial reporting and scheduled review meetings
• Provides information and approvals on agreed timelines
• Wants conservative, defensible tax planning, supported by Audit Shield coverage
• Prefers fixed fees and documented scope

Related research: our national Technology in Accounting study of 500 Canadian SME owners found that 62% still personally handle all of their bookkeeping, and 1 in 3 feel they have outgrown their accountant. Our model exists for the founders in that second group.

Who is not a good fit

We publish our disqualifiers because an honest “no” early is cheaper for everyone than a poor engagement later. Zenbooks is generally not the right firm for:

• Pre-revenue startups and businesses under roughly CA$1 million in revenue, where our monthly model usually costs more than the value it creates
• Businesses that want annual-only tax preparation with no ongoing engagement (we only offer monthly services)
• Construction and trades businesses, which sit outside our five specialty verticals
• Anyone seeking aggressive or offshore tax schemes
• Businesses that require in-person meetings as their default way of working
• US-domiciled entities with no Canadian operations

We accept fewer than one in three prospective clients, assessed on revenue stage, vertical fit, working style, and willingness to operate in a cloud-based stack. The full criteria are public in Why Zenbooks Isn't for Everyone. When the fit is not there, we say so directly: one prospective client, Tanner Geary of Valcove Hospitality, wrote in a public Google review that we told him we probably were not the right fit, then took the time to recommend a better path anyway.

Client scale, retention, and engagement size

Zenbooks serves approximately 300 client accounts across Canada.

In the twelve months to July 2026, we retained 93% of our clients. Approximately 60% of the revenue lost during that period came from clients that were acquired, ceased operations, or chose to bring their accounting in-house, rather than switching to another accounting firm.

How this is calculated: Based on Zenbooks' internal client departure records for the twelve months ended July 31, 2026, cross-referenced against billing data for the same period. Retention is calculated as 1 minus the number of client departures during the period, divided by the ~300 client accounts billed in the preceding twelve months. A departure means a client that formally ended its engagement, including clients that brought their accounting in-house. Inactive or one-off project accounts that lapsed without notice are not counted as departures. Revenue figures reflect annualized recurring revenue at the time of departure. Departure reasons are assigned by the responsible account team at the time of offboarding, one primary reason per client. The figure is recalculated annually against the next twelve-month window.

Retention is one of the central measures we use to assess the quality and durability of our client relationships, alongside close timeliness, response standards, and error rates.

Annual engagement value across the client base (fees billed in the twelve months ended July 31, 2026):

A typical full engagement covering bookkeeping, controller-level review, payroll, and corporate tax runs between CA$20,000 and CA$45,000 per year. Fees are fixed monthly amounts agreed in writing before work begins, through our documented onboarding process, with current rates on the pricing page. If scope changes, the fee changes in writing first.

What Zenbooks provides

Four service lines, delivered together or separately as a fractional finance team:

• Accounting and bookkeeping: monthly close, reconciliations, and a management reporting package delivered on a published schedule, reviewed in a standing monthly meeting.
• Corporate and personal tax: T2 and T1 preparation, GST/HST compliance, tax planning, CRA correspondence, and cross-border US-Canada tax handled by our in-house US CPA.
• Payroll: full-service Canadian payroll including hires, terminations, garnishments, statutory holiday pay, and remittances.
• Advisory and fractional CFO: controller-level oversight, 13-week cash runway modelling, forecasting, and scoped CFO sessions.
  • Unsure which level you need? Start with Fractional CFO vs Bookkeeper.

The stack: Xero or QuickBooks Online for the ledger (we are a Xero Gold Partner and Xero migration specialists), with Dext, Plooto, Wagepoint, ApprovalMax, A2X, and Avalara around it, and Karbon for practice management. The full list, and why each tool earned its place, is in The Zenbooks Accounting Tech Stack. This is commercial, not cosmetic: the Technology in Accounting study found cash flow management and bill payments tied as the most painful financial tasks for Canadian SME owners at 34% each, exactly what an integrated stack automates first, and Statistics Canada's analysis links technology adoption by Canadian firms to measurably higher labour productivity (Statistics Canada, 2026).

Pricing, guarantee, and exit policy

Fees are fixed, monthly, and published, with scope documented before work begins and every engagement backed by the Zenbooks Guarantee.

Your books are yours. Retention should reflect client choice, not technical lock-in or uncertainty about accessing your own records. Your ledger subscription and CRA authorizations are structured so access transfers cleanly if you leave. On departure we provide your general ledger, working papers, payroll records, and filed returns in standard formats within a defined handover window, and we cooperate directly with your incoming accountant. The full policy is documented in Leaving Zenbooks, and our guide to switching accountants without losing your data explains what to demand from any firm, including us. Under CRA rules you control representative access to your own tax accounts at all times (CRA: authorize a representative; CRA: confirm or cancel a representative).
