How much does a bookkeeper cost in Ontario?

The direct answer

Bookkeepers in Ontario price their work three ways: hourly (billed for time spent), flat monthly (one predictable fee for a defined scope of work), or per-transaction (priced off your volume). Most small businesses land on flat monthly, because it's the only model that doesn't turn your bookkeeping bill into a second variable expense to track. AccruBooks publishes its rate rather than gating it behind a call: monthly bookkeeping starts at $200/month, with HST filings included in that fee — not billed separately.

That "from" matters, and the rest of this page explains exactly what moves the number up from there — because the honest answer to "how much does a bookkeeper cost" is never a single figure. It's a starting point plus a short list of things that predictably add to it.

What actually drives the price

A fair bookkeeping quote is built from a small number of concrete inputs, not a vibe. The ones that matter most:

• Transaction volume. More transactions means more categorization and reconciliation work every month — this is usually the single biggest driver.
• Number of accounts. Each bank account, credit card, and payment processor you connect is another feed to reconcile monthly.
• Payroll. Running payroll adds recurring work: calculating and remitting source deductions, and issuing T4s at year-end.
• HST filing frequency. A quarterly or annual filer is less recurring work than a monthly filer, purely by frequency of the filing itself.
• The state of your backlog. Current, reconciled books cost less to maintain than books that need untangling first — see the catch-up section below.

None of these are hidden. Ask any bookkeeper to walk you through how they'd price your specific business against this list — if they can't, that's worth noticing.

Hourly vs. flat monthly: the real tradeoff

The hourly-vs-flat question isn't really about which number is lower — a well-scoped flat rate and an honestly-tracked hourly rate should land in the same place over a year. The real difference is who absorbs the risk of a messy month. Hourly, you do. Flat monthly, your bookkeeper does, which is exactly why a monthly subscription is what most small businesses settle into once volume becomes routine.

What should be included at a fair price

Whatever pricing model you're quoted, these belong in the base fee, not stacked on as add-ons:

• Full transaction categorization and monthly bank/card reconciliation
• HST return preparation and filing
• Monthly financial statements you can actually read, not just a data export
• A person who answers questions about your own numbers

This is also where AccruBooks draws the line: monthly bookkeeping includes HST filings in the fee. Year-end and tax returns (T1/T2) and fractional CFO work are separate services — real add-ons for real additional scope, not the basics repackaged as premium.

Red flags of too-cheap bookkeeping

A price that looks too good relative to your transaction volume is usually a price that's cutting something you'll only notice later:

• No stated reconciliation cadence. "We'll get to it" is not monthly reconciliation.
• HST billed separately, or not mentioned at all. If it's not in the base fee, ask exactly what is.
• No named person to reach. A ticket queue is not the same as a bookkeeper who knows your file.
• Vague scope. A quote that isn't tied to your transaction count, account count, or payroll status wasn't actually built for your business.

None of this means cheap is automatically bad — it means a price should be explainable in terms of the inputs above. If it isn't, you're not getting a discount, you're getting an unknown.

Catching up if you're already behind

If your books have gaps — a few months, a year, longer — the honest way to price the fix is off the same monthly rate, not a mystery "project fee." AccruBooks bills backlog months at the regular monthly rate plus 40%, always quoted up front once we've seen the volume involved. If you continue on as a monthly client afterward, 20% of that premium is credited back — so staying on brings the effective cost of catching up down to roughly 12% more than a normal month, per backlog month. For more on getting from behind to current, see our guide on catch-up bookkeeping.

The backlog premium exists because catch-up work is genuinely different from routine months — more digging, more judgment calls on old transactions. Pricing it as a defined percentage of your normal rate, instead of an open-ended hourly project, is what keeps it predictable even when the starting mess isn't.

Where AccruBooks fits

Monthly bookkeeping starts at $200/month, HST filings included, for clients across Canada; U.S. clients get bookkeeping only, since year-end tax and fractional CFO work are Canada-specific. Rather than quoting a range and asking you to book a call to find out where you land in it, you can build your own estimate with the quote builder — it asks for the same inputs listed above and gives you a number, not a callback request.
