Receipt vs Invoice: What’s the Difference (and What CRA Expects)

Short answer: The receipt vs invoice difference is timing and purpose. An invoice is a request for payment: you issue it after doing the work or delivering the goods, and it states what is owed and when. A receipt is proof that payment was made, issued once the money arrives. The Canada Revenue Agency (CRA) treats both as records: invoices you issue back up your income, while receipts and supplier invoices you collect back up your expenses and any GST/HST input tax credits. Keep both for six years.

This guide is for self-employed people in Canada (sole proprietors, freelancers and contractors) and reflects CRA record-keeping and GST/HST guidance as it applies in the 2026 tax year. It covers what each document is, when you send which, and what the CRA expects you to keep. The step-by-step of building an invoice is in how to invoice in Canada as a freelancer; the deduction side of receipts is in self-employed expenses in Canada.

What is an invoice?

An invoice is a document a seller sends a buyer that lists what was supplied, what it costs, and how and when to pay.

In plain terms, an invoice says “you owe me this”. A complete one usually shows:

• your name or business name and contact details;
• the client’s name and address;
• a unique invoice number and the invoice date;
• a description of the work or goods, with quantities and rates;
• the subtotal, any GST/HST or provincial sales tax shown separately, and the total due;
• payment terms: the due date and how to pay.

An invoice creates a record of income for you and a record of an expense for your client. It does not prove anyone has paid. Until the money arrives, it is an amount owed, which is why you track unpaid invoices separately from paid ones.

An invoice is also different from an estimate or quote, which comes before the work and proposes a price. The usual order is estimate, then invoice, then receipt.

What is a receipt?

A receipt is a document that confirms a payment has been received, showing who was paid, how much, when, and for what.

A receipt says “you paid me this”. You get one every time you buy something: the till slip at the hardware store, the emailed order confirmation from an online shop, the stamped invoice from a supplier. You give one when a client pays you and asks for proof, or when you are paid on the spot.

For your own records, the receipts you collect matter most. They are the evidence behind every expense you deduct on your T2125, and, if you are registered for GST/HST, behind every input tax credit you claim.

Receipt vs invoice: what’s the difference?

The difference is that an invoice comes before payment and asks for it, while a receipt comes after payment and proves it.

	Invoice	Receipt
Purpose	Requests payment	Confirms payment
When it is issued	After the work or sale, before payment	When or after payment is received
What it says	”You owe this amount by this date"	"This amount was paid on this date”
Includes payment terms	Yes: due date, methods, late terms	No, but often the payment method
Amount shown	The total due	The amount received
For you, it supports	Your income (invoices you issue)	Your expenses (receipts you collect)
Numbering	Invoice number, in sequence	Often quotes the invoice number
Can be the same document	Yes, once it is marked paid	Yes, a paid invoice can serve as one

In everyday use the line blurs. A supplier invoice you have already paid, marked “Paid” with a date and method, does the job of a receipt. A till receipt for a cash sale does the job of both, because the sale and the payment happen at the same moment.

When should you send an invoice, and when a receipt?

You send an invoice when you want to be paid, and a receipt when you have been paid and the client wants proof.

For most freelancers and contractors who bill on terms, the flow is:

1. Estimate or quote before the job, if the client wants a price first.
2. Invoice when the work is done, or at agreed stages such as a deposit and a final payment.
3. Receipt or paid invoice when the money arrives, if the client asks for one or paid in cash.

If you are paid on the spot, at a market stall or by a homeowner at the end of a job, a single receipt that shows what was supplied, the tax and the total covers both steps. If a client pays a deposit, invoice for the deposit and issue a final invoice that shows the deposit already paid, so the two documents reconcile.

What does the CRA expect you to keep?

The CRA expects you to keep records that support every amount on your return: the invoices you issue for your income, and the receipts and supplier invoices for your expenses.

In practice that means three sets of documents:

• Income records. A copy of every invoice you issue, plus anything showing the money arriving: deposit records, payment-processor reports, cash records. Keep cancelled invoices too, or the credit notes that reverse them, so your numbering has no unexplained gaps.
• Expense records. The receipt or supplier invoice for each purchase. A bank or card statement shows that money left your account, but usually not what you bought or the tax you paid, so on its own it is weak evidence.
• Supporting records. Contracts, estimates the client accepted, and a logbook if you claim vehicle costs, the standard set out in self-employed vehicle expenses in Canada.

How long: generally six years from the end of the last tax year the records relate to; for a self-employed individual, the tax year is the calendar year. If you file a return late, the six years run from the date you file it, and records tied to an objection or appeal must be kept until it is resolved. The CRA sets this out in where to keep your records and for how long. Electronic copies, including photos and PDFs, count if they stay complete and readable, and thermal till paper fades, so photograph receipts on the day.

What GST/HST information does a receipt or invoice need?

If you are registered for GST/HST, the information a purchase document must show to support an input tax credit depends on the size of the sale: the bigger the total, the more it has to contain.

The CRA sorts this into three bands by the total amount paid or payable:

Total of the sale	What the document must show
Under $100	The supplier’s business or trading name, the invoice date (or the date the GST/HST was paid or payable), and the total amount paid or payable
$100 to $499.99	All of the above, plus the GST/HST charged (or a statement that the price includes it at the applicable rate), which items are taxable or exempt if both appear, and the supplier’s GST/HST registration number
$500 or more	All of the above, plus the buyer’s name or trading name, a brief description of the goods or services, and the terms of payment

These bands have applied since April 20, 2021, and the full wording is in the CRA’s documentary requirements for claiming input tax credits and its input tax credits page.

Two things follow for you:

• As a buyer, a receipt of $100 or more that is missing the supplier’s GST/HST number can cost you the input tax credit on that purchase. If a supplier’s number looks wrong, you can check it with the GST/HST registry lookup.
• As a seller, once you are registered your invoices need the same details, including your GST/HST number from $100, so business clients can claim their credits. If you are not registered, you do not charge GST/HST and have no number to show; when that changes is covered in registering for GST/HST.

The same table applies whether the document is called an invoice, a receipt or a sales slip. The CRA looks at the information on it, not the title at the top. The other Canadian GST/HST and record-keeping rules are collected in the Canada guides hub.

…and where does Keel fit?

Keel: Invoice Maker & Receipts is an iPhone app that handles both sides of this article. You write an estimate, and when the client accepts it, it becomes the invoice in one tap; the invoice goes out as a PDF. The receipts and expenses you collect are filed under the same job, next to the invoice they relate to, and a “who owes you” view shows which invoices are still unpaid, with reminder drafts you review and send yourself. Nothing is sent automatically.

Keel is a record keeper, not a compliance tool: it does not check your documents against the CRA’s GST/HST requirements, file returns or connect to the CRA, so the fields on each invoice are still yours to get right. Records stay on the iPhone: no account, no bank connection, no cloud sync, and an App Store privacy label of “Data Not Collected”. It is free with no invoice limit, and free invoices carry a small “Made with Keel” footer; Keel Lifetime, a one-time $249.99 USD purchase (the App Store shows your local price), adds custom branding, signature, premium templates and accountant-ready exports and advanced reports.

Frequently asked questions

Is an invoice the same as a receipt? No. An invoice asks for payment and states what is owed and when it is due; a receipt confirms that payment was made. They can become the same document when an invoice is marked paid, with the date and payment method, or when a cash sale is recorded on a single slip, but an unpaid invoice is never proof of payment.

What is the meaning of invoice? An invoice is a commercial document a seller issues to a buyer, listing the goods or services supplied, the quantities and prices, any sales tax, the total due and the payment terms. For a self-employed person it is both the request that gets you paid and the record that supports the income you report to the CRA.

Can a paid invoice be used as a receipt? Yes. Mark the invoice as paid, add the payment date and method, and send it back to the client; for most purposes that is a valid receipt. Keep your own copy with the same invoice number, so the income record and the proof of payment match when you reconcile your books or the CRA asks to see them.

Is a bank statement enough instead of a receipt? Usually not on its own. A bank or credit card statement proves that money left your account, but it rarely shows what you bought, whether it was for the business, or how much GST/HST you paid. Keep the receipt or supplier invoice as the main record and treat the statement as backup that the payment happened.

Does a receipt need a GST/HST number? Only when the supplier is registered for GST/HST and the total is $100 or more. A supplier who is not registered must not charge GST/HST, so their receipt will have no number and no tax line. If you are registered and want to claim an input tax credit on a purchase of $100 or more, the supplier’s GST/HST registration number has to be on the document.
