Many enterprises recruit office workers. What do they usually do? Is it different from the sales office?

I don't know what you mean by these two positions in the company. Each company has a different definition and division of labor for each position. Usually, business office is directly related to sales. Some companies call business people who sell in stores business offices, while others separate from sales people. Business office is mainly responsible for providing logistics support for business people, such as handling some company procedures, most of which are in offices or offices. The development direction is basically salesman, and then sales. The sales background is usually concentrated in the company's work area, which is mainly responsible for the statistics of sales data and the delivery of products. The development direction is basically the background supervisor, or administrative, human resources, accounting and other positions.

I wonder if the company you want to go to is also positioned in this way. You'd better ask the person in charge of recruitment in this company directly. They will give you a clear introduction to the positions in their own company and the differences between them. I wish you success in your work and career choice.
