Invoice Software in Canada: How to Choose an Invoicing App

Short answer: Good invoice software for a Canadian freelancer or contractor does four things. It prints every detail the Canada Revenue Agency (CRA) expects, including your GST/HST number and the tax charged on sales of $100 or more. It lets you set the rate for each client, from 5% GST to 15% HST. It keeps estimates, invoices and receipts together. And it tells you plainly where your records are stored. Price comes last: free, monthly and one-time models can all work.

This guide is for self-employed people in Canada (sole proprietors, freelancers and contractors) choosing a tool for the 2026 tax year. The rules come from the CRA; software only makes them easier or harder to follow. What goes on the invoice itself is covered in how to invoice in Canada as a freelancer, and if you would rather start with a document than an app, the Canadian invoice template has layouts you can copy.

What should invoice software do for a Canadian freelancer?

It should produce a complete invoice quickly and keep a readable copy for the six years the CRA expects you to hold records.

What to check	Why it matters in Canada
A GST/HST number field that prints on the invoice	Required on sales of $100 or more once you are registered
Tax rate set per invoice or per client	The rate follows the place of supply, usually the client’s province for services
Room for a second tax line	British Columbia, Saskatchewan, Manitoba and Quebec have a provincial tax separate from the GST
A no-tax mode	Small suppliers who are not registered do not charge GST/HST
Client name, description and payment terms	Required on sales of $500 or more
Estimates that become invoices	Saves retyping and keeps the price the client agreed
Receipts and expenses	Your T2125 expenses and input tax credits depend on them
Exports	Your accountant, and the CRA if it asks, need readable copies
Where the data is stored	The CRA has rules on where records are kept

The first five rows are the Canadian layer: a generator built for another market may have a “sales tax” box but nowhere to print a GST/HST number.

Does the invoice software handle GST/HST properly?

It does if it prints the details the CRA’s information bands call for and lets you change the rate whenever the place of supply changes.

Total of the sale	The invoice must show
Under $100	Your business or trading name, the invoice date and the total
$100 to $499.99	Also your GST/HST registration number, the tax charged (or a statement that the price includes it), and which items are taxable if exempt items also appear
$500 or more	Also the client’s name or trading name, a brief description of the work, and the payment terms

These bands come from the CRA’s documentary requirements for claiming input tax credits. Business clients need them to claim input tax credits. Your GST/HST number is your nine-digit business number, the letters RT and a four-digit reference, such as 123456789 RT0001, so the field needs room for all 15 characters.

The rate is 5% GST in Alberta, the territories and the provinces with their own sales tax, 13% HST in Ontario, 14% in Nova Scotia and 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, per the CRA’s GST/HST rates page.

Worked example. An Ontario web developer bills $3,000 to a client in Calgary and $3,000 to one in Halifax. Under the CRA’s place-of-supply rules, a service is generally supplied in the province of the client’s address, so the first invoice carries 5% GST ($150) and the second 14% HST ($420). One fixed rate in an app’s settings is how the wrong tax ends up on an invoice. Software only multiplies; the province of the supply is your call, and the formulas are in how to calculate GST/HST.

Do you need estimates and receipts in the same app?

If you quote before you work or buy materials for jobs, yes: keeping them together saves retyping and keeps the evidence for your deductions next to the income it relates to.

The CRA’s business records page says your income records must show the date, amount and source of each payment, supported by original documents such as sales invoices. The expense side works the same way: receipts back up the costs on your T2125 and, once you are registered, your input tax credits.

Freelancers billing by the hour often need only invoices and a place for receipts. Contractors who quote, buy materials and invoice in stages get more from an app where an accepted estimate becomes the invoice and each job holds its own receipts. What counts as a valid receipt is in self-employed expenses and receipts in Canada.

Where is your invoice data stored, and does the CRA care?

The CRA does care: it expects records to be kept in Canada and to stay readable, so where an app stores your data is a selection criterion, not only a privacy preference.

On its where to keep your records page, the CRA says records must be kept at your place of business or your residence in Canada unless it gives you written permission to keep them elsewhere. It adds that records kept outside Canada and accessed electronically from Canada are not considered to be kept in Canada. Electronic records must be in an accessible and readable format, and the CRA advises making backups that can be restored in a usable format.

Model	Where your records live	What to check
Cloud invoicing or accounting app	On the vendor’s servers; you sign in with an account	Where the servers are, whether you can export everything, what happens to your data if you stop paying
On-device app	On your phone; usually no account	How you keep a copy if the phone is lost or replaced
Template in Word, Google Docs or a spreadsheet	Wherever you save the files	Numbering discipline and a backup of the folder

Whichever you choose, keep the PDF of every invoice you send and an export that opens without the app.

Do you need invoicing software or a full accounting package?

Most sole proprietors with a handful of clients need invoicing plus receipts, not a full accounting package; bookkeeping software earns its cost once you have payroll, inventory or many bank transactions to reconcile.

Your situation	Usually enough
A few invoices a month, few expenses	A template or an invoicing app
You quote jobs, buy materials and invoice in stages	An invoicing app with estimates, jobs and receipts
You want bank transactions imported automatically	Cloud accounting software with a bank connection
Employees, inventory, or an accountant who wants a live ledger	A small business accounting package

If you are close to the $30,000 small supplier threshold, read registering for GST/HST first, so the tool you choose can add a tax line the day you need it.

How much should invoice software cost?

Anything from nothing to a monthly fee; compare the total over the years you will use it, and check what the free version leaves out.

Pricing model	What to watch for
Free	Limits on invoices or clients, a branding footer, features held back for paid plans
Monthly or annual plan	The cost repeats; check what happens to your records if you cancel
One-time purchase	What is included, and whether the app keeps working without further payments

A plan at, say, $15 a month is $180 a year and $900 over five years; a one-time purchase is paid once. Neither is automatically better: a monthly plan can pay for itself if bank feeds save you hours, and a free tool is enough if it prints every field above. Whatever you pay is a business cost; see the FAQ below on deducting it.

How do you test invoice software before you commit?

Put a few test invoices through it first.

1. Make a $150 invoice to an Ontario client: your GST/HST number and a 13% HST line should print.
2. Make a $600 invoice to an Alberta client: check the 5% rate, the client’s name, the description and the terms.
3. Turn an estimate into an invoice.
4. Switch tax off, as before registering, and check that no tax line appears.
5. Cancel an invoice and check that its number stays in the sequence.
6. Export everything and open the files on another device.
7. Read the privacy page: account, bank connection, where the data is stored.

…and where does Keel fit?

Keel: Invoice Maker & Receipts, by Ilura Technology OÜ, is an iPhone app for people who work for themselves. An accepted estimate becomes the invoice in one tap; each job keeps its quotes, receipts, expenses and invoices together; invoices go out as PDFs; and “who owes you” prepares reminder drafts you review and send yourself. Nothing is sent automatically.

It is the on-device model from the storage table: no account, no bank connection, no cloud sync, and an App Store privacy label of “Data Not Collected”. The trade-off is that keeping copies off the phone is your job. Keel is a record keeper, not a compliance tool: it does not check invoices against the CRA’s requirements, file GST/HST returns, connect to the CRA or work out the tax you owe, so run the seven tests on it like any other app.

Keel is free with no invoice limit; free invoices carry a small “Made with Keel” footer. Keel Lifetime is a one-time purchase ($249.99 USD; the App Store shows your local price) that adds custom branding, a signature, premium templates and accountant-ready exports and advanced reports. Keel: Invoice Maker & Receipts on the App Store. More Canadian guides are in the Canada hub.

Frequently asked questions

Is there free invoice software in Canada? Yes: templates in Word or Google Docs, browser-based invoice generators and apps with a free version. Check what the free version leaves out, such as an invoice limit, a branding footer or exports, and that it can print your GST/HST number. The free invoice generator on this site builds a PDF in your browser, with CAD as a currency option and a tax-rate field.

Can I put my logo on invoices made with an app? Most invoice generators and apps let you add a logo, though some keep it for paid plans. The CRA does not require one: what matters is your business name, your GST/HST number once you are registered, and the other details for the size of the sale. In Keel, custom branding is part of Keel Lifetime, and free invoices carry a small “Made with Keel” footer.

Is invoicing software tax deductible in Canada? Generally yes, when you use it to earn business income. The CRA treats software costs as either current or capital: current costs are deducted in the year, capital costs through capital cost allowance. Purchased application software generally falls in Class 12, at a 100% rate. Which treatment fits a monthly plan or a one-time purchase depends on the facts, so confirm it with your accountant.

Do I need accounting software as a sole proprietor? No rule requires it. The CRA requires records that support your income and expenses, kept in Canada, readable and held for six years; a sole proprietor with a few clients can meet that with invoices, receipts and a yearly summary. Accounting software becomes worthwhile when you have employees, inventory, many bank transactions to reconcile, or an accountant who wants a live ledger.

Can invoice software file my GST/HST return? Invoicing apps generally do not file returns; you or your accountant file with the CRA. What a good tool should give you is the two totals a return needs: the GST/HST charged on your invoices and the tax paid on your business purchases. The filing steps are in how to file a GST/HST return.
