What the generator does for you
- Automatic tax calculation based on the billing province: GST + QST in Quebec, HST in Ontario or the Maritimes, GST + PST out West — official rates applied automatically (custom taxes possible when needed).
- Live preview: you see the exact invoice while you fill it in.
- Discounts and deposits: percentage or fixed amount, deposits already received deducted from the balance due.
- Bilingual invoices: document in French or English, in one click, whatever the tool's language.
- Currencies: CAD, USD or EUR for clients outside Canada.
- Logo and numbering: your branding, and a number that auto-increments with each new invoice.
- Vector PDF in Letter format, crisp in print and on screen.
Mandatory invoice content in Quebec
Good news: under the GST and QST regimes, no specific invoice template is imposed (apart from special rules for restaurants and taxis). However, Revenu Québec requires that specific information appear on the invoice so your business client can support their input tax credit claims (ITCs and ITRs). The requirements increase with the total value of the sale, taxes included:
| Information | Under $100 | $100 to $499.99 | $500 or more |
|---|---|---|---|
| Supplier's name (or trading name) | Required | Required | Required |
| Invoice date | Required | Required | Required |
| Total amount of the invoice | Required | Required | Required |
| Amount of each applicable tax | QST only | Required | Required |
| Supplier's GST and QST registration numbers | — | Required | Required |
| Buyer's name (or their agent's) | — | — | Required |
| Payment terms | — | — | Required |
| Description sufficient to identify the good or service | QST only | QST only | Required |

In the generator, these fields carry a “required” badge (with the applicable threshold), and tax amounts automatically appear on separate lines. The address, email and invoice number are not legally required, but remain strong business practices — the sequential number, in particular, is what accountants and auditors look at.
GST and QST: what to charge, at which rate
In Quebec, a business registered for the tax files collects, on most goods and services:
- GST (federal tax): 5%;
- QST (Quebec tax): 9.975%;
- for an effective total of 14.975%, each tax being calculated on the pre-tax amount (after discount).
Both taxes appear on separate lines, with your registration numbers. If you bill a client in another province, the place of supply generally determines the applicable tax — the tool's province selector adjusts the rates accordingly (13% HST in Ontario, 14% in Nova Scotia, 15% in New Brunswick, and so on).
To break down a tax-included amount or double-check a calculation, use our GST/QST calculator.
Under $30,000 in revenue? The small supplier rule
If your taxable sales stay under $30,000 over four consecutive calendar quarters, you are generally a small supplier: GST/QST registration is optional, and as long as you are not registered, you do not collect any tax on your invoices.
In the tool, simply turn off "I charge sales taxes": the mention "No tax collected — small supplier (not registered)" is added automatically, so the client understands why no tax appears.
Once you cross the threshold (or if you register voluntarily to recover the taxes paid on your expenses), turn taxes back on and enter your numbers — they will be remembered for all your future invoices.
Invoicing through a corporation
An invoice issued by a corporation is made out under the corporation's full legal name ("Tremblay Studio Inc.", "9999-9999 Québec inc."), ideally with its NEQ, and with the corporation's GST/QST numbers if registered. The corporation — not you personally — sells, collects and reports the income.
Billing through a corporation also means: limited liability (your personal assets are separate), a more credible image with clients, and the option of keeping profits taxed at the reduced corporate rate. To compare your situation, see when to incorporate in Quebec and the real cost of incorporating, or estimate the tax gap with our income tax calculator.

Invoicing best practices
- Number sequentially (001, 002, 003… or 2026-001): never the same number twice, no unexplained gaps — that is what tax authorities and accountants look at.
- Set a clear due date: "net 30 days" is the norm; "due on receipt" for small amounts. An invoice without a deadline is an invoice paid late.
- Ask for a deposit (25 to 50%) on larger mandates: the tool deducts it and shows the remaining balance.
- State the payment method: an Interac e-Transfer with the email address right on the invoice speeds up payment.
- Keep your invoices for at least six years: that is the retention period required for tax records. The downloaded PDF files easily by year.
- Stay consistent: same template, same logo, same terms from one invoice to the next — that is what reads as "established business" rather than "weekend project".
Frequently asked questions
Is the invoice generator really free?
Yes. No account, no invoice limit, no watermark over your amounts. Your information is saved in your browser only — nothing is sent to our servers.
How do I calculate GST and QST on an invoice?
You add 5% GST and 9.975% QST on the subtotal after discount, for an effective total of 14.975%. The generator applies these rates automatically and shows each tax on its own line.
Do I have to charge taxes if I earn less than $30,000?
As a general rule, no: under $30,000 of taxable sales over four consecutive quarters, you are a "small supplier" and registration is optional. As long as you are not registered, you do not collect taxes — the tool then adds the appropriate mention.
Which numbers must appear on my invoice?
Your GST number (123456789 RT0001) and QST number (1234567890 TQ0001), whenever you collect taxes. They let your business client claim input tax credits (ITCs/ITRs), and are required in particular on invoices of $100 or more.
Can I make an invoice in French or in another currency?
Yes: the document language switches in one click (FR/EN), and the currency can be CAD, USD or EUR.
Is my billing data sent to a server?
No. The invoice, the PDF and your draft (contact details, logo, tax numbers) stay on your device.
Does an incorporated business invoice differently?
The content is the same, but the invoice is issued under the corporation's full legal name, ideally with its NEQ, and with its tax numbers if registered. Billing through a corporation protects your personal assets — see what it changes below.
Invoice under your own corporation's name
