It could be simple trading, bartering, or depending on the good, purchasing. A bartering economy is an economy that lacks money. Because there is no money, the agents in the economy only trade goods for other goods. This is called bartering. Calling it trade is a dictionary definition. Calling it purchasing is another dictionary definition, but could refer to how sometimes in a bartering economy one good becomes monetized (it acts like a currency).
