1, if the investment is small and no one needs to pay, everyone can share the cost of capital equally, but the amount of capital contribution cannot be used as the basis for dividends;

According to the information you provided, I think technology and market play a decisive role in your industry, and these two factors can be used as the basis for dividends;

3. You have worked for 4 years and accumulated certain market resources and technical resources, which can be used as the original share capital to participate in dividends;

4. According to everyone's division of labor, that is, different positions (doing technology, management, marketing), the salary of each position can be determined with reference to the market price (note that this is not a dividend, of course, the internal salary can be determined according to the amount of completion, and one person can also have two positions at the same time), which can be deducted as a cost before dividends;

5. The balance after deducting the cost can be used as a dividend fund. According to your specific situation, you can pay dividends monthly, quarterly and annually. It is best to have a moderate time period and balance the off-season.

6. If you have to give a dividend ratio, my suggestions are: original shares 20%, technology 50% (divided by two people) and marketing shares 30%. Of course, you can arrange it yourself.

The second question: The first question has been answered.

The third person's question: whoever has strong management ability will do management. Of course, we should have a clear understanding of management ability and consider organization, planning, control, coordination and marketing. This should also be determined according to your actual situation. For example, when the market is relatively stable, technology is the decisive factor, and marketing is the decisive factor to expand the market.

I hope it helps you.
