## Understanding the Sales Process

A sale happens when a seller transfers ownership of a product or service to a buyer for money or other assets. To complete a sale, both the buyer and the seller must agree to the specific terms of the transaction. These terms can include the price, quantity, method of delivery, and time of delivery.

Importantly, the good or service that is being offered must be available for exchange. The seller must have the legal authority to transfer ownership of the item or service to the buyer.

 If no compensation is received, the exchange is typically a gift or [donation](https://www.investopedia.com/terms/c/charitabledonation.asp), especially for tax purposes.

## Sale Example

When an individual purchases a first home, the sale occurs when the closing documents are signed, money exchanges hands, and the new owner gets the key.

However, many activities lead up to that final, legal exchange of money for property. These include the would-be buyer's contacts with a realtor and with a representative of a lending institution to obtain financing.

Additional sales can extend from the initial sale process. For example, once a home loan is made to the buyer, the lending institution may then sell that loan to another institution as an investment. The mortgage may eventually wind up in a bundle of similar investments called mortgage-backed securities, which are then sold on to other investors.

## What Are the Basic Elements of a Sale?

The elements of a sale might involve the request by a consumer to buy an item of interest from a seller. The seller could provide information about the product to the buyer, including price, quality, any warranty, and return policy.

The buyer and seller must agree on the terms of the sale. The buyer then provides payment and takes possession of the item.

## When Is a Sale Complete?

Normally, a sale is considered complete when the agreed-upon price is paid and the product is handed over to the buyer. This often includes a signed receipt as proof of the agreement.

## Can a Sale Involve Something Other Than an Exchange of Goods?

The word "sale" is commonly used to advertise a reduction in the price of goods or services to make them more attractive to potential buyers.

## The Bottom Line

A sale is a voluntary exchange of goods or services in exchange for payments. Sales can include anything from barter transactions to sophisticated trades on an electronic securities exchange. These free exchanges account for the majority of the world's economic activity and are essential to the functioning of the global marketplace.

To have a fair sale,the buyer and seller must agree to the terms of the exchange and the delivery of any other assets.
