Plumber Invoice Template - Canada

The tax requirement depends on your province. Five provinces (BC, AB, SK, MB, QC) use GST only, while the remaining provinces apply Harmonized Sales Tax (HST), which combines federal and provincial tax into a single rate. Your invoice template should reflect your specific province's requirement—most templates let you customize the tax label and rate accordingly. Check the CRA website for your province's current rate, as these can change periodically. Ensure your invoicing software automatically reflects rate updates to stay compliant with tax obligations.

Most Canadian plumbers charge an emergency or after-hours surcharge—typically 50–100% above the regular service call fee—for work between 5 PM and 8 AM or on weekends and holidays. Your invoice should clearly separate the base service call fee from the emergency surcharge with detailed descriptions, helping customers understand the premium. Document the exact time of the call for reference. This transparency reduces billing disputes. While provincial regulations don't restrict emergency pricing, your invoice must make the charge obvious and justifiable to the customer.

Create distinct line items for parts and labor, showing quantity, description, unit price, and total for each. For example: "Bathroom faucet cartridge (qty 2 × $40 = $80)" as one line, and "Labor: faucet installation (1 hour × $85/hr = $85)" as another. This breakdown builds customer trust and simplifies your accounting. When replacing fixtures, itemize the fixture cost separately from installation labor. Accurate quantities and prices eliminate disputes and make invoices professional and defensible.

Yes—most Canadian plumbers charge a service call fee ($75–$150) to cover diagnosis, travel, and equipment setup. List this as a distinct line item labeled "Service call and diagnostic fee" or "Visit charge." If the customer proceeds with repairs, you can waive or credit this fee against the final bill—note this clearly to show customer value. If no repair is authorized, the service call fee still applies. A clear, documented policy prevents misunderstandings and ensures you're paid for time spent on diagnosis.

Add a warranty section to your invoice footer or as a separate note specifying coverage and duration. For example: "All parts installed carry a 12-month manufacturer's warranty. Labor is guaranteed for 90 days from completion." Clarify what qualifies as a warranty claim versus customer misuse, and include your contact information for warranty requests. This protects both parties by setting clear expectations. Keep invoice copies with warranty details for future warranty claim support. For high-end fixtures with extended warranties, link the invoice to manufacturer documentation.

Yes, commercial invoices typically require additional fields: project codes, department billing codes, and purchase order numbers. Commercial clients often need invoices referencing specific projects or purchase orders for their payment processing, so confirm these details upfront. Commercial rates may also differ from residential rates, requiring separate line items. Some commercial clients have specific invoice formatting requirements or payment terms, so discuss these before work begins. Including flexibility for these details prevents billing delays and ensures faster payment cycles.

The diagnostic fee is still due regardless of whether the customer proceeds with repairs. Your invoice should clearly state this upfront as a line item: "Diagnostic fee (non-refundable)" or "Service call charge applies regardless of repair authorization." This protects your business from unpaid diagnosis visits. You can incentivize repair decisions by crediting the diagnostic fee (50–100%) toward repair costs if the customer moves forward. Document your diagnostic fee policy on your invoice template and communicate it verbally during initial contact to prevent disputes.

Yes, many Canadian plumbers charge a travel fee or mileage rate, especially for calls outside their primary service area. You might invoice a flat "travel surcharge" for distant calls, charge per kilometer, or include mileage in a tiered service fee. Clearly label this on your invoice—"Travel surcharge," "Mileage fee ($X/km)," or "Out-of-area service charge"—so customers understand the additional cost. Document the distance or include it in notes for transparency. Communicate your travel fee policy upfront to prevent customer surprise and disputes.
