You have revealed too many problems. Not much to say, but just one point: you are just opening a store for the sake of opening a store!
I think, people just go to school - determine the industry based on interests and majors - start a business at the right time. This is all a journey, online and offline are completely different things, no matter how successful you are offline. None of these things are useful online! It is recommended that you visit the C store first.
As for Tmall you mentioned, the rules and operation methods are very same as those of C-store. So this is one of the reasons why I ask you to play in store C for a few months first.
About trademarks: The newly registered trademark belongs to TM. You can have someone register it for you. It usually takes at least 1 year to become all R. TM and R trademarks have different requirements and fees on Tmall.
About hardware: Opening Tmall must be branded. You must have a set of VIS, packaging materials with your own LOGO, and your own packaging. Computers will be added slowly according to personnel needs. It is recommended to have at least two network cables, as you will have understood before. It is best to have one for China Telecom and China Railway.
About the venue: Your own brand must be stocked, and the factory must have a warehouse when sending it back, right? Do you need a place to work? Customer service will work overtime after 10pm, so we need a place where people can live, right?
About personnel: First of all, you have to figure out, do you want to get involved or invest completely and ignore the technology? Operations, promotion, art, customer service, and warehouse management personnel. This is very basic, and you can wear multiple hats in the early stages!
Company registration: If there is a dedicated person to provide this service, register it on your behalf. The more registered capital the better, usually above 50W. You can also apply for corporate Alipay on Tmall three months after you officially get it. Registration usually takes one month to get it. To register a company, you need a lot of information about the office company address and Xiaoju property. It is recommended to work in an office building. It is very troublesome to register a company if you work in an ordinary community.
Do you still need to talk about getting the goods? You didn't even contact the factory, so you opened XX companies and XX Tmalls? If you want to take the goods back and put a trademark on them, I advise you not to do it. Tmall will charge you tens of thousands of dollars once you find out!
