5 Common Bookkeeping Mistakes Calgary Businesses Make (And How to Avoid Them)

Running a business in Calgary comes with its own set of challenges, and managing your books shouldn't be one of them. Yet many local businesses, from startups to established operations, make common bookkeeping mistakes that can cost time, money, and peace of mind. At Wattle Group Inc., we specialize in helping Calgary businesses stay organized and compliant—so here are five common mistakes we see, and how you can avoid them.

1. Mixing Personal and Business Finances

Many small business owners use the same bank account for both personal and business expenses. While it might seem convenient, this can lead to headaches when it’s time to reconcile accounts or file taxes.

Solution: Set up a separate business bank account and credit card. This keeps your records clean and makes it easier to track income and expenses related to your business.

2. Falling Behind on Data Entry

It’s easy to let receipts and invoices pile up, especially during busy periods. But falling behind on entering transactions means you lose real-time insight into your cash flow—and could miss critical deadlines.

Solution: Make bookkeeping a weekly routine or outsource it to a professional. At Wattle Group, we provide consistent, timely updates so you always know where your business stands.

3. Ignoring GST/HST Filings

Calgary businesses that are registered for GST/HST must file returns regularly. Missing these deadlines or filing incorrectly can lead to penalties and audits.

Solution: Stay on top of filing deadlines and know whether you should be filing monthly, quarterly, or annually. If you're unsure, we can help you determine your obligations and handle the filings on your behalf.

4. Not Reconciling Bank Accounts

Skipping bank reconciliations is a common mistake that leads to inaccuracies in your books. Unrecorded transactions, bank errors, or even fraud can go unnoticed if you’re not reconciling regularly.

Solution: Reconcile your bank and credit card statements at least monthly, if not weekly. This ensures your books reflect your actual financial position and helps catch issues early.

5. DIY Bookkeeping Without the Right Tools

Relying on spreadsheets or outdated methods can be risky. Without proper accounting software, it's easy to miss transactions, lose track of expenses, or make errors that snowball over time.

Solution: Use cloud-based accounting software like QuickBooks Online. As certified advisors, we can help set you up with the right system and keep everything running smoothly.
