How to Invoice Clients Professionally in Canada (Step-by-Step)

Introduction

Sending a professional invoice is one of the easiest ways to get paid faster and build trust with your clients.

But many freelancers and small businesses in Canada are unsure what to include.

What Should Be Included in an Invoice?

A proper invoice should include:

• Your business name and contact information
• Your client’s name and details
• An invoice number
• Invoice date and due date
• Description of services or products
• Total amount owing
• Applicable taxes (GST/HST/PST/QST)

Use Clear Descriptions

Avoid vague descriptions like “Work completed”.

Instead, be specific:

• Website design (5 pages)
• Monthly bookkeeping services
• Consultation – 3 hours

Set Payment Terms

Always include clear payment terms such as:

• Due on receipt
• Net 7, Net 15, or Net 30

This helps avoid confusion and late payments.

Add Taxes Correctly

Depending on your province and registration status, you may need to charge:

• GST
• HST
• PST or QST

Make sure your invoice clearly shows tax breakdowns.

• Forgetting to include a due date
• Using inconsistent invoice numbers
