Accounting software in Montreal: GST and QST invoices, French and English, one ledger

A Montreal business invoices with two taxes on every taxable sale — the federal GST and the Québec QST, each on its own line, each with its own registration number — in French, in English or in both, in Canadian dollars to the customer around the corner and in US dollars to the one in Vermont. It files nothing through its accounting software; Revenu Québec and the CRA have their own portals. What it needs from the software is an invoice that a business customer's bookkeeper accepts without a phone call, books that an accountant on Boulevard Saint-Laurent can open on a Tuesday, and a way to stop retyping receipts. KRONENWERK, operated from Québec for Canada, the United States and Europe, does exactly that — and this page says plainly what it does not do.

The Québec invoice, done right

Where GST or QST is charged, the invoice must show the seller's GST/HST registration number and QST registration number beside the tax, so the customer can claim its input tax credit and input tax refund. KRONENWERK prints GST and QST as two separate lines, each computed on the net, each with its own rate and amount, with both registration numbers on the document — never a merged 14.975 % line that totals correctly and tells the customer's bookkeeper the wrong thing about who was paid. If the company has no QST number on file and tries to charge QST, the invoice is refused before it exists, with the reason. The two lines are entered wherever an invoice is made: in the web form (the GST in the rate field, the QST — or a PST or RST — as the second tax beside it), through the API and through the AI assistant, each tax by name and rate. The tax rates themselves are yours to state: KRONENWERK computes with the rate you enter and checks that the number stands beside it. It does not determine the rate, because the rate turns on the place of supply, and a product that defaulted to 5 % because the federal rate is 5 % would be wrong for a sale to Toronto and wrong for a sale to Burlington.

The document is written in Canadian French or Canadian English — Facture, TPS, TVQ, Sous-total, Montant dû on one, Invoice, GST, QST on the other — from one source, not two translations that drift. Choosing the language of a document changes nothing about the company's country or taxes.

Beyond the island: Ontario, the rest of Canada, the United States

Montreal businesses sell everywhere. A customer in Ontario gets one HST line; a customer in British Columbia gets GST and, where PST applies, PST as a second line; a customer in Alberta gets GST alone. A customer in the United States, for a Canadian seller, is typically a zero-rated export: the invoice shows a GST/HST line at 0 % with the reason the seller states, so the document explains itself to both tax authorities. The customer's province is on the customer record, so KRONENWERK knows which structure the sale needs and warns when the invoice does not carry it; the rates are yours.

Currencies: the books can be kept in Canadian dollars while an invoice is issued in US dollars or euro; the customer's preferred currency is stored on the customer, and the ledger carries every line in both the transaction currency and the book currency.

What a small Montreal business actually spends time on

• Receipts and supplier bills. Photograph or forward them; they land in an inbox awaiting confirmation with the figures read as printed. With an AI assistant connected, "record this bill on the Dubois job" is the whole task.
• Jobs with many documents. A quote, the customer's PO, drawings, the supplier's bill, photos, the waybill, the invoice and the payment — one transaction, one number, inside the accounting.
• Chasing money. Receivables aged by how late, automatic reminders on a schedule you own (from the Business plan), and a payment page for customers who pay by card once you enable it.
• The accountant. Invite your CPA into the company; with the practice plan they see every client on one screen and open yours with the rights you gave. You end the engagement, not the firm.
• Two languages in the office. The interface exists in French and English; each member picks their own, and it changes nothing about the company.

What KRONENWERK does not do in Québec

• No determination of GST, HST, PST or QST rates. You enter the rate; the software computes and checks.
• No tax return and no filing with Revenu Québec or the CRA. The figures you need are in the reports; the filing is on their portals.
• No Québec chart of accounts shipped and no payroll. A chart of accounts ships for Germany only today; a Canadian chart is entered or imported.
• No signed-off bank connection yet. Statements are imported for reconciliation rather than fetched automatically.
• No advice on whether a supply is taxable, zero-rated or exempt. That is your accountant's call; the invoice states what you decided.

Switching from your current setup

From QuickBooks Online, Wave, Sage or a spreadsheet: export customers, suppliers, invoices, bills and a trial balance as of a date, upload them, map the columns, compare the totals, approve. The switching guide goes through it step by step, including what happens to old invoice numbers and to the accountant. Most businesses pick the first day of a quarter and are issuing from KRONENWERK the same afternoon.

Pricing, in Canadian dollars

Plans are priced per market, so a Montreal business sees and pays Canadian dollars, monthly or annually, with no conversion at checkout. Country-required invoicing, customers, suppliers, bills, expenses, attachments, payments and the core reports are in every plan; the practice plan is for the accountant, the Enterprise plan adds the API and the AI assistant connection. See the pricing page and the Canada page.
