What are the ongoing expenses for a theatre company? The ongoing expenses for a theatre company are sizable. They include employees’ salaries, prop creation and costuming costs, building maintenance (if a company has a building), and the price of new scripts, among other costs. Who is the target market? A theatre company’s ideal customer is someone who enjoys live productions and has discretionary income. Such a person will be interested in seeing plays, and they’ll be able to afford to go to several shows each season.
