My friends and I are going to cook together! What to pay attention to! The more detailed, the better.
In fact, your friend originally applied for individual business license, on the one hand, to save trouble, on the other hand, to avoid tax. So I suggest that if we cooperate, we can still keep the original license and then sign a partnership agreement, which can be notarized. If you feel that this still can't better guarantee your interests, then you should re-register the limited liability company and define the equity ratio according to your capital contribution.
