In order to do business often huge investments are required and often a single person may not have that amount of financial means. Doing business through a company enables several people to invest and work together so that each individual may then enjoy the benefits of the activity carried out proportionately to the amount of work done and to the quota of investments made.
A participation (share or quota) of the capital of the company is assigned to the partner in return for the assets he has contributed.
During the life of the company, the founding partners or new partners may contribute new assets, for instance by increasing the capital.
The resources put into the company become assets of the company and the investor will never recover such resources and will have to wait until the company is wound up or if he no longer wishes to be partner of the company he may transfer his share to a third party or he may withdraw, where this is envisaged, but he will never recover the resources he transferred to the company.
