Bookkeeper vs. CPA: When Do You Need Each?

“Do I need a bookkeeper or an accountant?” is one of the most common questions Ontario business owners ask. The short answer: they do different things, and many businesses eventually need both.

What a Bookkeeper Does

A bookkeeper handles the day-to-day financial record-keeping for your business. They keep your books accurate and up to date so you (and your accountant) can make informed decisions.

  • Recording income and expenses
  • Bank and credit card reconciliation
  • Managing accounts payable and receivable
  • HST/GST filing and payroll processing
  • Producing monthly financial statements
Typical cost: $300–$800/month for a small business in Ontario. See our full pricing guide →

What a CPA Does

A Chartered Professional Accountant (CPA) is a licensed professional who can provide higher-level financial services. In Ontario, only CPAs can perform audits and issue certain financial opinions.

  • Year-end financial statements and corporate tax returns (T2)
  • Tax planning and strategy to minimize your tax bill
  • Business advisory — incorporation, restructuring, succession
  • Audits, reviews, and compilation engagements
  • CRA representation if you’re audited
Typical cost: $1,500–$5,000+ per year for small-business accounting and tax filing.

Do You Need Both?

Many Ontario businesses use both: a bookkeeper manages the ongoing data entry and reconciliation, while a CPA handles year-end financial statements, tax filing, and strategic planning. This combination often saves money because your CPA spends less time organizing messy records and more time on high-value advisory work.

If you’re a sole proprietor with simple finances, one professional may be enough. As your revenue grows past $100K or you incorporate, having both becomes increasingly valuable.
