Good bookkeeping is the foundation everything else in your business sits on — from knowing if you’re actually profitable to being ready when tax season hits. Here are the mistakes we see most often, and how to avoid them.

1. Mixing personal and business expenses

Running personal purchases through a business account (or vice versa) makes your books harder to reconcile and can raise red flags in a CRA review. Keep separate accounts and cards from day one.

2. Falling behind on reconciliation

Waiting months to reconcile bank statements means small errors pile up and become much harder to trace. Monthly reconciliation catches problems while they’re still easy to fix.

3. Not tracking HST separately

HST collected isn’t your revenue — it belongs to the CRA. Businesses that don’t track it separately sometimes spend it as if it were income, then scramble to cover it at filing time.

4. Losing receipts

Without a receipt, an expense can be disallowed in a CRA review even if it was a legitimate business cost. A simple habit — photographing receipts as you go — prevents this entirely.

5. Waiting until tax time to look at the books

Bookkeeping should tell you how your business is doing right now, not just feed your accountant once a year. Reviewing your numbers monthly means you catch cash flow issues while there’s still time to act.

The fix for most of these is consistency, not complexity — a little attention every month beats a scramble every April. If your books have fallen behind or you’d rather hand this off entirely, we offer monthly bookkeeping starting from $300. Call +1-905-279-6367 to book a free consultation.
