Invoice vs Receipt
Guide • Canada • last updated October 2026
The difference between an invoice and a receipt, when to send each, and what each must include. With free generators for both.
Invoices and receipts are often confused, but they do different jobs. Knowing when to send each keeps your records clean and your clients clear on what they owe and what they have paid. You can make both for free with the invoice generator and the receipt generator.
What an invoice is
An invoice is a request for payment. You send it after delivering goods or services, and it lists what was provided, the amount owed, the tax, and the due date. It is the document that starts the clock on getting paid.
What a receipt is
A receipt is proof of payment. You send it after the client has paid, confirming the amount received and the date. Clients use receipts for their own bookkeeping and expense claims.
The key differences
- Timing: an invoice comes before payment, a receipt after.
- Purpose: an invoice asks for money, a receipt confirms it was paid.
- Content: an invoice shows a balance due, a receipt shows a zero balance.
When to send each
Send an invoice when work is complete or on your agreed schedule. Send a receipt once payment clears, especially if the client asks or needs it for taxes. For cash or in-person sales, a receipt may be all you need.
A worked example
You finish a $1,000 job in Ontario, send an invoice for $1,130 including 13% HST, and the client pays. You then send a receipt for $1,130 marked paid, with the date, so both of you have a clean record.
Common mistakes to avoid
- Using the word receipt on a document that still shows a balance due.
- Not issuing a receipt when a client needs one for expenses.
- Leaving the tax off either document.
Why the distinction matters at tax time
For your records and your client's, the two documents play different roles. An invoice supports the revenue you report and the GST/HST you must remit. A receipt supports an expense claim and proves the money changed hands. Mixing them up, or skipping the receipt, can leave gaps that make bookkeeping and any CRA review harder than it needs to be.
What each document should show
An invoice shows a balance owing, with the due date and terms. A receipt shows a zero balance with the amount paid, the date, and the method. Both should carry your business details and, where you are registered, your tax numbers, so either can stand on its own as a record.
Digital records and retention
Keep digital copies of both, organized by client and date. The CRA generally expects records to be retained for six years. Invoicing software that stores invoices and marks them paid, then issues a matching receipt, keeps the trail complete without extra filing on your part.
Quick reference
- Sent before payment, shows a balance due: invoice.
- Sent after payment, shows zero balance: receipt.
- Both carry your details and tax numbers.
- Keep both for at least six years.
Using both in your bookkeeping
Invoices and receipts are two sides of the same transaction in your books. The invoice records the sale and the tax you owe; the matching receipt closes it out when payment lands. Keeping both, linked by the invoice number, gives you a clean audit trail and makes reconciliation at month-end quick instead of painful.
Good invoicing software issues the receipt automatically once an invoice is marked paid, so the pair always matches and nothing is forgotten.
Quick decision guide
- Need to request payment? Send an invoice.
- Confirming money received? Send a receipt.
- Client needs proof for expenses or taxes? Send a receipt.
- Keep both for at least six years.
Frequently asked questions
What is the difference between an invoice and a receipt?
An invoice is a request for payment sent before the client pays, showing a balance due. A receipt is proof of payment sent after, showing a zero balance. You usually send an invoice first, then a receipt once it is paid.
Do I have to give a receipt in Canada?
You should provide a receipt when a client pays, especially if they ask or need it for expense or tax purposes. It confirms the amount and date and helps both sides keep clean records, which the CRA expects you to retain.
Can one document be both an invoice and a receipt?
Not really, because they show different states: one a balance owing, the other a zero balance paid. For a paid-on-the-spot sale a receipt alone is often enough, but when you bill and are paid later, issue both.
