It is very complicated to open a store in partnership, and now many family members, friends and classmates will make a lot of unhappiness when opening a store. I can't teach you how to be foolproof, but I will give you some advice by summing up my experience: 1. First, make clear the rights and obligations of both parties, just as the first floor said, we must sign an agreement, such as calculating the total investment of opening a store and then sharing it with both parties, so as to calculate the "shares" of both parties. Moreover, it is best to stipulate in the contract that public funds cannot be withdrawn casually and must be fixed after settlement. Secondly, whenever any problem involves money, it is especially unnecessary. Rent, contract deposit, decoration expenses and personnel expenses should be shared in a fixed proportion. Although it was a little troublesome, it was easy to talk in the end. Thirdly, at the beginning, we must promise each other that no matter what disputes occur and who caused them, we should bear them together, including some work-related injury compensation, site occupation, contract negotiation, lease owner's breach of contract, etc. Shareholders of both parties should discuss how to deal with it first, reach an understanding, and then negotiate with others to avoid final disagreement. 4. It is best not to involve other people during the partnership, such as introducing a friend to help manage and let someone become a shareholder, but to be honest, this situation is very common and it is really a headache when it appears. Need to negotiate with each other, what to do in case of leakage, how to share the responsibility and so on. In short, everyone's ideas are very different. More consultation and less arbitrariness can avoid a lot of unpleasantness.
