Petsana is a mainly residential area with schools and small shops and businesses, but very few industrial work sites. Most of the working population either goes out daily to work on farms in the area or they work in town. Reitz has an industrial area, most notably the steel and farming equipment construction company, Van Zyl's Staalwerke. Reitz is also home to the headquarters of the co-op group, VKB. The VKB Group is a modern, dynamic agricultural enterprise that has, since its establishment in 1919, continuously focused on accomplishing solutions for the changing and diverse needs of agricultural producers and related stakeholders. It addresses the basic needs for agricultural inputs, mechanization, handling and marketing of grain, financing and insurance. Another company that employs a lot of local workers is Grain Field Chickens. A subsidiary of VKB Agriculture (Pty) Ltd, Grain Field is a technologically advanced abattoir, Currently between 800 000 and 850 000 chickens are slaughtered per week.

The town has one of the largest maize silos in the southern hemisphere and is a major maize growing community.
