Looking for a word describing what you are asking for in a trade

In commerce, if you are able to treat one side as the seller and the other as the buyer, then the buyer provides consideration for the seller's supply.

Consideration may be thought of as the concept of value offered and accepted by people or organisations entering into contracts. Anything of value promised by one party to the other when making a contract can be treated as "consideration": for example, if A signs a contract to buy a car from B for $5,000, A's consideration is the $5,000, and B's consideration is the car. - wikipedia

Here's an example of the terms in use:

• Consideration for a supply may be monetary or “in kind” in nature. - Department of Health, Queensland
