What Is a Bill of Sale?

Key Points

A bill of sale proves ownership of items post-sale, valuable for vehicle and crop future sales.
There are absolute and conditional bills of sale, impacting the terms of ownership transfer.
For futures investors, bills of sale facilitate commodity trading like transferring grain ownership.

If you've ever bought something of significant value from or sold it to a stranger, you've probably used a bill of sale, even if you didn't know what it was at the time. Bills of sale can act as proof of ownership of items with significant value. That can be absolutely anything from cars to soybean futures. Read on to learn more about bills of sale and why they matter.

A share of stock represents ownership in a company, entitling holders to a portion of its assets, profits, and voting rights.

A bill of sale, also called a delivery instrument, allows you to easily transfer your soybeans, corn, or other commodity you're buying to the final buyer. So, for example, if you buy a grain silo full of wheat, you'll get a bill of sale from the farmer who grew the wheat. Since you don't intend to keep the wheat for personal use (it is a lot of wheat, after all), you'll be reselling it to someone who can use that much wheat.
