The European Economic Cooperation Organization has played a leading role in allocating funds, and it is also responsible for managing the movement of goods among countries. The payment for goods from American suppliers is paid by the European recovery plan fund of the buyer's country in US dollars. However, European importers do not get these goods for free, and they still need to pay in local currency (although they do not need to pay immediately, they can also pay by credit). The funds will be invested by the participating countries of Marshall Plan into the corresponding funds for the government to implement further investment plans.

In fact, from the beginning of the plan, most participating governments of the Marshall Plan knew that they would never have to return the corresponding funds to the United States. In the end, most of this balance was included in the national budget and has since "disappeared". But Germany is an exception. Unlike other European countries, the United States stipulated from the beginning that Germany must return all aid funds in the future. However, after signing the London debt agreement of 1953, the amount of aid that Germany has to repay has been reduced to $65,438 billion. Since July 195 1, Germany has received assistance equivalent to $270 million from the Marshall Plan, and they only need to repay1690,000 to the American Export-Import Bank in Washington. In fact, before 1953, the German government didn't know how much they needed to repay the United States. They stressed that aid funds only enter the private sector in the form of interest-bearing loans, so they can ensure that assets only increase rather than decrease. At the same time, as a lender, the bank should be responsible for supervising the whole loan process. These loans from Marshall Plan are mainly used to finance small and medium-sized enterprises. Until June, 197 1, the Federal Republic of Germany finally repaid the last aid debt to the United States in installments. Different from other countries, the funds used to repay debts are not from the European Reconstruction Fund of this country, but are specially allocated from the budget of the Federal Republic of Germany.
