Recording of financial transactions including sales, income, purchases and payments by an individual or an organization is usually known as 'Bookkeeping' in Greenfield. These recordings are done very systematically. The two most common bookkeeping types are single entry bookkeeping system and the double entry bookkeeping system. The bookkeeping method, that uses only income and payment accounts is known as Single-entry bookkeeping. It is recorded primarily in a revenue and expense journal. The above mentioned is also sufficient for many small businesses. The other method, double-entry bookkeeping usually requires recording of each transaction twice, using debits and credits. Bookkeeping is not only a career now, but also a subject considered in schools in Greenfield.
