• friendly reminder
• overdue notice
• late fee disclosure
• next steps

Workflow that works in Canada

Stop the reminder sequence once reliable payment confirmation arrives. Then follow Paid Invoice vs Receipt in Canada: What to Send to issue a paid invoice or receipt without erasing the original amount, taxes, or payment history.

1. Confirm client legal name, billing email, and payment terms before starting

2. Send a clear quote or estimate with validity dates and scope limits

3. Collect a deposit on larger jobs when materials or scheduling require it

4. Invoice the day work is delivered or the milestone is complete

5. Include Interac e-transfer instructions on every PDF

6. Follow up politely before the due date, then use a structured reminder if needed

Tax and compliance reminders

• Charge GST/HST/QST/PST only when registered or required to register
• Show tax registration numbers on invoices that collect tax
• Keep sequential invoice numbers and copies of every PDF sent
• Late fees must be disclosed in your terms before applying them
