While there were definitely weaknesses in the Articles of Confederation as a plan of government, Congress was established and began to handle our business. Congress could make deals with other countries. Congress also established a system of money. Of course, Congress made laws.
Congress did a masterful job of dealing with western lands. The Land Ordinance of 1785 established a process for organizing and dividing western lands. It allowed the government to make money from the sale of these lands.
Congress also did a wonderful job of establishing a process of how a territory can become a state. With the Northwest Ordinance of 1787, Congress established a process that would be followed. This was needed since our country would be growing in the future.
