🔬 How this guide was researched

We compared these invoicing tools using each vendor's pricing pages, documentation and feature lists, plus verified reviews on G2, Capterra and Trustpilot.

Each vendor's Canada documentation, including GST/HST, was checked as well.

For most of these invoicing tools, I'm relying on research rather than years of personal use.

We checked pricing in May 2026; plans change, so double-check before buying.

08 Frequently asked questions

What is the best free invoicing software for small business?

Wave is the best free invoicing software — unlimited invoices, unlimited clients, automatic payment reminders, and recurring invoices all completely free. Zoho Invoice is a strong alternative, also free for up to 500 invoices per year with a client portal included. Both are better than manually creating invoices in Word or Excel.

What invoicing software is best for Canadian businesses?

FreshBooks is the best invoicing software for Canadian businesses — it's headquartered in Toronto, fully supports GST/HST/PST, accepts CAD payments via Stripe, and has a Canadian support team. Wave is also an excellent Canadian choice for businesses that want free invoicing. QuickBooks Canada is the best option if you need invoicing plus full accounting and payroll.

How do I get clients to pay invoices faster?

Four methods that work: (1) Include a "Pay Now" button directly in the invoice email — online payment reduces average payment time from 14 days to under 4 days, (2) Set up automatic payment reminders at 3 days before due, on the due date, and 7 days overdue, (3) Offer a small early-payment discount (e.g. 2% if paid within 5 days), (4) Require a deposit before starting work. FreshBooks, Wave, and QuickBooks all support automated reminders and online payment links.

What should a Canadian business invoice include?

A CRA-compliant Canadian invoice must include: your business name and address, your GST/HST registration number (if registered), the invoice date and number, a clear description of goods or services, the subtotal before tax, the GST/HST amount as a separate line, the total amount due, and acceptable payment methods. If invoicing in a province with PST, include PST separately. FreshBooks and QuickBooks handle all of this automatically.
