ELI5: Why do soda companies shelf their own product in stores?

All other products(ice cream, motor oil, chips, etc) afaik have the store employees place the product on the shelf, but soda companies have their own employee that goes around to stores. Why is that?

EDIT:This post refers to American stores.

Beer distributors do this, too. Its mainly to get displays up properly and make sure stock is set out. They don't come back every day, though, so maintaining stock or a display neatly is largely the shop's responsibility.
