Canada quote workflow
Quote to invoice without losing the tax model
The common breakdown is simple: the quote is built with one assumption, then the invoice is created later with missing province context. This page is the Canada workflow layer that ties quote subtotal, province selection, and final invoice tax display together.
This page does not try to replace tax advice. It exists to reduce workflow mistakes between quote and invoice.
Quote & Estimate Builder
Create the quote before final billing.
Quote to invoice guide
Long-form Canada workflow explainer.
Invoice Generator
Turn the approved quote into the final document.
Save the tax context early
The quote should preserve enough context that the invoice does not have to be rebuilt from memory later.
That means keeping the subtotal clear, knowing the province model, and deciding whether the final invoice will show one tax line or two.
- Quote subtotal first.
- Province model second.
- Invoice tax display third.
- Final PDF review last.
Quebec is the obvious high-friction case
Quebec quote-to-invoice workflows are exactly where a dedicated tax display model pays off. If the final invoice needs TPS and TVQ separately, capture that early instead of patching it later.
Current scope
This cluster is intentionally limited to Canada sales-tax and invoice workflows.
- Source of truth is the shared ca-tax-2026 dataset.
- These pages support quotes, invoices, province selection, and Quebec two-line tax display.
- Income tax, payroll, and province-specific filing edge cases are outside this sales-tax cluster's scope.
Canadian sales tax: common questions
GST, HST, PST, QST — what is the difference?
GST is the 5% federal Goods and Services Tax charged everywhere. HST is a single harmonized tax that combines the federal and provincial portions in provinces like Ontario and the Atlantic provinces. PST is a separate provincial sales tax added on top of GST in provinces such as British Columbia, Saskatchewan, and Manitoba. QST is Quebec's own provincial tax (TVQ), administered by Revenu Québec alongside the federal GST (TPS).
When do I have to register to collect sales tax?
Most businesses must register for GST/HST once taxable revenue passes the CAD 30,000 small-supplier threshold over four consecutive quarters. Provinces with a separate PST, and Quebec with the QST, have their own registration rules, so check both the federal and provincial requirements.
How should tax appear on a Canadian invoice?
Show the pre-tax subtotal first, then the tax as a clearly labelled line or lines, then the final amount due. In provinces with two taxes — and especially in Quebec — keep GST/TPS and PST/TVQ on separate rows so the client and the accounting trail can see exactly what was charged.
Do these tools give tax advice?
No. They apply the verified 2026 dataset rates to help you plan quotes and invoices. Unusual supplies, exemptions, and filing edge cases still need review against the Canada Revenue Agency or Revenu Québec, or with an accountant.
Freeze the assumptions when the customer approves
Store the customer's location, place-of-supply conclusion, registration numbers, tax status, currency, validity date, and whether prices are tax-exclusive. When the quote becomes an invoice, compare these fields before copying line items. If the supply location or scope changed, recalculate and document the revision instead of silently retaining the old rate.
