Many people will have no choice but to expand their business scope because of the trouble of issuing invoices. However, it should be considered that some business areas or industries have preferential tax policies, but adding redundant business areas may not necessarily enjoy preferential policies.

In addition, when distributing after-tax profits, some self-employed operators do not directly transfer money to their own personal accounts, but to other people's personal accounts. This kind of behavior has the risk of tax evasion. If it is monitored by banks and tax authorities while enjoying tax data, it will attract the attention of the tax bureau.
