I haven't cooked wonton, so I can only give you a general idea.
Your expenses, first of all, facade, your store can't be in the school cafeteria. Generally, the facade room around the school is about 1500 to 2000 per month, which is higher along the coast. You can't just work for three months and half a year, can you?
2, your joining fee and decoration fee are estimated to be tens of thousands (if you don't know the joining fee, you can only say so first)
3. Your daily cost of materials, dough, minced meat, water and electricity, personnel (two people in a small shop are not enough), 150 or so, depending on how much you sell.
4. Although it's a brand, it needs publicity when it just opened (let people nearby know that you are selling wonton, so come and pay more attention), and it also costs some money. 1500
5, since it is a catering industry, it is necessary to do business, health and communication, 5,000.
6, you need some liquidity in your hands when you do business, 3000
Junior, since you want to do catering business, you must be prepared for hardship, not to mention wonton, which can be sold three times a day. Business is ok, but it is very tiring.
Most of the business is difficult to kick in the first three feet. If you survive those difficult years, you will naturally get better. Since you have done it, you should make a difference and don't be anticlimactic.
