Why "Pacioli"?

Luca Pacioli (1445-1517) was an Italian mathematician and Franciscan friar who published the first comprehensive book on double-entry bookkeeping in 1494. His work, Summa de arithmetica, laid the foundation for modern accounting and is still used today. This tool honors his legacy by making financial document generation accessible to modern freelancers.
