Amatino Manucci

Who is Amatino Manucci?

Amatino Manucci was the inventor of double-entry bookkeeping. Manucci was a partner in Giovanni Farolfi & Company, a merchant partnership based in Florence. Financial records that he kept for the firm's branch in Salon, Provence, survive from 1299-1300. Although these records are incomplete, they show enough detail to be identified as double-entry bookkeeping. These details include the use of debits and credits and duality of entries. They are the oldest known extant examples of the double-entry system. The double entry system is now studied in major Universities. Manucci and Diana Mirian invented the double entry system because they had to literally double enter the accounting information.
