About Canada Plumbing Invoicing
Canada Plumbing invoices must comply with local tax regulations. The applicable tax is GST/HST at 5%. Plumbing invoices must capture the full cost picture of a job: the call-out or mobilisation fee, time on site, parts and materials marked up appropriately, and any emergency or after-hours surcharges. Because materials costs vary widely — a simple washer versus a new boiler — itemising parts separately from labour protects you from disputes and gives clients the transparency they expect. Many plumbers also bill a fixed diagnostic fee before providing a repair quote, which should appear as a distinct line item.
Frequently Asked Questions
Should plumbers charge a call-out fee separately from labour?
Yes. A call-out fee covers travel, vehicle costs, and the time spent mobilising to site regardless of how long the job takes. Listing it separately from your hourly labour rate avoids confusion — clients understand they pay a fixed amount to have you arrive, then an hourly rate for the work itself.
How should plumbers invoice for materials and parts?
List parts and materials as a separate line item showing either the actual cost or a marked-up price (a 10–30% markup on trade prices is common and widely accepted). Keep receipts in case a client queries the cost. For large jobs, some plumbers split parts into a separate 'materials invoice' alongside the labour invoice.
What are standard payment terms for plumbing jobs?
Residential plumbing jobs are almost always due on completion — clients pay when the work is done and they're satisfied. For larger commercial projects or boiler installations, a 25–50% deposit upfront to cover materials is standard, with the balance on completion. Net 14 is reasonable for repeat trade customers.
Do plumbers need to charge VAT or GST?
In the UK, plumbers must register for VAT once turnover exceeds £90,000 and charge 20% on labour and most parts. In Australia, you need an ABN and must charge 10% GST once turnover exceeds $75,000 AUD. In the US, labour on plumbing services is generally not subject to sales tax, but parts may be taxable depending on the state.
How does GST/HST work on Canadian invoices?
Canada levies a 5% federal Goods and Services Tax (GST). In participating provinces, GST is combined with a provincial component into the Harmonized Sales Tax (HST) — for example, 13% in Ontario and 15% in Nova Scotia. In Quebec, GST and QST (9.975%) are charged separately. Businesses with annual revenue over $30,000 CAD must register, collect, and remit GST/HST.
Do I need a Business Number on my Canadian invoices?
If you are registered for GST/HST, you must display your 15-character Business Number (BN) on all invoices — this is your 9-digit BN followed by the program identifier (RT) and a 4-digit reference number (e.g., 123456789 RT0001). Invoices without a valid BN cannot be used by your clients to claim Input Tax Credits (ITCs).
Are there different invoicing rules by Canadian province?
Yes. Provinces that use HST (Ontario, New Brunswick, Nova Scotia, Newfoundland, PEI) require a single combined tax line. Quebec requires separate lines for GST and QST, and QST-registered businesses must also show their QST number. British Columbia, Saskatchewan, and Manitoba charge GST plus their own Provincial Sales Tax (PST), which may have separate registration and invoicing requirements.
