Hello, I am in the convenience store equipment business. The equipment alone will cost about 75 thousand. When you apply for industrial and commercial business license \ health certificate \ national tax \ local tax, 100 square can't be reported in real number, just hold 30-50 square, because tax deduction is calculated by square. Seriously, on your scale, it should be a community supermarket or a 24-hour convenience store. You should first consider what customer group your supermarket is positioned for, and what is the surrounding situation suitable for sale? Only in this way can we judge how much to invest. The community type is mainly based on the surrounding residents, and the convenience type is mainly based on long service time and convenience. Your problem can't be solved in one sentence or two. You should look up relevant information in many ways on the Internet. I've done many high-end convenience stores like yours myself, such as those with monitoring, and the one with lots near the community is estimated to be around 300 thousand. I hope I can help you.
