Quotation vs Invoice vs Receipt: What's the Difference?

Running a business means issuing the right document at the right time. A quotation, invoice, and receipt are three distinct business documents — each used at a different stage of a transaction. Using them correctly builds professionalism, ensures legal compliance, and keeps your financial records clean.

What Is a Quotation?

A quotation (also called a quote or estimate) is a formal document sent to a potential customer BEFORE any work begins or any goods are delivered. It proposes the cost, scope, and terms of a job so the customer can review and approve.

A quotation is NOT a payment request — it is a price proposal.

Key Details on a Quotation: - Unique quote number (e.g. QUOTE-0001) - Date issued and validity expiry date (e.g. "Valid for 30 days") - Seller and prospective client details - Itemized breakdown of products or services with quantities and unit rates - Applicable taxes and discounts - Payment terms (e.g. 50% deposit required upon acceptance) - Terms and conditions or project scope notes

What Is an Invoice?

An invoice is a formal payment request sent AFTER work is completed or goods have been delivered. It tells the customer exactly how much they owe and when payment is due. It creates a legal payment obligation.

An invoice is NOT proof that payment has been made — it is a demand for payment.

Key Details on an Invoice: - Unique invoice number (e.g. INV-0001) - Invoice issue date and payment due date - Seller and buyer business details - Itemized list of completed work, products, quantities, and unit prices - Applicable taxes and discounts - Total amount due - Payment instructions (bank account, SWIFT/IBAN, payment link)

What Is a Receipt?

A receipt is an official written confirmation that a buyer has completed payment — either fully or partially. It is issued AFTER money changes hands and serves as legally recognized proof of payment.

A receipt IS proof of payment. It documents the settled transaction.

Key Details on a Receipt: - Unique receipt number (e.g. RECEIPT-0001) - Date payment was received - Seller and buyer details - Itemized list of goods or services paid for - Payment method (Cash, Card, Bank Transfer, Online) - Amount paid and any remaining balance - PAID or PARTIALLY PAID stamp

The Complete Business Transaction Workflow

The three documents follow a natural sequence in every business transaction:

Step 1 — Send a Quotation Before any work starts, send a quotation outlining your pricing, scope, and terms. The client reviews the quote and either approves, negotiates, or declines. A quotation tells the client: "Here is what I will charge."

Step 2 — Perform the Work Once the client accepts the quotation, complete the agreed-upon work or deliver the goods.

Step 3 — Send an Invoice After delivery or project completion, issue an invoice requesting payment. The invoice tells the client: "The work is done — please pay this amount by this date."

Step 4 — Issue a Receipt Once the client pays (fully or as a deposit), issue a receipt confirming the payment was received. The receipt tells the client: "Thank you — I confirm I received your payment."
