Comparison

In-house vs outsourced accounting for small business

Whether to hire an accounting person or engage a firm, compared on true cost, breadth of expertise, and what happens when the person handling your books is away.

Short answer

Outsource while the work is under roughly one full-time role: a firm costs less than a salaried hire once benefits, payroll taxes, software and management time are counted, and covers bookkeeping through to tax in one engagement. Hire in-house once transaction volume needs daily attention or the work requires constant business context.

Compare total cost, not salary against fee

The usual comparison puts a bookkeeper's salary next to a firm's annual fee, and the salary looks competitive. It is not the same number. An employee costs salary plus the employer's share of payroll taxes, paid time off, benefits, software licences, training, equipment, recruitment, and your own time managing them. A firm's fee covers all of it, including the CPA review the in-house role would still need at year-end.

The continuity problem is the one that bites

A single in-house bookkeeper is a single point of failure. When they are on vacation, remittances still have deadlines. When they resign, the knowledge leaves with them, and it usually leaves mid-cycle. Businesses discover this at the worst possible time — during a sales-tax audit, a financing round, or a year-end when nobody can explain the prior year's entries. A firm carries the same knowledge across a team.

When in-house genuinely wins

  • Transaction volume needs daily attention rather than weekly batches
  • The work requires constant judgment calls only someone inside the business can make
  • You need someone physically present for cash handling or inventory
  • You are large enough to hire more than one person, which restores segregation of duties

The hybrid most growing businesses land on

An in-house person handles day-to-day recording, invoicing and payments, and a CPA firm handles month-end review, sales tax, payroll compliance and year-end filings. That gets the responsiveness of an employee and the expertise range and review of a firm, and it fixes the segregation-of-duties problem — the person recording transactions is not the person reviewing them.

Which one fits you

Outsourced firm

Businesses under roughly one full-time role of work, seasonal businesses, and anyone who needs bookkeeping through to tax without managing staff.

FAQ

At what point should I hire in-house?

The signal is volume and immediacy rather than revenue. When transactions need same-day attention, when someone must be present daily for cash or inventory, or when the outsourced engagement is approaching the fully loaded cost of an employee, the case for hiring is real. Below that, outsourcing usually delivers more expertise per dollar.

Can I outsource bookkeeping but keep tax in-house?

It is possible but rarely the efficient split. Bookkeeping is the higher-volume, more routine work and outsources well; tax is where judgment and current knowledge matter most and is where an outside CPA adds the most. Most businesses that split the work do it the other way round — keep the daily recording close, send the tax and review out.

What happens to my records if I switch providers?

Your records are yours. Ask before engaging anyone whether the books will live in an account you own — most cloud accounting platforms let a client hold the subscription and grant the firm access, which means a change of provider is a permissions change rather than a migration. Avoid arrangements where the data sits in a system only the provider can access.

Still not sure which way to go?

The right answer depends on numbers that are specific to you. Talk it through with a Montréal CPA — in English or French.
