Understand the method

A quote or estimate proposes a price before or during the decision to buy. An invoice requests payment for goods or services under the relevant arrangement. A receipt usually confirms that payment was received.

Some businesses use deposits, pro forma invoices, credit notes or tax invoices as well. These have different meanings and requirements depending on local rules.

Worked example

A decorator estimates a job at $600. After completing the agreed work, they send a $600 invoice. After receiving payment, they may issue a receipt showing $600 paid.

What people often get wrong

Do not label an unpaid invoice “receipt” if it has not been paid. Likewise, a quote does not necessarily authorize a purchase until accepted.

A practical way to use this

Keep document labels distinct and retain the accepted quote and final invoice together for your records.

Frequently asked question

Is a quote the same as an invoice? No. A quote presents a proposed price, while an invoice presents an amount to be paid or recorded for a transaction. Whether any document has legal effect is outside the scope of this guide.

A quote, invoice and receipt answer different questions

A quote describes a proposed price before work is accepted. An invoice requests or records the amount to be paid for goods or services. A receipt confirms that payment has been received. One document is not automatically a substitute for another.

Apply it to your own task

For example, a designer might send a $500 estimate, later issue a $500 invoice, and after receiving payment send a receipt noting the amount and date. Use labels that reflect the actual stage of the transaction.
