It depends on your boss's requirements. If the boss is expert and demanding, you need to write a financial analysis for him. If you don't ask for it, don't write it. According to my many years' experience, the boss doesn't ask for it, but he doesn't understand it very well and doesn't ask for much. Instead, you have to explain it and find yourself a job, which may not be rewarding.
However, you want your boss to know that you are doing a good job. When you report, you can talk about it roughly from the aspects of sales, expenses and costs. What the boss likes to hear most is how to reduce the cost. Assuming that the gross profit of catering enterprises can reach 51%, it is generally OK. If it is not achieved, you can make some suggestions from the aspect of purchase cost, and only grab a variety with higher purchase, and make suggestions. If it is the second, it is ok.
If the boss is not very picky, just explain one or two things to him at a time, so stop, because the matter of purchasing goods and spending money involves the boss's clique, and you can't go too far. The simplest thing is to talk about the report and tell him the report by project.
