Investment in general rent (difficult to estimate due to geographical influence), decoration and equipment are large. If you can't do it, you need pre-training and study fees. At the beginning of opening a shop, you can spend less money without hiring people. I think this kind of shop, plus a workshop of about 30 square meters, is enough. Not counting the rent, it's almost 3W. Decoration can be simple and heavy, without luxury, but it must have taste, you know.
As for the prospect, I think it's great. I think young people generally prefer cupcakes, especially ladies. No one can resist the temptation of such a beautiful cake. It's just that there are really few things to sell in reality, but it's hard to buy if you want to eat. Moreover, this profit is quite high and the production is relatively simple. Shop positioning and decoration should be different from those common cake shops, so that there will be a market. Shop decoration and cake packaging must look good! I think this can reflect its exquisiteness!
Youku has a video about cupcakes, especially a happy dish: cupcakes. You can go and have a look. I hope it helps, because I like cupcakes, too!
