Common Pitfalls That Can Cost You Money

October 2, 2025

Even with the best intentions, many small business owners fall into habits that quietly chip away at their profits. The truth is, bookkeeping mistakes don’t usually show up overnight — they compound over months or years, and by the time you notice, the fix can be expensive. Let’s look at some of the most common pitfalls and how to avoid them.

1. Mixing Business and Personal Spending

It might feel convenient to grab groceries with your business card or pay for fuel with your personal card “just this once.” But every time you mix accounts, your records get fuzzier. Come tax season, it’s harder to prove what was legitimate business spending — and you could lose valuable write-offs.

Tip: Use one card and one bank account strictly for business. It keeps things clean and defensible.

2. Forgetting About GST/HST

A surprising number of owners forget to set aside the sales tax they’re collecting. It feels like cash flow until the CRA asks for their share. Suddenly, that “extra” money is gone, and you’re scrambling.

Tip: Treat GST/HST like it isn’t yours. Move it into a separate account as soon as it’s collected.

3. Skipping Reconciliation

If you’re only recording expenses without reconciling to your bank and credit card statements, you’re running blind. Small errors pile up, duplicates slip through, and fraud could go unnoticed.

Tip: Reconcile monthly. It’s the single most powerful habit for clean books.

4. Ignoring Receipts

Digital banking makes it easy to think “the transaction is the receipt.” Unfortunately, the CRA doesn’t see it that way. Without the actual receipt or invoice, you could lose the deduction in an audit.

Tip: Snap a photo of every receipt. Cloud storage apps make it simple and automatic.

5. DIYing for Too Long

In the beginning, doing your own books is practical. But as your business grows, complexity grows too. Payroll, multiple accounts, year-end adjustments — these aren’t areas to learn by trial and error.

Tip: Bring in a professional before mistakes become costly. It’s usually cheaper than fixing years of errors.
