Invoice vs Bill vs Receipt — What's the Difference?
What is an Invoice?
An invoice is a commercial document issued by a seller to a buyer, detailing the products, quantities, and agreed prices for products or services the seller has provided. Crucially, an invoice indicates that the buyer must pay the seller according to the specified payment terms.
Invoices are typically used in B2B (business-to-business) transactions where credit is extended. For example, a web designer finishes a website and sends an invoice to the client giving them 15 days to pay (Net 15 terms). In India, under GST, a "Tax Invoice" is a legal requirement to claim Input Tax Credit (ITC).
What is a Bill?
A bill is a request for payment that expects to be settled immediately. While it contains similar information to an invoice (what was purchased and the cost), it does not offer extended payment terms or credit.
Think of a restaurant: after you eat, the waiter brings you a "bill," and you are expected to pay before leaving. You don't get 30 days to pay for your dinner. Under Indian GST law, a "Bill of Supply" is issued (instead of a Tax Invoice) when a registered supplier is dealing in exempt goods/services or is registered under the Composition Scheme.
What is a Receipt?
A receipt is a document acknowledging that a person has received money or property in payment following a sale. It is the proof of payment.
A receipt is issued after the transaction is complete. When you pay an invoice, the seller might issue a payment receipt. When you pay a bill at a store, the cash register prints a receipt. Under GST, a "Receipt Voucher" must be issued when an advance payment is received before goods or services are supplied.

When to Use Which Document
Understanding the terminology helps keep your accounting clean and professional:
- Use an Invoice if you are a freelancer, agency, or B2B supplier providing goods/services and allowing the client time to pay (e.g., 7, 15, or 30 days). This is the standard for professional services.
- Use a Bill if you run a retail shop, cafe, or provide immediate consumer services where you expect the customer to pay right then and there.
- Use a Receipt immediately after a client pays you, especially for cash payments or when receiving advance payments.
