Bookkeeping + Insights

Growth

For owners ready to stop guessing where the profit is going. You get monthly management reports showing exactly how the business is performing, then sit down with us quarterly to walk through the numbers and key ratios together — plus an annual goal-setting session and authority for us to deal with the CRA on your behalf.

Every client gets the same standard of compliance. Accurate books, filings on time, and CRA compliance aren't premium features — they're the foundation of a healthy business. What changes between packages is the level of guidance and insight you get on top of that.

On CRA authority: every package includes the access we need to file and report on your behalf. Growth and Strategic add full representation, which means we can speak directly with the CRA for you.

Every package is a fixed monthly fee tailored to your business — no hourly surprises — and the fee is fully tax-deductible. We quote after a Diagnostic Review rather than before, so the figure reflects what's actually involved in your books.
