All three handle the basics. The differences show up in pricing structure, who they're built for, and how much room they leave to grow.

QuickBooks Online, Wave, and Xero all cover the core job — invoicing, expense tracking, bank reconciliation, basic reporting — but they're built for different-sized businesses, and the differences matter more as you scale than they do on day one.

Wave: free, with real limits

Wave's core accounting and invoicing tools are free, which makes it a common starting point for very small or early-stage businesses. The tradeoff shows up in payroll and payment processing, which carry their own fees, and in a reporting and integration ecosystem that's noticeably thinner than the paid alternatives once a business needs more than the basics.

QuickBooks: the default for a reason

QuickBooks Online is the most widely used option among Canadian small businesses and accountants, which matters practically — if you ever hand books off to a bookkeeper or accountant, there's a good chance they already know it well. It scales across several pricing tiers as your needs grow, from basic invoicing up to inventory tracking and project profitability, but the cost climbs with each tier.

Xero: built with an eye on integrations

Xero covers similar core functionality to QuickBooks with a somewhat different interface and a strong reputation for third-party app integrations, which can matter if your business relies on specific inventory, e-commerce, or point-of-sale tools that connect more cleanly to Xero than to its competitors. It's less universally used among Canadian accountants than QuickBooks, which is worth checking before committing if you plan to work with a bookkeeper.

How to actually decide

For a very early-stage business watching every dollar, Wave is a reasonable starting point. For most established small businesses, the choice between QuickBooks and Xero often comes down to what your accountant already uses and whether a specific integration you rely on favours one over the other.
