Written acknowledgment that a person has received money or property in payment
the song

A receipt (also known as a packing list, packing slip, packaging slip, (delivery) docket, shipping list, delivery list, bill of the parcel, manifest, or customer receipt) is a document acknowledging that a person has received money or property in payment following a sale or other transfer of goods or provision of a service. All receipts must have the date of purchase on them. If the recipient of the payment is legally required to collect sales tax or VAT from the customer, the amount would be added to the receipt, and the collection would be deemed to have been on behalf of the relevant tax authority. In many countries, a retailer is required to include the sales tax or VAT in the displayed price of goods sold, from which the tax amount would be calculated at the point of sale and remitted to the tax authorities in due course. Similarly, amounts may be deducted from amounts payable, as in the case of taxes withheld from wages. On the other hand, tips or other gratuities that are given by a customer, for example in a restaurant, would not form part of the payment amount or appear on the receipt. In some countries, it is obligatory for a business to provide a receipt to a customer confirming the details of a transaction. In most cases, the recipient of money provides the receipt, but in some cases, the receipt is generated by the payer, as in the case of goods being returned for a refund. A receipt is not the same as an invoice. There is usually no set form for a receipt, such as a requirement that it be machine generated. Many point of sale terminals or cash registers can automatically produce receipts. Receipts may also be generated by accounting systems, be manually produced, or generated electronically, for example, if there is no face to face transaction. To reduce the cost of postage and processing, many businesses do not mail receipts to customers unless specifically requested or required by law, with some transmitting them electronically. Others, to reduce time and paper, may endorse an invoice, account, or statement as "paid".

The practice in most shops at the point of sale is for a salesperson to scan or record the price of a customer's proposed purchases, including tax, discounts, credits, and other adjustments. In traditional situations and still in some family businesses today, the salesperson would then show the customer the summary, the invoice, for their agreement; but many shops today bypass this stage. The practice of presenting an invoice is most common in restaurants where a "bill" is presented after a meal. The salesperson would indicate to the customer (whether by way of an invoice or otherwise) the total amount payable, and the customer would indicate the proposed method of payment of the amount. Payment in cash is regarded as payment of the amount tendered, but payment by store account is not. After processing the payment, the salesperson would then generate in one document an invoice and receipt. If payment was made by a payment card, a payment record would normally also be generated. The invoice and receipt are the printed record of the transaction and are legal documents. The document may also include messages from the retailer, warranty or return details, special offers, advertisements, or coupons, but these are merely promotional and not part of the formal receipt.

Receipts may also be provided for non retail operations such as banking transactions.

Shops that use barcode readers may generate receipts with a barcode of the receipt identification number, which enables a salesperson to scan the barcode and quickly retrieve the details of the original transaction, for example: if a customer seeks to return or exchange goods or there is some other query.

If linked to a customer shop account, some retailers' point of sale systems also allow the salesperson to see a complete record of the customer's buying history. A receipt (or a copy of a receipt) is the proof of purchase usually needed to make a return and often plays a vital part in a company's return and exchange policy.

An invoice goes to the person responsible for paying the bill while the shipping list (or packaging slip) goes to the recipient. The shipping list is included in the shipped box. In some scenarios, the same person will pay the bill and receive the shipment. However, a person can buy and pay for a product and send it to someone else (e. g. a gift).

Shipping lists vary depending on the business and its products. Every shipment to a customer should contain a shipping list with the order date, the products included, and the quantity of each product. Some businesses may include the weight of each product. Many recipients use them as checklists when unpacking their shipments. If something they ordered is missing or shipped in error, they alert the seller.

Hand written or hand completed receipts are more often used for infrequent or irregular transactions, or for transactions conducted in the absence of a terminal, cash register or point of sale: for example, as provided by a landlord to a tenant to record the receipt of rent. They can also be required when company representatives buy goods, because tax deduction rules might require hand signed receipts.

Organizing receipts and similar financial documents is a multimillion dollar industry in the United States. Consumers can use both desktop and online software to organize electronic receipts; sometimes, receipts are sent digitally from point of sale devices directly to consumers. The growing trend of digital receipts has led to the launch of new businesses focused on digital receipt management.
