who invented the double entry system

The double entry system is most closely associated with the Italian mathematician and friar Luca Pacioli , who is widely credited as its “father” because he was the first to thoroughly describe and publish it in 1494.

Quick Scoop

• Luca Pacioli did not truly invent double entry from scratch; Italian merchants in cities like Venice and Genoa were already using similar methods in practice.

• In 1494, he published his famous book Summa de Arithmetica, Geometria, Proportioni et Proportionalità , which contained the first detailed, printed description of the double entry bookkeeping system.
