First of all, if you want to write about management, refine it. You can write about financial management, human resource management and marketing of small and medium-sized enterprises.

Secondly, choose what you are familiar with or you can find more detailed information in these three aspects. I don't know much about financial management, so I can't give you advice. I study human resource management, and I am familiar with it. Combined with your study of SME management, you can write about the problems and countermeasures of SME recruitment, the design of SME career management planning, and the problems and countermeasures of SME employee training.

Thirdly, after determining your topic, look at your writing method. There are two writing methods: literature analysis and case analysis. Literature analysis is to find a lot of information, and it is all theoretical and basically conceptual. Case analysis is to take an enterprise and institution as a case, and put forward your solution on the basis of analyzing the problems existing in this enterprise and institution.

The most important thing is that you studied the management of small and medium-sized enterprises. No matter what you write, you should closely follow the concept and characteristics of small and medium-sized enterprises. In your thesis, you should include the concept and characteristics of small and medium-sized enterprises.
