Best Free Invoice Apps in Canada: 4 Options Compared for 2026

The best free invoice app in Canada depends on what you expect the word "free" to include. One product may create a PDF without an account. Another may save unlimited invoices but include bookkeeping. A third may limit annual volume. A payment-led app may charge nothing monthly but earn money when the customer pays online.

This guide compares Just Invoice, Wave, Zoho Invoice, and Square Invoices for Canadian freelancers, independent contractors, and small service businesses. Just Invoice publishes the comparison and has an obvious commercial interest. The recommendations therefore use public limits, identify where another product is stronger, and avoid pretending that one free workflow fits everyone.

The details were reviewed on August 28, 2026. Vendors can change free limits, processing fees, supported features, or eligibility. Check the linked official pages before moving your client records.

Quick answer

There is no universal winner. Choose based on the information you want saved, the financial scope you want around the invoice, and how customers actually pay.

What "free invoice app" can mean

A 30-day trial is useful, but it is not a permanent free plan. A $0 monthly plan can still cost money when card payments are processed. A no-account PDF can be genuinely free while offering no history. Compare the full workflow instead of only the price badge.

Just Invoice guest generator

Just Invoice is made in Canada for Canadian estimates, invoices, taxes, payment instructions, and PDFs. The guest generator creates unlimited invoice and estimate PDFs without an account. It does not save the business, client, item, or document after the guest session, so it is best for someone who wants a quick document and accepts re-entering the details later.

The generator supports Canadian tax types and a bilingual interface. It can show Interac e-Transfer instructions clearly, which is useful when the client will pay outside the app. The free guest workflow is not bookkeeping and does not include saved invoice status, recurring invoices, receipt capture, mileage, payroll, or a general ledger.

Premium begins with a 30-day trial and then costs $8 CAD per month, plus applicable taxes. It adds saved businesses, clients, products, estimates, invoices, email delivery, branding, and optional Stripe Connect card-payment links. Treat Premium as a paid plan, not part of the permanent free comparison.

Choose the guest generator when you need a professional Canadian PDF now and do not need the app to remember it. Open invoice generator to test the real workflow.

Wave Starter

Wave's official pricing page lists Starter at $0 with unlimited estimates, invoices, bills, and bookkeeping records. It also lists a mobile invoicing experience and optional online payments. That is a stronger free saved workflow than Just Invoice's guest generator because the records remain in an account.

Wave is the best starting point in this group when free invoices should feed directly into basic bookkeeping. The trade-off is scope: users enter a financial system with transactions and accounting records rather than a narrowly focused PDF generator. Automated bank imports, receipt capture, and automated late reminders are among the capabilities promoted in the paid Pro plan.

Online payments carry processing fees. Review the current Canadian card and bank-payment terms on Wave's site instead of treating the $0 subscription as a promise that every transaction is free. Just Invoice vs Wave Canada | Pricing & Features (2026) provides a more detailed comparison of guest PDFs, saved records, Interac, and accounting scope.

Zoho Invoice

Zoho's Canadian pricing page states that Zoho Invoice is free and includes invoices, quotes, recurring invoices, payment reminders, expenses, time tracking, customer portals, reports, and mobile apps. Its current FAQ publishes limits of two users, three projects, and 500 invoices per year, with Zoho branding included.

That makes Zoho Invoice a strong feature-per-dollar choice for a freelancer who wants saved records, recurring billing, time sheets, and mobile apps without a monthly invoice subscription. The 500-invoice limit is generous for many solo businesses but may matter to a high-volume service operation. The surrounding Zoho ecosystem can be an advantage when a business already uses its CRM or accounting products.

Canadian users should test their exact GST/HST or GST/QST setup, French terminology, PDF layout, and preferred payment method. A globally capable invoice app is not automatically configured for every Canadian provincial workflow.

Square Invoices Free

Square's Canadian invoice pricing page lists a Free plan at $0 per month with unlimited invoices, estimates, and contracts. It also includes recurring invoices, reminders, status tracking, deposits, digital receipts, and card collection. The same page publishes the current processing rates for online and in-person payment methods.

Square is the strongest fit in this group when the invoice is primarily a route into Square payments or an existing Square customer and point-of-sale system. The invoice subscription can be free while a paid card transaction still has a percentage and fixed charge. Custom templates, custom fields, project folders, batch invoices, and milestone schedules are among the features reserved for Square Invoices Plus at the time reviewed.

For a contractor paid mainly by Interac e-Transfer, compare the cost and clarity of a payment-led invoice against simply placing the Interac instructions on a PDF. For a business already taking Square payments in person, keeping invoices in the same system may be worth more than a narrower invoice tool.

Canadian tax checklist

Every app still depends on correct inputs. Before sending a real invoice

1. Confirm whether you are registered and allowed to collect the tax.

2. Determine the place of supply and the tax treatment of what you sold.

3. Add the relevant GST/HST and provincial registration numbers.

4. Verify the taxable base, rate, rounding, subtotal, tax, and total.

5. Inspect the final PDF rather than trusting the form preview alone.

The CRA's input tax credit documentation table lists the information a purchaser needs to support an ITC. The current table uses tiers under $100, $100 to $499.99, and $500 or more. At $100 or more, the supplier's GST/HST registration number is included; at $500 or more, the buyer name, description, and payment terms are also included.

Software cannot decide registration, exemption, zero-rating, or place of supply from a province selector alone. Use Tax Invoice Requirements Canada: GST/HST Checklist for the documentation checklist.

Quebec and French test

For Quebec, create a $1,000 taxable example in French. The general calculation should show TPS of $50.00 and TVQ of $99.75, for a $1,149.75 total. Revenu Québec confirms TPS at 5% of the selling price and TVQ at 9.975% of the price excluding TPS in its basic application rules.

Then inspect facture, soumission, échéance, TPS, TVQ, virement Interac, decimal formatting, registration fields, and the client email. A language selector is only useful when the entire customer document reads naturally.

Run the same-invoice test

Create the same real invoice in your two strongest candidates

• one existing client;
• labour plus a material or expense line;
• the actual provincial tax combination;
• an estimate or work-order reference;
• a calendar due date;
• the payment method the client will use;
• a second invoice for the same client.

Compare the PDF, data re-entry, saved history, payment fee, mobile flow, export, and cancellation process. The second invoice exposes more friction than a feature list.

Which free app should you choose?

Choose Just Invoice for unlimited no-account Canadian PDFs and clear Interac instructions when saved guest history is unnecessary. Choose Wave for free saved invoicing with bookkeeping. Choose Zoho Invoice for a broad free invoice account with published usage limits. Choose Square for free invoicing connected closely to card collection.

For paid and accounting-led options, continue to Best Invoicing Software Canada 2026 for Contractors. For the contractor document itself, use Contractor Invoice Template Canada: Free Example (2026).

Is there a completely free invoice app in Canada?

A: Yes, but the free models differ. Just Invoice offers no-account PDFs without saved data. Wave, Zoho Invoice, and Square publish $0 account options with different scope, limits, and payment economics.

Which free invoice app saves clients and invoices?

A: Wave Starter, Zoho Invoice, and Square Invoices Free publish saved account workflows. Just Invoice's guest generator deliberately does not save guest data.

Are free invoice apps free when clients pay by card?

A: Usually the invoice subscription and payment processing are separate. Review the current percentage, fixed fee, payout timing, refund terms, and card types before enabling online payments.

What is the best free invoice app for a Canadian contractor?

A: Test Just Invoice when PDFs, Canadian taxes, and Interac are central; Wave when bookkeeping matters; Zoho when time and recurring billing matter; and Square when card collection is central.
