Outsourcing bookkeeping vs. hiring in-house: how to actually think about it

The short answer

Outsourced bookkeeping is one flat monthly fee that covers the work, the software, and the expertise. An in-house hire is a base salary plus everything that comes attached to employing someone: employer payroll costs, software licences, training time, vacation coverage, and the risk of the whole thing stopping when one person is out. Neither option is automatically cheaper — it depends on how much bookkeeping work your business actually generates, and that's a volume question, not a price question.

What an in-house hire actually costs to run

A salary is the number people compare, but it's not the number that determines whether hiring makes sense. Once someone is on payroll, a business is also carrying:

• Employer payroll costs — CPP and EI contributions the employer pays on top of wages, not deducted from them. These are real, ongoing costs tied to every dollar of payroll, and the math is specific enough to your numbers that we built a free employer cost calculator rather than quote a generic figure here.
• Software and systems — a bookkeeping seat, whatever else the role touches, and someone administering access.
• Training and ramp-up time — a new hire doesn't arrive knowing your chart of accounts, your vendors, or how your business actually works. That time is a cost even when it doesn't show up on an invoice.
• Management time — someone has to hire, onboard, review the work, and manage the person doing it. That's a cost too, even when it's the owner's own time.
• Vacation and coverage — one person means one point of failure. When they're out, the books either wait or someone else has to pick up unfamiliar work.
• Key-person risk — if that one person leaves, the process, the shortcuts, and the institutional knowledge about your books usually leave with them.

None of this means hiring is a bad idea — it means the salary is the floor of the cost, not the whole cost. Any comparison that stops at "salary vs. our monthly fee" is comparing the wrong two numbers.

What outsourcing actually gets you

An outsourced arrangement collapses most of that list into one line item. There's no separate payroll cost because there's no payroll — you're a client, not an employer. There's no software licence to manage on your end. There's no single point of failure, because a firm with more than one person on staff doesn't stop functioning when one person takes a week off. And you're generally getting senior eyes on the file — someone who's set up books for other businesses before, not learning your chart of accounts from scratch.

Ours, for reference, starts at $200/month, with HST filings included — one number, no separate line items for software or coverage.

What you give up is on-site presence. Nobody's sitting at a desk in your office, available to be waved over. For most small businesses that's a non-issue — bookkeeping doesn't require physical presence, it requires access to your accounts and a clear line of communication. But it's a real trade-off worth naming, not pretending away.

The other thing worth asking, before signing with any outsourced provider: who actually does the work? A named person you can reach, or whoever's available that week? That question matters more than the price on the page — see our full guide on how to choose a bookkeeper for what else to check.

The honest break-even

There's no universal dollar figure here, and anyone who gives you one is guessing. The qualitative version is more useful: in-house hiring starts to make structural sense when bookkeeping has become a full-time job in its own right — daily transaction volume, payroll runs for a growing headcount, reporting cadence that genuinely needs someone dedicated to it every day. Below that point, you're paying for a full-time seat to do a part-time amount of work, plus all the overhead listed above.

Most small and growing businesses in Ontario sit below that line for longer than they expect. The books grow slower than the business feels like it's growing, and by the time volume genuinely justifies a dedicated in-house hire, many owners have already been paying outsourced rates for years — rates that scale with the work, not with headcount overhead.

A middle path exists too

This isn't strictly binary. Some businesses run outsourced bookkeeping day-to-day and add a fractional layer for higher-level financial work as they scale — forecasting, cash-flow planning, board-ready reporting — without ever carrying a full in-house finance team. If that's the direction you're headed, our guide on fractional CFO support covers what that layer looks like and when it's worth adding.

How to decide for your business

Start with the volume question, honestly: is bookkeeping currently a few hours a week, or is it already eating a full workday? Run the real numbers on what an in-house hire would cost using the employer cost calculator — salary is only the starting point. Then compare that fully-loaded number, not the salary alone, against what an outsourced flat fee would run. For most businesses below full-time volume, the flat fee wins on cost and on resilience. Above that volume, run the comparison again — the answer can flip, and that's fine. The point isn't to pick a side; it's to compare the right two numbers.
