1. What is an Invoice?
An invoice is an official payment request issued by a seller to a buyer before payment is made. It acts as an itemized request for payment for goods delivered or services rendered.
Issued By: The seller or service provider.
Timing: Sent after order completion or upon reaching a contractual milestone.
Purpose: Establishes a legal obligation for the buyer to pay within an agreed window (e.g., Net 30).
2. What is a Bill?
A bill is essentially the exact same document as an invoice, but viewed from the customer's perspective. When a service provider sends you an invoice, you receive it as a bill to be paid.
In everyday commercial language, "bills" typically refer to immediate payment requests for recurring utilities or direct consumer transactions (e.g., restaurant bills, electric bills), whereas "invoices" imply formal B2B terms.
Issued By: Received by the buyer.
Timing: Typically due immediately or within a short payment window.
Purpose: Represents an upcoming cash outflow for the recipient.
3. What is a Receipt?
A receipt is proof of payment. It is generated after the payment has been successfully completed and settled.
Issued By: The seller.
Timing: Issued immediately after funds are received.
Purpose: Serves as proof of payment for both parties for tax and auditing records.
